valve or other accessory valve is connected to the
tractor system, and whether the tractor has an open-
center system (constant pumping of oil to control
valve and back to reservoir) or a closed-center sys-
tem (no flow of oil until there is a demand at one
hydraulic cylinder). The four hook-up methods are
described below.
IMPORTANT: Follow instructions carefully when
connecting backhoe to tractor hydraulic system.
The decal shown at right is located on the front left
hand side of the control console.
NOTE:
Do not connect hoses from the backhoe
control valve to the tractor hydraulic system until ini-
tial assembly of mounting kit is complete.

When a loader valve or other accessory valve must
be connected to the tractor hydraulic system in addi-
tion to the backhoe control valve, a Power Beyond
Kit is required. This kit converts the backhoe valve so
that pressurized hydraulic oil can be directed to
another open-center valve for a loader or other
accessory. This allows the backhoe valve and the
other valve to be connected to the tractor hydraulic
system simultaneously, without the inconvenience of
using a flow diverting valve.
