SECTION 2 - OPERATION

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.
