Adjusting The Cover Latches; Replacing The Drive Belt - Toro 30553 Operator's Manual

Adjusting the Cover Latches

If the cutting unit covers fit loose, the latch tension may be
adjusted by loosening the latch mounting screws and
sliding the latches (slotted mounting holes in the cutting
unit) to the proper position.

Replacing the Drive Belt

The blade drive belt, tensioned by the adjustable idler, is
very durable. However, after many hours of use, the belt
will show signs of wear. Signs of a worn belt are: squealing
when the belt is rotating, blades slipping when cutting
grass, frayed edges, burn marks, and cracks. Replace the
belt if any of these conditions are evident.
1. Position the machine on a level surface, lower the
cutting unit, engage the parking brake, put the traction
pedal in neutral, the PTO lever in the Off position, shut
the engine off, and remove the ignition key.
2. Release and unhook the latches securing the covers to
the top of the cutting unit. Remove the covers.
3. Loosen the 2 nuts securing the idler plate in place and
remove the old belt from the pulleys.
4. To install a new belt, the gear box base must be
removed. To do this, remove the 4 carriage bolts and
locknuts holding the gear box base.
5. Install the new belt around the gear box pulley, spindle
pulleys, stationary idler pulley, and adjustable idler
pulley (Fig. 37).
6. Install the gear box base with the carriage bolts and
locknuts.
7. Using a torque wrench, adjust the tension of the idler
pulley against the belt; refer to Adjusting the Idler
Pulley, page 23.
8. Install the covers and secure the latches.
