Abstract
A lift and gauge wheel lift mechanism has a hydraulic lift cylinder pivotally connected to a lift mechanism rocker link. A rear lift wheel link is pivotally connected to the lift mechanism rocker link. The rear lift wheel link is pivotally connected to either a rear lift wheel arm having at least one rear lift wheel attached. A gauge wheel link is pivotally connected to the lift mechanism rocker link. The gauge wheel link is pivotally connected to a gauge wheel parallel arm bell crank. The gauge wheel parallel arm bell crank is attached to either a gauge wheel upper parallel arm, or to a gauge wheel lower parallel arm. At least one front gauge wheel is connected to the gauge wheel upper parallel arm and to the gauge wheel lower parallel arm.
