Develon has unveiled its new DX27Z-7 mini-excavator which introduces for the first time a zero tail swing design, making it suitable for tight spaces. The 2.8 tonne model was the first of the company’s next generation mini-excavator range with a new shared global styling. The zero tail swing design of the DX27Z-7 makes it ideal for work in confined spaces on construction, landscaping and utility projects.
The DX27Z-7 is powered by the Develon D17 Stage V compliant diesel engine providing 18.4 kW (24.7 HP) of power at 2400 RPM. As a result, this model offers the highest power and torque in its respective class and covers a wide range of applications including heavy duty work.
A novel platform design featuring a new upper structure has increased durability/robustness and this is complemented by a larger working range than other equivalent machines on the market, coupled with higher lifting capacities and digging forces.

The DX27Z-7 offers a high hydraulic flow of 58 l/min which enhances work with attachments. A new EPPR valve is incorporated for two-way and optional rotating functions, that provides the operator with 10-step proportional control of the hydraulic flow rate via the thumbwheel joystick.
In all Develon next generation mini-excavators, newly designed cast counterweights ensure excellent machine balance and stability when working. In the DX27Z-7, a long arm option is also available with a 60 kg additional counterweight included.
As well as offering the best performance, versatility, durability and ease of maintenance in its class, the DX27Z-7 features a new larger, roomier cab, providing excellent operator comfort and controllability.
The DX27Z-7 is also packed with a host of innovative features. Nowhere is this more evident than in the.new high comfort cab, which has a full glass entry door to maximize operator visibility on this side of the machine from inside the cab. The high luminance LED work lamps on the cab further enhance visibility and additional LED lamps are also available as an option.
Key features of the new cab include an enhanced heating/HVAC system (AC is optional), DAB Audio, 5.7 inch screen and mechanical suspension fabric seat with heating.
The enhanced heating/HVAC system is the best on the market, providing more nozzles to direct warming and cooling air, including both front and rear pillar nozzles that together help to improve the system performance. Larger nozzles are also used to ensure direct and sufficient airflow for operators and manual adjustment of the opening/closing of the nozzles is also possible.
The DX27Z-7 incorporates a new dozer blade providing both a higher dozer lifting height and dozer digging depth than other machines on the market. The machine also has a new dozer blade control lever.
Using the dozer lever, the operator can select between low and high speed for the levelling blade hydraulics. Travel speed can also be selected by using the travel selector button on the dozer lever. When hydraulic oil pressure rises due to going up a slope while driving in the high speed mode, the travel speed auto-shift valve automatically resets the travel speed to low, to enhance the operator’s driving convenience and to reduce machine stress.
The boom swing angle and swing radius is better than or equal to other machines in this class. Visibility and workability are improved by increasing the bucket protrusion distance beyond the tracks. Placing the boom swing cylinder on the left hand side of cab allows the operator to work right up against walls and other structures on the right hand side of the machines. The fuel tank and boom swing cylinder have been positioned at the base of the cab, with the MCV now on the right side of the machine, improving visibility for maintaining and working on the MCV
