When checking tension without a force measuring device, the belt, when properly set, should feel very tight.
Cycle belt through at least two revolutions after any adjustment before checking tension. These belts are very strong and need to be adjusted very tightly. Belts are more likely to be damaged by excessive slippage than from being overtightened.
Minor tension adjustments are made by moving the idler pulleys up or down. Major tension adjustments are made by moving the mower deck forward and rear- ward.
IMPORTANT
■Alignment must be rechecked if it is necessary to move idler pulleys or the mower deck to get proper belt tension.
■Tension on a new belt should be readjusted every half hour for the first two hours and then checked every eight hours of operation.
Rear Belt Shield Installation
Place stud welded on bottom of belt shield in small front hole of idler bracket drawbar.
Install clevis pin through belt shield brackets and top link bracket.
Secure with safety pin.
OPTIONAL EQUIPMENT
A leaf mulcher, low suction blades,
Blades
Low suction and extra suction blades are optional for this mower. In sandy areas where abrasive action could cause excessive blade wear, low suction blades are recommended.
Extra suction blades are designed to lift up fragile downed grasses for better cutting results. They are also recommended for use with leaf mulcher attach- ment.
Casters
Casters are used to adjust cutting height.
Mount casters on mowers to the outside deck rails and over side shield or discharge chute. Attach rear of caster arm in fourth hole from front of deck rail with a 3/8" x
Attach the right and left adjustment brackets, offset down and inward, and in front hole as shown in Figure 25 on each side of the deck angle and inside side skid. Use two 1/2" flat washers as spacers at the rear side skid hole.
Select the desired cutting height and install adjustment brackets to caster arm with 1/2" x
Adjust side skids to ride at least 1/2" above ground level.

Front Roller
The front roller should be used when scalping occurs. Side skids and casters effectively reduce scalping in most cases. You may encounter areas where the side skids or casters will drop into depressions and allow the center of the mower to contact the ground and scalp. When this occurs you should install a front roller in the center of the mower.

See Figure 28. Place and secure mower in vertical position to make front roller installation easier.
