INSTALLATION INSTRUCTIONS
1. To mount Box Grader to Super Rake you must remove the rake lift.
2. On all Super Rakes unhook the speed boss arm before removing the rake lift. Completely remove the rod speed
limiter and ball joint from machine. The speed boss does not need to function when using the Box Grader.
3. Position the Box Grader unit at the rear of the trap rake, using the bolts (Ref 6) that held the rake lift on, bolt pivot
brackets (Ref 3 & 5) to the frame. Please note the way the pivot brackets mount to the machine. Trim cuts point
up and tabs bend out.
4. Loosen jam nut on cylinder and turn the cylinder extension (Ref 2) within a 1 /
4
" of the end of the cylinder shaft.
5. Attach the cylinder extension to the Box Grader using the second hole from the end.
6. Turn the trap rake on and test the operation of the cylinder lift several times to make sure the grader blade travels
all the way up. To adjust, turn cylinder extension counterclockwise to lower and clockwise to raise.
7. Springs should be adjusted to a length of 7". Adjust tension to your preference. Tighten to increase trip pressure.
8. To lower break up bar, remove the two clevis pins from the sides of the Box Grader. The break up bar will tilt
forward.
The speed boss is not used with Box Grader. Leave unhooked.
