Working Width Important
Start by checking the working width. For very narrow plots, orchards, or small home farms, a 1.25m disc harrow (1BQDX-1.25) is ideal and compatible with 35–40 HP tractors. For a typical small farmland, the 2.0m model (1BQX-2.0) offers a balanced solution. Both models feature 460mm discs and are suitable for 35–40 HP tractors directly. Therefore, if someone asks what size disc harrow do I need for 40hp tractor, you can confidently advise: 1.25m for tight spaces or 2.0m for standard fields.
Weight & Height Counts
Most buyers focus only on width. However, weight and height are key to lifting performance and safety. An overly heavy harrow can overload the tractor's lift arm. A tall, unbalanced design poses safety risks on slopes. Our disc harrow for 40hp tractors features a lightweight yet durable frame that maintains a low center of gravity. It is easy to lift with the hitch, safe to transport, and stable during extended tillage sessions.
Why Generic Disc Harrows Fail To Match
Generic disc harrows are not made for a fixed tractor power level. They bring three hidden risks: too much width – heavy load on the engine and faster clutch wear; wrong weight – crushes the soil layer and blocks root growth; poor size matching – rough tillage and poor seedbed quality. All these farming results hurt. And they make your clients unhappy with your tractor packages.
