ASSEMBLY INSTRUCTIONS
Read the complete assembly instructions before starting the assembly.
You should have:
- one mower deck assembly
- two carrier arm assemblies
- two rear tire assemblies
- one ATV tongue assembly
A. ASSEMBLY OF MOWER WHEELS
1. Set the mower deck assembly on wood blocks so that it is suspended off the ground.
Note: The operator controls are on the front of the deck. (Left and right are determined by
looking in the direction of travel or by standing at the rear of the deck assembly looking
forward.)
2. Install the rear tire assemblies on the carrier arm assemblies. Remove the hex nut and lock
washer from the rear tire assembly and install the 5/8”x7-1/2” tire axle bolt through the hole in
the carrier arm assembly. See figure 1. Secure assembly with the lock washer and hex nut
provided on the rear tire assembly. The rear tires should be offset to the outside of the deck
assembly on both sides. See figure 2.
3. Install the two carrier arm assemblies in the pivot arms, which are located on the mower deck
assembly. Place the assembly so that the castered tires are on the front and the fixed tires are
on the back. See figure 2. Secure with 1/2" x 3-1/2" hex head bolts and lock nuts provided on
the pivot arms. Mount the height adjust screw on the deck assembly in the hole provided.
Secure with the 1/2”x1” hex head bolt and lock nut provided on the height adjust screw.
Note: Tighten 1/2” x 3-1/2” and 1/2” x 1” hex head bolts until just snug. This area needs to
pivot when adjusting the height. Under tightening can result in excessive wear and
flexing. Over tightening will make adjusting the cutting height very difficult.
B. INSTALLATION OF TONGUE ASSEMBLY
1. The tongue can be installed either on the left or right caster assembly depending on how the
tow-behind mower will be towed. See figure 2. Secure the hitch pivot on the chosen caster
assembly with the 1/2” x 3-1/2” hex head bolt, lock washer, and nut provided.
2. Install the tongue into the hitch pivot and secure by placing the provided 5/16” wire lock pins on
each side of the hitch pivot.
Note: To help prevent any unwanted pin removal caused by oncoming debris install the 5/16”
wire lock pins with the wire lock section back from the direction of travel. See Figure 3.
