Abstract: A retro-fittable mobility kit enables one person alone to conveniently move a heavy machine such as wood or metal-working machine of the type that is originally designed to remain in a fixed location, and that normally would require special handling equipment and/or several persons available, should it become necessary to move the machine. The mobility kit includes (a) a pair of fixed wheel assemblies to be mounted on each side toward a first end of the machine, each having a wheel partially enclosed in a metal bracket, and (b) one front swivel caster wheel assembly that mounts onto a central location at the second end of the machine. A preferred embodiment provides an adjustable clamping system on each of the three assemblies for attachment onto a structural member such as bottom framework of the machine, a fixed wheel assembly on each the side toward the first end, and a swivel caster in a central location at the second end.
