TROUBLESHOOTING GUIDE
HYDRAULIC CYLINDER NOT WORKING - Check level of hydraulic fluid (see sight gauge on tank). Check to
see if pump is functioning properly by attempting to use another cylinder or pressure gauge. If pump is working
properly, check the pressure on the line. The relief valve may be by-passing fluid at too low pressures. If
cylinder is still not functioning properly, check the line for stoppage. The pistons in hydraulic cylinders are
virtually trouble-free, but occasionally one will have a scored wall and allow oil to flow around the piston. In this
case, replace the cylinder.
NOTE: Refer to repair parts section on valve bank settings on individual relief cartridges.
HYDRAULIC MOTOR NOT WORKING - Check lines for kinks or if they are pinched. If the motor is “bogging
down” under load, recheck the relief valve setting on the cutter valve.
HYDRAULIC VALVE - Failures in the hydraulic system are almost always caused by other elements in the
system other than the valve; so the entire system should be checked before the valve is changed. A
malfunction In any hydraulic valve section will require replacement of that section (but not the replacement of
the valve bank) since the insides are honed to fit individually. Attachments such as the relief valves and detent
may be serviced individually.
STRUCTURAL MEMBERS
Failure in structural members generally results from rough treatment. While they are constructed to withstand
abuse, they cannot be made strong enough to withstand abnormal abuse. The factory does not warrant these
parts to any extent other than in normal use in grass, weeds, brush, small bushes, and small trees which the
unit is designed to cut. This mounted implement removes weight from front wheels and can cause loss of
steerage with possible overturn. Add front end weight until 20% of tractor original weight is on front wheels
when boom is in transport position for steering safety and prevention of bodily injury. Transport slowly on
rough surface to prevent bouncing front wheels off surface with loss of steerage and possible injury
