SD12 Mini Excavator – Powerful, Flexible & Built for Professional Performance
The SENDEMACH SD12 is a 1.2-ton compact mini excavator engineered for construction contractors, rental businesses, landscapers, and agricultural users who need a reliable, versatile, and fuel-efficient machine. Powered by the Yanmar 3TNV70 diesel engine, the SD12 delivers exceptional performance, low noise, reduced emissions, and long service life.
Designed with a retractable (expandable) chassis, the SD12 easily adapts to narrow working spaces while providing increased stability when fully extended. The two-speed travel motor allows operators to switch between low-speed torque and high-speed mobility for faster jobsite movement.
Its reinforced boom, precise hydraulic system, and wide range of attachments make the SD12 the ideal micro excavator for tough jobs in tight areas.
