Page 10: Features And Controls
Wheel Drive Pins are placed only through the holes in the wheel shaft (not the wheel hubs), thus allowing the wheels to turn freely when the tiller is pushed or pulled by hand. To Place the Wheels in WHEEL DRIVE or FREEWHEEL: 1. -

Page 16: Tilling Tips & Techniques
Tilling Tips Let the tiller do the work • While tilling, relax and let the wheels pull the tiller along while the tines do the digging. Walk on the side that is not yet finished (to avoid making foot- prints in the freshly tilled soil) and lightly, but securely grip the handlebar with just one hand. - Page 17 6" to 12"). This “fishtailing” action often clears the tines of debris. • If tangling occurs, lift the tines out of the soil and run the tiller in reverse for a few feet. This reversing action should unwind a good deal of debris.

Questions and answers
wheels locking up
The wheels on the Troy-Bilt Bronco 12180 may be locking up because the wheel drive pins are inserted through the wheel hubs and wheel shaft, which locks the wheels to the shaft and causes them to turn when the Forward Clutch Bail or Reverse Clutch Control is engaged. This is the WHEEL DRIVE mode. If locking is not desired, the wheel drive pins should be removed to allow freewheeling when the engine is off.
