1-2 DESCRIPTION
The Razorback Rotary Cutters (Figure 1-1) are light
duty cutters intended for cutting grass and small
brush up to 1” diameter. Each cutter has two 3/8 x 3”
blades that are free-swinging to reduce the shock of
impact when a stationary object is hit. A 1/2 x 3”
Grade 2 shear bolt protects the gearbox and drive-
line from damage. The 40 HP gearbox is designed
for 540 RPM input speed giving the blades a 12,468
ft./min. tip speed. Front and rear discharge shields
are included as standard equipment. (Note: Dealer
or purchaser may elect to delete at their option)
Total weight of the machine is 450 lbs.
