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.
