The EZ Easy Drive system allows the operator controlling the Speedy Wash even with just one hand. The EZ models (Battery or Diesel) come with a pallet-jack type steering control called Easy Drive 4WS (4 wheels steering). The control is hinged to the chassis and is mechanically connected to two wheels, steering them as needed. It allows feather touch steering with minimal effort from the operator.

The mechanism making up the steering is composed by:

• Central drive wheel; 
• Control;
• Driven wheels;
• steering wheels.
