The Troy Bilt Super Bronco has transmission fluid inside the drive system of the tiller. You must check the fluid level when preparing the tiller for gardening season. Low fluid level will cause the tines to bind and prevent the tines from rotating. The low fluid level will also cause the internal components of the transmission to wear prematurely.
The rototiller uses a drive belt to turn the transmission and tines of the Super Bronco. Over time, the drive belt can stretch and wear. The tines will begin to bind or slip once this problem occurs. A new drive belt that has been misaligned will also cause the tines to bind when operating the tiller. Without a proper maintenance inspection on the Troy Bilt tiller, the belt can wear to the point of breaking and cause the tines to bind.
The transmission on the Troy Bilt Super Bronco turns the tines will a pulley. A loose or damaged bolt can cause the pulley system to become misaligned and the tines will bind. The pulley will begin to wobble and slowly wear down the bushings or bearings. As the wear becomes more prevalent, the tines will begin to bind or loose turning power. Once this occurs, the Super Bronco will not till the soil.
One of the common problems for the tines or tiller to bind is the improper use of the controls of the Super Bronco. Make sure you read the owner's manual before operating this piece of equipment or you can cause the tines to bind. If the transmission is not engaged, the tines will not turn.
The tines are the forks of the Super Bronco that till the soil. If you till a garden that has a lot of weeds or overgrowth on top of the soil, the weeds will accumulate in the tines of the tiller. The accumulation of debris in the tines or drive shaft of the Troy Bilt will cause the rototiller to bind. Make sure you periodically clean the debris from the forks of the tiller to prevent this problem from occurring.
