Case is launching its new 400 Series 3 line of compact track loaders, which feature U.S. EPA Tier 3 certified engines and a new cab with improved visibility and ergonomics. All four new models—420CT, 440CT, 445CT, and 450CT—include pilot controls as a standard feature.
The 420CT and 445CT models are powered by Case 3.2-L turbocharged engines, while the 440CT and 450CT Series 3 models are powered by a 4.5-L turbocharged Case engine. For easier startup in colder temperatures, the loaders include a grid heater as well as a larger, 1125 CCA battery that is 32% more powerful than in previous models. With the new batteries, Case has tested all four 400 Series 3 compact track loaders and found them to start unaided at -10°F (-23°C).
Case uses a dozer-style undercarriage for its compact track loaders, noting that the design relies on fewer moving parts than in competitive designs. An angled track frame and material scrapers help to reduce the amount of mud and material buildup, and the steel-embedded tracks roll on rubber instead of steel, helping to preserve track life and provide a smoother ride. The Rexroth drive motor uses an oversized bearing in line with the drive sprocket to make it easier to keep material out, while increasing component life.
“Case compact track loaders require less maintenance and are easier to maintain compared to suspension track systems because we use a rigid track frame with no moving parts,” said Jim Hughes, Marketing Manager, Case Construction Equipment.
A sealed and oil-lubricated roller and idler system helps to further reduce exposure to debris and moisture. Duo cone face seals are designed to last longer than ordinary seals, thus reducing maintenance costs, and dozer-style triple flange rollers with an inner diameter flange positioned between the track tabs help to prevent de-tracking on slopes.
Daily servicing is streamlined with checkpoints such as hydraulic and coolant sight gauges, engine oil dipstick, and air filter grouped into a single location at the back of the machine. The loaders also feature an easy-tilt ROPS (rollover protective structure) for quick access to key components when major service is required.
Pilot controls, now standard for the four Case compact track loaders, are available from the factory in either H or ISO patterns. With the H pattern, independent control of the ground drives allows the operator to position the machine with greater precision, which can be helpful when performing tasks such as fine grading.
With the ISO pattern, both drive functions are in the left controller, and the loader arm/bucket functions are in the right controller. This allows for one-handed operation and is prevalent on non-Case machines.
New cabs available for the Series 3 compact track loaders feature increased headroom, a suspension seat, and a new cushioned lap bar with arm rest and ergonomically designed control handles. The front glass area is larger than in predecessor models—a 20% increase for the 445CT and 450CT, and an 80% increase for the 420CT and 440CT. Exterior side lighting and a foot throttle are now standard on all models, and a pressurized cab and air conditioning are available options.
Other available options for the new compact track loaders include proportional auxiliary controls, a detent switch that does not have to be held down for two-speed operation, optional removable cab windows, solid flex tires, and a deluxe cloth suspension seat with heater and lumbar support.
