Bush Hog CBH80 - Manual (Page 30)

ASSEMBLY - CBH 60, CBH 70, CBH 80
The backhoe has been partially disassembled and
strapped to a skid for shipping purposes. Initial
installation on the tractor will require a hoist or other
device capable of safely lifting the entire backhoe
from the skid. After the initial installation is com-
plete, the backhoe can serve as its own erecting
hoist, by lowering stabilizers and bucket to the
ground. Additional lifting devices will not be required
for normal removal and reattaching.
IMPORTANT: Tighten all hardware to torque
requirements specified in torque chart.
1, Remove the stabilizer assemblies and any mis-
cellaneous items which have been fastened to the
skid and arrange conveniently.
Reposition stabilizer cylinders from their shipping
configuration by assembling them into the main-
frame, using pins and hardware provided. Be sure
cylinder ports are pointed upward and hoses are
routed above the cylinder to mainframe pivot pin
connection.
2. Support boom and dipperstick with hoist and
remove boom transport lock pin. Lower boom and
manually extend dipperstick until it rests on ground.
Move control handle to “BOOM DOWN” position as
required to aid movement.
