PART “A” 

 

BLADE CARRIER REMOVAL 

 

This operation should be performed by an authorized dealer or a qualified technician. The

 

blade carrier 

weighs  approximately  600  pounds.  Should  it  unexpectedly  shift  during  removal,  it  could  result  in 
personal  injury.  An  overhead  hoist  with  the  appropriate  lifting  capacity  is  recommended  for  this 

operation. 

 

1.  Set the Brush Cutter flat on the ground. Turn the skid loader engine off to disconnect the hydraulic hoses 

from the loader. Then, safely disconnect the Brush Cutter from the loader. 

 

2.  Attach the hoist to the two lifting points on the push bar. 

 

3.  Lift the front of the Brush Cutter, allowing it to lay back upside down, while blocking and bracing the rear 

of the Brush Cutter to protect the motor cover and hydraulics. 

 

4.  Block the Brush Cutter to ensure that it is stable. 

 

5.  Attach the hoist to the blade carrier and apply very light tension. This is a safety precaution to be taken 

before removing the cap screws. 

 

6.  Remove the (8) cap screws and (8) washers that secure the blade carrier to the drive flange, and lift the 

blade carrier with the hoist. 

 
 

PART “B” 

 

BLADE CARRIER INSTALLATION 

 

1.  With the Brush Cutter laying upside down and blocked up for stability, attach a hoist to the blade 

carrier and lift it into place. Align the holes on the blade carrier to the holes on the drive flange. 

 

2.  Reinstall the (8) cap screws and (8) washers, securing the blade carrier to the drive flange. A permanent 

threadlocker should be applied to the cap screws before installation. 

 

3.  Attach the hoist to the lifting points on the push bar. 

 

4.  Lift with the hoist to set the Brush Cutter back on the ground in its normal position.
