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 front cross brace tube and one rear cross brace tube with height adjust assy.

- one ATV tongue assembly

A. ASSEMBLY OF REAR WHEELS AND CARRIER ARMS

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.

Note: Tighten 1/2” x 3-1/2” 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.

Figure 2: Carrier Arm Installation

B. INSTALLATION OF CROSS BRACE TUBES AND HEIGHT ADJUST ASSY.

For this section, if your mower was purchased with an Electric Lift Kit (Part #003912), refer to

Section C of the Electric Lift Kit Owner’s Manual.

1. Remove the 1/2” x 3” hex head bolts, lock washers and nuts that are located on the top of

each carrier arm (four per carrier arm). The removed hardware will be used in step 2.

2. Install the cross brace tubes on the carrier arms with the 1/2” x 3” hex head bolts, lock washers

and nuts. Only hand tighten the hardware for this step. The support that has the height adjust

assy. fastened to it needs to be placed on the rear location. Orientate the support such that

the height adjust assy. hangs towards the engine. See figure 3.

3. Remove the 1/2” x 1” bolt and lock nut from the lower deck mount. Manually turn the screw

down towards the deck until the screw mounting flat hole lines up with the lower deck mount

hole. After achieving alignment, attach the screw mounting flat with the 1/2” x 1” hex head bolt

and secure the bolt with the provided lock nut. Do not over-tighten. This location must be able

to pivot. See figure 4.

4. Turn the crank on the height adjust assy. and raise the mower to its highest position. At this

time securely tighten the 1/2” x 3” hex head bolts, lock washers and nuts holding the cross

brace tubes in place. This step insures that proper alignment of the carrier arms has been

achieved.

C. INSTALLATION OF TONGUE ASSEMBLY

1. The tongue can be installed either on the left or right carrier arm assembly depending on how

the tow-behind mower will be towed. See figure 5.Secure the hitch pivot on the chosen

carrier arm 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 6.

manual.

WARNING: Do not allow anyone to operate this equipment who has not fully read and

WARNING: Operator should be familiar with all functions of the unit.

A. TONGUE CONFIGURATIONS AND ADJUSTMENTS

WARNING: Shut off the engine and allow the mower blades to come to a complete stop

before adjusting the tongue.

The hitching system is designed so that the rough cut mower can be pulled directly behind a tow

vehicle or offset to the left or right. See Figure 7.

Note: When pulling the mower directly behind, the hitch pivot should be fastened on the right

carrier arm for maximum maneuverability. See Figure 5. When pulling the mower in

the offset position the hitch pivot can be fastened on either the right or left carrier arm.

See Figure 5.
