The most stable tiller parked position is the tractor turned ______ degrees in the opposite direction of the ladder.

• A. 30
• B. 60
• C. 90
• D. 15

Answer: (B)

When a tiller is parked, stability comes from how the weight of the ladder (the rear section) is balanced with the tractor, and from keeping clearances so the ladder can’t swing into obstacles. Turning the tractor sixty degrees away from the ladder provides enough offset to keep the ladder clear of curbs, wheels, and other hazards, while still maintaining a stable stance on the parking surface.

If you only angle a little (fifteen or thirty degrees), the ladder and rear setup can still sway or strike nearby objects because there isn’t enough separation. If you turn ninety degrees, the arrangement can become less stable and harder to control, increasing the risk of the ladder or rear overhang catching on things. Sixty degrees offers the best balance between clearance and stability for parking.
