Hydraulic Filter
If your 3PYP has the optional hydraulic drive, it is also
equipped with a high-pressure filter
to protect that
system. With attention to clean connections, the
consumable element in this filter rarely needs replacing.
The filter has a pop-out indicator to alert you that the
filter must be replaced before next use. The element
cannot be cleaned and re-used; it must be replaced.
If you keep a spare filter on hand, replace the element
when the indicator pops. If you don’t keep a spare, plan
on seasonal element replacement.
Note: For extended element life, clean all hydraulic
quick-connects before making connections, and
never let them fall to the ground.
High Pressure Fluid Hazard:
Escaping fluid under pressure can penetrate the skin, causing
serious injury. Avoid the hazard by relieving pressure before
disconnecting hydraulic lines. Use a piece of paper or
cardboard, NOT BODY PARTS, to check for suspected leaks.
Wear protective gloves and safety glasses or goggles when
working with hydraulic systems. If an accident occurs, seek
immediate medical assistance from a physician familiar with
this type of injury.
Replacing Hydraulic Filter
Have cleaning rag, plus a pail ready to catch excess
hydraulic fluid. Even with the system depressurized back
to the tractor, there will be some spillage.
Refer to Figure 126

“float” and shutdown tractor. Allow oil to cool.
