Dressta NA has introduced the TD20M Extra crawler dozer, which features big tractor performance coupled with ease of transportation.

The new series is available in three track versions: standard, long track (LT) and low ground pressure (LGP). These machines feature the fuel efficient Tier III Cummins engine to meet lower emission requirements. This powerful electronic control engine has an 8.3-L displacement. It delivers 240 net hp (179 kW), an increase of 15 hp (11 kW) over the previous “H” series model. Maximum torque is now 870 ft.-lbs. (1,180 Nm). An air grid heater comes standard to aid in cold weather starting.

The TD20M Extra utilizes a new cooling module with replaceable sections consisting of a charge air cooler (CAC), transmission oil cooler, radiator, and hydraulic oil/fan drive oil cooler.

The TD20M Extra has a hydraulically driven, suction type, variable speed fan located between the radiator and the front engine grill for ease of service and greatly reduced abrasion to the cooling module by eliminating sand and other debris from being picked up by the fan blades and blasted against the radiator.

Operating the TD20M Extra is easy with the introduction of a left hand, single lever joystick control. The joystick replaces two left hand steering levers and one gearshift lever used on the previous model. The transmission allows the operator to pre-select travel speed and down shift functions from the joystick.

Great efforts have been made to eliminate or greatly reduce the need for on-board computer control and electronic systems. The engine does not require a computer to diagnose problems. The TD20M Extra is a relatively easy tractor to troubleshoot and repair, according to the manufacturer.

Several blade options are available from Dressta: a new 11.1 cu. yd. (8.45 cu m) full-U blade, an increased capacity semi-U blade 9.2 cu. yd. (7.04 cu m) and an angle blade — “C” frame combination of 5.1 cu. yd. (3.88 cu m) for the standard and long track versions of the TD20M Extra. The straight blade has a 7.9-cu.-yd. (6.03 cu m) capacity and is used on the LGP version.

Winches and rippers are available. The multi-shank ripper penetration depth has been increased to 27.6 in. (70 cm).

The standard version of the TD20M Extra has an operating weight of 52,139 lbs. (23,650 kg). The operating weight of the LT version is 53,373 lbs. (24,210 kg) and the LGP version is 54,410 lbs. (24,680 kg).
