READ THE COMPLETE ASSEMBLY INSTRUCTIONS BEFORE
STARTING THE ASSEMBLY.
You should have the following parts with the complete floatation kit:
- one rear wheel support assembly with receiver assemby and clamping flat attached
- one caster support assembly with receiver assembly and clamping flat attached
- two cross brace tube assemblies
You should have the following parts if you currently have an electric lift kit:
- one rear wheel support assembly with receiver assemby and clamping flat attached
- one caster support assembly with receiver assembly and clamping flat attached
Before doing any installations or adjustments shut off mower engine.
A. CARRIER ARM PREPARATION (Refer to Figure 1)
1. For models that already have mounting holes present, section A. can be omitted. For models
with the electric lift kit installed, refer to section E. For models without mounting holes, locate
the hole positioning according to figure 1. The measurement should be taken from the front
edge of the carrier arm and extend to the center of each hole. The front hole should be at a
distance of 10-3/4” from the front edge of the carrier arm and the rear hole should be 65-9/16”
from the front edge of the carrier arm. Hole positioning will need to be located on both the left
and right carrier arms.
2. Using a 17/32” (.531”) drill bit, drill all four holes. Take care to drill straight through the carrier
arms.
Note:
Hole misalignment from top to bottom may cause difficulty during assembly.

B. INSTALL CROSS BRACE TUBES (Refer to Figure 2)
1. Remove the 1/2” x 5-1/2” bolts and lock nuts from the ends of both of the cross brace tubes
and save for step 2.
2. Align the cross brace tubes over the holes that were drilled in section A. For models that
already have mounting holes present, use the two holes that are closest to the center of the
carrier arm. Place the 1/2” x 5-1/2” bolts through the carrier arm from the bottom up. Place
the lock nut on the bolt from the top side. Snug the lock nut up but do not fully tighten. The
cross brace tube needs to pivot slightly during height adjustment.
C. INSTALL RECEIVER ASSEMBLIES AND CLAMPING FLATS (Refer to Figure 2)
1. Remove the wire lock pin from both of the receiver assemblies and save for section D.
2. Remove the caster support assembly and rear wheel support assembly from the receiver
assemblies.
3. Remove the four 1/2” x 3-1/2” bolts, nuts and lock washers from each receiver assembly and
clamping flat.
4. Position the receiver assemblies in the desired location on the cross brace tube. Insert the
four 1/2” x 3-1/2” bolts from the bottom up and place the clamping flat on the top. Secure the
bolts with the lock washer and the nut. Tighten down appropriately to prevent unwanted
loosening.
Note:
If the floatation kit is positioned to the same side as the tongue there may be
interference. It may be necessary to relocate the tongue and hitch pivot to the
opposite side.
D. INSTALL CASTER SUPPORT ASSY. AND REAR WHEEL SUPPORT ASSY.
(Refer to Figure 2)
1. Insert the caster support assembly into the front receiver assembly and install the wire lock pin.
2. Insert the rear wheel support assembly into the rear receiver assembly and install the wire lock
pin.
E. INSTALLION OF FLOTATION KIT PARTS ON ELECTRIC LIFT KIT MODELS
(Refer to Figure 3)
1. Remove the wire lock pin from both of the receiver assemblies and save for step 5 and 6.
2. Remove the caster support assembly and rear wheel support assembly from the receiver
assemblies.
3. Remove the four 1/2” x 3-1/2” bolts, nuts and lock washers from each receiver assembly and
clamping flat.
4. Position the receiver assemblies in the desired location on the upper actuator mount. Insert
the four 1/2” x 3-1/2” bolts from the bottom up and place the clamping flat on the top. Secure
the bolts with the lock washer and the nut. Tighten down appropriately to prevent unwanted
loosening.
