The aim of the work is to find technical solutions that provide a complete reversal of the transmission on the example of an integral tractor, while allowing maximum use of commercially available units or installed as an option for a serial machine. The objects of study are mainly the chassis of a wheeled integral tractor designed for agriculture. The relevance of creating fully reversible transmissions for integral tractors and other agricultural, road-building and transport machines is shown. The variants of installation places for the reverse gear are considered, the features of loading and the principles of designing the reverse gear for specific placement points are analyzed. The most promising options for the case of an integral tractor based on a serially produced chassis were chosen - placement of a controlled power distribution mechanism in the rear axle gear housing or instead of wheel gears. Kinematic schemes and a technique for determining gear ratios and kinematic parameters are proposed. The reverse gear control technologies and the technological base for the design and manufacture of such mechanisms are indicated: when designing an integral tractor in accordance with the principle of maximum unification with a serial chassis, it is advisable to place the reverse gear in the drive axle housing; when developing an original reverse transmission and a new carrier system, the reverse gear should be located in front of the gearbox; in the design of the reverse gear, it is preferable not to use a blocking clutch, replacing it with a planetary gear set and a brake.
