2-3 Belt Installation
Loosen the two bolts that secure the gear box
assembly to the PTO mount plate. (Figure 6) Loosen
the adjustment bolt until the gear box assembly is at
its far left adjustment (the gear box is moved
towards the mower’s engine pully). Install the Kevlar
cord belt from the engine pulley to the lower gear
box pulley. To tension the drive belt, turn the adjust-
ment bolt clockwise until there is 1” of deflection,
with 10-11 lbs. of pressure between the engine pul-
ley and the gear box pulley. Once the correct ten-
sion on the belt is achieved, tighten the (2) bolts that
secure the gear box assembly and re-attach the
shield. (Figures 6 and 7)
