[Effect of the idea]

The present invention has the above configuration and has the following effects. (1) Equipped with a self-propelled cart and a sawmill installed on the self-propelled cart, the sawmill can be moved to any location such as a logging area in a mountain forest and sawn locally. Since the lumber can be processed at the felled area in this way, there is no need to transport the cut lumber, and only the processed products need to be transported, resulting in a significant reduction in the cost of transporting the lumber. In addition, if cuttings and waste wood are left in the forest, they will easily rot and be returned to the forest, which not only eliminates processing costs but is also effective in preserving and cultivating the forest. (2) When the feeder frame moves to the rearmost position, the front end is located behind the saw, and a part of the feeder frame hangs over the rear of the fixed machine frame, and when the feeder frame moves to the frontmost position, the rear end is located behind the saw. Since it is located in front of the saw and partially hangs over the front part of the fixing machine frame, the length of the fixing machine frame required for sawing can be shortened.
This makes it possible to shorten the overall length of the sawmill and provide a self-propelled sawmill that is convenient to maneuver.
