Abstract
A high flotation forklift with six degrees of freedom for movement of the fork assembly is provided. All of the movements to the fork assembly can be done while the forklift itself remains stationary. In addition to the conventional up-down movement, side-side movement, and front-back tilt, the present forklift provides for forward and backward fork movement, left-right yaw and side-to-side tilting while the forklift itself remains stationary. This allows for exact placement of any item, and is especially suited for placement of turf trays.

- a mast assembly connected to the frame, with a fork assembly connected thereto, the mast assembly being connected to the frame by a mast support assembly that allows forward and backward movement of the fork assembly, side-to-side tilting of the fork assembly, and yawing of the fork assembly relative to the frame.
