OPERATION
FX-209 07/19 Operation Section 4-7
© 2019 Alamo Group Inc.
OPERATION
If attaching the mower tongue clevis to a 3-point hitch drawbar supported by the lower lift arms, the attaching
point must be extended past the main bar to allow for turning without binding the clevis and bar. Lift arm
stabilizers must be used with this type of drawbar to prevent the mower from swaying from side to side.
3.7 Power Take Off (PTO)
FX-209 mower is designed to operate at a PTO speed of either 540 RPM and 1000 RPM. Most tractors
operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The tractor PTO operating speed
can be determined by the number of splines on the PTO output shaft. Those operating at 540 RPM will have a
6-spline 1-3/8” diameter shaft and those operating at 1000 RPM will have a 21-spline, 1-3/8” diameter or 20-
spline, 1-3/4” diameter shaft. Refer to the tractor owner’s manual for instructions to change PTO speeds on
models that operate at more than one speed.
If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an over-
running clutch must be used between the PTO output shaft and the driveline of the mower. An authorized
tractor dealer can provide the over-running clutch and its installation if needed.
3.6 Front End Weight
A minimum of 20% total tractor weight must be maintained on the tractor front end at all times. Front end
weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the
front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front
weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005
