ASSEMBLY
SWITCHING SIDE MOUNT TO BOOM ARM
If you are changing over from a side mounted mower you must first close the ball
valves and remove the motor hoses from the motor to the solenoid valve. Also
remove and replace any fittings that do not match the ones shown in the parts
section diagram.
Next, disconnect all hoses from the control valve. Remove the pin that connects
the lift cylinder to the mast on the main frame. Remove the inner draft beam pin.
At this point the mower should be loose from the tractor.
Remove the two spool valve and mount the four spool valve for the boom
according the diagram in the parts section. Also refer to the parts section for the
new hoses that will need to be used.
MAIN BOOM INSTALLATION
Attach the inner end of the main boom to the swivel bracket with the cylinder
anchors mounting upward, and at a right angle to the tractor. Secure it with the
horizontal hinge pin. Secure the hinge pin in the boss with capscrews, etc. (see
parts section).
Attach the butt end of the cylinder to the swivel bracket anchor with the special
“bracket head” cylinder pin and roll pin shown in parts section.
Install the fittings and hoses to the main boom cylinder. Install the travelock on
the rod end of the main boom cylinder. These should be facing the butt end of the
cylinder after installation.
GREASELESS BEARINGS ARE DARK GRAY AND SHOULD NEVER BE
GREASED. THE MAIN BOOM CYLINDER AND THE SECONDARY CYLINDER ARE
NOT GREASELESS AND NEED TO BE GREASED.
DECK ATTACHMENT
The pivot assembly is used to attach the head to the secondary boom. Install the
deck pivot cylinder using the pins and hardware, which is illustrated in the common
section.
Connect the fittings and hoses from the pivot cylinder to the small preformed
tubes on the boom arm. Connect the fittings and hoses from the motor to the large
preformed tubes on the boom arm. Connect all remaining hoses from the control
valve to the cylinders and / or preformed tubes on the boom arm. Refer to common
section for diagrams.
