The T150 K tractor was the main teaching tool at JärvaJaani Vocational School no. 31. The tractor training class created by Helmut Vajakas in the Orina manor contains crosssections of the T150 engine and gearbox, from which the working principles of the technology were learned. This tractor found its place in front of Orina manor in JärvaJaani.

Information about the tractor

The T150K was developed based on the tracked tractor T150, which was introduced in 1970, and has been produced since 1972. The K in the designation stands for "koljosny" (Russian: колёсный: with wheels). It inherited the body and engine from the T150, a sixcylinder turbo diesel, whose power was increased from 150 to 165 horsepower at 2100 rpm. The rigid frame of the tracked tractor T150 was replaced in the T150K by a twopiece frame, whose connection joint is pivotable around the longitudinal and vertical axis and allows for hydraulic articulated steering. The maximum articulation angle is 30° in each direction. A twostroke engine is used for starting, which is started electrically and, in the event of battery failure, can also be started with a pull starter. The hot exhaust gases of the starter motor are used to preheat the engine oil and coolant. The tractor is known to be reliable, maintenancefriendly, and relatively comfortable for its time.
