ASSEMBLY GUIDE
The upper driveline in Figure 36 has a torque limiting slip clutch installed in order to protect the tractor and
mower in the event of an overload condition. The side having the clutch is connected to the gearbox input.
The lower driveline has a one-way clutch sometimes called an over-run clutch to keep the stored rotational
energy in the rotating drums from back-driving the tractor. Install the clutch end to the drum assembly and the
other plain end onto the gearbox output spline.
Depending on your tractor, it may be necessary to cut the tractor PTO (the top one in the photo) if it is too long.
Refer to the owner's manual supplied with the driveline for procedure on how to cut the driveline to the correct
length if it is too long. Leaving a driveline too long can damage the tractor, driveline and the mower. The
manual supplied with the driveline details all maintenance and lubrication procedures. Please keep it for
reference, and read it before using the equipment. Tractor Tools Direct also has a downloadable guide and a
video at
www.tractortoolsdirect.com
that shows the basic steps to cut a driveline PTO. We recommend,
however, that you follow the manufacturers published literature for specific clearance values and minimum
overlap measurements for safe operation of your equipment.
Lubrication
Verify the level of the oil in the 90 degree gearbox on the three point hitch. The level should be half way up and
filled to the level of the plug on the side. Use an EP (extreme pressure) rated gear oil that is close to 90 weight,
such as 80W-90. Although units are shipped with oil, it is always a good idea to check them one last time before
first use.
The fill and check point for the drum unit gearbox is near the pivot pin. Check the oil using a clean stick, such
as a straw or something similar and insert it into the fill hole, touching the bottom of the gearbox with it. The oil
should coat the bottom 1 3/4" to 2" of the stick when properly filled. Do not overfill. See the owner's manual
specific to your mower model for the required volume. Use an EP (extreme pressure) rated gear oil that is close
to 90 weight, such as 80W-90. The mower comes filled with oil when new, but the level should be verified
before every use. Check when cool and on level ground.
