Abstract
An agricultural machine includes a frame having a tongue hitch for attachment to a towing vehicle, the tongue hitch being oriented along a longitudinal axis inline with the direction of travel. The agricultural machine has running gear configured to support the frame. The running gear includes an axle mounted to the frame and a swing arm pivotably mounted to the axle defining a main pivot axis. A front spindle is mounted at the front end of the swing arm with a front tire mounted to the front spindle and a rear spindle is mounted at the rear end of the swing arm with a rear tire mounted to the rear spindle. The tires are positioned on a same side of the swing arm. The front tire has a smaller diameter than a diameter of the rear tire.
Claims17
An agricultural machine configured to travel through a field in a direction of travel, the agricultural machine comprising:
- a frame having a tongue hitch for attachment to a towing vehicle, the tongue hitch being oriented along a longitudinal axis L which is generally inline with the direction of travel;
- and
- at least one set of running gear configured to support the frame for movement through the field, each at least one set of running gear comprising:
- an axle mounted to the frame;
- a swing arm pivotably mounted to the axle defining a main pivot axis, the swing arm having a front end and a rear end relative the longitudinal axis L with the main pivot axis in a portion located between the front end and the rear end;
- a front spindle mounted at the front end of the swing arm with a front tire mounted to the front spindle;
- and
- a rear spindle mounted at the rear end of the swing arm with a rear tire mounted to the rear spindle;
- wherein the front tire and the rear tire are positioned on a same side of the swing arm with the rear tire longitudinally behind the front tire such that they are inline with each other so as to form an inline tandem running gear;
- and
- wherein the front tire has a smaller diameter than a diameter of the rear tire.
An agricultural machine comprising:
- a frame having a tongue hitch oriented along a longitudinal axis for attachment to a towing vehicle;
- and
- at least one set of running gear comprising:
- an axle mounted to the frame;
- a swing arm having a front end and a rear end relative the longitudinal axis of the frame and a first side generally parallel the longitudinal axis, wherein the swing arm is pivotably mounted to the axle between the front end and the rear end;
- a front spindle mounted to the first side of the front end of the swing arm;
- a rear spindle mounted to the first side of the rear end of the swing arm;
- a front tire having a first diameter mounted to the front spindle;
- and
- a rear tire having a second diameter mounted to the rear spindle, wherein the second diameter is larger than the first diameter.
