Known problems

Rotor removal tool

Repair guides

PTO slip clutch: checking, freeing and setting (Tomahawk 8100 and 404) (Moderate, 1–1½ hours): Clutch slipping at every start, smell of burning, clutch seized after a long idle, or no drive.
Blades, hammers and drive belts (Tomahawk 404 / 505) (Moderate, 1–2 hours): Poor shredding, vibration, blades or hammers blunt, belt slipping, or booster fan noise.

The full step-by-step guides are in Farmyard Workshop once you add your implement.
