BOX SCRAPER HYDRAULIC CONNECTION
READ AND UNDERSTAND ALL SAFETY STATEMENTS
Read all safety decals and safety statements in all manuals before beginning any Snow
Blower hydraulic connection. Know and obey all OSHA regulations, local laws, and other
professional guidelines for your operation. Know and follow good work practices when
assembling, maintaining, repairing, mounting, removing, or operating this equipment.
1. Remove all the protective plastic caps from the hose ends.
2. Make the connection to your prime mover using the appropriate method below for your prime mover:
• If your prime mover has male or female threads for connecting the hydraulic hoses to the auxiliary
hydraulic lines, make certain that the threads, as well as the inside of the fittings and hoses, are
clean, then secure the hoses to the fittings using the torque specified in your prime mover’s
operator’s manual.
• If your prime mover has quick-couplers for connecting the hydraulic hoses to the auxiliary hydraulic
lines, you may need to purchase the proper quick-coupler fittings that you must install on the free
ends of the two hoses. In most cases, the owner’s manual for your prime mover will describe the
exact type of fitting that is needed for your hydraulic coupling system, but in no case should any
fitting have an allowable operating pressure of less than 4,000 psi. Once all the quick-coupler
fittings are properly installed, then the hoses can be coupled to the prime mover’s hydraulic valve
body or auxiliary hydraulic lines as per the instructions found in your prime mover’s operator’s
manual.
3. Carefully raise the 3-point hitch to check hose clearances and to check for any interference. Operate
the hydraulic cylinder(s) on this product to make the same checks.
4. Cycle the hydraulic cylinder(s) on this product several times from fully retracted to fully extended
until all air has been completely removed from the cylinder(s).
WARNING! Do not lock the auxiliary hydraulics of your prime mover in the "ON" position.
Failure to obey this warning could result in death or serious injury.
NOTICE: When shipped, the hydraulic cylinder(s) on this product contained air or an air-fluid mixture.
There are orifices beneath the port(s) in the hydraulic cylinder barrel(s) that will restrict the
exit of that air. Failure to remove all the air from the hydraulic cylinder(s) can cause
uneven, jerky cylinder movement when the hydraulic controls are being operated and
unwanted cylinder movement when the controls are not being operated.

BOX SCRAPER SETUP
READ AND UNDERSTAND ALL SAFETY STATEMENTS
Read all safety decals and safety statements in all manuals before beginning any Snow
Blower setup. Know and obey all OSHA regulations, local laws, and other professional
guidelines for your operation. Know and follow good work practices when assembling,
maintaining, repairing, mounting, removing, or operating this equipment.
EXCAVATING, GRADING, AND BACKFILLING
Park your prime mover on a level surface with this product properly attached.
Place your prime mover's transmission in "Park" and engage the parking brake.
Lower this product onto the level surface.
Make sure that the hydraulic cylinder is fully extended so that the ripper shanks are in the fully raised
position.
Shut off your prime mover's engine, remove the starter key, wait for all moving parts to come to a
stop, and relieve all pressure in the hydraulic lines.
Check to see that the cutting edges of this product are parallel to the level surface. If they are not
parallel, make the edges and the level surface parallel by following the instructions for adjustment of
the 3-point hitch as found in the operator's manual(s) for your prime mover and 3-point hitch.
Check to see that the bases of the main frame end plates are parallel to the level surface. If they are
not parallel, make the bases and the level surface parallel by adjusting the 3-point hitch's top link as
described in the operator's manual(s) for the prime mover and 3-point hitch.
SCARIFYING
Perform steps 1 through 6 above.
Check to see that the bases of the main frame end plates are leaning forward approximately 15
degrees relative to the level surface. If this is not the case, adjust the 3-point hitch's top link as
described in the operator's manual(s) for your prime mover and 3-point hitch. Leaning this product
forward 15 degrees will lift the cutting edges up a few inches off the level surface and will result
in the straight upper portion of the ripper shanks being perpendicular (90 degrees) to the ground
surface during operation.
Verify that the ripper shanks are set in the proper slot for performing the desired work. When the
front edges of the main frame end plates are flush with the ground level, then:
• positioning the ripper shanks in the lower slot will produce a 3-3/4" deep cut and
• positioning the ripper shanks in the upper slot will produce a 6-1/4" deep cut.
See RIPPER SHANK ADJUSTMENT AND REPLACEMENT in the Service section of this manual for
instructions on how to reposition the ripper shanks.
IMPORTANT Operating this product with the ripper shanks only partially extended into the ground
CAN result in damage to this product and
WILL void all FFC warranties.
4. Restart your prime mover and raise the 3-point hitch. Completely retract the hydraulic cylinder to
extend the ripper shanks to their lowest and locked position. Failure to lower the ripper shanks
until the locking mechanism engages will result in excessive hydraulic cylinder strain and could
cause permanent hydraulic cylinder damage.

BOX SCRAPER OPERATION
READ AND UNDERSTAND ALL SAFETY STATEMENTS
Read all safety decals and safety statements in all manuals prior to operating or
working on this equipment. Know and obey all OSHA regulations, local laws,
and other professional guidelines for your operation. Know and follow good work
practices when assembling, maintaining, repairing, mounting, removing, or
operating this equipment.
WARNING! Failure to obey the following procedures could result in death or serious injury.
• Make sure that a qualified individual or firm that specializes in locating
underground utilities has inspected the work area. Do not operate this product
where contact with a utility line of any kind is possible.
• Operate at a very slow ground speed where objects that are not easily moveable
(i.e. stumps, concrete foundations, etc.) may be present.
IMPORTANT Striking objects that are not easily moveable (i.e. stumps, concrete foundations, etc.)
at an excessive ground speed
CAN result in damage to this product and
WILL void all FFC warranties.
IMPORTANT Backing up with any portion of the ripper shanks below the ground surface
CAN result in damage to this product and
WILL void all FFC warranties.
Before beginning any work, have a qualified individual or firm inspect the entire work area for
underground utility lines. The operator should carefully inspect the entire area for stumps, concrete
foundations, large rocks, posts, or any other solid object that would not easily move when struck by
any part of this product. Remember that you Box Scraper is not your bulldozer and is not designed to
remove pavement, uproot trees, etc.
When excavating, grading or back filling, the performance of this product can be fine-tuned by
adjusting the length of the upper arm of your prime mover's 3-point hitch to increase or decrease
digging capabilities. Changes can also be make by varying your prime mover's speed and by
changing control settings for your prime mover's 3-point hitch.
When scarifying, the best method for achieving a desired digging depth is to perform several test
passes. With there being so may variable in operators and ground conditions, this is the best way
to select the correct ripper shank depth slot, the correct speed, and the correct 3-point hitch control
settings.

9. Cut open the existing shank point using a cutting torch. Make sure that the shank is not being
damaged while the shank point is being cut. Remove and properly dispose of the existing shank
point.
10. Slide a new point onto the ripper shank. Make sure that the cutting face of the shank point is
on top of the hooked end of the ripper shank when the ripper shank is held in the normal
scarifying position.
11. Crimp the shank point onto the ripper shank by pressing the sides of the shank point into the
depressions on each side face of the ripper shank tip. Make sure that the deforming force is
applied directly over the ripper shank depressions and that sufficient deformation occurs for the
shank point to be securely attached to the ripper shank.
12. Reinsert the ripper shank into the scarifier tube and seat the ripper shank in the desired slot.
13. Replace the shank block and then the clevis pin. Secure the clevis pin with the rue ring cotter
pin.

and other professional guidelines for your operation. Know and follow good work
practices when assembling, maintaining, repairing, mounting, removing, or
operating this equipment.
REPLACEMENT OF CUTTING EDGES
1. Park your prime mover on a level surface with this product properly attached.
2. Place your prime mover’s transmission in “Park” and engage the parking brake.
3. With the ripper shanks fully lowered and locked into position, lower end plates of the main frame
of this product onto pre-placed blocking as specified below:
WARNING! Failure to obey the following procedures could result in death or
serious injury.
• Do not use blocking made of concrete blocks, logs, buckets, barrels or any other
material that could suddenly collapse or ship positions. Do not use wood or steel
blocking that shows any signs of material decay. Do not use blocking that is
warped, twisted, or tapered.
4. Shut off your prime mover’s engine, remove the starter key, wait for all moving parts to come
to a stop, and relieve all pressure in the hydraulic lines.
5. Make sure that this product is completely stable on the blocking. If the blocking appears to
be unstable or is even of questionable stability, restart your prime mover, raise this product off
the blocking, and move away from the blocking. After the blocking has been repositioned in a
more stable fashion, repeat steps 1 through 5 until a completely stable condition exists.
6. TWO WORKERSARE REQUIRED to remove a cutting edge. From the rear of this product,
reach under the rear cutting edge, loosen and remove the center five nuts, then remove the
corresponding bolts.
7. Loosen the remaining two nuts. While the first worker holds up one end of the cutting edge, the
second worker must remove the nut and bolt from that end so that the first worker can lower that
end of the cutting edge to the surface below. Repeat this process for the remaining bolt.
8. The cutting edge can then be turned end for end and be reinstalled or, if both edges are worn
out, the old cutting edge should be properly discarded. Whether reversing the cutting edge or
installing a new one, replacement of all bolts is recommended. Replacement of all locknuts and
any damaged or worn bolts is required.
9. Reverse the removal process in Step 7 and loosely secure the cutting edge with two bolts: one in
each end hole. Install the other five bolts, then gradually and uniformly tighten all the bolts to
100 ft. lbs. + or - 6.0 ft. lbs., drawing the cutting edge into the proper operating position.
10. If necessary, repeat steps 6 through 9 for the second cutting edge.
