2. SET UP & OPERATION
Safety: Ensure tractor and machine is stopped & keys out of ignion before set-up/maintenance.
Safety: Check for underground wiring, pipes or other obstrucons before operang.
You will need:
Your tractor, tractor top link arm (adjustable), linkage pins and some elbow grease!
Aaching The Machine
Start by nding a at piece of ground. Lower the three point linkage on your tractor to its lowest
posion and aach the machine to the tractor using the three point linkage pins and linch pins.
Adjust the tractor’s lower linkage arms up or down to ensure the machine sits level on the ground at
both ends. Extend or retract the tractor’s top linkage arm to get the box level so the front to back are
also both touching the ground.
Pre-Use Checklist
Before starng the machine, always check and adjust the following;
Tine height is set [Secon 3]. Blades are in good condion [Secon 4].
Check work site for underground obstrucons. Tightness of all bolts, nuts and screws. Ensure all safety
guards are in place.
General Operang Instrucons
When grading or levelling the working speed of the machine should always be at a walking pace
(approx. 2 to 4 mph).
With the ripper nes raised all the way up and tractor in moon, simply lower the box scraper blade to
ground level and it will start shaving the soil surface. Any dirt or aggregate material should accumulate
in the box. Move the material by dragging it and then raising the scraper to deposit your load.
Alternavely, set the scraper to shave o high spots on uneven ground and the accumulated material
will ow out under the blade in low spots. It can also be used for backlling, simply lower your scraper
and back the rear facing grader blade into the pile of dirt you are using for backll.
Occasionally the ground or surface material will be very hard and will require ripping to loosen the soil
to allow the scraper blade to be eecve. If more aggressive ripping acon is desired, lower the nes
by 2” increments. If less aggressive ripping acon is desired, raise all of the nes.
Geng the right set up requires experimentaon and experience in your given condions. Box
scrapers generally perform beer in dry to slightly damp soil condions.

3. ADJUSTING RIPPER TINES
Safety: Ensure tractor and machine is stopped & keys out of ignion before set-up/maintenance.
Safety: Always take care when handling and changing sharp blades.
Occasionally the ground or surface material will be very hard and will require ripping to loosen the soil
to allow the scraper blade to be eecve. If more aggressive ripping acon is desired, lower the nes
by 2” increments. If less aggressive ripping acon is desired, raise all of the nes.
Suciently li the machine so that the blades and nes can be accessed easily. Always support the
machine on rigid supports and ensure it is stable before carrying out any work.
Ripper Tine Height Adjustment
1. Remove the R clip (1) and remove the curved pin (2)
2. Move the ripper nes (3) up or down to the desired height and align the holes on the ne
and body
3. Then re-insert pin (2) in the slot and replace R clip (1)
4. Repeat the process for the remaining nes so they are all level

support the machine on rigid supports and ensure it is stable before carrying out any work.
Changing Grader Blades
1. Remove all bolts 1
2. Flip over the worn blade or replace with a new blade aligning with holes on the body
3. Replace all bolts

5. MAINTENANCE
Safety: Ensure tractor and machine is stopped & keys out of ignion before set-up/maintenance.
Safety: Always take care when handling and changing sharp blades.
General Maintenance Tasks
Bolts: Aer using your scraper for several hours, check all bolts to be sure they are ght.
Blades: Check blade ps before use and replace when broken or worn.
Scraper: Check the condion of the scraper blades. The front and rear blades have two cung edges
and are reversible. Replace the cung blades when both edges are worn out.
Cleaning: Ensure the machine is cleaned of mud and grass. Remove debris is from any moving parts.
Paintwork: Re-coat any damaged paintwork to prevent corrosion.
Storage: Store the machine in a dry, level area and ensure it is stable and unable to move or overturn.
At the end of the working season or when your box scraper will not be used for long period, it is good
pracce to clean o any dirt or grease that may have accumulated on the scraper and any of the
moving parts.
Inspect scraper for loose, damaged or worn parts and adjust or replace if needed.
*The periods recommended are based on normal operang condions. Severe or unusual condions
may require more frequent maintenance.
