BELTS AND PULLEYS
This saw uses a pair of Blade Shaft Drive Belts (5G 3VX
530) and a Hydrostatic Pump Belt (AX-35).
V-Belt Tension
The V-belt tension on this saw is automatically controlled
by the hydraulic system that actuates the blade shaft
engage/disengage system. Hydraulic pressure exerted on
the engine tilt cylinder applies force on the belt drive system
to engage blade shaft rotation.
