BlADE BAR TIgHTENINg pROCEDURE

FOR All BROWN TREE CUTTERS

On start up of a tree cutter, or after the blade bar has been removed for any reason, the following

steps must be followed:

AFTER THE FIRST HOUR OF OpERATION:

Shut the unit down, lift the cutter deck approximately two feet above the ground. Place jack stands

or blocks under the blade bar. Then lower the cutter onto the stands to support the entire unit’s

weight on the blade bar allowing the output shaft to seat as deep as possible into the hub of the

blade bar. (See diagram), do not rely on the tractor’s lift system to hold the cutter up during any

maintenance procedure. To ensure the hub is seated properly onto the shaft of the gear box, strike

the blade bar several times with a large hammer.

Only at this time can you properly tighten the blade bar nut. Without the weight of the blade bar
being supported by jacks or stands the nut cannot tighten the blade bar securely.

Using a 6 point 2 9/16” socket, part # T5-054AS and appropriate torque wrench, tighten the blade

bar nut to 2200 ft lbs. torque. Continue to tighten until the cotter pin slot is aligned. Insert the cotter

pin.

CAUTION:

Never loosen a blade bar nut to align the cotter pin hole and slot. Always

continue tightening the nut until they are aligned, tightening up to the maximum allowable torque of

3800 lb-ft. If alignment is still not achieved, replace the nut with a new one and repeat the tightening

procedure.

After the nut is properly tightened MAKE SURE you replace the proper size cotter pin in the shaft.

THIS PROCEDURE WILL NEED TO BE REPEATED EVERY HOUR UNTIL THE NUT IS

FOUND TO BE SECURELY TIGHTENED AT THE END OF THE 2ND OR 3RD HOURLY

CHECK, THEN IT WILL NEED TO BE REPEATED ONCE A WEEK AS PREVENTATIVE

MAINTENANCE.

THE BLADE BAR SHOULD BE CHECKED DAILY BY INSERTING A LONG PRY BAR

BETWEEN THE DECK FRAME AND BLADE BAR. USING A PRYING MOTION, VISUALLY

CHECK FOR ANY LOOSE VERTICAL MOTION. IF ANY LOOSE MOTION IS DETECTED,

FOLLOW THE BLADE BAR TIGHTENING PROCEDURE. IF THE BLADE BAR WILL NOT

REMAIN TIGHT, DISASSEMBLE THE UNIT AND CHECK HUB AND SHAFT FOR WEAR.

REPLACE AS NECESSARY.
