QUICK COUPLERS
Each remote valve section has a set of hydraulic
quick couplers, 1, located at the rear of the
tractor. These are self-sealing, leverless
couplers that require no tools for connecting and
disconnecting hoses. These couplers also
permit hoses to be pulled from the coupler if an
implement should become disconnected from
the tractor.
The upper couplers are the “retract/lower”
couplers and the lower couplers are the
“extend/raise” couplers.
Each set of couplers has a decal next to it to
identify which remote lever they are hooked to
and which coupler extends or retracts a cylinder.
Excess oil drain hoses, 2, are attached to each
coupler to drain away oil released during
connection and separation of the couplers.
The couplers will accept standard 12mm (1/2″).
SAE or ISO tips. The couplers can be connected
or disconnected under pressure.

COUPLER CONNECTION
1. To connect couplers, wipe the outside of the
coupler and the tip of the implement to
remove any dust and minimize
contamination.
2. Insert the coupler tip through the seal and into
the coupler, making sure the coupler is
properly seated.
3. Actuate the remote valve to supply hydraulic
pressure which will complete the hydraulic
coupling of the tractor and implement.
