INSTALLATION INSTRUCTIONS
1. Locate the pivot plate. The pivot plate is shipped attached with two U-bolts and is pinned to the pivot arm
with a 1” top link pin.
2. The mount the plate horizontal. The center of the pin should be about 11 ½ inches from the ground and
as close to the rear wheels of the utility vehicle as possible.
3. The pivot plate may be mounted higher or lower than suggested. By mounting the pivot plate higher than
suggested increases how tight the sprayer folds into the transport position. Placing the plate lower
increases the amount of down float for the sprayer.
4. Locating the sprayer closer to the vehicle’s rear wheels increases sprayer float but you must make sure
that there is enough clearance for the sprayer to float up i.e. avoid frame, tank, solenoids or other installed
attachments.
5. The plate may be mounted to the utility vehicle by U-bolting around 2 inch tubing uprights.
6. Adjust the pivot arm position by loosening the two lock bolts and sliding over the tubing of the main lift
frame. Lock the pivot arm into place by tightening the bolts and locking with the jam nut.
7. Attach center actuator. For this step it will help to have someone to hold the main frame level or support
the boom with blocks so the actuator can be pinned easily.
8. Begin by pinning the rod end of the actuator to the center actuator mount plates on the lift frame. Use the
center hole.
NOTE: Make sure there is a spacer on each side of the center actuator shaft otherwise severe damage
could occur to the actuator.
9. Pin the motor end of the actuator to the main frame. Locate the motor above the rod of the actuator for
clearance.
LEVEL SPRAYER
1. When all three booms are in the spray position, adjust the booms to be level with the ground. Loosen the
four nuts holding the center actuator pin plates and adjust position by sliding plates on slot and tighten
securely.
NOTE: Center actuator should be fully retracted while adjusting.
2. If you require more range than sliding the plates can give use the next hole in the plate. If further adjust-
ment is required the right and left plates may be swapped giving further range.
PLUMBING
1. Attach flow meter columns.
2. The center column assembly attaches on the solenoid bar at the rear the vehicle. (The center flow
indicator has the necessary nut and bolt in the backing plate.)
WING FLOW METERS
1. The flow indicator for each wing attaches to the wing lift frame for that wing. On the back of each wing lift
frame will be two ¼” bolts and lock washers to mount the columns with.
2. Attach and route the ¾” hose from the flow monitor to the appropriate sprayer solenoid. Secure hoses
with the plastic quick clamps. Tie the hose in place along the lift frame with the supplied cable ties to
avoid pinching or getting caught during folding.
3. Attach and route ½” hose from flow monitor to spray nozzle. Take care to ensure that each column is
routed to the appropriate spray nozzle.
4. Test folding of all sections of the sprayer for possible problems in the routing of the sprayer hose.
