Installing Rear Wheels and Axle Shaft
NOTE: Some lawn mower models covered in this operators manual are shipped with the rear wheels and
axle shaft already installed on the unit. If your mower is one of these, proceed to the next sub-section now.
Block the rear of the mower securely. Move rear height adjusters to the highest position. For location and
description of these height adjusters, refer to the Controls section of this manual.
Note that the right side of the axle shaft has two tabs and the left side has one tab only. See Figure 8.
Identify the right and the left side of the rear axle shaft before proceeding to install.
Slide the left side of the rear axle shaft through the right pivot bar as shown in Figure 8.
Rotate the axle shaft until the first tab on the right side of the shaft clears the keyed hole on the pivot bar.
Rotate further until the second tab on the right side of the axle shaft locks into the hole in the pivot bar
and the tab on the left side of the axle shaft touches the surface of the left pivot bar.
Insert a spacer and a wave washer on the axle shaft followed by wheel assembly, flat washer and a hex
jam nut. See Figure 8. Tighten securely.
