Steering Response Adjustment

There are three settings on this Riding Trowel for steering response. Some operators like a fast 
response to steering while others would rather have a slower response when pressure is applied to the 
operator joysticks. The following illustrations show each appropriate setting on the lower control arms 
to achieve the desired response. 

NOTE

: The faster setting makes the joysticks “tighter” to the operator and more force will be required 

to move the joysticks.
