Mini Excavator GT JAPAN1000J
Crawler Mini Excavator
The GT JAPAN1000J mini excavator, in its new and improved version, is a compact machine weighing 1035 kg, designed for precise excavation work in confined spaces. Thanks to its adjustable width of 750–950 mm, it is ideal for narrow passages, private properties, gardens, and urban environments. Perfect for excavation work for installations, foundations, fences, and for clearing and leveling tasks.

Kubota D722 engine – reliability and power

The machine is equipped with a 3-cylinder Kubota D722 diesel engine with an output of 10.2 kW at 2500 rpm. This engine is known for its smooth operation, low fuel consumption, and high durability. This ensures that the mini excavator delivers stable and efficient performance, even under heavy use.

Advanced hydraulic system

The GT JAPAN1000J is equipped with a double gear pump with a capacity of 25 l/min and a Load Sensing valve system, which ensures smooth, precise, and energy-efficient operation. The working pressure of 16 MPa guarantees sufficient power for demanding tasks, while the maximum drawbar pull of 19 kN ensures good mobility on difficult terrain.

Precision and ease of operation

The mini excavator features ergonomic joysticks that enable intuitive and precise control. The swivel boom (54° to the left / 59° to the right) significantly facilitates working along walls and obstacles, while the extendable tracks provide extra stability and adaptation to different working conditions.

Compact dimensions and mobility

The total length of the machine is 3005 mm, the height is 2160 mm, and the width is adjustable from 750 to 950 mm. The turning radius at the rear is only 510 mm, which allows operation in very confined spaces. The ground clearance at the rear is 380 mm and the minimum ground clearance is 140 mm, which facilitates driving on uneven terrain. The tracks with a width of 180 mm and a length of 1330 mm provide stability and good grip.
