What Size Rotary Tiller Do You Need for Your Tractor?

Choosing the correct rotary tiller size is crucial for efficient soil preparation and equipment longevity. The wrong size can overload your tractor or reduce productivity.

🚜 Key Factors to Consider

1. Tractor Horsepower (HP)
As a general guideline:

15–25 HP → 3–4 ft tiller
25–40 HP → 4–5 ft tiller
40–60 HP → 5–6 ft tiller
60+ HP → 6–7 ft or larger

Always match tiller width with your tractor’s PTO power capacity.

2. Field Size
Large farms benefit from wider tillers for faster coverage. Smaller plots require compact models for maneuverability.

3. Soil Type
Hard or clay-heavy soils require stronger gearboxes and reinforced blades.

4. Working Depth Requirement
Standard tillers operate 4–6 inches deep, while heavy-duty models can go deeper for intensive land preparation.

⚖ Best Practice

Ideally, your tiller should cover slightly wider than your tractor’s rear tire width to avoid unprocessed strips of soil.
