Section 3 - ADJUSTMENTS & REPAIR
3.4 TILLER TINES |
Your Snapper Tiller has right hand and left hand |
tines. Replace both tines if blades become bent or |
are badly worn or otherwise damaged. Use correct |
1/4” TO 1/2”
Snapper replacement tines. The tines are secured |
to the tine shaft with a shear bolt, Part No. |
and Lock Nut Part No. |
Two extra nuts and two bolts come with tiller. Keep |
spares on hand in case a bolt shears off or |
becomes lost while tilling. See Figure 11. DO NOT |
over tighten these shear bolts as this will cause |
premature failure. (Recommended torque is 5 to 8 |
foot pounds maximum). NOTE: Failure to use the |
correct shear bolts could result in serious damage |

3.5BELT ADJUSTMENT - REPLACEMENT
BELT TENSION ADJUSTMENT: Remove the cotter pin that secures clevis pin to left wheel hub. Remove clevis pin from left wheel hub and slide wheel out on axle about 1”. Remove belt guard. Measure the length idler pulley spring at the end of the control cable in a relaxed position. Then move wheel and tine control bail up to the handle bar and measure the extended length of the spring. When properly adjusted, the spring will extend 1/4” to 1/2”. See Figure 12. To adjust, loosen and reposition the two jam nuts on the threaded end of cable located on the dash panel. Move jam nuts toward the end of threaded end of cable for more tension. Move jam nuts in a direction away from the end of threaded end of cable for less tension. See Figure 13. After adjustment, retighten both jam nuts against dash panel. Reinstall belt guard. Slide wheel back into operating position and reinstall clevis pin and secure with hair pin.

3.5.1TENSION TEST: Start the engine with tiller in neutral. Shift transmission into FWD & TILL and pull the wheel and tine control bail up against the handle bar. Tines and wheels will start to rotate. Release control bail. Tines and wheels should stop rotating immediately. If rotation continues after release of control bail then clutch spring tension is to great and will have to be readjusted as described in BELT TENSION ADJUSTMENT Section.
3.5.2BELT REPLACEMENT: Pull the clevis pin from the left wheel and slide the wheel out 1”, remove belt guard and then the old belt. NOTE: Replacement belt must go over the top of the idler and be within the belt guide as shown in Figure 14. Check belt tension as described in BELT TENSION ADJUSTMENT Section. Reinstall guard, push left wheel back into position and secure with clevis pin and insert and secure cotter pin.
