Figure1-8: Installing Hitch Bracket Weldment-Upper and Fittings
Tractor Hook-Up
1. Be certain that tractor draw bar will not interfere. Move draw bar ahead or remove if required. Draw bar should also be
checked for clearance when unit is being raised for the first time.
2. Align lower link arms of tractor to hitch clevises on mower. Insert lower hitch pins into lower ball swivels and attach link
pins.
3. Attach tractor top link to upper floating hitch on mower with pin supplied. Secure with lock pin.
4. Adjust tractor top link in or out to place upper hitch pin vertically above or slightly behind lower hitch pins to allow mower
flotation. The mower should be run with the back 15 degrees lower than the front.
Driveline Installation
1. Slide driveline end with extended safety cone over spline shaft of gearbox and secure with attaching device.
2. Slide driveline over tractor’s spline PTO shaft and secure with locking device of driveline.
3. Driveline should now be moved back and forth to ensure that it is secure on the PTO shaft of the tractor and mower
gearbox.
4. Attach chain from the driveline shield to one of the upper hitch braces to ensure that the shield does not rotate.
5. Should driveline require shortening:
a. Hold the half-shafts next to each other in the shortest working position andmark them.
b. Shorten inner and outer guard tubes equally.
c. Shorten inner and outer sliding profiles by the same length as the guard tubes.
d. Proper overlap is a minimum of one-half the length of each tube, with both tubes being of equallength.
e. Round off all sharp edges and remove burrs. Grease sliding profiles.
CAUTION
Tractor PTO shield and all mower guards must be always in place during operation!
Section 2: Operating Instructions

www.tmgindustrial.com 10 / 18 TOLL FREE: 1-877-761-2819
Transporting
NOTE: Always disengage PTO before raising mower to transport position.
1. When raising the mower to transport position, be sure that driveline does not contact tractor or mower. Adjust and set the
tractor’s 3-point hitch lift height so that the driveline does not contact mower deck in the fully raised position.
2. Be sure to reduce tractor ground speed when turning, leaving enough clearance so that the mower does not contact
obstacles such as buildings, trees or fences.
3. Select a safe ground travel speed when transporting from one area to another. When traveling on roadways, transport in
such a way that faster moving vehicles may pass safely.
4. When traveling over rough or hilly terrain, shift tractor to a lower gear.
CAUTION
When traveling on publicroads, whether at night or during the day, use accessory lights and devices foradequate warning to
operators of other vehicles. Comply with all Federal, State, and local laws.
Mowing Instructions
1. Clear area to be mowed of objects and debris that might be picked up and thrown by the mower blades.
2. Grass is best cut when it is dry. Mowing wet grass can cause plugging resulting in grass clumps behind the mower.
3. Grass should be mowed frequently as shorter clippings deteriorate faster.
4. If mowing extremely tall grass, it is best to raise cutting height and mow the area, then lower cutting height and mow a
second time at the desired height.
Operating Instructions
Proper servicing and adjustments are the key to the long life of any machine. With careful and systematic inspection of the mower,
costly maintenance, time and repair can be avoided.
Before beginning to mow, the following inspection should be performed:
1. Check oil level in gearbox.
2. Check that all plugs in gearbox have been replaced and tightened properly.
3. Be sure all mower knives, bolts and nuts are tight.
4. Be certain all guards and shields are in place and secure.
5. Grease driveline shaft and all other grease fittings.
6. Clear area to be mowed of rocks, branches and other foreign objects.
7. Lower mower to ground. Set tractor throttle at approximately 1/4 open. Engage PTO to start blades rotating.
8. Operate with 540 rpm PTO tractor.
9. At first begin mowing at a slow forward speed and shift up until the desired speed is achieved - maintaining 540 PTO rpm.
10. Mower knives will cut better at a faster blade speed than at reduced throttle.
11. After mowing the first 50 feet, stop and check to see that the mower is adjusted properly.
12. Do not make sharp turns or attempt to back up while mower is on the ground.
13. Do not engage PTO with mower in the fully raised position. Do not engage PTO at full throttle.
Section 3: Adjustments
Leveling the Mower
NOTE: Tractor and mower should be on level ground.
Leveling can be adjusted at the tractor’s 3-point arms and center link.
Cutting Height Adjustment
The machines cutting height depends upon the position of the rear roller.
1. Remove the bolts that fix the roller on both sides.
