Abstract:
1. An improved trailer, comprising: (a) a frame including two generally parallel, generally horizontal spaced apart side members, (b) a wheel assembly mounted on each of the two side members of the frame, each wheel assembly including an arm having a proximate end and a distal end, each arm pivotably mounted to the side member at the proximate end of the arm and each arm having a wheel rotatably mounted to the distal end thereof, (c) an actuator connecting between each side member of the frame and the arm of each wheel assembly, the actuators adapted and controlled in order to extend and retract in unison in order to cause the wheel assemblies to move in unison between a first retracted position and a second extended position, the first retracted position characterized by proximity of each wheel of each wheel assembly to the frame side member, the second extended position characterized by spaced separation of each wheel of each wheel assembly from the frame side member thereby causing the frame to be supported in a raised position, (d) the frame having attachment means for clamping onto and holding a livestock implement, whereby the trailer may be extended into a fully extended position, rolled over a livestock implement, slightly retracted to come into proximity with the livestock implement for engaging the attachment means to the livestock implement and then fully extended in order to lift the livestock implement to a height above the ground sufficient for transporting the livestock implement with the trailer and whereby the trailer may be pulled to transport the livestock implement to a location and retracted to place the livestock implement on the ground prior to use of the livestock implement and further whereby the trailer may be pulled to transport the livestock implement to a location and retracted to place the livestock implement on the ground, disengaged from the livestock implement, raised and rolled away from the livestock implement prior to use of the livestock implement.
