Kingpin assembly for a three-wheeled agricultural applicator

摘要

A frame assembly is configured to enhance control and maneuverability of a three-wheeled agricultural applicator. The frame assembly includes a fork assembly mounted on a single front wheel assembly having a single front floatation tire. The front floatation tire generally includes a tread having a central crown, a first tread face extending in one direction from the crown, and a second tread face extending in a second direction from the crown opposite the first tread face. The frame assembly includes a spindle housing having an opening with a central axis aligned at an angle from vertical and configured to receive a kingpin extending upward from the fork assembly. When turning the agricultural applicator at a turn angle from a straight-forward direction of travel, the angle of the kingpin causes the vertical alignment of the crown of the front tire to roll a roll angle from vertical.
