Tractor Requirements

!CAUTION!

Your backhoe must be mounted only on a tractor equipped with a Category 1 or 2 hitch or Skid Steer Mounting. Failure to do so may result in serious injury.

NOTE: In order to maintain steering control on your tractor, ballast may need to be added to your tractor. To determine whether or not to add the ballast, refer to your tractor’s operator’s manual.

Skid Steer Requirements

This Backhoe is designed to fit on Skid Steer Loaders with a SAE lift capacity of 1200 lbs. and hydraulic requirements of 11 GPM at 2200 psi minimum. Skid Steer Hitches are available for specific Skid Loaders from your Land Pride Dealer.

Hydraulic System Requirements

Select Hydraulic System

Tractor System

If an open center tractor hydraulic system is utilized, attach the backhoe valve’s pressure hose to the tractor pressure hydraulic outlet, and the backhoe valve return hose to the tractor’s hydraulic oil sump or reservoir tank.

Power Beyond Hydraulic System

If you wish to run both a loader and a backhoe from the same hydraulic system, make your connection as illustrated in Figure 1-1. Also, refer to “Power Beyond Hydraulic Systems” in the section below. Since there are so many variations for this type of setup, we are showing only a generalized hosing scheme. If you have any questions concerning the specifics for your situation, please contact your dealer before attempting operation.

Power Beyond Hydraulic Systems

Power Beyond and Closed Center Kit

For power beyond applications, a Power Beyond and Closed Center Kit # 340-084A must be purchased from your Land Pride Dealer, then the following steps performed:

!CAUTION!

The backhoe valve must be compatible with the hydraulic system that will power it. Make sure that if you are powering the backhoe with an open center hydraulic system, the backhoe is set for open center operation. If you are using a closed center hydraulic system, the valve must be set for closed center operation. If you are using a power beyond set-up, the valve must be converted for this use. See the appropriate section of this manual on how to convert your valve. If you do not know how your valve is currently set-up, check with your Land Pride dealer.

Your backhoe cylinders have been filled with oil at the factory. The oil in the unit is compatible with most tractor manufacturers’ oil. Do not move any control levers on the unit until after hydraulic connections to the tractor or the independent hydraulic system have been made.

The Land Pride Backhoe has been designed to be operated at a flow rate of 6-8 GPM.

Since many tractor systems exceed a flow rate specified for your backhoe, the flow may have to be adjusted by throttling the engine RPM down to obtain an acceptable flow rate. By adjusting the flow rate correctly, you will prevent sudden shock loads on the cylinders, pins, hoses, seals, etc. This results in a smooth operation and reduced maintenance costs and down time.

1.Remove plug (#3) and install Power Beyond Sleeve (#1) in port as shown in Figure 1-1.

2.Install a #8 O-Ring ell (Part # 839-882C) (#2) into closed center sleeve (#1) opening. This converts it to a power beyond sleeve.

3.Install a high pressure hose going to the inlet of another valve (front loader valve). This hose is not furnished.

4.The return hose must be connected to the tractor oil sump.
