Buhler Versatile HHT 435 – 575

In 2005, Buhler Versatile introduced a new HHT model range (High Horsepower Tractor). The lineup was significantly more robust than before: the weight had increased to 14 tons. For example, the main bearing at the pivot point was 60% larger than before. The HHT models were equipped with a 15-liter Cummins QSX engine that met Tier 3 requirements. The base transmission, like in the smaller models, was a mechanical 12+4. Additionally, model 435 was available with a 12+2 full powershift transmission. A new feature offered for all models was Caterpillar’s 16+4 full powershift, which included, among other things, gear automation and the ability to pre-select the gear while stationary that the automation would shift to when starting to move. For the first time, the top speed of the powershift was 40 km/h.

The standard hydraulic output was 208 liters, with an optional 303 liters. You could have up to eight hydraulic blocks. Electrically controlled valves were available as an option. No three-point hitch was available at all. The cab was new and wider than before. The cab was available in standard or Deluxe versions. The Deluxe featured, among other things, semi-active seat suspension, xenon work lights, and automatic climate control. Unlike competitors, the electrical system remained solely 12 volts.

From 2008 onward, the brand name was simply Versatile. In 2010, the most powerful model, the HHT 575, was introduced.
