Modular design Just like the D51. One of the design goals behind the creation of the D31/D37 was to manufacture a more durable machine. [. . . ] To minimize Long track-on-ground Long track-on-ground improves machine stability and grading/dozing performance. noise and vibration, the engine is iso-mounted to the main frame. * ISO9249 Photo may include optional equipment. Adjustment-free parking disc brake An adjustment-free spring-applied hydraulic release wet parking brake is located in each final drive. Dynamic HST Photo may include optional equipment. Hydrostatic Transmission (HST) control system Adjustable pitch PAT blade Blade pitch angle can be easily adjusted by changing the length of the pitch rod on the top of the blade. This enables maximum job efficiency in various material and ground conditions. The HST controller monitors engine output and work equipment/travel load. It controls HST pump and motor displacement to provide the optimum speed and drawbar pull. Power to both tracks during turns and counter-rotation makes the D31/D37 extremely maneuverable. braking is used until the machine stops moving, then the parking brake engages, minimizing wear. New monitor with self-diagnostic function The monitor system provides critical information about the machine. It provides operating condition status and notifies the operator with a lamp and buzzer when an abnormality occurs. In addition, fault codes are indicated to aid troubleshooting and help reduce machine downtime. Komtrax adds a valuable dimension to troubleshooting and maintenance. Easy engine oil drain Changing the engine oil is easy with a strategically mounted access cover. There is no need to crawl under the machine to drain the engine oil. Hydraulically-driven cooling fan The engine cooling fan rotation speed and direction is electronically controlled. The fan rotation speed depends on engine coolant and hydraulic oil temperatures; the higher the temperature, the higher the fan speed. This system increases fuel efficiency, reduces operating noise levels, and requires less horsepower than a belt-driven fan. Additionally, cool ambient air is pulled in through perforations in the rear access doors adding to its cooling efficiency. Towing hitch The optional hitch extends past the track to allow maximum angle when towing.
