Alamo GR72, GR60 manual Setting Mower Height

OPERATION

7.1 Setting Mower Height

1.Park the tractor and mower on level ground.

2.Using the 3-point hitch control lever, position the front of the mower with the side skids 1” less off the ground than desired cut height. For example, for a 3” cut, position the skids 2” from the ground. Set the 3-point control lever stop at this position to maintain this height when raising and lowering the mower.

3.Shut down the tractor and remove the key.

4.Level the mower deck front to rear by extending or retracting the 3-point top link.

5.Level the mower side to side by manipulating one lower lift arm length. On most tractors, at least one of the lift arms is designed to allow for manipulation of its length. Shortening or extending will allow for deck leveling from side to side.

6.Securely block up the mower at this height.

7.Remove the bolts securing the tailwheel beam positioning bracket to the support brackets and allow the tailwheel to rest at ground level. Align beam and positioning brackets holes with closest set of holes in support brackets and reinstall bolts securing the beam in position. Tighten all bolts and nuts.

8.Extend the tractor’s top 3-point link so that when lifting the mower, the front of the deck will raise 2 to 2½" before the tail wheel leaves the ground. This will allow the mower to follow the contour of uneven terrain.

NOTE: Install optional check chains when there is

aproblem with the hydraulic 3-Point lift maintaining a set height or when a constant pre-adjusted cut height is required. See Check Chains in the Assembly Section for this accessory.
