  • Patent number: 11406062
    Abstract: An agricultural harvester, such as a combine harvester, which has an auxiliary axle assembly for support of the feeder house of the harvester. The auxiliary axle assembly can be provided in a retracted position when in a field mode, and can be locked in an extended position when in a road mode, where a wheel of the assembly contacts the ground. When in the locked, extended position, the auxiliary axle assembly supports substantially all of the weight of the feeder house and any attached implements, allowing the feeder house to pivot relative to the main chassis of the harvester.

  • Patent number: 10323387
    Abstract: A bucket level indicator mechanism for use with work machine with a front mounted loader implement includes a carriage assembly having a carriage frame comprising a carriage back and first and second carriage endplates at longitudinal ends of the carriage back, a first end of the carriage assembly being pivotably connected to one of the masts, wherein the carriage back has a slot formed therein along a portion of its longitudinal length. At least one guide rod extends between the carriage endplates. A boom height compensating link is mounted on the upper arm section. The boom height compensating link has at least one fixed traveler configured to be received in the slot in the carriage back, the carriage assembly being mounted so as to slide relative the traveler, wherein as the loader boom is raised and lowered by extension or retraction of the lift actuator, the carriage assembly rotates relative the mast about a pivot as the traveler slides in the slot in the carriage back.
