SECTION 1 - Trailer Assembly
1.1 AXLE STUB ASSEMBLY
1.1.1 Axle Stub Assembly - Non-Suspension Trailer
CAUTION! To prevent personal injury when assembling the sprayer, raise the trailer and block in place
before inserting the axle stubs. Be sure the trailer is stable before any work begins. Never
rely on a jack or hydraulic devise to support a raised implement.
The sprayer must always be connected to a tractor when the booms are in field position.
CAUTION! Always position the wheel track at the widest possible spacing which will increase the
stability of the sprayer. Only use the narrow settings when absolutely necessary. Use
extreme caution when turning corners or on hill sides when the tracking is set in the narrow
spacing. The centre of gravity of the sprayer is high when the tank is full.
Two lengths of Axle Stubs are available for the sprayer. The short stub has a wheel spacing of 72” to 120” and the
long stub has a spacing of 88” to 152”
NOTE: If the sprayer has been shipped with the Axle Stubs installed, the stub spacing MUST be adjusted. See
the warning on page 3.
1. Raise the trailer so the bottom of the axle housing is at least 43” off the ground and block in place.
2. Loosely assemble the Small Clamps to both ends of theAxle Housing using four 3/4”x 10” bolts and lock nuts,
where shown in Fig. 1.1. Just start the nuts on the bolts at this time.

3. Mount the Large Clamp Plates to the bottom of the
Axle Housing using four 3/4”x 6” bolts and lock nuts
on the outside of the housing and four 3/4”x 11”
bolts and the Axle Bolt Plate on the inside of the
housing. Just start the bolts into the nuts at this time.
See Fig. 1.1.
4. Slide the Axle Stubs into axle housing. Make sure
the stub on the left side of the frame is in the back
portion of the housing and the stub in the right side is
in the front. Always position the wheels at the widest
possible track spacing to reduce the possibility of
tipping the sprayer.
Note: The hubs are offset on the stubs
to keep the trailer wheels inline. Make
sure the offset on the right stub is towards
the back of the trailer and the offset on
the left stub is towards the front of the
trailer.
5. Adjust the stubs to the desired
wheel track and clamp in place.
Example: If the wheel tracking is to
be set at 88”, adjust the stubs so
the outside of the hub flange is 44”
from the centreline of the trailer
when installing single wheels. The
duals come with 11” or 15” offsets.
Add the offset to the stub dimension
to get the proper inner dual tracking
width. To get 44” on the inner dual,
the stub must be at 55” or 59”.
IMPORTANT: Make sure the stub is
not extended past the inner clamp in the
axle housing. See Fig. 1.2.
Note: Two stop bolts have been placed
in the axle housing to restrict the narrow tracking capability of the axle stubs. See Fig. 1.3. Going beyond these
bolts should only be done if absolutely necessary.
If the narrow track spacing must be used, you MUST slow down and/or reduce the water level in the tank to
compensate for the narrow track width. Remember, the centre of gravity of this sprayer is high when the tank is
full.
Fig. 1.4 shows the centre to centre tracking widths when the stubs are pushed against the stop bolts.
