John Deere 25A Flail Mower
Features
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.
Power take-off (PTO) drive shaft and gearbox
Heavy-duty gearbox
PTO drive shaft
All mowers use a heavy-duty gearbox with a continuous rating of 65 hp.
The power is transmitted through fully shielded, telescoping drive shafts with quick-attach and detach characteristics for easy hookup.
36 flail-knife rotor provides uniform distribution of pulverized material
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.
