Rear Location
To adjust the height of the center boom at the rear
position:
1.
Park the self-propelled windrower in a flat,
level area. Lower the rear center boom to the
ground by depressing the rear boom switch on
the control pedestal in the cab.
2.
With a tape measure, measure the height of
the nozzle tip from the ground at outside edge
of the center boom.
3.
Remove the bolt fastening the chain to the
center boom.
4.
Adjust the length of the chain by securing the
bolt to the center boom through a different link
in the chain. Adjust the height of the center
boom to be 12 to 16 inches (30 to 40 cm) off
the ground. Adjusting the rear boom to this
height will provide suspension for the boom
when spraying at 20" (50 cm) from the ground.
To completely remove the rear center boom from
the self-propelled windrower when using the
windrower for other MacDon header applications:
1.
Remove the hair pin and clevis pin securing
the chains to the rear center boom linkage.
2.
Disconnect spray system hose located on the
right side deck of the self-propelled. Ensure
the hose is clear of the ground to prevent
contamination.
3.
Remove the hair pins and clevis pins that
secure the support tubes to the walking beam
for the rear caster tires on the self-propelled
windrower.
