Abstract

The specification discloses a lift for a tractor having a threepoint hitch and comprising a bed having a ramped shaped rear end structure, forward end structure extending upward from the forward end of the bed and side members connected to opposite edges of the bed and to the forward end structure whereby the tops of the side members slope downward from the top of the forward end toward the bed at the rear end of the lift. A carrier frame is provided to be connected to the three-point hitch of the tractor and for holding the lift in a lifting or hauling position or for allowing the rear end of the lift to swing downward for dumping purposes. In addition, there is provided a winch comprising a post which is adapted to be held by the lift on the inside thereof and which has an outward extending reel arm which may be located in different angular positions relative to the post of the winch. Also provided are two right triangular shaped sides adapted to be connected to the sloping tops of the side members to form a box-like lift which also includes a gate adapted to be secured to the rear end thereof.

Claims

1. A lift for a tractor having a three-point hitch connected to its rear end and including a central linkage and two spaced linkages, the latter of which are operated by a hydraulic system so as to raise or lower the two spaced linkages, said lift comprising:

a bed having a forward end and a rear end, said bed having a ramped shaped rear end sloping from the top downward to the bottom side of said bed, forward end structure extending upward from the forward end of said bed, side members connected to opposite side edges of said bed and to said forward end structure whereby the tops of said side members slope downwardly from the top of the forward end toward the bed at the rear end of said lift, a carrier frame comprising two arms having a cross member connected to first ends thereof, the opposite ends of said arms being pivotally connected to the lower forward end of said lift, means for connecting said carrier frame to the three-point hitch of the tractor, means for detachably connecting the upper end of said carrier frame to the upper forward end of said lift to allow said lift to be secured to both the top and bottom ends of said carrier frame or to allow the rear end of said lift to swing downward when the upper forward end of said lift is released from the upper end of said carrier frame, a blade secured to the lower forward end of said lift and projecting downward below said bed for use for grading purposes, winch holding means for securing a winch to the forward end of said lift, a winch, said winch holding means being adapted to secure the winch on the inside of said lift, said winch comprising;

a post adapted to be held by said winch holding means in a vertical position, an arm having a first end pivotally coupled to the upper end of said post and a free end for holding a reel, and means for securing said winch arm in different angular positions relative to said post from a range which extends from a position wherein said winch arm extends upward forming an obtuse angle relative to said post to a position wherein said winch arm extends downward forming an acute angle relative to said post, right angled triangular shaped side members adapted to have their sloping edges coupled to the top sloping edges of said first side members to form a box-like lift, and rear gate means adapted to be held by the rear ends of said triangular shaped side members.
