Troy-Bilt Super Bronco 사용자 설명서

If the drive belt or reverse drive belt needs to be replaced, see your 

local authorized dealer or refer to the Replacement Parts Section 

for ordering information. Use only a factory-authorized belt as 

an “over- the-counter” belt may not perform satisfactorily. The 

procedure requires average mechanical ability and commonly 

available tools.
NOTE: When reinstalling the belt cover, be sure to engage the 

bail and hold it so that the drive belt is tight before attempting to 

reinstall the belt cover. This will enable the belt to fall under the 

belt keeping mechanism built into the belt cover. Failure to do so 

could damage the belt and/or belt cover.

The bolo tines will wear with use and should be inspected 

at the beginning of each tilling season and after every 30 

operating hours. The tines can be replaced either individually 

or as a complete set. See the Replacement Parts Section for tine 

identification and part numbers.

With use, the tines will become shorter, narrower and pointed. 

Badly worn tines will result in a loss of tilling depth, and reduced 

effectiveness when chopping up and turning under organic matter. 
Refer to Fig. 7-1 for the following tine procedures.

1. 

With the engine shut off and the spark plug wire 

disconnected, remove the two hex screws (3⁄8-16 x 1.00) 

and hex lock nuts (3⁄8-16) that attach a single tine to a tine 

holder. If needed, use penetrating oil on the nuts.

2. 

When installing a single tine, be sure to position it so that 

its cutting edge (sharp) will enter the soil first as the tiller 

moves forward.

1. 

A tine assembly consists of eight tines mounted on a tine 

holder.

2. 

If removing both tine assemblies, mark them “left” and 

“right” before removal. Remove the hex screw (3⁄8-16 x 1.75) 

and flange lock nut (3⁄8-16 ) that secure the tine assembly to 

the tine shaft. If necessary, use a rubber mallet to tap the tine 

assembly outward off the shaft. 

3. 

Before reinstalling the tine assembly, inspect the tine 

shaft for rust, rough spots or burrs. Lightly file or sand, as 

needed. Apply a thin coat of grease to the shaft. 

4. 

Install each tine assembly so that the cutting (sharp) edge 

of the tines will enter the soil first when the tiller moves 

forward. Secure the tine assembly to the tine shaft using 

the screw and locknut. 

NOTE: The transmission gear oil does not need to be changed 

unless it has been contaminated with dirt, sand or metal 

particles. 
1. 

Drain the gasoline from the fuel tank or run the engine 

until the fuel tank is empty.

2. 

Drain the oil from the engine. 

3. 

Remove the hex washer screw (1⁄4-20 x .500) and flat washer  

(.28 x .74 x .500) from the left side of the belt cover and the 

hex washer screw (1⁄4-20 x .500) from the right side of the 

belt cover. Remove the belt cover. See Fig. 7-2.
