EP-3\u20135 Km\/h Tractor Soil Rotavator \u2014 PSW Series<\/h1>\n
The PSW series is a professional-grade rotavator<\/strong> designed for large-scale primary tillage and deep seedbed preparation across a working width of 3.20 metres. Available in three configurations \u2014 PSW-3200, PSW-3200 A, and PSW-3200 B \u2014 this tractor soil rotavator<\/strong> operates at a working speed of 3 to 5 km\/h driven by a tractor with a minimum engine output of 140 cv, making it one of the most capable heavy duty rotavator<\/strong> and high-output rotavator<\/strong> solutions available to professional farming operations, land contractors, and large-scale vegetable producers worldwide. With working widths available in four options ranging from 3.0 metres to 3.6 metres, the PSW series covers a broad spectrum of field conditions and tractor pairing requirements. The PSW-3200 B adds an integrated 2,000 kg-capacity fertiliser bunker, enabling simultaneous tillage and granular fertiliser application in a single tractor pass \u2014 a capability that sets it apart from conventional rotavator<\/strong> designs and delivers significant time and cost savings during land preparation campaigns. B2B buyers in South Korea’s commercial agriculture sector will find this agriculture tractor rotavator<\/strong> particularly well suited to the deep-tillage requirements of paddock preparation before transplanting and to the spring land preparation cycle that drives peak demand for high-output tillage equipment across the peninsula.<\/p>\n<\/div>\n The table below provides complete dimensional and operational parameters for all three PSW series rotavator<\/strong> models. Dimensional values are in millimetres (mm) unless otherwise indicated. Weight is in kilograms (kg). Working speed in km\/h; engine power in cv (metric horsepower). Use this data to verify tractor compatibility and transport logistics requirements before placing a purchase order.<\/p>\n PSW-3200 B requires 2 tractor hydraulic control valves for fertiliser bunker and metering system operation. All three models share the same category 2 bottom linkage and 3.20 m nominal working width. Working width options (3.0\u20133.6 m) are specified at order time.<\/p>\n<\/div>\n <\/p>\n <\/p>\n The PSW-3200 rotavator<\/strong> is a three-point linkage, PTO-driven tillage implement that combines deep soil fragmentation with a rear-discharge profile suitable for direct seeding passes or pre-planting bed shaping. Mounted on a category 2 bottom linkage, the PSW series connects to any tractor equipped with a standard rear three-point hitch and PTO output in the 140 cv and above power range. The machine’s 3.20 m working width \u2014 with available variants at 3.0 m, 3.2 m, 3.4 m, and 3.6 m \u2014 gives operators the flexibility to match the implement width to the row spacing or bed layout used in their cropping system, avoiding unnecessary headland passes and maximising field coverage per tractor hour with every rotavator<\/strong> pass. This flexibility is a key reason why the PSW series rotavator<\/strong> is the preferred rotavator<\/strong> choice among professional horticultural producers in South Korea, where precise bed widths for highland vegetable crops are a critical operational constraint.<\/p>\n The three model variants address different operational requirements within the same basic machine architecture. The PSW-3200 rotavator<\/strong> is the standard configuration, weighing 1,650 kg with a machine length of 1,880 mm \u2014 compact enough for operations where headland turning space is limited or where the tractor’s three-point linkage lift capacity requires a lighter implement. The PSW-3200 A extends the machine length to 2,300 mm and increases weight marginally to 1,665 kg, accommodating extended rear guidance systems or alternative rear attachment points for downstream implements. The PSW-3200 B adds the integrated fertiliser bunker system \u2014 a 2,000 kg capacity hopper feeding a precision metering unit \u2014 and increases overall machine length to 2,300 mm and height to 2,530 mm, with a corresponding weight of 1,800 kg. The PSW-3200 B requires two hydraulic control valves from the tractor to manage the fertiliser metering and hopper functions in addition to standard three-point linkage control, making tractor hydraulic compatibility an important pre-purchase check for buyers of this variant.<\/p>\n All three PSW variants share the same 3.20 m working width, 3,545 mm total machine width (including side guards and gearbox housings), and the same operating speed band of 3 to 5 km\/h, which represents the optimal balance between rotor tip speed, tine penetration angle, and forward travel speed for the rotavator<\/strong> to produce a fine, well-mixed seedbed tilth in loam and clay-loam soils. The working speed also determines the level of soil pulverisation achieved \u2014 a lower speed within the 3\u20135 km\/h band produces finer tilth at the cost of reduced field throughput, while a higher speed increases area coverage but reduces pulverisation intensity. Experienced operators calibrate forward speed to soil condition and target tilth quality \u2014 a judgement that becomes intuitive after a few field hours with this agriculture machine rotavator<\/strong>.<\/p>\n<\/div>\n <\/p>\n With working widths of 3.0 m, 3.2 m, 3.4 m, and 3.6 m available, the PSW series rotavator<\/strong> can be matched precisely to the row spacing, bed width, or field strip layout used in the buyer’s cropping system. This working width flexibility eliminates the compromise of using an oversized or undersized implement and ensures that the field coverage per tractor hour is optimised for the specific operation. For large-scale commercial producers in South Korea’s major vegetable and grain growing regions, selecting the correct working width can reduce total field preparation time by 15\u201325% compared with using a standard-width rotavator<\/strong>.<\/p>\n<\/div>\n The PSW-3200 B variant carries a 2,000 kg fertiliser bunker that meters granular fertiliser to the soil surface simultaneously with the rotavator<\/strong>‘s tillage action. Combining tillage and fertiliser application in one pass eliminates a separate spreading operation and ensures that fertiliser is incorporated into the tilled layer rather than left on the surface. This integrated approach reduces both fuel consumption and field traffic compared with sequential tillage and fertiliser passes, saving significant operating cost over a full cropping season \u2014 a compelling operational advantage for South Korean contract farming operations running multiple fields simultaneously during the spring preparation window.<\/p>\n<\/div>\n Specifying a minimum tractor power of 140 cv (approximately 138 hp) ensures that the PSW rotavator<\/strong> is always matched to a tractor capable of maintaining rated rotor speed and forward travel speed under load, even in heavy clay soils or after extended dry periods when soil hardness increases significantly. This power minimum also ensures that the tractor’s three-point linkage hydraulics can lift and control the PSW-3200 B’s 1,800 kg operating weight safely. For buyers running 140\u2013200 cv tractors in South Korea, this power requirement is easily met by the mainstream large-horsepower tractor models widely used in commercial farming operations across Gyeonggi, Chungcheong, and Jeolla provinces.<\/p>\n<\/div>\n The PSW series rotavator<\/strong> mounts on a category 2 bottom linkage \u2014 the most common three-point hitch standard used on tractors in the 100\u2013200 hp class worldwide, including the large majority of commercial farming tractors operating in South Korea. Category 2 linkage compatibility means no adapter kits or custom hitching arrangements are needed for most tractor pairings, reducing installation time, eliminating compatibility risk, and simplifying the specification process for dealers and distributors selling the PSW series to B2B buyers in Asian markets where standardisation on category 2 linkage is nearly universal in the relevant tractor power class.<\/p>\n<\/div>\n Operating within the 3 to 5 km\/h speed band allows this heavy duty rotavator<\/strong> to be tuned for different soil conditions and tilth quality targets by simply adjusting forward travel speed. At 3 km\/h, maximum soil pulverisation is achieved \u2014 suitable for fine seedbed preparation before transplanting or precision direct seeding. At 5 km\/h, field coverage is maximised with a coarser tilth still suitable for incorporation of crop residues and pre-planting primary tillage. This speed-based tilth control gives experienced operators an additional parameter to optimise, making the PSW series one of the most operationally versatile rotavator<\/strong> options available in its working width class.<\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/p>\n The PSW series rotavator<\/strong> \u2014 like all rotary-tine rotavator<\/strong> designs \u2014 operates on the fundamental rotary tine principle: the tractor’s PTO shaft transmits rotational power through a gearbox and chain or gear drive to a horizontal rotor shaft running across the full working width of the machine. Tines \u2014 L-shaped or C-shaped blades manufactured from hardened boron steel \u2014 are bolted to flanges on the rotor shaft in a helical pattern that ensures progressive soil engagement across the full working width rather than simultaneous full-width impact, which would otherwise generate excessive shock loading on the rotor drive. As the tractor advances and the rotor spins, each tine cuts downward and rearward through the soil, breaking up clods and mixing the profile through the tilling depth.<\/p>\n The relationship between rotor speed and tractor forward travel speed determines the “bite” that each tine takes as it passes through the soil \u2014 a smaller bite (higher rotor speed or lower travel speed) produces finer fragmentation and a finer finished tilth. At the recommended working speed of 3 to 5 km\/h, the PSW rotavator<\/strong> consistently delivers a well-graded soil particle size distribution suitable for direct seedbed use without requiring a subsequent secondary tillage pass. Processed soil exits through the rear of the machine beneath a soil-conditioning hood and rear scraper board, which further levels and firms the tilled layer to produce a consistent seedbed surface. The rear hood position can typically be adjusted to control the degree of surface firming and the profile of the finished bed, giving operators the ability to tailor the seedbed finish to the requirements of the subsequent planting or seeding operation.<\/p>\n For the PSW-3200 B variant, the fertiliser bunker and metering system of the rotavator<\/strong> operate in parallel with the tillage function. Granular fertiliser is metered from the 2,000 kg bunker by a hydraulically driven distribution system \u2014 controlled by the tractor’s first hydraulic control valve \u2014 and broadcast across the soil surface immediately ahead of the tine rotor. The tillage action of the rotavator<\/strong> then incorporates the fertiliser into the tilled layer, achieving thorough mixing and distribution through the soil profile. The metering rate is adjustable to match the agronomic fertiliser rate requirement of the crop being established, and the hydraulic drive allows the operator to start and stop fertiliser distribution from the tractor cab without leaving the seat \u2014 an important practical feature when managing headland turns and end-of-field applications.<\/p>\n<\/div>\n <\/p>\n The structural integrity of any heavy-duty rotavator<\/strong>, and of the PSW series rotavator<\/strong> in particular, depends on careful material selection throughout the machine. The main frame and cross-members are fabricated from heavy-section structural steel, welded to form a rigid assembly that resists the bending and torsional loads imposed during deep tillage in hard or stony soils. Key frame joints use full-penetration welds inspected to ensure structural continuity, and the frame surface is hot-dip galvanised or high-build epoxy coated to resist corrosion during outdoor storage between seasons \u2014 an important durability consideration in Korea’s humid summer climate where untreated steel welds can begin to corrode rapidly during the fallow storage period between spring and autumn tillage campaigns.<\/p>\n The rotor tines are the most critical consumable components of any rotavator<\/strong> and are manufactured from boron-alloyed steel heat-treated to achieve a hardness in the region of 45\u201355 HRC. This hardness range balances wear resistance against brittleness \u2014 harder tines resist abrasive wear in sandy or gritty soils, while tines at the lower end of the hardness range are tougher and more resistant to the bending impact loads that occur when the tine strikes buried stones or root masses. The tine bolt pattern of this rotavator<\/strong> allows individual tine replacement without removing the rotor assembly, which means routine tine maintenance can be carried out in the field using basic hand tools \u2014 a practical maintenance feature that significantly reduces machine downtime during peak tillage periods on South Korean farms where workshop time is at a premium.<\/p>\n The main gearbox housing is cast from ductile iron, which combines the casting geometry flexibility of grey iron with significantly improved impact toughness \u2014 an important property for a gearbox that absorbs the shock impulse loads transmitted when the rotor encounters buried obstacles. Internal gear sets are machined from case-hardened alloy steel and ground to achieve close tooth profile tolerances, minimising vibration and noise at operating speed. Gearbox seals are specified for the operating temperature range expected in Korean summer conditions, and the gearbox fill and drain points are positioned for easy access without removing the unit from the machine. The chain or side-drive transmission components of the rotavator<\/strong> are sealed in oil-bath housings to ensure consistent lubrication regardless of the machine’s operating attitude \u2014 a design detail that extends transmission life in the variable-slope conditions encountered when tillaging hillside paddocks in South Korea’s mountainous farming regions.<\/p>\n<\/div>\n <\/p>\n The PSW series rotavator<\/strong> \u2014 a true professional-grade rotavator<\/strong> \u2014 is designed for a range of professional tillage and land preparation tasks where consistent, high-quality seedbed preparation across large working widths is the primary requirement.<\/p>\n In commercial cereal and vegetable production systems, the rotavator<\/strong> is typically used as the final seedbed preparation pass before drilling or transplanting. The PSW series at 3\u20135 km\/h working speed produces a tilth quality suitable for direct seeding of most cereal and vegetable crops without requiring a secondary cultivation pass. For South Korea’s major upland crop areas \u2014 highland Chinese cabbage, radish, and garlic in Gangwon and Chungcheong provinces \u2014 consistent seedbed tilth is a critical quality factor that directly influences crop establishment uniformity and yield potential. The PSW agriculture tractor rotavator<\/strong> delivers this consistency reliably across the full 3.20 m working width in a single pass.<\/p>\n<\/div>\n After harvest, the rotavator<\/strong> provides one of the most effective methods for incorporating straw, stalks, and root debris into the soil profile. The rotor’s cutting action chops and mixes residue material through the tilled layer rather than simply burying it intact, which accelerates biological decomposition and avoids the formation of residue layers that can impede seedling root development. For double-cropping systems common in South Korea’s southern regions \u2014 where a summer paddy rice crop is followed immediately by a winter vegetable crop \u2014 rapid residue incorporation using a 3m rotavator<\/strong> or wider variant minimises the interval between harvest and re-planting, maximising the number of productive cropping cycles per year.<\/p>\n<\/div>\n Cover crops and green manures \u2014 phacelia, vetch, rye, and mustard being commonly used in Korean arable rotations \u2014 need to be incorporated into the soil before the main crop is established. The PSW rotavator<\/strong>‘s tine action effectively chops and mixes green biomass through the soil profile, providing both organic matter input and a functional primary tillage operation in the same pass. The PSW-3200 B’s fertiliser bunker adds the ability to apply basal fertiliser simultaneously, so the tillage, organic matter incorporation, and fertiliser application steps are consolidated into a single field operation \u2014 significantly reducing the total number of tractor passes required during the intense spring planting preparation period.<\/p>\n<\/div>\n In established orchards and vineyards, inter-row rotavator<\/strong> tillage manages weed competition, aerates compacted soil between tree rows, and incorporates surface organic matter from mown grass or fallen leaves. The PSW series working width options \u2014 particularly the 3.0 m and 3.2 m configurations \u2014 suit wider-spaced orchard and vineyard row arrangements, and the machine’s robust construction handles the root and stone burden typical of mature orchard floors. South Korea’s apple, pear, and grape producing regions in North Gyeongsang and Chungbuk provinces increasingly use mechanised inter-row management to reduce labour dependence in orchard operations, and the agriculture equipment rotavator<\/strong> is a central component of these mechanised systems.<\/p>\n<\/div>\n As South Korean agriculture adapts to shifting water availability and changing market demands, an increasing area of paddy rice land is being converted to upland vegetable and feed crop production. This conversion requires deep primary tillage to break up the impermeable hardpan layer that characterises paddy soils and to create the free-draining seedbed profile needed for upland crops. The heavy duty rotavator<\/strong> PSW series rotavator<\/strong>, operating at the lower end of the 3\u20135 km\/h speed range to maximise tillage depth and pulverisation intensity, is well suited to this conversion tillage task \u2014 providing the soil profile modification needed to transition from flooded rice cultivation to drained upland cropping in a manageable number of field operations.<\/p>\n<\/div>\n Agricultural contractors offering tillage services to multiple farm clients need a rotavator<\/strong> that delivers consistent, high-quality results across a range of soil types and field conditions without requiring constant adjustment or maintenance intervention. The PSW series rotavator<\/strong>‘s robust construction, straightforward operator controls, and wide working width make it a commercially attractive implement for contractors seeking to maximise productive hours per machine per season. The availability of the PSW-3200 B with integrated fertiliser bunker also allows contractors to offer a combined tillage-and-fertilise service, adding revenue per field visit and differentiating their service offering from competitors using conventional single-function rotavator<\/strong> machines.<\/p>\n<\/div>\n<\/div>\n<\/div>\n <\/p>\n Buyers of a rotavator<\/strong> for professional commercial use should be aware of the applicable national and international standards that govern PTO-driven rotavator<\/strong> implements, gearbox design, and agricultural machinery safety in their operating country.<\/p>\n South Korea \u2014 Agricultural Machinery Safety Act (\ub18d\uc5c5\uae30\uacc4\ud654 \ucd09\uc9c4\ubc95) & KMST<\/strong> \u2014 Agricultural machinery operated commercially in South Korea falls under the Agricultural Mechanisation Promotion Act. PTO-driven tillage implements including the PSW series rotavator<\/strong> are subject to safety assessment under the Korean Agricultural Machinery Safety Test (KMST) system. Buyers should confirm that the supplied machine’s PTO shaft guard meets Korean agricultural machinery safety standards, which align with ISO 4254-7 (agricultural machinery safety \u2014 rotary cultivators). For commercially operated rotavator<\/strong> equipment, compliance with the KMST assessment process is advisable before field deployment.<\/p>\n EU Machinery Regulation 2023\/1230 (successor to Directive 2006\/42\/EC)<\/strong> \u2014 European buyers or dealers importing this rotavator<\/strong> into the EU must ensure the machine carries a CE marking confirming compliance with the Machinery Regulation’s essential health and safety requirements. For PTO-driven rotary cultivators, this includes specific requirements on PTO shaft guard design and retention force (aligned with ISO 11684 safety sign requirements), rotor zone guarding, and the maximum exposed stub-shaft length at the tractor PTO coupling point. The gearbox and its mounting must additionally satisfy structural integrity requirements under the EHSR. Full technical documentation including a Declaration of Conformity must accompany CE-marked machines.<\/p>\n ISO 4254-7 \u2014 Agricultural Machinery Safety: Rotary Cultivators<\/strong> \u2014 This international standard specifically addresses the safety requirements for rotary cultivators including rotavator<\/strong> and rotary tiller designs. It covers rear-zone guarding, tine containment in the event of breakage, operator safety distances, and labelling requirements. Machines built to ISO 4254-7 meet the baseline safety requirements recognised in most global export markets and significantly simplify the regulatory compliance process for buyers and distributors outside the EU who need to demonstrate due diligence in equipment safety evaluation.<\/p>\n USA \u2014 ASABE S210 & OSHA CFR 1928.57<\/strong> \u2014 In the United States, agricultural machinery guarding requirements for PTO-driven equipment are governed by OSHA 29 CFR 1928.57 and the ASABE S210 standard for PTO shaft dimensions and safety. Buyers sourcing a rotavator<\/strong> for commercial use in the U.S. market should confirm that the PTO shaft connector dimensions comply with ASABE S318 and that the machine’s rotor guarding meets the containment requirements of OSHA 1928.57 for mechanically-powered tilling implements.<\/p>\n Australia \u2014 AS 2091 & State Agricultural Machinery Regulations<\/strong> \u2014 Australian commercial buyers of rotary tillage equipment must comply with AS 2091 safety requirements for agricultural machinery and with applicable state regulations governing machinery operation and transport. The rotavator gearbox must carry adequate oil sealing to prevent environmental contamination \u2014 a requirement that has become increasingly enforced under state environmental protection legislation governing farm machinery maintenance and storage practices.<\/p>\n<\/div>\n <\/p>\n <\/p>\n The PSW rotavator<\/strong> is designed as part of a complete power transmission system from the tractor PTO shaft to the rotor. We supply matched PTO shafts, gearboxes, and drive components to support the complete drivetrain, giving B2B buyers single-source access to everything the system needs.<\/p>\n A PTO shaft matched to the PSW rotavator<\/strong>‘s input torque requirement and tractor PTO output specification is essential for safe, reliable operation. The shaft must include a properly rated overrunning clutch or shear-bolt torque limiter to protect the rotavator<\/strong> gearbox in the event of rotor blockage, and a full-length guard complying with applicable safety standards. We supply compatible gearbox components and gear sets for the PSW series, including replacement gearbox internals for scheduled maintenance and field repair situations. Keeping a set of common spare gears on hand at the operating site significantly reduces unplanned downtime risk during peak tillage periods.<\/p>\n Browse our complete Gearbox and gear product range<\/a> for components compatible with PTO-driven rotavator applications.<\/p>\n1.
