Rotor and knives
A three-bank, counterbalanced rotor is equipped with 36 individually replaceable knives:
-
Rotor revolves at 1850 rpm to produce a 152.9-km/h (95-mph) blade-tip speed for a clean cut.
- Knives are arranged on the rotor to provide uniform distribution of material across the full cutting width.
- Knives pivot at their mounting points to minimize damage if an obstruction is hit.
Adjustable cutting height
Roller
The roller can be set at four different cutting heights, from 1.3 cm to 12.7 cm (1/2 in. to 5 in.) The tractor’s 3-point hitch upper link is used to regulate the cutting height between these positions.
