INSTALLING MOUNT AND HYDRAULIC COMPONENTS
CAUTION: Before leaving tractor seat, stop engine, lock brake, relieve hydraulic pressure and remove key.
CAUTION: Do Not allow bystanders in work area.
Installation Notes
• Remove all mounting brackets from crate.
• Clean threaded holes in the tractor frame with a tap of the proper size. Paint, rust and/or debris in threads may cause bolts to mis-align or not tighten correctly.
• This mounting kit may have both metric and standard NF (fine thread) or NC (course thread) fasteners. Insure that the proper fasteners are used in the correct locations.
• Leave all mounting hardware loose until mounting kit is completely installed.
• After the mounting kit installation is complete, tighten all hardware to the specifications given in the bolt torque chart or per specifications given in instructions.
• After the first hour and then after every 4 hours for the first day of operation, all mounting hardware should be checked for proper torque specifications.
Tractor Preparation
Tractor will require setup, please consult your Backhoe Operator’s Manual for proper ballasting and other important safety precautions.
Installation of the Backhoe on to the tractor will require that a loader has already been installed.
NOTICE: If equipped, remove loader rear ballast.
NOTICE: Remove tractor 3-point center link, lift links and lower draft arms before proceeding and hydraulically raise 3-point. Refer to your Tractor Operator’s Manual for proper removal procedure.
NOTICE: Removal or reposition of tractor draw bar may be necessary.
NOTICE: Some loader mounting components attached to tractor may be removed and discarded.
NOTICE: Remove belly mower (if so equipped) from tractor to allow backhoe to be installed. See figures 1 and 1A for components to be removed and figures 2 and 2A for components that remain on the tractor. Figures 1 and 2 refer to mowers with serial numbers 2999 and lower. Figures 1A and 2A refer to mowers with serial numbers 3001 and higher. See your Mower Deck Manual for assembly and removal of mower components.
NOTICE - To ease installation of backhoe mounting components to tractor, the removal of the rear tires is recommended.
1. Turn off the ignition, engage the parking brake and block the front tires.
2. Using a jack or chain hoist, carefully raise the rear of the tractor until the rear tires are approximately 1” - 2” off the ground.
NOTICE: For overall unit stability during installation, do not raise rear end higher than required for wheel removal.
3. Support the rear of the tractor on jack stands positioned under the rear axles.

ASSEMBLY INSTRUCTIONS - HYDRAULICS
Avoid High Pressure Fluids
ESCAPING fluid under pressure can have sufficient force to penetrate the skin and cause serious injury. Be sure to stop engine and relieve all pressure before disconnecting lines. Be sure all connections are tight and that lines, pipes, and hoses are not damaged before applying pressure to the system. Fluid escaping from a very small hole can be almost invisible. Use a piece of cardboard or wood, not your hands, to search for suspected leaks. SEE A DOCTOR at once if injured by escaping fluid. Serious infection or gangrene can develop if proper medical treatment is not administered immediately.
NOTICE - Follow instructions carefully when connecting backhoe to tractor hydraulic system.
INSTALLING BACKHOE HYDRAULIC HOSE LINES FOR TRACTOR
