What are the defects?
The pilot control valve in the hydrostatic transmission may be sensitive to oil contamination and oil temperature.
What should consumers do?
Pilot valves need to be replaced with new valves. In addition, new steering control software, harness and sensors need to be installed to turn off the pilot control supply pressure and apply the brakes in the event of a pilot control valve sticking.
Australian Competition and Consumer Commission is the responsible regulator for this recall.
