Tractor T-25A - technical characteristics
Tractor T-25A. Universal wheeled tractor T-25A, traction class 0.6 t, is intended for pre-sowing soil cultivation, sowing, crop care, inter-row cultivation, work in gardens and vineyards, work on farms, transport work.
The main difference from each other in the configuration: on T-25A a cabin is installed, on the T-25A3 - a removable safety cage. A modification of the T-25A2 was produced.
Tractors T-25A and T-25A3 have a semi-frame design. The diesel engine D21A1 with a power of 25 hp is used for the drive. with electric start. In the rear part there is a dependent single-speed PTO shaft. Tractors are equipped with a separate-aggregate hydraulic system with an independent hydraulic pump drive.
The tractors were developed by a group of engineers under the leadership of VTZ General Designer V.V. Efros. They have the State Quality Mark.
Engine: Tractor T-25A diesel, four-stroke, two-cylinder, air-cooled, with direct fuel injection.
A large number of non-self-propelled attachments makes the T-25 and T-25A tractors truly versatile.
