In 2021, Kubota shows the 13.1tons of conventional tail excavator and 6 tons of non-tail excavator series.
Patrick Baker, the product manager from Kubota corporation said that:“According to the customers expectation, our new excavator model has more technologies, more quiet driver space and more comfortable functions. It can benefit for operators into reality.”

Kubota’s new KX057-5 conventional tail digger is powered by a 47.6 horsepower engine. Kubota said that KX057-5 replaced KX057-4, providing improved technology and sufficient cabin space in both the cockpit and the canopy model. This is the first time Kubota’s excavators have a keyless start option. The engine can be started with a four-digit code, and up to 10 user passwords can be set. The excavator is powered by a 47.6 horsepower engine, has a digging depth of 12 feet 9 inches, and a bucket digging force of 10,172 pounds. The 47.6 horsepower U55-5 tailless excavator has a digging depth of 11 feet 11 inches and a maximum dump height of 13 feet 2 inches.
To make the cab more comfortable, Kubota added dual-adjustable seats, increased head and foot room, and reduced noise levels. Moreover, Kubota installed a thicker floor and replaced the elevated frame with a felt ceiling. Thinner cab pillars and metal window sashes were also used. Similarly to KX057-5, U55-5 has an LCD screen and keyless entry. A rear view camera is optional.
Now, Kubota provides hydraulic quick couplings for the entire 3 to 4 ton excavator (including KX033, U35 and KX040). Kubota said the new coupling allows the operator to change the bucket in approximately 10-15 seconds while sitting in the cab. The customized control kit for excavators includes a dedicated hose kit and a spring-applied hydraulic release and locking mechanism, and the coupling is compatible with older buckets.
