KX042-5
THE 4-TON COMPACT EXCAVATOR WITH LOW EMISSIONS
The ecological and high-performance reference in its category
The Kubota KX042-5 is the most environmentally friendly 4-ton compact excavator in its range. Its modern design and advanced technologies combine performance, reliability, and productivity on all types of job sites.
Equipped with the Kubota Stage V diesel engine with an improved particulate filter (DPF), it ensures reduced maintenance, optimised fuel consumption, and minimal emissions — ideal for professionals concerned with energy efficiency and environmental protection.
ENGINE POWER AND RELIABILITY
HIGH-PERFORMANCE AND INTELLIGENT HYDRAULICS
The load-sensing hydraulic system ensures smooth and precise response, even during complex operations. With a flow rate of 110 l/min, the machine delivers high digging force, optimising productivity. Adjustable auxiliary circuits allow flow adaptation to various tools, while the direct return line to the hydraulic tank activates automatically in breaker mode, simplifying use and reducing handling.
VERSATILITY ON ALL TERRAINS
The KX042-5 stands out for its great versatility. Its two travel speeds with automatic downshift, floating blade, and boom offset (70° left / 55° right) allow it to adapt to a variety of tasks: digging, levelling, lifting, or using hydraulic attachments. Lifting capacities compliant with ISO standards ensure optimal safety, even in challenging conditions.
OPTIMISED PERFORMANCE AND INCREASED PRODUCTIVITY
Thanks to the ESS (Engine Speed Sensing) system, engine power is fully utilised, providing higher hydraulic flow and increased efficiency. Automatic idling reduces fuel consumption and emissions, while Engine Auto Stop is standard, and LED work lights with timer enhance safety at the end of the day. All these innovations boost productivity while reducing operating costs.
EXCEPTIONAL OPERATOR COMFORT
The spacious and ergonomic cab provides a pleasant working environment, with more legroom and reduced noise at 72 dB. Depending on the version, the operator benefits from an air-suspension seat and air conditioning, ensuring optimal comfort even during long days. Modern features such as Bluetooth radio, USB charger, and phone holder enhance convenience and operator well-being.
The Kubota Tracking System is standard for precise machine monitoring.
ENHANCED SAFETY AND IMPROVED VISIBILITY
The KX042-5 incorporates numerous safety features: ROPS structure, high-visibility orange seat belt with alarm, safety valves on boom and arm, and Kubota anti-theft system. The 20% larger glass area improves visibility, complemented by the optional rear camera. Tie-down rings facilitate safe transport, while the green beacon predisposition allows remote seat belt monitoring.
