A trailer of the type for use in supporting machines such as snowmobiles, lawn and garden tractors and the like. The trailer includes a frame supported for pivotal movement about the axis of the trailer axle such that the rearward end of the trailer can move toward the ground such that the bed of the trailer is inclined to thereby facilitate loading of a machine onto the trailer. The trailer also includes a draw bar having a forward end including a hitch device adapted to be connected to a vehicle, and the rearward end of the draw bar is pivotably connected to the trailer frame and bed forwardly of the vehicle axle. A lever assembly is also provided for mechanically lifting the forward end of the trailer bed with respect to the draw bar so as to cause the rearward end of the trailer to move downwardly toward the ground to a loading position.
