Kubota is one of the few engine manufacturers left that produce engines from step 0, the casting level. The Engine Division continues to produce superb engines by successfully combining its '100 years plus ' history and experience in metal casting technology, with the latest production facilities. NC-controlled robots are installed in many lines to maintain high quality engine production, as well as to speed up and increase the overall production efficiency. Great variety of automatic measuring devices are installed along the engine production lines to ensure clean and stable emission levels. The ability to produce engines that are capable of clearing all emission regulations is the Division's driving force in producing advanced, high quality engines of the future.

Cylinder head machining and crankcase machining lines require high precision work. Kubota has invested much in highly sophisticated computer controlled robots to speed up the production of high quality products and increase the overall production efficiency.




Nearly 1/3 of all engine assembly work is automated. This includes 16 NC- controlled assembling robots, and 15 basic engine assembly machines for crankcases, crank gear, pistons, and connecting rods. Recognizing specifications by model, these state-of-the-art robots select correct parts, assemble and weigh engines.




Built in 1998 to speed up the production of high precision engine parts, this line is the perfect blend of years of metal casting experience and the latest technological advances. By computerizing the line, Kubota effectively speeded up the production of multi-item, large and small lots, as well as reducing both time and cost.
