Tiger JD 62-6420 manual Assembly Main Boom Installation, Switching Side Mount To Boom Arm

ASSEMBLY

MAIN BOOM INSTALLATION

Install the boom swivel into the main frame as shown in the parts section using a hoist. Line up holes in swivel and main frame for large swivel pin and insert pin. Secure with hardware as shown.

Attach the inner end of the main boom to the swivel bracket with the cylinder anchors positioned upward, and at a right angle to the tractor. Secure it with the horizontal hinge pin. Secure the hinge pin in the boss with capscrews, etc. (see parts section).

Attach the butt end of the main boom cylinder to the swivel bracket anchor with the special “bracket head” cylinder pin and roll pin shown in parts section.

Install the travel lock on the butt end of the main boom cylinder. This should be facing the butt end of the cylinder after installation.

Install the fittings and hoses to the main boom cylinder per parts section.

GREASELESS BEARINGS ARE DARK GRAY AND SHOULD NEVER BE GREASED. THE MAIN BOOM CYLINDER AND THE SECONDARY CYLINDER ARE NOT GREASELESS AND NEED TO BE GREASED.

SWITCHING SIDE MOUNT TO BOOM ARM

If you are changing over from a side mounted mower you must first close the ball valves and remove the motor hoses from the motor to the solenoid valve. Also remove and replace any fittings that do not match the ones shown in the parts section diagram.

Next, disconnect all hoses from the control valve. Remove the pin that connects the lift cylinder to the mast on the main frame. Remove the inner draft beam pin.

At this point the mower should be loose from the tractor.

Remove the two spool valve and mount the four spool valve for the boom according the diagram in the parts section. Also refer to the parts section for the new hoses that will need to be used.

DECK ATTACHMENT

The pivot assembly is used to attach the head to the secondary boom. Install the deck pivot cylinder using the pins and hardware, which is illustrated in the common section.

Connect the fittings and hoses from the pivot cylinder to the small preformed tubes on the boom arm. Connect the fittings and hoses from the motor to the large preformed tubes on the boom arm. Connect all remaining hoses from the control valve to the cylinders and / or preformed tubes on the boom arm. Refer to common section for diagrams.

SOLENOID BRAKE VALVE

Install a solenoid valve mounting bracket with the supplied hardware. While installing fittings to the brake valve, the electrical coil on the spool must be removed to make room. When reinstalling the coil, it is important to use no more than 5 ft. lbs. (or 60 in. lbs.) torque. Over torque to the coil will result in hydraulic failure of spool.
