Section 1 Assembly and Set-Up
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.
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
!
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.
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.
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:
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.
