EXTERNAL AUXILIARY HYDRAULICS
Auxiliary hydraulics are installed to operate implements
requiring external hydraulic source for operation. Kits
are available as two-spool (two hydraulic circuits).
FIG. 5-40: Control lever, 1, controls implement raising/
lowering when first set of remote couplers are used.
Control lever, 2, controls implement when second set of
remote couplers are used.
Control levers are spring-loaded to center neutral
position, from normal raise or lower positions.
FIG. 5-41: Remote couplers are located at rear of
Tractor, above three-point hitch, or, under right step
(depending on kit installed). Rear location shown.
Coupler set, 1, corresponds with control lever, 1, coupler
set, 2, with control lever, 2.
Implement hoses must be connected to each coupler
set so when respective control lever is pulled rearward,
implement raises and, when pushed forward, implement
lowers. Male coupler tips (on implement hoses) must
be compatible with Tractor couplers and must also be
inserted fully and locked into Tractor couplers to operate
correctly.
CAUTION: Always lower implement to
ground, shut off engine and relieve system
pressure (by operating control levers
with engine off) before connecting or
disconnecting implement hoses.
CAUTION: Make sure all hydraulic hoses,
couplers and cylinders are in good
condition before use. Damaged equipment
is dangerous.
FIG. 5-42: Most implements require double-acting
hydraulics. Each implement cylinder will have two hoses
connected to it.
When single-acting service is required (cylinder with only
one hose), the inner
鄭
coupler will be used and selector
function, 1, must be turned to the left.
NOTE: For normal double-acting operation selector
function must be turned to the right.
