MOUNTING INSTRUCTIONS FOR SKID
LOADERS
Single point hose attachment
for most loaders.
NOTE: All LOWE® skid-steer trenching attachments are equipped with 37 degree JIC adapters. Attachment hoses should
have 5⁄8 inch (-10) female fittings on the attachment end.
1) Insert loader boom plate into Trencher Mounting Bracket.
2) Secure all locking levers or pins in their proper location.
3) Connect two hydraulic hoses to the Trencher and the Loader’s Auxiliary Hydraulic system. Make sure that hoses
are routed through the hose guide provided. Before they are secured, check to ensure adequate length and
clearance through the trencher’s tilt and lift range.
4) You are now ready for operation.
WARNING:
Carry trencher low to the ground at all times. Failure to do so may result in unstable
operation or injury.
Removing the Trenching Attachment
1) Roll the loader’s tilt arms back and lower lift arms to lay attachment level.
2) Stop the engine, release hydraulic pressure in hoses and disconnect auxiliary hoses.
3) Release locking levers or pins.
4) Start the engine and disengage loader mounting plate from trencher mounting bracket.

NOTE: Based on use in moderate soil conditions and on typical skid loaders that match the specific trenching
attachments, your performance may vary depending upon digging conditions and loader used.
Digging with the Trencher:
Operating a skid steer trencher attachment can be fairly complicated, but it can be made much easier if you follow a
few specific guidelines:
1) Making your initial cut should be done with the trencher boom lying flat against the ground. As the chain is
rotating, begin inserting the nose of the boom into the ground while slowly raising the trencher a few inches off
the ground. Point the nose down gradually.
Once the trencher boom is in the ground and your angle or trench is established, lower the trencher until the
skid shoe is just above ground level. Be certain the optional trench cleaner is operating freely.
You are now ready to trench.
2) During the trenching operation:
A) Use the center trench position whenever possible. You will find it much easier to control the machinery
and dig a straighter trench.
B) Trench at a 45 to 60 degree angle for best performance.
C) Gently creep the loader controls backward. Too much back movement will cause the trencher
to stall.
D) Do not use the “float” control on the loader as this increases drag on the system. You will trench faster
by controlling the depth with periodic adjustments of the boom arms of the loader.
Digging Chain Setup:
In setting up your digging chain for use with width spacers, we recommend using a “V” configuration as a start. One
tooth in the center of the chain acts as the point of the “V” with appropriate spacers and teeth taking a progressively
wider cut in the trench.
After one “V” has cut, another begins the process all over. (See illustration below.)

TROUBLESHOOTING
Shut off power and disconnect power source before performing service checks.
WARNING: Diesel fuel or hydraulic fluid under pressure can penetrate the skin or damage
eyes. Fluid leaks under pressure may not be visible. Never use a bare hand to find leaks
and always wear safety goggles for eye protection. Such fluid, if injected into the skin,
must be removed within a few hours by a doctor familiar with this type of injury. Make
certain pressure is relieved and power source is disconnected before servicing.
Sympton Possible Cause Action
Jerky Cold oil or air in lines
Loader hydraulic pump or system
Give time to warm up.
See loader's manual.
Slow Restriction in lines, couplers,
or in loader's hydraulic system
Worn, damaged, or insufficient loader hydraulic pump
Loader oil filter
Check with pressure
and flow gauge.
See loader dealer.
Request flow and
pressure check.
Check for dirt and grime. See if
filter is installed correctly.
Insufficient
digging
capacity
Hydraulic pump in loader or motor in trencher
ExcessiveLoad
Relief valve
See your dealer.
Request pressure check.
Reduce digging load because load
exceeds capacity of system.
Check for proper
pressure operation
Wrong Direction Hoses not properly connected Reinstall properly.
Oil leaks Hydraulic motor seals are worn or damaged
Loose fittings on hoses or motor
Hoses are loose or damaged
See dealer for replacement of
seals.

Assembly Option
Type of Maintenance
With normal grease gun, apply grease to grease
fitting until full. (Ref. #7 on exploded parts
diagram.)
Tighten nut to 150 lbs/ft. (203 N.m)
Adjust and lubricate. Chain should have
1/2 inch (1.25 cm) of free play.
Adjust and lubricate. Digging chain should have at
least 11/2 inches (4 cm) of free play.
Do not use diesel oil.
Excess chain tension may ruin drive components
and impair performance.
Replace if worn excessively.
Check for wear and the tightness of the two
attaching bolts.
Check mounting bolts for tightness and check free
play in the mechanism at the end of the arm.
* * More often under extreme conditions.
Chain lubricant can be any premium grade grease or commercial chain lube. The lubricant will do its best job when
applied to a warm chain. Give lubricant time to soak into the working parts of the chain before resuming operation.
XR Boom/Chain Tightening
1. Find and expose grease zerk under one of two nylon locking plugs (NLP); usually found under the plug on the
drive chain side of the boom.
2. Loosen the two bolts holding the boom.
3. Use small pumps of grease to extend the boom until there is about 3 cm of free play between middle of boom
and chain.
4. Tighten bolts holding boom 82 lb/ft.
5. Replace Nylon Locking Plugs (NLP)
