Product Details

Large excavators are too bulky for backyard gates, and cheap mini backhoe units lack the hydraulic power needed for real construction. The Derette RT20 fills the gap. As a premium mini crawler excavator, it combines the agility of a micro excavator with the digging force of a much larger machine. Whether you are trenching in a confined alley or grading a commercial landscape, the RT20 delivers hyundai excavator class precision without the massive footprint.

Four Core Technical Advantages
Tier-1 Heart — The Power of Kubota Headline: Why Settle for Less? Genuine Kubota D902 / Yanmar Engine. Content: At the core of this mini excavator digger machine lies the world-renowned Kubota D902 diesel engine. Fully compliant with EPA Tier 4 and Euro V standards, it provides the steady, high-torque output required for stubborn soil. Unlike generic excavator small digger models, Derette ensures your machine is ready for global export and local serviceability.
Narrow Access Mastery — Retractable Undercarriage Headline: The Micro Excavator That Fits Through a 1-Meter Gate. Content: Don't let tight fences stop your project. The RT20 features a hydraulic retractable chassis, allowing you to shrink the width to just 990mm. Once inside the job site, expand it to 1300mm for maximum stability. It’s the versatility of a mini backhoe with the specialized stability of a mini crawler excavator.
Zero-Tail Swing & Side Swing Boom Headline: Work Against the Wall with Confidence. Content: Residential landscaping often means working flush against foundations and fences.
