A timber saw bed or trailer is a type of mobile platform used to transport and saw logs into lumber. It is typically made of durable materials such as steel or aluminium and can be attached to a truck or tractor to be transported to different locations. They are commonly used in the lumber industry, by professional loggers and sawyers, and in some rural areas.

A timber saw bed or trailer usually features a saw bed that is equipped with a sawmill, which is used to saw logs into lumber. The sawmill can be powered by a gas or electric motor and is used to cut the logs to the desired size and shape. The bed may also have a built-in conveyor belt to move the logs around, and it can be outfitted with a variety of tools and equipment to aid in the cutting process.

The saw bed can be customised to meet the specific needs of the sawyer and the logs being cut. It can be equipped with different types of saw blades, and it can be made to hold different size logs.
