SMART TURN™ STEERING
General Information
The Smart Turn Steering™ feature automatically
lowers the speed of the tractor in tight turns.
The decrease in speed is directly proportional
to the sharpness of the turn, up to a maximum
speed reduction of approximately 40% .
The Smart Turn Steering feature permits sharp
turns to be made without always having to
change speed control position. The original
speed is restored as the turn is completed.
Theory of Operation
The steering plate (A) is attached to the speed
control lever (B) on the hydrostatic transmission
through a system of linkage and levers.
When the steering wheel is turned, the linkage
pushes the speed control lever (A) on the
hydrostatic transmission towards the neutral
position and slows the tractor.
