Setting The Depth
Tilling depth is controlled by the depth stake which can be adjusted to five different settings. See Figure 12. Adjust the side shields as shown in Figure 13, as you adjust the depth stake. Be certain spark plug wire is disconnected and grounded against the engine.
•When using the tiller for the first time, use the second adjustment hole from the top (1" of tilling depth). See Figure 12.

•When breaking up sod and for shallow cultivation, use the setting which gives 1" of tilling depth (second hole from the top). Place the side shields in their lowest position. For further depth, raise the
depth stake and side shields and make one or two more passes over the area.
•When tilling loose soil, depth stake may be raised to its highest position (use bottom adjustment hole) to give the deepest tilling depth. Raise the side shields to their highest position.
•To transport tiller, lower the depth stake (use top adjustment hole).
To adjust the depth stake, remove the clevis pin and hairpin clip. See Figure 12. Move the depth stake to the desired setting. Secure with the clevis pin and hairpin clip.
To adjust the side shields, remove the wing nuts. See Figure 13. Move the side shield to the desired position. Replace the wing nuts. Tighten securely.
Operating the Tiller
•Select the depth stake setting.
•Start engine as instructed on page 9.
•Move gear selection handle to one of the forward modes or reverse.
WARNING: Do not move the gear selection handle with the wheels or tines engaged.
Make certain the unit is stopped completely before changing the gear selection. A partial engagement may be necessary when engaging tines. Refer to “Know Your Tiller”
section on page 8.
•Squeeze the clutch handle against the handle to engage the wheels and tines.
NOTE: Make certain the gear selection indicator is correctly positioned before engaging the clutch handle. If it is between gears, the engine will stall.
To transport tiller, do not engage the tines. Select the wheel drive only.
WARNING: Do not push down on the handles so that the wheels are lifted off the ground while using the tine drive, or the tiller could move backward and cause personal injury.
For best results, it is recommended the garden be tilled twice (lengthwise, then widthwise) to pulverize the soil.
SECTION 5: MAKING ADJUSTMENTS
Handle Adjustment
The handle height may be adjusted. On Model 420 series, the handle may also be adjusted to be in line with the tiller, or swung to the left or right. Refer to the handle adjustment on page 8 for details of handle adjustment.
Belt Tension Adjustment
Periodic adjustment of the belt tension may be required due to normal stretch and wear on the belt. Adjustment is needed if the tines or wheels seem to hesitate while turning, but the engine maintains the same speed.
