Rotavator — 3.20 m Working Width

The PSW-3200 is the foundation of the range — a high-capacity rotavator delivering uniform deep tillage across the full working width. At 1,650 kg and 3.20 m standard width, it covers ground efficiently and produces a fine, even seedbed in one pass.

  • Working width available: 3.0 / 3.2 / 3.4 / 3.6 m — specify at order
  • 1,650 kg robust construction for long service life
  • Category 2 three-point hitch — fits standard 140 cv tractors
  • Working speed 3–5 km/h for optimal soil crumbling
  • Ideal for potato, sugarcane, grain and vegetable seedbed preparation

Rotavator — Extended Frame

The PSW-3200 A features an extended frame at 2,300 mm length — 420 mm longer than the standard model — providing additional structural rigidity for high-demand operations in heavy soils. At 1,665 kg, it is the preferred choice for deep tillage in clay and compacted soils.

  • Extended frame (2,300 mm) for increased structural rigidity
  • 1,665 kg — heavier build for clay and compacted soils
  • Same working width options: 3.0 / 3.2 / 3.4 / 3.6 m
  • Maintains 140 cv requirement — no tractor upgrade needed
  • Preferred for heavy clay soils and deep seedbed preparation

PSW-3200 B
Rotavator with Fertilizer Spreader — 2,000 kg Hopper

The PSW-3200 B combines deep rotavating with simultaneous fertilizer incorporation — one tractor pass completes both seedbed preparation and basal fertilizer application. The 2,000 kg capacity hopper handles full field applications without refilling on smaller plots.

  • 2,000 kg fertilizer hopper — basal application in one pass
  • Simultaneous rotavating and fertilizer incorporation
  • Extended frame 2,300 mm + increased height 2,530 mm
  • 1,800 kg — heaviest and most productive model in the range
  • 2 control valves required — for hopper and rotor hydraulics

Working Width Options

Four Width Options.
One Right Fit for Your Row Spacing.

All three PSW-3200 models are available in four working widths. Match the rotavator width to your row spacing and tractor track width for zero overlap and maximum efficiency.

3.0 米
Option A

Suits narrow row spacing and lighter tractors. Common in vegetable and orchard applications where headland turns are frequent.

3.2 m
Option B — Standard

The most popular width. Matches standard potato and sugarcane row spacing. Balances output rate with tractor stability.

3.4 m
Option C

Higher output for large-scale grain and sugarcane operations. Requires good field conditions and a stable 140 cv+ tractor.

3.6 m
Option D

Maximum output for large flat fields. Best suited to contractors covering high daily hectarages in open, stone-free terrain.

Applications

旋耕机 Applications

The PSW-3200 rotavator handles seedbed preparation across all major tropical and subtropical crops — from potato and sugarcane to orchards and pasture renewal.

Rotavator machine potato field seedbed preparation deep tillage
Potato
Potato Field Seedbed Preparation

Deep uniform tillage to 200+ mm creates the loose, stone-free seedbed that maximises potato tuber development. The PSW-3200 completes full-width preparation in one pass — critical for planting schedules where timing is tight.

Rotavator machine sugarcane field soil preparation tillage
Sugarcane Planting Preparation

Breaks compaction layers from previous crop, incorporates crop residue, and creates a uniform planting tilth in one pass. The 3.2–3.6 m width options match standard sugarcane inter-row spacing for efficient field coverage.

Rotavator machine grain crop soybean corn seedbed preparation
Grain Crops
Soybean & Corn Seedbed

High-output tillage for large-scale grain production. At 3–5 km/h working speed, the PSW-3200 covers 9,600–16,000 m²/hour in the 3.2 m configuration — keeping pace with modern planting schedules.

PSW-3200 B rotavator fertilizer spreader combined operation
Combined Operation
Rotavating + Fertilizer Incorporation

The PSW-3200 B's 2,000 kg hopper applies basal fertilizer directly into the tilled layer — eliminating the separate spreading pass. Fertilizer is incorporated uniformly at rotor depth rather than sitting on the surface.

Rotavator machine pasture renewal grassland tillage
Pasture
Pasture & Grassland Renewal

Incorporates old sward and weed growth into the soil profile, breaking compaction layers formed by livestock traffic. Produces a clean, level seedbed for grass reseeding without herbicide-only renovation programmes.

Rotavator machine orchard vineyard inter-row soil management
Orchards & Vineyards
Inter-Row Soil Management

The 3.0 m width option fits standard orchard and vineyard row spacing. Manages cover crops, incorporates organic matter, and maintains a clean, aerated inter-row zone without damaging surface feeder roots.

PSW-3200 Series — Full Comparison

All three models share the same rotor system, working width options, and 140 cv tractor requirement. The differences are frame length, weight, and the PSW-3200 B's integrated fertilizer hopper.

FAQ

Rotavator Machine — Common Questions

Questions we receive most often before purchasing a PSW-3200 rotavator.

What is the difference between PSW-3200, PSW-3200 A, and PSW-3200 B?
The PSW-3200 is the standard model with a 1,880 mm frame — compact and suited to standard tillage in lighter soils. The PSW-3200 A has an extended 2,300 mm frame and 15 kg more weight for increased rigidity in heavy clay and compacted soils — same tractor requirement, no other changes. The PSW-3200 B uses the same extended frame as the A but adds a 2,000 kg capacity fertilizer hopper and requires 2 hydraulic control valves — allowing simultaneous tillage and basal fertilizer application in one pass.
Which working width should I choose for potato cultivation?
For potato cultivation, match the rotavator working width to a multiple of your row spacing. Standard potato row spacing is 75–90 cm, so 3.0 m covers 4 rows at 75 cm spacing, and 3.6 m covers 4 rows at 90 cm spacing. The 3.2 m option is the most popular for potato — it is a clean multiple of 80 cm spacing (4 rows) which is common in medium-scale potato operations. If you are using a Watanabe potato planter on the same tractor, choose the rotavator width that matches your planter's row configuration.
Can the PSW-3200 B apply any fertilizer type, or only specific products?
The PSW-3200 B hopper handles granular fertilizers — NPK compounds, single superphosphate, potash, and urea. Fine powder fertilizers and sticky or hygroscopic products may cause bridging in the hopper. Liquid fertilizers are not compatible — a separate liquid injection system is required for those. The application rate is adjustable to match your agronomic requirement. Contact us with your fertilizer type and target application rate and we will confirm compatibility before purchase.
What working depth does the PSW-3200 achieve?
Working depth is adjustable via the rear roller and is typically set between 100–250 mm depending on crop requirement and soil condition. For potato, 200–250 mm is standard to allow full tuber development. For sugarcane and grain crops, 150–200 mm is common. Shallower settings (100–150 mm) suit cover crop incorporation and inter-row management in orchards. The rear roller controls the depth and also firms the seedbed surface for uniform germination.
Can the PSW-3200 work in stony soils?
The PSW-3200 can work in moderately stony soils, but surface rocks above 80–100 mm diameter significantly increase tine wear and risk rotor damage. For stony fields, we recommend first clearing surface rock with a Watanabe Rock Rake (EW-4000) or Rock Picker (CT-2100) before rotavating. This sequence — stone removal followed by rotavating — is the standard approach for converting rocky farmland to productive cultivation and is why both machine types are available in the Watanabe range.
