Choose the Right Farmry Disc Mower
Farmry’s DHM disc mower range gives tractor owners four cutting widths. Use the published tractor HP range as a starting point, then confirm PTO horsepower, rear lift capacity, hitch category and field conditions before choosing a model.
• DHM6 — 65 in., 4 discs, published for 35–80 HP tractors.
• DHM7 — 81 in., 5 discs, published for 35–85 HP tractors.
• DHM8 — 95 in., 6 discs, published for 45–100 HP tractors.
• DHM9 — 111 in., 7 discs, published for 45–100 HP tractors.
Match the Mower to Your Tractor
Engine horsepower and PTO horsepower are not the same. For a PTO-powered hay cutter, verify the tractor’s actual PTO rating, three-point hitch compatibility, rear lift capacity and 540 RPM PTO before ordering. Wider models also require enough tractor weight and stability for safe transport and field operation.
Choose Cutting Width for Your Field
A narrower 65–81 in. mower can be easier around gates, smaller paddocks and irregular field edges. A 95–111 in. mower can reduce passes on open acreage when the tractor has sufficient power, lift capacity and stability.
Use the Right Mower for the Job
Disc mowers are built to cut hay and forage crops such as grass, alfalfa and clover. They are not intended for woody brush, saplings, stumps or debris-filled areas. For pasture cleanup, weeds and light brush, compare Farmry flail mowers instead.Related collection: Farmry Flail Mowers
Disc Mower or Drum Mower?
Choose a disc mower when wider cutting capacity and field coverage are the priority. If you run a smaller tractor or want a simpler hay-cutting setup, compare Farmry’s drum mower range before deciding.

Are disc mowers good for cutting hay?
Are disc mowers good for cutting hay?
Yes. Disc mowers are designed for hay and forage crops such as grass, alfalfa and clover. After mowing, the crop may still need drying, raking and baling depending on your haymaking process.

Before use, inspect knives, fasteners, guards, PTO components and hydraulic connections.
