An apparatus for attachment to a tractor the apparatus comprising a primary implement and at a first end, connections suitable to connect to the three point linkage of the tractor and at a second end, connections suitable to connect to the three point hitch points of a secondary implement.

A vehicle tow device for wheeled containers preferably includes a hitch insert, an upright member, at least one support member and at least two retention members. The hitch insert preferably includes a U-shaped cross. The upright member preferably includes a U-shaped cross section and a horizontal flange extending from a top thereof. The hitch insert is attached to the upright member. Each support member includes a top flange and a side flange. Each support member is pivotally engaged with the horizontal flange. Each retention member includes a first retention flange and a second retention flange. Preferably, a bottom of the second retention flange is bent upward, substantially perpendicular to itself to form a non-pivot flange. A top of the second retention flange is bent to an acute angle to form a retention flange. The second retention flange is attached to a side flange of the support member.

A trailer having a framework configured for selectively switching between a wheel-based towing mechanism and a ski-based towing mechanism and wherein the trailer framework is lightweight and configured for supporting an enclosed trailer that may be constructed of lightweight composite paneling. The trailer framework can also be used with a pivotable and removable tow-bar where the tow-bar is configured with a plurality of pivotable attachment points for pivotably securing to the framework. The tow-bar is also connectable to any tow-vehicle and can be removed from the tow-vehicle and the trailer framework when not in use, or can be pivoted upwardly about the trailer framework for storage.

A towing system comprises a bar, a first attachment device arranged at a first end of the bar, the first attachment device being able to attach the towing system to a towing vehicle, a second attachment device arranged at a second end of the bar, the second attachment device being able to attach the towing system to a travelling machine to be towed, the second attachment device comprising a fork able to hold at least one wheel of the travelling machine, the fork having two longitudinal members between which at least one wheel of the travelling machine is able to be received, a separation device able to modify the spacing between the two longitudinal members and a holding device able to hold the wheel between the two longitudinal members.

A trolley that couples to a tow saddle is provided. The trolley includes an upper plate and a lower plate. The upper and lower plate are secured against a rear portion of a tow saddle. One or more support bars are coupled to the upper plate. The bars provide structural support for the upper plate and deflect a chain that transits apertures in the upper plate.
