Instructions for using the mechanism for attaching agricultural implements
The hitch mechanism is used to attach mounted and semi-mounted agricultural implements to the MTZ-82/80 tractor.
The mechanism structure is shown in Fig. 72.
The forks of the braces are connected by bolts to longitudinal rods 10. The forks have slots. When operating the tractor with wide-cut implements, install the fork on the slot. This will ensure better adaptability of the implement’s organs to the soil topography along the working width.
The design of the right brace 8 provides for its length adjustment using handle 7.
To decrease the length of the brace, the handle should be rotated counterclockwise, to increase it - clockwise.
Do not adjust the left brace when working with mounted implements; its length must be constant and equal to 515 mm. To level the plow in the transverse plane, adjust the right brace.
Leveling the depth of travel of the front and rear working parts of the mounted implement is ensured by adjusting the length of the central link. Adjustment is carried out by rotating the pipe using a handle.
Make sure that the lock nuts of the brace, limit chains and central link are securely tightened: loosening the lock nuts can lead to disruption of the adjustment of the linkage mechanism and to thread breakage.
When moving a tractor with an implement over long distances, the central link must be shortened to improve the cross-country ability of the unit.
Restrictive chains are used to limit the lateral movements of implements. The chains are attached at one end to the longitudinal rods, and at the other to brackets installed on the axis of the longitudinal rods. Adjusting bolts are screwed into the brackets, which, resting against the housing of the rear axle of the tractor, provide tension on the chains when lifting the implements into the transport position to reduce their swinging in the transverse plane.
Bolt adjustment
Adjust bolts 12 (Fig. 72) in the following order:
1. Attach the implement to the hinges of the longitudinal and central links. Screw the adjusting bolts into the brackets until they are tight.
2. Raise the implement so that its working parts do not touch the ground.
3. Adjust the length of the limit chains by rotating the ties so as to ensure freedom of rolling of the trailing link joints in accordance with the implement’s operating manual. For mounted plows, the freedom of rolling in the horizontal plane should be 120 mm in each direction from the average position.
4. Adjust the length of the right brace to the specified working depth (when working with plows).
5. Raise the implement to the transport position, unscrewing the bolts from the brackets, tighten the chains so that they sag slightly, ensuring that the implement swings no more than 20 mm in both directions.
6. Securely secure the bolts with locknuts. Each change in the length of the right brace must be accompanied by an adjustment of the right bracket bolt to ensure self-locking of the limit chains.
When inter-row cultivation, sowing, and also when working with a towed device, the longitudinal rods of the hitch mechanism must be completely blocked from lateral movements in order to avoid damage to plants or rocking of the trailer. Blocking is carried out by shortening the length of the chains as much as possible within the limits of the existing adjustment; in this case, the adjusting bolts must be screwed into the bracket all the way.
Violation of this order may lead to breakage of limiting circuits or other damage.

Rear linkage device
The structure is attached to the rear wall of the tractor rear axle housing. The upper rotary shaft of the hitch is placed with its axis in the cylindrical supports of the bracket, which is bolted to the upper edge of the rear wall of the axle housing. The central part of the shaft interacts through a splined connection through a lever 7 with a power hydraulic cylinder 6 , which provides lifting and lowering. On the left and right sides of the shaft there are lifting levers 5 connected to the corresponding left and right, vertically placed, length-adjustable braces 3 and 9 . The braces are connected to the lower longitudinal strips 4 and 10 .
The connection is made pivotally with fingers through forks 2 . With their front ends, the longitudinal left and right lower bars are attached to the edges of the axle installed in the lower part of the rear axle housing. The rear ends are equipped with spherical hinges 1 for convenient connection with the towbars of attached machines. Additionally, the lower bars are equipped with length-adjustable ties 12 . To ensure the connection of attachments and machines, the design includes a central upper rod 8 with connecting ball joints at the ends. Its front part is connected to the positioner bracket, the rear part is attached to the mounted device. In the standard configuration, a transverse bar 13 with a towing eyelet with a locking pin is hingedly attached to the rear ends of the lower bars for attaching towbars of machines and vehicles.
Considering the location of the attachment points of the lower longitudinal bars to the axle body, the MTZ rear linkage has a three-point design, which provides a fairly rigid attachment to the tractor without lateral movement of the attachment. This connection requires the obligatory deepening of the working tillage implements of the mounted machine when the unit turns.
Necessary equipment for the MTZ 82 tractor
Heated mirrors: benefits, design and installation yourself
The fastening of a specific element is carried out on the frame or chassis by a technician in combination with a control system. But there are models that are designed to work with their own chassis. If it is possible to install mechanisms for the rear and front use of mounted devices, then it is possible to expand the capabilities of innovative tractor models, regardless of their company and manufacturer. What MTZ model range exists is indicated in this article.
Characteristics of the MTZ 82 tractor.

After the work has been done, all that remains is to place the seeds in the grooves and sprinkle with soil. The soil can be prepared using a disc or petal hiller.
Seeders
The presented devices for the MTZ 82 tractor allow you to sow planting material in the form of seeds efficiently and quickly. They arrive through bunkers at a specific distance from each other. Thanks to this, it is possible to achieve harmony in the rows of crops planted nearby. You can learn how to use Buhler for its intended purpose in this article.
Seeders are designed for sowing agricultural crops.
Lugs
When working with a tractor, it becomes necessary to create an adhesion to the surface. For these purposes, lugs are used. They increase the traction force of the tractor during plowing, hilling and collecting root crops. Today you can purchase these products in any size or type.
Types of attachments
According to the location of devices for installing attachments, tractor attachments are divided into:
- Installed at the rear of the tractor are rear universal attachments, with the use of which sowing and cultivating complexes, mowers, reapers, moldboard and excavator equipment, brush mechanisms, etc. are aggregated;
- The front mechanisms have the same design as the rear linkage, with the use of which headers, front mowers and loaders, sprayers, front dumps, snow removal systems, etc. are installed;
- A side hitch used to connect to the tractor mechanisms located on the sides of the base chassis during operation. Lateral aggregation is carried out using special mechanisms included in the delivery package of the aggregated devices. Single-beam mowers and brush cutters are aggregated in this way;
- Individual attachments used to install equipment that cannot be mounted using universal attachments. To secure these types of mechanisms, the tractor sub-engine frame is used.

The simplest and most common type of special attachment, of course, can be called KUN on the MTZ-82. KUN is a universal mounted hay hauler, which is essentially a tractor front-end hydraulic loader for moving, lifting and lowering various large loads. KUN on the MTZ-82 tractor is used not only for moving and storing hay, but also for transporting bulk and bulk cargo. They are modernized and manufactured independently; a prominent representative of the tuned KUN is the bucket.
Photo of MTZ 82 with KUN
Most often, the PKU-0.8 device is mounted on the MTZ-82 as a KUN; the main technical characteristics are as follows:
- weight of lifted loads up to 800 kilograms;
- high-rise ceiling up to 3.5 meters;
- weight of the mounted loader up to 700 kg;
- maximum travel speed with load up to 20 km/h.
Adjustments
The position of the mounted machine is adjusted by changing the length of the braces 3.9 and the upper central link 8 . The braces adjust the transverse arrangement of the attachments. Standardly, the left brace is not adjusted; adjustment is made by changing the length of the right brace, equipped with a handle 15 for convenient rotation of the screw. The position of the machine in the longitudinal position relative to the horizon is adjusted by changing the length of the upper central link.
The tension of the couplers connected to the longitudinal lower links and the tractor body adjusts the lateral movement of the attachment relative to the axis of movement of the tractor. Loose ties allow for slight movement. To ensure a rigid position of the machine, for example, for inter-row cultivation of crops or during sowing with a mounted seeder, the couplers are tensioned as much as possible, eliminating lateral rocking.
For convenient adjustment of length and tension, threaded pairs of screws and ties have left and right threads. The tie rods are secured with control nuts.
An increase in load capacity is achieved by installing additional pins at the connection of the brace forks and longitudinal bars in additional holes located closer to the rear mounting hinges. In this case, the forks must be turned with the grooves forward so that the forks do not affect the pins connecting the ends of the lower longitudinal rods. To ensure reliable fastening of connections in the hinge joints, it is necessary to use standard locking pins and cotter pin nuts for the tension bolts of the structure.
The nature of the malfunction of the MTZ 80 tractor gearbox
Malfunctions and breakdowns in the gearbox occur both as a result of natural wear and tear of the elements present here, and in the absence of proper care of this system by the driver. In particular, it is not recommended to pull the lever when moving it from one mode to another.
Signs of when MTZ 80 gearbox repair is necessary:
- large free play of the lever;
- difficulty changing gears;
- extraneous noise from the gearbox.
The MTZ 82 transfer case is subject to periodic maintenance. This procedure includes changing the lubricant. This is necessary to prevent premature wear of the rollers and the driven race of the freewheel.
In some cases, the cause of knocking noises may lie in the fact that there is a breakdown of the gear teeth. Periodically, the tractor owner must tighten the threaded connections.
Gearbox repair begins with dismantling the MTZ 82/80 gearbox. This procedure is relevant if there are worn bearings. These consumables must be replaced. If squeaks occur, it is necessary to check the condition of the gear shafts. As a rule, they require adjustment.
It is necessary to check the shift fork if play in the switch begins to appear, thanks to which the optimal mode is set. When the shift forks break (wear out), the linkage falls out and a violation of the rod adjustment occurs. In this case, you should check the condition of the gear teeth and clamps. The forks can be changed either as an assembly or separately. It is necessary to check the gaps of the shift pin and gearbox fork on the MTZ 80 if involuntary activation of speed modes is observed. The optimal gap is 2.2 millimeters.
You also need to pay attention to the clutch. If it is incorrectly adjusted on a vehicle, this is often a consequence of the fact that the gearbox is not operating correctly
During a major overhaul of the transmission system, the gearbox is removed and is subject to a complete overhaul. This procedure is necessary to replace the worn components present here. It is better to entrust major repairs to craftsmen who work in auto repair shops that have lifting equipment and diagnostic stands. Assembly is carried out in reverse order.
Thus, the gearbox (MTG) present on a wheeled tractor is a reliable unit. It is necessary to periodically undergo maintenance, cleaning and lubrication in order to minimize the risk of serious breakdowns.
Automatic hitch SA 1 (Triangle)
A device for automatically attaching machines on MTZ 80(82) “Automatic coupler SA 1” (the so-called “triangle”), is attached by three points to the hitch - two hinges of the ends of the lower longitudinal bars and the central link. The contact connecting part of CA 1 is made of a metal profile in the shape of a triangle. Fixation is carried out with a spring lock with a latch. When hanging, the triangle fits its profile into the internal profile of the triangle of the machine being hung. With the upper guide angle 8, the device, when connected, aligns the hole of the outer triangle with the spring-loaded latch 4 of the triangle on the tractor. If a match is made, the latch closes automatically under the action of a spring. To disconnect the mounted device, press down the lock lever 9 and disengage the triangle 3 by lowering the linkage. The drive of the control lever for the coupling device lock is brought out using a cable 10 to the driver's seat to ensure operation without outside help.
The CA 1 device is universal and is used in mounted systems of tractors of different brands.
The MTZ 82(80) hitch has a similar design to all wheeled tractors of the MTZ family and universal row-crop machines of the YuMZ-6, T-40, T-25 brands. Additionally, the hitch of modern tractors can be equipped with a lift-type towing device, as well as towing devices of various designs. Crawler tractors are equipped with a reinforced hitch with the possibility of two or three point connection of the hitch to the tractor.
