An elongated trailer-type vehicle is provided for pulling behind a prime mover such as a lawn tractor. The vehicle includes an elongated frame having vertically adjustable hitch structure at its forward end for releasable hitching behind a lawn tractor and downwardly extendible and upwardly retractable ground engaging support wheels for decreasing and increasing, respectively, the elevation of the frame above the ground surface upon which the wheels rest. The frame additionally includes front and rear depending spring tine assemblies forward and rearward of the wheels and the tine assemblies each include a plurality of depending tines spaced transversely of the frame. By raising and lowering the wheels relative to the frame, the spring tines may be adjusted relative to the lawn surface over which the wheels of the trailer move and adjustment of the hitch structure relative to the front of the frame in connection with vertical adjustment of the frame wheels may incline the frame either forwardly and downwardly or forwardly and upwardly relative to the horizontal. Inasmuch as the tine assemblies are dependedly supported from the frame forward and rearward of the wheels, either the front tine assembly, the rear tine assembly or both tine assemblies may be engaged with the ground with equal or unequal forces.
