Attaching 375 Backhoe To JD 3320 Tractor - Lock folding ROPS in full upright position. Close and lock cab rear window. Fully lower tractor rockshaft arms. Align rockshaft pins with hooks on backhoe, and back tractor into
position. Check to be sure backhoe hydraulic hoses are clear of backhoe hooks and hardware. Slowly lift rockshaft arms, making sure pins engage into hooks on backhoe. Check to be sure both lower pins on backhoe engage both hooks on tractor RSA mounting plates. Fully raise rockshaft arms so stop is against edge of RSA mounting plates. Install L-pins in 375 backhoe and RSA mounting plates. If backhoe and RSA mounting plates do not align, and L-pins do not slide in and out easily, lower backhoe to ground and adjust movable latch plates (H). Left and right movable latch plates may need different adjustment. Install hitch pins in L-pins. Park tractor safely. Lower the rockshaft to transfer weight of backhoe from rockshaft arms to L-pins.

Connecting Hydraulic Hoses - Stop engine and park tractor safely with L-pins installed in backhoe. Cycle the rockshaft control lever to relieve all pressure on rockshaft. Disconnect Power Beyond hose from female coupler. Install dust cap on hose, and lay hose aside on backhoe frame. Connect backhoe return hose with female coupler to fitting. Connect backhoe pressure hose with male coupler to female coupler.
