Caterpillar rounds out its compact wheel loader lineup

Caterpillar's new 907H offers a skid-steer-loader-type coupler, an auxiliary hydraulic system, two-speed hydrostatic drive, standard differential locks in both axles, and a variety of other standard and optional features.

Caterpillar's new 907H features the most logical nomenclature for a compact wheel loader designed to fit between the company's 906H and 908H models. The new 70-net-hp (52-kW) machine is powered by a Tier-3-compliant Cat C3.4 engine and offers a variety of both standard and optional features that Cat says enhance the 907H's performance and versatility in a diversity of landscaping, industrial, and general-construction applications.

An hydraulically actuated skid-steer-loader-type coupler, which the 907H shares with the 906H and 908H, allows use of many of the hydro-mechanical work tools that customers presently have with other Cat loaders and skid steers, allowing the 907H to be easily integrated into existing small-equipment fleets.

Standard auxiliary hydraulics, proportional third-function valve, and continuous-flow capability provide a complete control package for work tools such as trenchers and stump grinders. The optional 33-gal/min (125-L/min) high-flow system handles demanding tools such as cold planers and snow blowers, for example.

Like its 906H and 908H counterparts, the new 907H features articulated steering for precise maneuvering and axle oscillation for positive traction in rough terrain. For added traction in poor underfoot conditions, differential locks (in both axles) can be engaged on the move to reduce wheel spin and tire wear. With parallel-lift Z-bar loader linkage, the fork-equipped 907H places loads surely and precisely, and when fitted with its 1.3-yd 3 (1.0-m3) bucket, the 907H works aggressively and has ample dump clearance.

All of the three operator stations available for the 907H—canopy, Comfort Cab, or Deluxe Cab—offer safety and comfort, says Cat. An optional air ride seat combined with low-effort steering and pilot controls reduce operator fatigue and provide convenient, intuitive operation. The multifunctional joystick provides basic lift and tilt functions, as well as controls for selecting travel direction, travel speed, third-function hydraulics, and continuous flow or for activating the differential lock. The 907H cab is 5 in (127 mm) higher than the 906H cab for increased visibility to work tools and the surrounding work area.

To encourage disciplined routine maintenance, the 907H has a high-opening engine hood and side service doors for ground-level access to all major components and service points. The articulating hydraulic-oil cooler gives ready access to the radiator, and both are easily cleaned. Cat says that vertical spin-on filters (engine oil, hydraulic, and fuel) are replaced quickly with no spillage, and S.O.S. valves and pressure taps are conveniently located in the engine compartment.

The 907H's capability to handle hydro-mechanical work tools is enhanced with an optional wiring harness that permits fourth-function control (broom angling, for instance). In addition, an available creeper feature, complete with hand throttle, allows the operator to easily maintain consistent, slow ground speed, while the work tool runs at high speed for efficient production.

An optional transmission that adds a two-range gearbox to the drivetrain provides travel speeds to 21.7 mph (35 km/h) and incorporates hydraulically actuated, oil-immersed disc brakes in the front axle. Available ride control cushions boom-cylinder movement during load-and-carry operations, resulting in a smoother ride for the operator and less material spillage.
