PRODUCT DETAILS
Description
The RTD Rough Terrain Series is built for demanding outdoor jobs where conditions are unpredictable. It runs on a dependable diesel engine and uses air pneumatic tires that grip well on dirt, gravel, and uneven ground. A Shimadzu hydraulic pump paired with Continental hosing gives the hydraulics a steady, confident feel, and the clear view mast helps operators stay aware of their surroundings while handling heavy loads.
Each unit comes equipped with bright LED lighting, a high-visibility strobe, and 48 inch forks. Inside the operator area, the truck includes a comfortable seat, a USB power port, and an LCD display that keeps key systems easy to monitor. Standard features like the side shifter and 3 way hydraulics help the truck handle rough conditions and heavy use without slowing down.
