SETTING UP THE MOWER FOR USE
i.
Attachment to Tractor
Attach the GMF Fieldmaster mower to the tractor’s three-point linkage
a) GMF350 mower is supplied with dual-category lower linkage pins. They are fitted
from the inside of the clevis and secured with a lynch pin on the outside.
b) The top link has two positions, a slot and a hole. For normal mowing, use the slot.
This allows the mower to sit on its rollers and follow the ground contours.
Adjust the top link so that the pin is between 25 and 50mm from the front of the slot
when the mower and the tractor are on level ground. NOTE that the washers
supplied with the top link pin must be fitted on the outside of the slots to prevent the
head of the pin or the lynch pin from getting caught in the slots.
NOTE: For transport, use the hole. This takes the slack out of the linkage and can
prevent serious structural damage caused as the tractor bounces over bumps.
c) If the mower has not previously been attached to the tractor being used, refer to
“Driveshaft Initial Fitting” section.
d) Attach the driveshaft safety chain to prevent the covers rotating. Leave plenty of
slack in the chain so that it is not broken when the mower is raised on the three-point
linkage.
e) Level the tractor’s lower link arms so that both sides of the mower touch the ground
simultaneously as the three-point linkage is lowered.
f) Tension the sway chains or fit stabiliser bars to limit lateral movement.
g) Raise the three-point linkage slowly to check:
-
Mower does not touch tractor tyres.
-
Driveshaft does not touch any part of the tractor or mower.
-
Driveshaft angles do not become excessive (above 35 degrees).
-
Mower gearbox input shaft remains approximately parallel to the tractor PTO
output shaft (within 5 degrees is satisfactory).
-
Driveshaft halves do not separate.
If any of these are not correct it may be necessary to limit the maximum lift on the
tractor lift lever quadrant and/or relocate the top link arm.
