Machine roller kits include four machine rollers and two steering bars for moving large loads and equipment. They also come with a lockable steel case for securely storing the rollers and steering bars when not in use.

Front- and rear-support machine rollers are placed under the front or back side of a piece of heavy equipment to move it. One front roller is typically paired with one rear roller when moving equipment, but any combination of front- and rear-support rollers can be used as long as they have the same deck height. Front-support machine rollers have a tow eye for attaching optional steering bars, and they have a swivel platform that allows equipment on the rollers to turn. Rear-support machine rollers have a connection bar that can be adjusted to distribute weight and allow the rollers to fit under equipment with a range of widths. They have a fixed platform for straight-line movement.
