Deck Drive Belt Adjustment

Land Pride

Section 3: Adjustments

Table of Contents

The spindle belt remains in constant tension by means of a spring tensioned idler. The spring tension should be adjusted so that the belt does not slip under normal operating load conditions and may require readjusting as the belt stretches and wears. The belt should be replaced if it is excessively worn or damaged.

Refer to Figure 3-6and Figure 3-7:

Check spring length to verify if belt is tensioned correctly. Installed spring length should be 4 3/4" +or- 1/8". Vary the spring length by adjusting the length of the eye bolt.

Engine RPM Setting

The Razor is designed so that the engine will run at 3600 rpm static pump load only. At this speed the hydraulic pumps are running at their maximum rated speed.

Deck Leveling & Height Adjustment

The mower deck has three areas that may need to be checked and adjusted periodically. Before considering any mower deck leveling adjustments, check that the tire air pressure is within the specified range.

!WARNING

Stop engine. Make sure blade engagement switch is in the down (OFF) position. Place control levers in park position before leaving machine.

Deck Level Adjustments

Leveling the deck must be done in the following order:

Spring

Anchor

Bracket

2. Park the unit on a flat surface.

Refer to Figure 3-8:

3.	Raise deck fully up.
4.	Position the blade cutting height at 3 1/4” by placing
	3" high deck support blocks under the deck edge in
	three locations:
	a. Place two of the 3" support blocks under the deck

Excessive belt tension may lead to premature damage of belt and drive components and is also a safety hazard to the operator and bystanders. Not enough belt tension may also lead to premature belt damage due to excessive belt slippage.

IMPORTANT: Do not over tension the spring to compensate for a badly worn belt or pulley.
