The SBX Series Box Scrapers will fit most Category I
Tractors equipped with a standard 3-point hitch. The BX-
48 box scraper will fit Cat. 0 3-point hitch tractors when
equipped with Cat. 0/I pull pins.
If tractor has Cat. 0 (20”) lift arm spacing and Cat. I lift
arm balls (7/8” dia.), then install the pins to the inside
(SBX-4 model only).
Check the tractor’s 3-point hydraulic lift system. It
should operate up and down smoothly and hold its
position when set. Refer to your tractor owner’s manual
or dealer for any adjustments necessary to put the 3-
point hydraulic lift system in good working order. (I&T
shop manuals will list most specifications and adjustment
instructions - available from most farm equipment
dealers.)
Tractor should be equipped with stabilizer bars,
adjustable sway chains, or sway blocks to keep the
implement from swinging side to side.
Smaller size tractors may need front counter weights to
counter-balance the weight of the implement.
It is recommended that the tractor be equipped with a
Rollover Protection System (ROPS) and a seat belt that
is used.
Be sure your tractor is in good condition. Read all
the safety precautions and make sure all tractor oper-
ators are familiar with the safety rules of operation.
C A U T I O N !
When using the box scraper in a reverse position
use extra care - DO NOT RAM BOX SCRAPER into
dirt piles! Tractor lift arms and the box scraper are
not built to take high impact loads in this position.
RAMMING backwards can also dislodge operator
from seat and/or tractor controls, resulting in
possible serious injury or death.

KEEP FEET CLEAR
WHEN LOWERING SHANKS!
C A U T I O N !
1. Attach the upper 3-point a-frame members, to the
lower 3-point hitch lugs as shown on page 5, with
hardware as indicated. DO NOT tighten hardware.
Align the a-frame top link and lower hitch holes in
order to allow your hitch pins to pass through them.
A-frame should be positioned square to the box
scraper frame when tightening hardware.
2. Before inserting shanks, attach box scraper to tractor
3-point hitch using top 3-point hitch pin and linch pins
furnished by customer, or raise up front of box
scraper and support with blocks.
SHANK SETTING & ADJUSTMENTS
Remove shanks from shipping position and insert into
shank tube from the bottom side with tips pointing
towards the tractor. Position shank to the desired depth
and secure with shank lock pin (#19) and hair pin cotter
(#20).
Shank settings from bottom of end plate to tip of shanks
are as follows:
PITCH ADJUSTMENT
Leveling the box scraper or increasing the pitch of the
cutting blade is accomplished by adjusting the top link of
the tractor.
STORAGE
At the end of the working season or when the box
scraper will not be used for a long period, it is good
practice to clean off any dirt or grease that may have
accumulated on the scraper and any of the moving parts.
Inspect the scraper for loose, damaged or worn parts
and adjust or replace if needed.
Repaint parts where paint is worn or scratched to
prevent rust.
Store box scraper in a clean, dry place.

This SAFETY SIGN is
located on the frame of
your box scraper.
Obey ALL Safety
Warnings.
NOTE:
If Safety Sign is missing
or damaged, replace
immediately.
Keep alert and watch the front as well as the rear when working with the box scraper.
When maneuvering close to buildings or passing through narrow areas, be sure to allow sufficient clearance
for the box scraper.
Do not operate close to ditches or creeks. Slow down when operating over rough ground.
Always be sure the box scraper is in the fully raised position when in transport.
When removing, changing the shanks, be sure that your feet are never under the box scraper.
Use extreme caution when backfilling deep holes or trenches.
Be careful to avoid catching the box scraper on stumps or other immovable objects.
Use care when working on slopes.
Avoid excessive speed during operation.
Make adjustments only when the box scraper is attached to the tractor.
When using the box scraper in a reverse position, use extra care. Do not ram box scraper into piles of dirt.
Tractor lift arms and the box scraper are not built to take high impact loads in this position. Ramming back-
wards can also dislodge operator from seat and/or tractor controls, resulting in possible serious injury or death.
Always ease the tractor into the load. It may be necessary to reposition and take less “bite” on the material to
move it safely.
Watch for and avoid hidden obstructions, i.e., buried pipes, rocks, concrete piers, uneven concrete slabs,
stumps, etc., when operating.
