CAUTION
Be sure you are not working over any underground wiring,
pipes, or other obstructions. If there is any doubt, call your
local utility services so that they may mark the location of any
under ground utilities in the area. Be sure to ask how close you
can work to the marks or flags they positioned.
!
CAUTION
Make sure all safety labels are in their proper location and in
good condition before operation. Follow all directions on the
safety labels.
Transporting
!
WARNING
When traveling on public roads, use accessory lights, SMV
sign, clean reflectors, and other adequate devices to warn
operators in other vehicles of your presence. Always comply
with all federal, state, and local laws.
1. Be sure to reduce tractor ground speed when
turning, and leave enough clearance so the
Retractable Box Scraper does not contact obstacles
such as buildings, trees, or fences.
2. Select a safe ground travel speed when transporting
from one area to another.
3. When traveling on roadways, transport in such a way
that faster moving vehicles may pass you safely.
4. When traveling over rough or hilly terrain, shift tractor
to a lower gear.
Basic Operation
Refer to Figure 2-1:
Raise shank bar to the upper position by extending
hydraulic cylinder. Retract cylinder to lower shank bar to
working position. Shank tube lock (#1) should be fully
engaged when shank bar is lowered to avoid pressure to
hydraulic cylinder and linkage.

IMPORTANT: Be sure to check shank tube lock (#1)
to make certain it has fully engaged onto the frame
locking lug as shown in Figure 2-1 before working
the soil.

General Operating Instructions
Once you have familiarized yourself with the Operator’s
Manual, completed the operations checklist, and
properly attached your Land Pride 35 Series Box
Scraper to your tractor, you are now almost ready to
begin work. Hopefully you have checked out your work
site for any buried utility cables, pipelines, or other
obstacles that you would not want to damage or
encounter. If you intend to meet or develop actual grade
elevation specifications, your surveyors’ grade stakes
should be in place at this time.
A Box Scrapers primary purpose is grading and leveling.
This function is best done at an approximate 2 to 4 mph
ground speed. Simply lower the Box Scraper to the
ground and proceed forward. The grader blade should
immediately begin shaving the soil surface and dirt or
aggregate material should begin accumulating in the
box. You can transfer this material by dragging it to a
nearby location and then slowly raising the Box Scraper
to deposit your load. High-back models will have the
capacity to transfer more material. You can also achieve
a more uniform distribution and leveling of scraped
material by setting the Box Scraper to shave off high
spots allowing accumulated material to flow out under
the grader moldboard blade in the low spots.
Occasionally the ground or surface material will be very
hard and will require ripping to loosen the soil profile.
This will make Box Scraper blade operations more
effective. When aggressive ripping action is desired,
hydraulically rotate the whole compliment of shanks until
they are locked into position and protruding below the
side panels of the Box Scraper. The more you adjust the
shanks downward in 2" increments the more aggressive
they will become. If less aggressive ripping action is
desired, manually adjust or reposition the shanks
upward. When performing ripping operations, the
simultaneous scraping and leveling operations should
become much easier and more productive.
The hinged rear gate of your 35 series Box Scraper can
be locked in place for scraping or unlocked to allow a
simultaneous floating and leveling action of accumulated
material flowing out of the box. Achieving the desired
effect will require a little experimentation in your given
conditions. Box Scrapers generally perform better in dry
to slightly damp soil conditions. the scraper can be used
for backfilling applications with the rear hinged gate
locked or unlocked. Simply make sure your ripping
shanks are locked in the raised position and back the
rear facing grader blade into the pile of dirt you are using
for backfill. Continue backfilling and pushing operations
until you have successfully completed the task.
With a little practice, you should become a very good
operator and consistently achieve the desired results you
expect with your Land Pride Retractable Box Scraper.
