4.3  GROUND SPEED CONTROL ADJUSTMENT 

4.3.1. IDLER SPRING TENSION ADJUSTMENT 
Correct idler spring tension assures that mower will 
achieve fastest attainable speed when ground 
speed control lover is placed in ‘FAST’ position. 
1. Remove rear cover from mower.  Refer to 
Section “Rear Cover Removal & Installation”. 
2.  Idler spring tension is adjusted properly when: 
a. With lever in ‘SLOW’ position (see Figure 4.4), 
belt is relaxed, and idler spring on end of ground 
speed control cable has no extension. See Figure 
4.6. 
 

 
 
 
 
 
 
 
 
 
 
 
 
 

 
b. With lever in ‘FAST’ position (see Figure 4.4), belt 
is tight, and idler spring on end of ground speed 
control cable is extended approx. 1”. See Figure 
4.7. 
 

 
 
 
 
 
 
 
 
 
 
 
 
 

FIGURE 4.7 

 

To adjust idler spring tension:  
Loosen outer nut on end of ground speed cable, 
and run inner nut in toward cable (clockwise) or out 
from cable (counterclockwise) by 1/2 turn 
increments until correct adjustments are attained. 
See Figure 4.6. Be sure to tighten outer nut. 
3.  Replace rear cover. 
 
4.3.2. MINIMUM GROUND SPEED ADJUSTMENT 
If mower is traveling too fast or too slow when 
ground speed control lever is placed in ‘SLOW’ 
position, minimum ground speed can be adjusted.  
NOTE: Before adjusting minimum ground speed, be 
sure idler spring tension is adjusted correctly, as 
idler spring tension may affect minimum ground 
speed. Refer to Section “Idler Spring Tension 
Adjustment”. 
1. Remove rear cover from mower.  Refer to 
Section “Rear Cover Removal & Installation”. 
2. Place ground speed control lever in ‘SLOW’ 
position.  See Figure 4.4. 
3.  Adjust minimum ground speed: 
To decrease minimum ground speed: 
Remove end of idler spring from current adjustment 
hole, and relocate spring one hole closer to idler 
arm pivot bolt.  See Figure 4.7a.   
To increase minimum ground speed: 
Remove end of idler spring from current adjustment 
hole, and relocate spring one hole farther from idler 
arm pivot bolt. See Figure 4.7a.   
 

 
 
 
 
 
 
 
 
 
 
 
 
 

 
NOTE: After adjusting minimum ground speed, 
readjustment of idler spring tension may be 
necessary. 
4.  Replace rear cover. 
5.  Check minimum ground speed; repeat 
adjustment as necessary.
