Attaching 447 Backhoe To Tractor - Fully lower tractor rockshaft arms. Align rockshaft pins with hooks on 447 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 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. Install hitch pins in L-pins. Park tractor safely. Lower the rockshaft to transfer weight of backhoe from rockshaft arms to L-pins.

Routing Hydraulic Hoses - Position drain pan and remove male coupler from 90° elbow on backhoe pressure hose. Route backhoe pressure hose up through backhoe right side. Install male coupler back on 90° elbow. Route backhoe return hose up through backhoe left side. It may be necessary to remove the female coupler to allow the hose to fit.

Connecting Hydraulic Hoses - Park JD 4300 tractor safely with L-pins installed in 447 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 pressure hose with male coupler to female coupler. Connect backhoe return hose with female coupler to fitting.
