One of such universal machines is the tractor skidding TT-4M, details of which will be discussed in this article.

Purpose

This unit is truly unique and quality product of Soviet engineering, which refers to the fourth class. The main purpose of TT-4M is the timber large and of medium length to the warehouse from the forest, and also loading it on the platform or trains in the form of large blocks.

Production of the tractor took place on the Altai. In the series, this machine went to is far from us 1969. As the basis for the machine served fairly popular tractor TDT-75. It was upgraded that allowed to use more new parts, will greatly enhance performance.

Structural elements

TT-4M is equipped with a double cabin with seats located to the left of the engine. The driver of the tractor feels pretty comfortable in the workplace, since the cabin has opening wide open doors and Windows, and can also be heated.

The engine of the machine, in addition to impressive power, has optimum operation even in harsh climatic conditions, and because the tractor is often used in the Northern parts of Russia and Siberia.

The Bottom of the car has also been improved and have been applying a protective layer. This innovation has ensured the protection of individual parts and assemblies of the tractor from a very negative, abrasive and mechanical wear.

TT-4M was fitted with loading shield, and two-way winch with tractive effort of 122.3 kN. The thoughtful layout makes it possible to conveniently carry out the process of skidding, and loading. Maximum permissible load on the shield should not exceed six tonnes.

On the front wall of the tractor cab is the flap, equipped with devices to perform the required set of operations and quality controls of the machine itself. There are mechanisms that allow the operator to actuate the roller blind, radiator. In the rear of the cab houses the lever that activates if necessary the drum of the working winch.

Technical features

Unlike its predecessors, TT-4M received some increased loading of nodes and frames. For example, the load is projected onto the shield, pressed on the drivetrain and other fittings due to the presence of a sufficiently powerful rear legs. To consolidate specialized equipment crankcases gear located on the frame, equipped with special assistive devices. If you need to attach to the tractor can Rooter, rear linkage, pusher, dozer, drill rig, Ripper.

The Transmission of the tractor was designed in such a way that provided him with four speeds reverse and eight speeds forward.

A Few words about the cost of cars and spare parts

Spare Parts TT-4M certainly can not be called cheap. This is largely due to the fact that the car has a very impressive dimensions and power. It is worth saying that one is the replacement motor could do in the 400–600 thousand Russian rubles. The tractor, released in 2000, will cost about 07 – 1.1 million rubles.
