In the stall range (when travel speed is
around 0 km/h {0 MPH} ), the equiva-
lent rim pull when traction control is
OFF (MAX) can be performed.

Level 1 (Low)
Use this to keep the rim pull at small
level for a particular purpose.
(C) -
Tires will not easily slip and operation on a slippery
ground such as a snow removal work can be per-
formed easily, because an appropriate driving force is
obtained.
Moreover, the machine may start smoothly and a sud-
den start at forward travel may not occur.
(*1): When the traction control is set to OFF (MAX), the maximum rim pull can be performed over all speed
ranges. When the machine is operated in the stall range (when the travel speed is around 0 km/h), however, the
machine operation can become easier by setting the traction control to ON when tires slip.
(*2): Optimum control of the HST pump and HST motor according to the work load is performed and it can re-
strain the fuel consumption.
