Product information

The DTR75 gives you excellent surface coverage and gradeability with the help of the hydrostatic drum drive. Infinitely variable speed combined with Twin Vibration Technology delivers a smooth surface.

Maximize savings by minimizing the passes

The Twin Vibration Technology (TVT) on the DTR75 features vibratory elements in both drums. As both the drums are used actively for compaction the number of passes can be reduced saving time & money. TVT also ensures a uniformly compacted surface.


Engine shuts down automatically in case of low oil preventing breakdowns and repair costs.

Powerful hydrostatic drive

In order to deliver high operating speed, the Twin Vibration Technology is aided by hydrostatically driven drums. The hydrostatic drive known for its efficiency provides power to both drums helping the roller climb steep slopes with ease.

Great results

Continuously variable speed control ensures a smooth surface. Uniformly compacted surface is guaranteed thanks to the Twin Vibration Technology

Safe

Anti-crush mechanism on the operator handle and a parking brake ensures a safe operating environment.

All the operating functions are close to the operator to enable easy and fast operation.

Convenient

To minimize operator fatigue and allow long hours of stress free operation, the walk behind roller also features an electric start, vibration dampened steering handle and quiet vibration technology.

Practical

With a large water tank the equipment can be used for relatively longer periods without having to re-fill.
