ABSTRACT:
A neutral adjustment mechanism for dual lever steering controls. The dual lever steering controls include two levers that are each independently pivotable forward and reverse to drive a zero turning radius mower. The neutral adjustment mechanism includes a control pivot connected to each lever of the dual lever steering controls that pivots with forward and reverse pivoting of each lever. A steering link has a first end with an adjustment point, a ball joint adjacent the adjustment point connecting the steering link to the control pivot, and a second end pivotably connected to an input control lever of a hydrostatic transmission pump. An operator seat may be positioned over the steering links. Under the operator seat, adjustment access holes are provided for adjusting the steering links while the operator seat remains in place.
