2. Sit on the seat, start the engine, and lower the center
cutting unit until it is slightly off of the floor.
3. Secure the height-of-cut chains to the rear of the cutting

Tensioning the Cutting Unit
Drive Belts
Check the condition and tension of the cutting unit drive
belts initially after 8 hours of operation and every 50
operating hours thereafter.
The proper belt tension will be attained when a force of
45 lb. on a used belt (90 lb. on a new belt) is applied to the
idler pulley (Fig. 77) when sliding it into the belt.
