Do not allow children to operate this machine. 

 

 

 

Slow down and watch the ends of the mower when making turns so objects are not 
struck and/or run over.

 

 

Look down, to the sides, and behind before and while backing to avoid backing over 
something or someone.  Care should also be taken while backing so that the mower 
does not jackknife and damage hitches.     

                           

Stop the mower blades on the mower if the tow vehicle becomes stuck or stops 
going forward because of loss of traction.  Shut off the engine on the mower before 
attempting to push or pull the tow vehicle. 

 

Listen to the rough cut mower engine while mowing.  The engine should run free and not work too 
hard.  Working the engine too hard will cause overheating and premature failure. 

 

If the mower’s engine dies while in use, remove the rough cut mower from the uncut 
area before attempting to engage the clutch.  Inspect the blades for any 
obstructions that may prevent blade engagement.  Failure to follow these 
instructions may result in premature belt failure or a fire. 

 

 

Do not allow material to build up on the air inlet to the engine cooling system.  Special care should 
be taken to make sure the engine is getting enough inlet air.  Do not allow the engine cooling fins 
under the shroud to be blocked.  If air flow over the engine is restricted, the engine could 
overheat. 

 

F. 

DRIVE BELT REMOVAL AND TENSION – 

Refer to Figure 7

 

 

Shut off engine and allow mower blades to stop turning before making any 
adjustments or repairs. 

 

Remove the safety shields. 

 

Loosen the nuts on the spring-loaded idler; adjust bolt until the belt can be slipped off the idler and 
drive sheaves. 

 

Slip the belt down under the drive sheave and off the blade spindle sheaves.   

 

Install the new belt and then adjust the tension as follows:  

See Figure 7.  

Take special care to 

make sure that the belt is placed between the brake stud and the idler pulley. 

 

With the clutch engaged, adjust the nuts on the spring-loaded idler adjuster bolt until the length of 
the spring is between 2” and 2-1/8”.  This is the initial belt break in spring length.  When the belt is 
broken in after several hours of mowing, the running spring length should be between 2-1/4” and 
2-3/8”.  For maximum belt life, periodic checks every 3-4 hours should be done to make sure the 
spring length has not exceeded the recommended running length.
