Belarus 80.1/80.2/82.1/82.2/82Р —Operation and Service Manual Section 2.General Description and Technical Characteristics 5 2. GENERAL DESCRIPTION AND TECHNICAL CHARACTERISTICS OF TRACTORS Tractors Belarus are designed to perform a variety of farm jobs, in combination with different mounted, semi-mounted and trailer-type machinery and implements. Besides, tractors can be assigned to ful- fill heavy-duty works when ganged up with earthmoving, shovel dredging, load- ing, post-hole digging implements; also, they can be used on transport missions and for driving various stationary farm outfits. Tractor Belarus 82Р is designed for an all- round mechanization of growing rice and rotation of companion crops. All the technical facilities to be used in combination with Belarus tractors should be agreed with the Production Associa- tion «Minsk Tractor Works» (PA MTW). 2.1. TRACTOR DESIGN AND CON- STRUCTION IN BRIEF Wheeled tractors Belarus 80.1 (see Fig. 1), Belarus 80.2, Belarus 82.1 (рис. 2), and Belarus 82.2 are multi- purpose agricultural machines, Class 1,4 tf (14 kN). These tractors differ from one another by the type of running gear: Bel- arus 80.1/80.2 – with one driving axle, Belarus 82.1/82.2 – with two driving axles. The tractors are of a semi-frame construction. Their skeleton consists of a semi-frame, housings of the clutch, change-speed gearbox and rear axle. The diesel-engine forepart is fastened on the front beam, while its aft-part is rigidly connected to the transmission clutch housing. Index .2 means a modernized version of the respective model, wherein one or several updated assemblies or units are installed, for example: • the front driving axle with planet-and- spur reducing gearboxes (on tractors Belarus–82.2); • bonnet, cab roof, cab mudguards of a modified design (on tractors Belarus 80.2/82.2). Tractor Power Train incorporates a clutch, superreducer and speed gearbox, rear axle with automatic differential lock-up, and rear P.T.O. shaft with two-speed independent and synchronized drives. Tractors with two driving axles are equipped with a front driving axle (FDA) and drives — a transfer box, intermediate and front universaljoint shafts, and an intermediate bearing. The Tractor Steering Control can be of hydromechanical type (with a HSB body) or hydrostatic steering control type, with a metering pump (HSCU). The hydromechanical control outfit consists of a worm, quadrant and the hydraulic steering booster (HSB). The hydrostatic steering control unit (HSCU) incorporates a gerotor-type metering pump which is installed in the steering column on the front cab wall, diesel-engine driven feed gear- pump, a hydraulic cylinder located in the steering trapezoid of the front driving axle (tractors Belarus 82.1/82.2) or tractor fore (non driving) axle (Belarus 80.1/80.2). The HSCU is fed with oil from the hydraulic hitch linkage system tank. Tractors with installed HSCU unit feature a hydraulic drive of the rear-axle differential lock-up unit, whose control cock is located under the slanted footboard of the cab. Locking action is effected by pressing the pedal located to the left of the service brake pedals. The FDA Drive is effected from the speed- change GB to ensure synchronized rotation of the front and rear wheels in any gear se- lected. The front driving axle is pivoted to the fore beam, thus, ensuring its free rolling motions. Provision is made for stepless adjustment of the front (for tractors equipped with a HSB) and rear wheels track. To im- plove tyre traction performance, as well as tractor steerability, additional counterweights can be mounted on the fore-beam totaling to 220 or 510 кг .

General description and technical characteristics 7 The tractor Belarus 82 P, intended for work on rice-growing fields, features increased ground clearance and, also, by a modified propulsion gear – wide cross- section low-pressure tyres, with well- developed (scalloped) lugs and low- profile tread pattern. An increased ground clearance is achieved through installation of an additional hub drive, as well as the use of tyres of larger diame- ters. The rice-field tractor is equipped with a FDA control and parking brake in- terlocking mechanism. The Tractor Hitch Linkage System incorporates a hydraulic system and a rear hitch linkage. The hydraulic system com- prises an oil pump, distributor, draft control, rear and external hydraulic cylinders. Trac- tor may be shipped as equipped with a draft (position) control system or without this system. The Rear Hitch Linkage is a four-link mechanism, with length-adjustable drop links. A RHL fixing mechanism is provided to hold mounted implements at the extreme upper position on transport missions. When running with trailed machines, a cross-bar with a hitch yoke can be used, while on transport missions — install a towing arrangement with a self coupling device and a hydraulic pick-up hook. Трактор оборудован пневматической системой управления тормозами при- цепов с пневматическим или гидрав- лическим приводом тормозов. Electrical Equipment — d.c., 12 V rated voltage. Tractor (Unitized) Cab is a safety sealed frame-and-panel structure, equipped with a single torsion seat, adjustable to operator’s height and weight. An additional seat (option) can be installed. Cab windows are safety heat-absorbing monolithic glass. The cab is furnished with a heating and air- ventilation system, a dome light, windscreen wipers, sun visor, rear-view mirror. Natural ventilation of the cab is achieved through opened sunroof, rear and side windows. Provision is made for the change of angle of the steering wheel column within 15 deg., as a matter of convenience when entering and leaving the cab or operating the tractor, as well as for height adjustment within 100 mm. Also provided is a three-step sideboard and handrails. Installation of a unitized cab is paralleled with installation of a small-size cab on certain tractor batches, against a separate order. The diesel-engine cover is attached to the radiator grille facing frame by hinges; in its open position it is fixed with an arresting catch. On a separate order, the tractor may be supplied with optional extras: a drive pul- ley, side P.T.O., rear P.T.O. shaft replace- able tail-end (21 splines), reverse-reducer  , additional counterweights, P.T.O.-2 tail-end guard, wheels with 18,4L-30; 9,5-42 tyres, starting pre-heater, automatic coupler СА- 1, hydraulic pick-up hook ( ТСУ-2), pneu- matic adapter, a cross-bar of the coupling device ( ТСУ-1-Ж), device ТСУ- З-К (haul- and-draw coupler arrangement), break- away couplings with bracket, coupling hos- es, left-hand adjustable drop link, auxiliary spacer-ring piece for mounting rear wheels, first aid kit, additional seat, and others. Besides, the tractor can be equipped with a travel speed superreducer which is purchased separately by the user, on his own. Also, the tractor should be equipped with a gearbox suitable for installation of the speed superreducer. The left-hand cab door can be locked.
