Troy-Bilt RZT Benutzerhandbuch

Working from the middle of the tractor, pivot the idler 
bracket and movable idler pulley rearward away from 
the backside of the ‘V” belt just far enough to lift the 
belt up and over the idler pulley. See Figure 7-3.

From beneath the rear of the tractor, slide the belt off 
of the PTO pulley on the bottom of the engine.

Using the deck lift handle, raise the deck to the  
position that provides the most horizontal run of the 
belt between the deck idler pulleys and the PTO pulley 
on the bottom of the engine.
Sitting behind the tractor facing forward, reach 
beneath the tractor to grasp the belt at the front of the 
PTO pulley.

WARNING!: Use caution to prevent pinching 
your fingers when rolling the belt off the PTO 
pulley. 

Pull the left side of the belt rearward and downward 
while manually turning the PTO pulley to the right until 
the belt rides out onto the edge of the lower sheave of 
the pulley. NOTE: If pulling the right side of the belt, turn 
the pulley to the left.
While still holding the belt downward, continue turning 
the PTO pulley until the belt is rolled off the pulley. 
Refer to Figure 7-5.
Lower the deck to the ground using the deck lift 
handle.
Locate the LH and RH deck support pins on each side of 
the deck. Pull the deck support pins outward and lock 
in the disengaged position to release the deck from the 
tractor’s LH and RH deck lift arms. Refer to Figure 7-4.
Raise the deck lift arms out of the rear hanger bracket 
slots by raising the deck lift handle on the tractor to its 
highest position. Refer to Figure 7-4.
Slide the deck forward so that the deck front hanger 
rod can be lifted out of the two slots of the front deck

bracket. After lifting the front hanger rod out of the 
slots, slide the deck rearward so that the rod can no 
longer engage the slots.

Using care to prevent the front hanger rod from falling 
back into the deck bracket slots, carefully slide the 
cutting deck (from the right side) out from underneath 
the tractor. 

To install the mower deck, proceed as follows:

While holding the deck front hanger rod upward, 
carefully slide the deck underneath the right side of the 
tractor. 
While still holding the front hanger rod, slide the deck 
forward until the front hanger rod can be lowered into 
the slots of the front deck bracket.
Lower the front hanger rod into the slots of the front 
deck bracket, then slide the deck rearward.
Maneuver the deck so that the slots in the two rear 
deck hanger brackets approximately align with the 
deck lift arms of the tractor. Refer to Figure 7-4.
Use the tractor deck lift handle to lower the deck lift 
arms into the slots of the rear deck hanger brackets.
Pull the deck support pins outward and maneuver the 
deck as necessary to align the holes in the deck lift arm 
with the pins. Refer to Figure 7-4.
When aligned, push each pin fully inward through the 
lift arms to secure the arms in the rear hanger bracket 
slots.
Make certain the ‘V’ belt is in the spindle pulleys on the 
deck; then route the belt rearward beneath the tractor 
frame, above the transmission tube(s), to the PTO 
pulley on the bottom of the engine. 
Install the ‘V’ belt onto the PTO pulley using one of the 
following two methods.

WARNING! : The muffler at the rear of the 
tractor may be extremely hot, and could cause 
serious burns. Use extreme caution when near 
the muffler. Allow the muffler to fully cool 
before installing the belt.
