Mounting the Undercarriage

Assembly

Make certain the correct upper drive belt (754-0498) is installed on the undercarriage assembly. If the appropri- ate belt is not installed, replace it with the correct belt prior to proceeding with mounting the undercarriage.

IMPORTANT: Make certain that the flat side of the belt is facing outward as it sits against both the idler pulley and spindle pulley. This allows the “V” side of the belt to ride snugly in both pulleys.

1.The undercarriage assembly should be in position beneath the tractor, since you already connected the PTO cable in the previous steps.

2.Remove the nut from the rear undercarriage mount- ing stud located on the tractors frame rail on the right side of the tractor. See Figure 21.

3.Lift the undercarriage assembly up, inserting the weld pins on the assembly up through the aligning holes found along the tractor’s frame rails. Fasten with hairpin clips and flat washers removed earlier. See B in Figure 22.

The rear hole on the right side will fit over the stud already installed on your tractor. Fasten with the wing nut (included with your hardware pack) and flat washer removed earlier. See A in Figure 22.

4.Connect the extension spring found in your units loose parts that was mentioned earlier. This spring connects to the idler bracket on the undercarriage assemble and the hole on the rear right-hand snow thrower mounting bracket. See Figure 23.

5.Attach the lower auger drive belt by routing it around and through the pulley system as seen in Figure 23.

NOTE: Proper belt routing diagrams can be found on page 18-19 of this manual.

WARNING

Before installing attachment, place tractor on a firm and level surface. Place the PTO in the disengaged (OFF) position, set the parking brake, shut engine off and remove key to prevent unintended starting.

IMPORTANT:

Make certain that the flat side of the belt is facing outward as it sits against both the idler pulley and spindle pulley. This allows the “V” side of the belt to ride snugly in both pulleys.
