Four new models build on the success of the popular F2-Series to deliver improved performance and fuel efficiency
CATERPILLAR are introducing four new backhoe loader models that build on the success of the Cat F2-Series backhoe loaders. The new line consists of the Cat 428, 432, 434 and the 444 models, replacing the 428F2, 432F2, 434F2 and the 444F2 machines respectively.
The new loaders offer similar model platforms throughout the line to deliver component commonality and operating similarities throughout range. The machines will also display the new Cat trade dress and nomenclature, which removes model suffixes.
A redesigned operator control system incorporates analogue machine gauges with a colour LCD information display that is soft-key controlled for simple navigation. Informational icon pop-ups offer quick navigation between operating modes, whilst full text diagnostic descriptions simplify machine troubleshooting and maintenance.
The new series’ enhanced security system disables the engine, transmission and hydraulic system until a valid passcode is entered via the LCD operator control screen.
Optional pilot controls are available on the 428 and 434, whilst new seat-mounted controls that provide the operator with more comfort and control are now standard on the 432 and the 444.
All four new models are powered by the Cat C3.6 engine, which delivers up to 10% improved fuel economy compared with the F2-Series engine and meets EU Stage V emission standards thanks to a service-free Selective Catalytic Reduction (SCR) emission solution with diesel exhaust fluid (DEF) and diesel particulate filter (DPF).
Selectable power management modes offer the operator a choice of both Economy and Standard for good engine performance and increased fuel savings, or Standard Plus to boost machine performance by maximizing backhoe implement speeds.
A new powershift transmission is available as an option on the 428 and 434 and fitted as standard on the 432, allowing easier on-the-go gear shifting for the operator. The 444 will continue to be fitted with a fully automatic transmission as standard.
All models in the new backhoe loader line feature standard four-wheel drive with rear differential lock for improved traction in poor ground conditions, and all feature adjustable auxiliary hydraulic flow to the backhoe, so machine hydraulics can be fine-tuned to meet the operating specifications of attachments.
To increase machine utilization, the new Cat line can be equipped from the factory (or as a field-installed kit) with optional Integrated Tool carrier couplers for fast work-tool changes. The new loaders are also compatible with F2-Series attachments.
New boom cylinders are available as an option on the 428 and the 434, providing up to 25% more boom lift capability to enhance operating performance.
Offering remote data monitoring through VisionLink, the latest Cat Product Link comes standard on all four new models to maximize machine uptime. Customers can customize machine operating data such as fuel usage, payload summaries, scheduled service reminders and fault code alerts, to meet specific needs for improved fleet management.
Meanwhile, new seat-mounted controls on the 432 and 444 stay with the operator when turning the seat to control loader and backhoe functions for more ergonomic and comfortable operation. This arrangement also permits Dual mode, which offers more efficient machine repositioning and also allows the operator to sit at an offset angle while controlling the machine for improved visibility.
For the first time on a Cat backhoe loader, a new, optional, touch-screen LCD display allows the operator to interact with machine to quickly change key operating functions such as pattern control and hydraulic control settings.
The new 428, 432, 434 and 444 backhoe loaders will be available from May 2020.
