The TD-40R Extra is equipped with a Perkins 2806F engine, compliant with EPA Tier 4f / EU Stage IV emissions standards. It has a displacement of 18.1 L and delivers a gross horsepower of 429 kW (575 Hp) and a net horsepower of 397 kW (532 Hp) at 2000 rpm. The engine features a dry type air cleaner with an electronic service indicator and can operate on slopes up to 45°.

Cooling System:
The cooling system includes a suction-type variable-speed fan, hydraulically driven, with a coolant rating of -37 °C.

Hydraulics:
The machine uses an open-center hydraulic system with a fixed-displacement multi-pump vane type. The system relief pressure for blade lift and ripper is 17 MPa, and for blade tilt, it is 18.4 MPa. It is controlled by a single joystick lever.

Electrical System:
The electrical system operates at 24 V with four batteries providing a capacity of 960 CCA. It includes an alternator rated at 150 A and eight lights mounted on various parts of the machine.

Operator Station:
The operator station is equipped with ROPS and FOPS for safety, an oscillation-type suspension, and a comfortable air suspension seat with adjustable features.

Undercarriage:
The undercarriage features large, sealed, and lubricated track links and rollers for durability. The track gauge is 2500 mm, and the track shoe width is 610 mm.

Machine Dimensions:
The overall height with FOPS Cab is 4,060 mm, and the length with blade and ripper is up to 10.350 m. The ground clearance is 600 mm.

Serviceability:
The machine has various refill capacities, including a fuel tank of 1270 L and a hydraulic reservoir of 184 L.

Blade Specifications:
The TD-40R Extra offers different blade types with capacities ranging from 18.6 m³ to 39.8 m³. The blade height and width vary depending on the type.

Ripper Specifications:
The ripper is a parallelogram type with hydraulic pitch adjustment, available in single-shank and multi-shank configurations.

Operating Weights:
The base weight with standard equipment is 67,850 kg, with optional components available for additional weight.

Powertrain:
The powertrain includes a single-stage torque converter and a modular power shift transmission with 6 forward and 6 reverse speeds. The steering system provides gradual turns while maintaining full power.

Standard Equipment:
Includes a comprehensive list of features such as air conditioning, electronic monitoring systems, and various safety and operational controls.

Optional Equipment:
Offers additional features like different blade types, rear-mounted equipment, and enhanced operator environment options.

Additional Information:
The document emphasizes the importance of consulting the operator's manual and highlights the customization options available through Dressta's engineering team.
