Abstract
A bale loader comprises a pair of arms pivoted to a wheeled frame and movable vertically. The arms carry, at their outer ends, a platform which is pivoted to the arms and movable between an upright position to a position parallel with the arms. The platform carries a pair of pivoted tynes which, when the platform is moved to the upright position, extend along the ground to engage beneath a bale. Hydraulic cylinders acting between the platform and the frame causes pivotal movement of the platform to lift the bale and a further cylinder lifts the platform and arms about the pivotal attachment to the frame whereby the bale is discharged to a feeder or the like. A movable carriage on the arms assists in discharge of the bale from the platform.

A bale loader
- comprising a pair of support arms each pivotally mounted at one end to a wheeled frame, said support arms being movable substantially vertically, means to restrict downward movement of said support arms, a loader platform pivotally mounted to and carried by the other ends of said support arms, said loader platform being movable between a first position and a second position, two or more tynes mounted to said loader platform to extend therefrom at a predetermined angle at least when said loader platform is in said first position, and actuating means operable to move the platform between the first and second positions and to move the arms and platform relative to the frame, wherein said arms carry a carriage movable therealong from a position adjacent the loader platform in its said second position towards said frame, and
- wherein a flexible line or chain extends between said carriage and said frame, said line or chain being of a length such that upward movement of the arms causes the line or chain to become tensioned.
