John Deere GM2109 Lawn Mower User Manual


 
CAUTION: Always ensure that the tractor tire pressure is correct according to the
tractor operator’s manual.
DANGER: Failure to ensure a secure coupling of the implement to the tractor can
cause injury and damage to the implement or tractor.
To attach the mower to the tractor do the following:
1. Back the tractor up to the mower in order to slip the tractor hitch arms over the hitch
pins welded to the mower hitch arms. Turn off the tractor engine. Secure them in
place with the lynch pins.
2. Adjust the tractor sway blocks or chains to remove all side movement.
3. Attach the top link. Adjust tractor top link to allow the mower to follow the ground
contour and yet remain as level as possible when raised to transport position.
4. Install the shielded driveline to the tractor by first lining up the splines and
depressing the snap pin. Push the yoke onto the PTO shaft as far as it will go.
Release the pin and pull back slowly until the pin clicks in place. Repeat this
operation on the implement end.
5. Ensure that the driveline has at least 2” from bottoming out in its shortest working
position and has the minimum 6” overlap in its longest working position. Refer to
Section 4.06
5
of this manual, if it is determined that the driveline is too long and
needs to be shortened. Contact your local dealer if it is determined that the driveline
is too short for your tractor.
6. Attach the driveline chains to the tractor and to the mower to keep the driveline
protection from turning. The chains should not be too tight.
3.06 - Start Up
DANGER: The mower must always be lowered to the ground before starting
tractor engine or engaging PTO lever.
Lower mower to the ground with the tractor rock shaft control lever. With the engine
idling, slowly engage the PTO drive. Move the throttle lever until the PTO speed
indicated on the mower is obtained.
The mower is set for a PTO speed of 540 rpm.
Shift the transmission to a slow speed gear and start forward, increase the ground
speed by shifting upward until the desired speed is obtained. Do not mow in reverse
unless absolutely necessary and only after careful observation of the area behind the
mower.
