PSW-3200B Rotavator

🌱 5-in-1 Operation — Unique in Class

Till, bury stones, crush clods, level the seedbed, and apply fertilizer or seed — all in a single pass. This replaces five separate field operations with one machine, eliminating the need for a separate spreader or seeder pass. The time savings, fuel reduction, and reduced soil compaction from fewer passes are transformative for large-scale operations.

🗃 2,000 kg Integrated Bunker

The massive 2,000 kg capacity bunker holds enough granular fertilizer, lime, or grass seed for extended working runs without refilling. This means fewer stops, higher daily coverage, and consistent nutrient application across large areas. The hydraulically controlled metering system ensures even distribution across the full 3.2 m width.

🔮 Extended Sorting Zone — Premium Finish

The 2,300 mm extended body provides the same superior stone-burying and seedbed-finishing performance as the PSW-3200A. More internal separation distance means deeper stone burial, finer surface texture, and a thicker stone-free topsoil layer. Fertilizer or seed is applied directly into this premium-quality tilled surface.

🛠 Wide 3.2 m Working Width

Cover 3.2 meters per pass at 3–5 km/h, delivering approximately 1.0–1.6 hectares per hour of simultaneously tilled, stone-buried, and fertilized seedbed. For large arable fields, commercial turf projects, and time-critical contracts, this single-pass productivity is unmatched.

💰 Replaces Multiple Machines

The PSW-3200B eliminates the need for a separate rotary tiller, stone burier, harrow, roller, and fertilizer spreader. That is five machines reduced to one — dramatically lowering your total equipment investment, storage requirements, and annual maintenance costs. Factory-direct pricing makes the economics even more compelling.

💪 Cab-Controlled Application Rate

The 2 double-acting hydraulic remotes give the operator full control of the fertilizer metering rate from the tractor cab. Adjust the application rate on the fly as soil conditions or nutrient requirements change across the field — no need to stop and manually recalibrate. The system handles standard granular fertilizers, lime, grass seed, and other dry amendments.

⚡ Nutrient Placement Into Freshly Tilled Soil

Unlike broadcast spreading onto an unprepared surface, the PSW-3200B applies fertilizer or seed directly into the freshly tilled and sorted soil — where the rear roller immediately presses it into the seedbed. This ensures superior nutrient incorporation, better seed-to-soil contact, reduced surface run-off of fertilizer, and more uniform germination. Agronomically, this is the ideal nutrient placement method.

🌾 Large-Scale Agriculture – Seedbed + Fertilizer in One Pass

For cereal, oilseed, potato, and vegetable growers working stony land at scale, the PSW-3200B creates a stone-free seedbed and applies base fertilizer simultaneously. No need for a separate spreader pass — saving an entire tractor operation, fuel, labor, and significantly reducing soil compaction. The 2,000 kg bunker capacity means extended runs between refills, keeping the operation moving across large acreages.

⚽ Sports Turf – Seedbed Preparation + Grass Seeding

For new football pitches, rugby fields, golf courses, and equestrian arenas, the PSW-3200B prepares a premium stone-free surface and seeds it with grass in a single pass. The seed is deposited directly into the freshly tilled soil and pressed in by the roller — providing ideal seed-to-soil contact for fast, uniform germination. This eliminates the separate seeding pass and reduces the time from bare ground to established turf.

🏗️ Landscaping – One-Pass Ground-to-Garden

Commercial landscaping projects — residential estates, hotel grounds, corporate campuses, public parks — require rough or stony ground to be converted into a plantable, nutrient-enriched surface. The PSW-3200B achieves this in a single pass: tilling, burying debris, applying starter fertilizer or grass seed, and rolling the surface. The client sees results faster, and the contractor saves on equipment and labor.

🌳 Land Reclamation & Revegetation

Post-mining, brownfield, and deforested sites often need both soil preparation and immediate revegetation. The PSW-3200B processes raw ground, buries stones and rubble, and applies grass seed or soil amendment in one pass — accelerating the revegetation timeline and reducing erosion risk on exposed sites. The 2,000 kg bunker capacity handles the high seed or lime application rates typical of reclamation projects.

🏛️ Municipal Green Space – Till, Lime, Seed in One Operation

Municipal crews establishing new parks, cemeteries, school grounds, or roundabout planting can till the ground, apply lime or starter fertilizer, and broadcast grass seed in a single pass. This drastically reduces the number of machine operations on public sites — minimizing disruption, traffic management costs, and the time public areas are closed for works.

Q1: What is the key difference between the PSW-3200B and the PSW-3200A?

The PSW-3200B adds an integrated 2,000 kg fertilizer and seed bunker with hydraulic metering control. It requires 2 double-acting hydraulic remotes (the PSW-3200A requires none). Both share the same extended 2,300 mm body, 3.2 m working width, 140 hp PTO drive, and premium stone-burying capability. Choose the PSW-3200B when you need to apply fertilizer, lime, or seed simultaneously with soil preparation.

Q2: What materials can the bunker dispense?

The bunker handles any dry, free-flowing granular material including: granular NPK fertilizer, urea, lime, gypsum, grass seed, clover seed, wildflower seed mix, and dry soil amendments. The metering system is adjustable to accommodate different granule sizes and application rates. Liquid fertilizers and slurry are not compatible.

Q3: Can I use the PSW-3200B without filling the bunker?

Yes. With the bunker empty and the metering system disengaged, the PSW-3200B functions identically to the PSW-3200A — a pure stone burier and rotary tiller. You only fill the bunker when simultaneous fertilizer or seed application is needed. This gives you the flexibility of two machines in one.

Q4: What tractors are compatible with the PSW-3200B?

Any tractor with at least 140 hp, a 540 rpm PTO, a Category 2 three-point hitch, and 2 double-acting hydraulic remotes. The rear axle must support the 1,800 kg empty weight plus up to 2,000 kg of bunker payload (3,800 kg total when fully loaded). Popular models include John Deere 6R/7R, New Holland T7, Case IH Puma, Fendt 500/700 Vario, Massey Ferguson 7700, and Claas Axion series.

Q5: How many hectares can one bunker load cover?

This depends entirely on the application rate. For example: at a typical base fertilizer rate of 300 kg/hectare, a full 2,000 kg bunker covers approximately 6.5 hectares. At a grass seed rate of 30 kg/hectare, the bunker covers approximately 66 hectares. At a heavy liming rate of 1,000 kg/hectare, coverage is approximately 2 hectares per load.

Q6: Are the rotor blades replaceable?

Yes. All rotor blades are individually bolt-on and replaceable without removing the rotor. Typical service life is 150–400 operating hours. We supply replacement blade sets at competitive prices with fast international shipping.

Q7: What size stones can the PSW-3200B bury?

The PSW-3200B buries stones from gravel up to approximately 100–150 mm. For larger stones, we recommend a first pass with a rock rake or stone picker, then a finishing pass with the PSW-3200B for simultaneous seedbed preparation and fertilization.

Q8: Is the application rate adjustable while driving?

Yes. The 2 double-acting hydraulic remotes provide full cab control of the metering system. The operator can adjust the application rate on the fly without stopping — responding to changing soil conditions or nutrient requirements across the field.

Q9: Do you ship the PSW-3200B internationally?

Yes, we export worldwide. Production takes 15–20 days, with transit depending on destination. We handle all export documentation and offer CIF or FOB pricing. Please contact our sales team for a detailed quotation.

Q10: What routine maintenance does the PSW-3200B require?

Routine maintenance includes: checking gearbox oil level every 50 hours (change at 200 hours); greasing all bearings and PTO driveline every 8–10 hours; inspecting blade condition and replacing worn blades; checking chain/gear drive tension and slip clutch adjustment; cleaning the fertilizer metering mechanism and bunker interior after each use to prevent residue buildup and corrosion; and inspecting hydraulic hoses and connections. Flush the bunker and metering system with clean water if corrosive materials (such as lime) have been used.
