Your tiller is a precision built machine designed for seed 
bed preparation, cultivating, furrowing and mulching. It 
is engineered to minimize the hardest work in the 
vegetable or flower garden, to till the soil for planting 
and cultivating, and to perform many other useful labor 
saving tasks in the garden.                                                

With the proper amount of care and maintenance, this 
machine will provide the owner with many years of 
service.

The tiller is shipped with the wheels adjusted such that 
the unit sits level. While tilling, as the tines enter the 
ground and the front of the tiller lowers, the wheels 
must be raised to level the unit, which is essential for 
proper engine operation. This adjustment is made by 
removing the clevis pin and hairpin clip from wheel 
yoke, raising the wheels to the desired height, and 
replacing the clevis pin and hairpin clip.  See Figure 9.

 

The end cap, which are used to avoid tilled soil from 
overflowing onto unwanted areas, are removable from 
the outer axle. Remove the hairpin clip and clevis pin 
that is securing each end cap and slide end cap off the 
axle. See Figure 10.
