ASSEMBLY
Assembly Section 2-22
SWIVEL BRACKET MOUNTING
Install the boom swivel bracket onto the boom mounting bracket with the swivel pin. Secure
the pin in place using the capscrews, etc. through the hole in the boss and pin. NOTE: The head
of the capscrew must be toward the front of the tractor.
Install all new swivels and fittings on the swing cylinder with swivel openings facing each
other. Fittings will vary in type and direction depending on your application, refer to your parts
section for more details.
Install bearings in the main frame anchor for the swing cylinder. This may already be done
for you.
Install the swing cylinder between the boom mounting bracket cylinder anchor and the boom
swivel with the pins. Insert roll pins through the top and the bottom hole in the pins.
Now the hoses can be attached from the control valve to the swing cylinder.
(ASM-C-0015)
PREFORMED TUBE INSTALLATION
Lay booms on floor so the side with the nuts welded on is up. If mounting a ditcher head,
only the main boom tube installation is required. Locate all tube clamps and install them loosely
in the welded nuts on the left side of the booms.
Arrange the tubes and hoses as outlined in the parts section diagram. Install the smaller tube
closest to the boom arm, being careful not to pinch the tubes. Place the large tubes outside of
the small tubes. Snug all clamp bolts, but do not tighten. Check all tubes for correct alignment
and that none are pinched or bent. The clamp bolts can now be tightened.
(ASM-C-0016)
MAIN BOOM INSTALLATION
Install the boom swivel into the main frame as shown in the parts section using a hoist. Line up holes
in swivel and main frame for large swivel pin and insert pin. Secure with hardware as shown.
Attach the inner end of the main boom to the swivel bracket with the cylinder anchors positioned
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 main boom cylinder to the swivel with the cylinder pin and roll pins shown in
the Parts Section.
Install the travel lock on the rod end of the main boom cylinder. This should be facing the butt end of
the cylinder after installation.
Install the fittings and hoses to the main boom cylinder per Parts Section.

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.
