The mini wheel excavator is equipped with steering, power and work modes to help operators customize their performance to move and work within confined spaces. An innovative articulated boom and boom swing also help in tight spaces, providing additional pivot points, which enhances the working range, lifting capacity and digging force.
DX100W-7 has a 1.35-ton counterweight for improved digging and lifting performance. It also features a large hydraulic capacity, so it can effortlessly hoist and maneuver heavy loads while minimizing fuel consumption. Operators can choose from four work modes and four power modes to customize power and performance to the task at hand.
For improved control, the standard 1-way/2-way switch lever provides hydraulic flow that is activated through the joystick, not the pedal. One-way hydraulic flow is ideal when using such attachments as hydraulic breakers and plate compactors, whereas two-way hydraulic flow is best when using hydraulic thumbs (clamps), rippers and grapples.
The machine is equipped with a large boom that allows the mini wheel excavator to reach farther and access hard-to-reach areas. It also helps operators achieve greater digging depth and height so they can tackle deeper excavation projects or reach higher elevations when loading or dumping materials.
In addition, the mini wheel excavator has a standard hydrostatic system that uses hydraulic fluid to ensure seamless, responsive operation for better control. By transferring power directly from the engine to the excavator wheels, the system provides high torque even at low speeds, enhancing maneuverability and efficiency.
For enhanced visibility, DX100W-7 comes standard with a high-illumination LED light system, including one additional working lamp. Also, standard is the around-view monitor (AVM) camera system with a 270-degree view, equipped with ultrasonic sensors. The sensors increase safety on the job site by alerting operators of nearby objects as they back up the machine.
DTL35 compact track loader
DEVELON also introduced the new DTL35 compact track loader, the company’s first machine of its type, which can easily complete tasks like pushing, lifting, digging and land clearing.

The DTL35 compact track loader is equipped with a reliable D34 engine, which is also used in the DEVELON DD100 dozer. The engine helps minimize downtime, reduce maintenance costs, and ensure consistent performance in demanding work conditions.
Two rubber track patterns are available; both include a wide and narrow version. A wide multi-bar track comes standard, while a block pattern is optional. The wide multi-bar tracks offer increased contact with surfaces for better traction. This design increases stability and reduces vibration and the risk of slippage.
Ride control reduces shocks and vibrations, which enhances stability for the bucket and minimizes spillage when the compact track loader navigates rough terrain while carrying full loads. The auto return to dig automatically returns the arms to the lowered position, saving operators time while delivering a more consistent digging depth.
The standard 2-speed travel feature allows the compact track loader to operate at the best speed for the job. The higher speed (up to 9.2 miles per hour) is for traveling longer distances or quickly moving between job sites; the lower speed (up to 6.1 miles per hour) for stabilizing the machine during more precise and controlled movements in challenging conditions.
The reversible fan protects against dust and debris, keeping the compact track loader’s engine cleaner and cooler to help extend the life of the machine. The rearview (backup) camera provides an additional view, allowing operators to easily see behind the machine.
To help maintain the loader’s stability, a self-leveling feature automatically adjusts the attachment to remain level as the arms are raised or lowered. This stability is crucial for ensuring safe operation.
The bucket shake feature helps shake loose or release materials stuck to the attachment and facilitates quick and efficient dumping without the need to stop and manually clean the machine.
