SC40 Motor And Hose Assembly
Your skid steer Rotary Cutter is factory supplied with one
of two motors mounted to the deck. Make sure you check
gpm rating on the hydraulic motor decal to verify it
matches your skid steer’s gpm rating. Skip assembly
instructions below if the motor gpm rating matches your
skid steer.
See “Hydraulic Motor and Hose Bundles” on page 23
to properly select a motor that matches your skid steer.
Contact your Kubota dealer to order the motor.
