Tailwheel Assembly

(Asm-0050) To assemble the Mower’s TailWheel, follow the procedures listed below.

NOTE: Certain steps may have been performed by the manufacturer before delivery.

1.To attach the tailwheel assembly (2) to the tailwheel beam (1), place a 1-1/2” flat washer (16) on the tailwheel assembly shaft. Insert the shaft, starting at the bottom of the tailwheel beam weldment (end opposite of brace and grease fitting), completely through tailwheel beam weldment hole and bushings. Place another 1-1/2” flat washer (16) onto shaft top. Insert retaining pin (17) through shaft above washer (16) to retain tailwheel assembly (2) to support beam (1).

2.One side at a time, align the bottom holes of the left and right tailwheel beam support brackets (3 and 4) with mower deck rear center holes. Position the brackets with the long sides facing one another. For each support bracket, place a 1/2” flat washer (13) on two 1/2” x 1-1/2” bolts. From inside the deck, insert the bolt ends through the deck and support bracket holes. Install a 1/2” locknut (15) onto each bolt to secure the support bracket to the mower deck. Do not completely tighten bolts and nuts at this time. Repeat procedure for other side bracket.

3.Place tailwheel positioning bracket (5) onto tailwheel beam with bracket holes to the bottom. Side the bracket to opposite end of beam.

4.Place bushing (6) into tailwheel beam (1) end holes. Position tailwheel beam end between set of upright lugs behind mower gearbox. Align holes of lugs, tailwheel beam (1), and bushing (6) and retain with a 5/8” x 5” bolt (8) and 5/8” locknut (12). Do not tighten at this time.

5.Pull tailwheel positioning bracket (5) against support brackets (3 and 4) and align holes of positioning bracket and support bracket at desired tailwheel height. Insert 1/2” x 1-1/2” bolts (7) through each side of support bracket and positioning bracket of selected hole setting. Place 1/2” lockwasher (10) and nut (11) on bolt to secure brackets in position.

NOTE: The rear deck height is set by raising or lowering the tailwheel beam to the desired height. Raise the positioning bracket on the support brackets to reduce the height of cut, lower the positioning bracket to increase the height.

6.Tighten all bolts, lockwashers, and nuts to their recommended torque
