Equipment

New Machines, Original DNA – The first Cat® backhoe loader hit the road in 1985. The machine was co-developed by a team of designers in Illinois, U.S. and a manufacturing team in Desford, UK. The machines are still designed by experts to meet the needs of today’s operators. Every model provides reliability, power and a top-quality operator environment to see you through the toughest projects. The latest backhoe loader range is crafted from 35 years of passion, expertise and experience.

C3.6 STAGE V ENGINE

The Cat® C3.6 engine meets EU Stage V emission standards while delivering up to a 10% fuel efficiency improvement compared to the previous model. The aftertreatment system is completely maintenance free with Selective Catalytic Reduction (SCR), Diesel Exhaust Fluid (DEF) and fit for life Diesel Particulate Filter (DPF) system.

IMPROVED OPERATOR COMFORT

Hoe Pilot controls are available as an option on the 434. These are mounted on fully adjustable pods that the operator can position to their preference. These controls increase operator comfort by having them located in the most ergonomic position as well as being easier and smoother to operate than the standard mechanical controls. The loader control remains mechanical.

GREATER LIFTING PERFORMANCE

The option of a larger boom cylinder will give greater lifting performance on the back of the 434 machine.The option is available with either mechanical or pilot controls.

POWERSHIFT TRANSMISSION OPTION

The 434 comes as standard with the floor-mounted standard shifter. Upgrade to the powershift transmission for quick and efficient gear changes. Also available are the Autoshift transmission for automoatic gear changes or a Lock-Up Torque Converter (LUTC) for improved fuel efficiency while roading.

INTERACTIVE DISPLAY SCREENS

The choice of either a soft key or touchscreen display screen gives the operator information at the touch of their fingertips. Optional Machine Security Software is embedded into the display screen as well as notifications on service intervals.

POWERFUL AND EFFICIENT HYDRAULICS

The load sensing hydraulic system coupled with a variable displacement piston pump deliver powerful hydraulics when the operator really requires it.

POWER MANAGEMENT MODES

Choose between three engine options to help tailor machine performance to the application. Standard Mode or Standard Plus gives more speed and power when required. Eco Mode, (optional with pilot or powershift transmission) greatly improves fuel efficiency.

PRODUCT LINK™

Product Link™ comes as standard on the Cat backhoe loader. Many features exist through Product Link including fuel burn and location allowing the owner to access all data to help increase productivity while reducing costs.
