Using Tractor Hydraulics All Tractors

If you wish to use the tractor hydraulic system, consult the dealer of your tractor for a safe and proper method of connecting the Land Pride BACKHOE to your tractor.

Using Tractor Hydraulics John Deere

The return hose supplied with your Backhoe will not be long enough. You will have to purchase a 1/2” return hose with a length suitable for the following procedure.

Purchase a Port Filter Cover (JOHN DEERE Part number AT301970) from your dealer if filter cover is not already ported for an auxiliary return line. Install it on your tractor.

NOTE: Many newer John Deere tractors will already be equipped for this return hose porting through filter cover cap back to transmission sump.

Attach the backhoe’s pressure hose to the tractor quick coupler. Attach the backhoe’s return hose to the port filter cover that you installed. Move the control lever on

the tractor so that it starts a flow to the backhoe valve, and secure it in full open position.

The above procedure results in a direct connection to the JOHN DEERE master pump, and eliminates a return into the rear transfer pump chamber. The problem with returning oil into the rear transfer pump chamber is that if the tractor engine RPM is throttled down to a point at which the oil transfer pump cannot supply sufficient oil to the main system pump, the main pump runs out of oil in its sump and starts chattering.

Mounting The Backhoe

IMPORTANT: Make sure that there is sufficient clearance for the operator if the backhoe is mounted to a tractor with a cab or is equipped with a ROPS. The ROPS may need to be extended or flipped around to obtain sufficient clearance.
