Section 1: Assembly and Set-Up
Tractor Requirements
!CAUTION!
Your backhoe must be mounted only on a tractor equipped with a Category 2 and 3 hitch. 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 manual.
Hydraulic System Requirements
!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 setup, 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 setup, check with your Land Pride dealer.
Open Center System
Remove cap from the 1/2” high pressure hose connected to the right hand side of backhoe valve. The high pressure hose may be connected to any high pressure outlet in the tractor system. A tractor remote hydraulic valve is usually the preferable source. An oil quick coupler that is compatible to the oil coupler on the tractor valve is permissible.
The return hose must be connected so that the oil returns directly to the tractor oil sump. DO NOT connect the return hose directly to the tractor remote valve. If the operator would be reversed. This could result in damage to the return hose or the backhoe’s hydraulic valve.
!CAUTION!
The hydraulic valve can be damaged by reverse flow of oil through the valve, disconnecting the return hose while the tractor is running, and by using more than 12 GPM of oil flow while operating. The valve manufacturer will not warrant the valve when damaged under these circumstances.
Closed Center System
Power Beyond Closed Center Kit Part No. 340-084A
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
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.
!CAUTION!
If you are going to use a closed center tractor hydraulic system to power your Land Pride Backhoe, A Power Beyond and Closed Center Kit must be purchased from your Land Pride Dealer, then you must follow carefully the directions below. Failure to do so may cause extensive damage to your tractor and/or Land Pride Backhoe.
