Procedures: Remove Blade Bar
1. Clean all components of Boom and Head, Remove all Dirt and any other material that may
contaminate components as being dis-assembled or after it has been disassembled.
2. Move Tractor to Level and Firm Ground, Concrete Floor is Best.
3. Swing the Boom to the Side of the Tractor; Extend Boom out till fully extended. Stand Head Up
so Blade Bar is facing out away from Tractor in the folded up position.
4. Fully apply the Park Brake on Tractor.
5. Place all Gears in Tractor in the Neutral Position.
6. Shut Off Tractor, remove Key and disable Tractor so it cannot be started till you are ready
to have it started.
7. This procedure can be done with head connected to Boom or with it removed, But if removed
you will have to lift Head to remove Blade Carrier Assembly.
8. Remove Blade Bar Assembly, Use Caution the Blade Bar is very heavy Do Not remove the
retaining bolts till it is secure to where it will not fall. An easy way to support Blade Bar when
removing it is to only remove 2 of the 4 retaining bolts. Get 2 long bolts with same size and
threads but longer than what was removed, cut the heads off of these 2 longer bolts and screw
them in where you removed the 2 retaining bolts. This will support Blade carrier while you
remove the other 2 bolts, this allows the Blade carrier to slide off. The four Blade Bar Retaining
Bolts are Torqued to 400 ft. lbs. and are tight. It may be required to hold Blade Bar when
removing them, This can be done by connecting a Chain to Blade Bar and securing it to Deck.
Make Note of the length of the four Blade Bar Retaining Bolts in center Blade Bar (See Figure
85), Never put Bolts back in that are longer or Shorter they will damage Spindle Shaft.
9. It will not be required to dis-assemble Blade Bar Carrier Assembly once it has been removed
from Spindle. But if you do dis-assemble it the 4 Blade Bar Assembly Bolts, 2 long and 2 short,
are torqued to 2000 ft. lbs., Blade Bolts Torque to 400 ft. lbs. These Torque Values are based
on Clean, Lubricated and undamaged threads. These Components must be torqued back to
these setting when re-assembled.
