Abstract
A combine harvester with a variable length wheelbase. For example, a combine harvester may have a chassis defining a forward end and a rear end, a feeder house at the forward end of the chassis, a first set of ground-engaging elements supporting the forward end of the chassis, and a second set of ground-engaging elements supporting the rear end of the chassis. The second set of ground-engaging elements are configured to move forward and rearward relative to the chassis.
Claims9
A combine harvester comprising:
- a variable length wheelbase;
- a main body;
- a pair of rear wheels configured to move forward and rearward relative to the main body;
- a rear axle bar mounted on a longitudinal member protruding rearward from the main body, wherein the pair of rear wheels is mounted on the rear axle bar, wherein the longitudinal member is fixedly mounted on a suspension element;
- a wheelbase extension actuator, wherein a first end of the actuator is fixed to the suspension element and a second end of the wheelbase extension actuator is fixed to the rear axle bar so that actuation of the wheelbase extension actuator moves the pair of rear wheels forward and rearward relative to the main body;
- and
- a pitch control actuator configured to pivot the suspension element up and down relative to the main body to alter a pitch measurement of the main body, wherein when the pitch control actuator is extended to its fullest to alter the pitch measurement, activation of the wheelbase extension actuator results in further pivoting of the suspension element to further alter the pitch measurement of the main body.

- a rear axle bar mounted on a longitudinal member protruding rearward from the main body, wherein the pair of rear wheels is mounted on the rear axle bar, wherein the longitudinal member is fixedly mounted on a suspension element;
- a wheelbase extension actuator configured to control the forward and rearward movement of the rear axle bar along the longitudinal member, wherein the actuator is mounted above the longitudinal member;
- and
- a pitch control actuator configured to pivot the suspension element up and down relative to the main body to alter a pitch measurement of the main body, wherein when the pitch control actuator is extended to its fullest to alter the pitch measurement, activation of the wheelbase extension actuator results in further pivoting of the suspension element to further alter the pitch measurement of the main body.
