A self propelled irrigation system has a drive tower on which a drive wheel is mounted to a rotating member of a drive mechanism with an axis of the wheel obliquely angled relative to a drive axis of the rotating member such that the wheel is tilted out of a plane normal to the drive axis. A hub has its oppositely facing sides arranged to support the wheel in such an orientation, and may therefore be mounted between the drive mechanism and wheel of a conventional irrigation system in which the wheel and drive axes were previously coincident. The tilt of the wheel causes an intentional wobble under rotation of the hub so that the wheel's point of engagement with the ground wanders back and forth during repeated passage of the drive tower over a particular path, thereby reducing a rut forming or deepening tendency of the irrigation system.
A hub for mounting of a wheel to a drive mechanism installed on a drive tower of a self propelled irrigation system, the hub comprising a hub body having oppositely facing first and second sides, the first side being adapted for connection to the drive mechanism for driven rotation of the hub body thereby about a drive axis and the second side being adapted for connection to the wheel to support the wheel in an orientation where a central wheel axis of the wheel is obliquely angled relative to the drive axis.
A self propelled irrigation system comprising a water supply pipe carried for movement upon at least one drive tower comprising two wheels mounted at a base of the tower support thereof, wherein at least one of the two wheels is mounted to a rotating member of a drive mechanism at the base of the drive tower with a wheel axis of the wheel obliquely angled relative to a rotational drive axis about which the rotating member is arranged to rotate under operation of the drive mechanism such that the wheel is tilted out of a plane normal to the rotational drive axis.
A method of reducing a rut forming or rut deepening tendency of a self propelled irrigation system comprising a water supply pipe carried for movement upon at least one drive tower comprising two wheels mounted at a base of the tower support thereof, the method comprising:
