Troy-Bilt 900 Manuel D’Utilisation

Before servicing, repairing, or 

inspecting, always disengage PTO, set parking 

brake, stop engine and remove key to prevent 

unintended starting.

A fuse is installed in your tractor’s wiring harness to protect the 

tractor’s electrical system from damage caused by excessive 

amperage.
If the electrical system does not function, or your tractor’s engine 

will not crank, first check to be certain that the fuse has not 

blown. It is located under the hood, mounted behind the top of 

the dash panel on the support bar.

Always use a replacement fuse with the 

same amperage capacity as the blown fuse.

Shut the engine off and remove 

ignition key before removing the cutting blade(s) for 

sharpening or replacement. Protect your hands by 

using heavy gloves when grasping blades and 

pulleys.

The V-belts found on your tractor are 

specially designed to engage and disengage safely. 

A substitute (non-OEM) V-belt can be dangerous by 

not disengaging completely. For a proper working 

machine, use factory approved belts.

All belts on your tractor are subject to wear and should be 

replaced if any signs of wear are present . To change or replace 

the deck belt on your tractor, proceed as follows:
1. 

Remove the deck as instructed earlier in this section.

2. 

Remove the belt guards by removing the hex washer 

screws that fasten them to the deck. See Figure 7-7.

3. 

Loosen, but do not remove the belt keeper rod on the 

pulley located near the back of the deck. See Figure 7-7.

4. 

Remove the deck belt from around the three spindle 

pulleys and the two deck idler pulleys.
NOTE: The idler pulleys may have to be loosened, but not 

removed, in order to remove the belt from around them.

5. 

To place the new belt, begin by routing the belt around the 

two outer spindle pulleys, then around the front spindle 

pulley as shown in Figure 7-8.

6. 

Route the belt around the two deck idler pulleys as shown 

in Figure 7-8.

7. 

Reinstall the belt keeper rod loosened earlier.

Failure to reinstall the belt keeper rod 

may result in serious damage to your tractor’s PTO 

system. 

8. 

Remount the belt guards removed earlier. 

Re-install the deck making sure the belt remains routed 

around the pulleys as instructed.
