hoe. Remove pivot pins (7) from end of bucket link (5)
and dipperstick (1). Attach bucket (3) to bucket link and
dipperstick with pivot pins (7) and secure with bolts (10)

INSTALL HYDRAULIC HOSES
Keep hands and body away from pressurized
lines. Use paper or cardboard, not hands or other
body parts to check for leaks. Wear safety goggles.
Hydraulic fluid under pressure can easily penetrate
skin and will cause serious injury or death.
Make sure that all operating and service person-
nel know that if hydraulic fluid penetrates skin, it
must be surgically removed as soon as possible by
a doctor familiar with this form of injury or gan-
grene, serious injury, or death will result. CON-
TACT A PHYSICIAN IMMEDIATELY IF FLUID
ENTERS SKIN OR EYES. DO NOT DELAY.
Make sure shields and guards are properly
installed and in good condition. Replace if damaged.
Power to the backhoe is supplied directly from the trac-
tor hydraulic system. A hydraulic requirement of 3.5
gallons per minute and 1780 psi is necessary to oper-
ate the backhoe efficiently. 3/8" diameter hoses (SAE
100 R1 with 3000 psi working pressure) should be
used to connect the hydraulic source to the backhoe
valve. These hoses must be long enough to allow ease
of removal or attachment of backhoe. Hoses must
include external shielding to prevent oil from spraying
on operator if hose fails.
Refer to the sub-frame mounting kit manual for specific
installation instructions.
INSTALL BACKHOE BRACKETS
Remove backhoe from pallet and position on level sur-
face. Install backhoe brackets found in the sub-frame
mounting kit.
ATTACH BACKHOE TO TRACTOR
Back tractor as near as possible and center on back-
hoe. Refer to the sub-frame mounting kit manual for
instructions on connecting hydraulic hoses and attach-
ing the backhoe to the tractor.
After cycling backhoe through its operating range, stop
tractor and check the oil level in the tractor transmis-
sion.
