In 2010 the newest offspring of the Forterra series was the model 135 with a new engine Z 1605 with 136 hp (100 kW) power and a sixteen-valve cylinder head. The engines of the whole power range were homologated for Stage III. The new model series of Forterra tractors also distinguished itself with its interior design and equipment. A significant innovation was represented by the tilting bonnet of a brand new design. The style was close to the Proxima, with a square profile and identical circular headlights. The cab interior was distinguished with a new hydraulic control panel with covered control cables of hydraulic distributor.
