RAKE ASSEMBLY INSTRUCTIONS
ASSEMBLY
1. Remove rake and attaching parts from shipping crate.
2. See Page 12 and 14, Figures 1 & 2 for parts identification and location. Attach the hitch to the rake
frame with 1 X 3-1/2 bolt and nylon locknut as shown on Page 8, Photo 5.
3. Attach the top link to the rake frame with a 5/8 X 6 bolt, long spacer, lockwasher and nut.
4. Attach the rod end of the cylinder to the rake frame with a 5/8 X 2-1/2 bolt, lockwasher and nut.
5. Attach the rake to the tractor.
6. Leveling adjustment:
A. Place tractor with rake installed on a level floor.
B. Place the rake in straight position.
C. With caster wheels in the rear position, add or remove spacers until the rake and wheels will
contact the floor. Typical setting is one spacer at the bottom and the remaining 3 spacers at
the top.
D. Angle rake to the extreme right position. Adjust top link to obtain equal rake surface contact in
this position. Angle to the extreme left postion and check again. The ideal setting is to have
the rake touch the floor equally in all postions. This is the setting you would likely use for
spreading topsoil or gravel.
E. For more or less working depth, minor adjustment of the top link may be needed.
7. Check and tighten all bolts. Grease the center pivot ball and caster wheels.

RAKE OPERATION
1. The power angle allows the operator many choices of rake position. The rake may be power angled
straight ahead, to the right or left , or any position in between.
2. Gauge wheels are adjustable by moving 1/2" spacers to obtain correct working depth for various
surface conditions. The wheels may be mounted to the front or to the rear as the task requires.
3. After making the initial setting for the working depth by moving the spacers, fine tune the setting by
adjusting the top link. This is important when using the rake to spread topsoil and/or gravel.
4. Operate only with front lift in the “FLOAT” position. Do not use down pressure.
5. Always rake in forward direction. Raise the rake when backing.
6. Use the Model BD260 power angle blade where large amounts of material need to be leveled.
Remove large rocks before raking. Do not use this Terra Rake as a bulldozer. It is designed for light
duty soil finishing and conditioning.
