Abstract
One example provides a ride on air injection machine including one or more steerable wheels, a compressed air system providing compressed air, one or more air inject tines to inject compressed air from the compressed air system into the grounds, and a steering system. The steering system includes a steering wheel, a cylinder coupled to the steerable wheels, the cylinder including opposing internal chambers and being moveable to steer the steerable wheels and a control valve assembly to direct compressed air from the compressed air system to the internal chambers and to bleed compressed air from the internal chambers based on a position of the steering wheel to move the cylinder steer the steerable wheels.
Claims20
A ride on air injection machine comprising:
- one or more steerable wheels;
- a compressed air system providing compressed air;
- one or more air inject tines to inject compressed air from the compressed air system into the ground;
- and
- a steering system including:
- a steering wheel;
- a cylinder coupled to the steerable wheels, the cylinder including opposing internal chambers and being moveable to steer the steerable wheels;
- and
- a control valve assembly to direct compressed air from the compressed air system to the internal chambers and to bleed compressed air from the internal chambers based on a position of the steering wheel to move the cylinder to steer the steerable wheels.
A ride on air inject machine comprising:
- one or more steerable wheels;
- a compressed air system to provide compressed air;
- a plurality of ground insertable air inject tines to inject compressed air from the compressed air system below a surface of the ground;
- and
- a pneumatic power assist steering system to receive compressed air from the compressed air, the compressed air to assist with steering of the steerable wheels.
A pneumatic steering system for a turf maintenance machine having at least one steerable wheel, the pneumatic steering system comprising:
- a piston including:
- a piston rod;
- and
- a cylinder disposed about the piston rod, the cylinder in mechanical communication with the at least one steerable wheel, the cylinder having a pair of opposing internal chambers to hold compressed air, based on a differential in pressure between compressed air held in the opposing internal chambers, the cylinder to move back and forth along the piston rod to steer the at least one steerable wheel.
