Excavator units on a mini-tractor: the subtleties of selection and operation

Mini tractors have a fairly wide functionality. But these devices can only realize it when supplemented with various auxiliary accessories. An important role in this is played by the excavator installation on a mini-tractor.

Wheeled excavator tractors were produced several decades ago. Of course, those machines have long been replaced by more modern and adequate versions. However, they are all quite expensive. Moreover, a rigidly fixed excavator-type nozzle is not always needed. Sometimes it interferes with the alteration of the device for other applications.

The mounted excavator unit allows:

• dig a pit;
• prepare a trench;
• to plan the territory and change its relief;
• dig holes for poles, planting plants;
• form embankments;
• prepare dams;
• destroy buildings made of bricks, reinforced concrete and other durable materials.

When digging pits, the excavated soil can be dumped into a dump or loaded into the body of a dump truck. As for the laying of trenches, their smallest width is 30 cm. Smaller trenches are recommended to be done manually. The mini-tractor excavators produced today can be supplemented with buckets of various geometries. Their volume also differs greatly.

This technique will make it possible to prepare hundreds of neat holes for planting trees without much difficulty during a working day. A bucket attached to a loader can be effective in filling depressions and ditches. He is also good at tearing soil from hills. Moreover, high-quality forklifts can help with the construction of roads under high stress.

Excavator-type attachments can have the following parameters:

• engine power - from 23 to 50 liters. with.;
• dry weight - from 400 to 500 kg;
• rotation of the mechanism - from 160 to 180 degrees;
• digging radius - from 2.8 to 3.2 m;
• bucket lifting height - up to 1.85 m;
• bucket lifting capacity - up to 200-250 kg.

The detached towbar supports ensure excellent machine stability on all types of ground. Some versions can be executed with a shifting axis. They are distinguished by an increased radius of the arrow maneuver.

High quality backhoe loaders:

• are distinguished by increased productivity;
• more compact than combined units, but have the same power;
• relatively light (no more than 450 kg);
• easy to manage;
• quickly transferred to the transport position and back;
• allow you to save money, giving you the opportunity to refuse to purchase several mechanisms at once.

Attachments manufactured by leading manufacturers have an increased margin of safety. The operating time is at least 5 years. Such mechanisms can be installed on all mini tractors. They are also compatible with full-fledged tractors of the MTZ, Zubr, and Belarus brands.

Among the Belarusian units, the BL-21 and TTD-036 models attract attention. They are produced, respectively, by the firms "Blooming" and "Technotransdetal". Both versions are designed to be mounted on the rear linkage of tractors.

• Model TTD-036 recommended for interaction with "Belarus 320". The bucket has a capacity of 0.36 m3, and its width is 30 cm.According to the manufacturer, such a mounted excavator can lift soil from a depth of up to 1.8 m.

• BL-21 characteristics turn out to be much more modest. Its bucket rakes no more than 0.1 cubic meters. m of soil, but the depth was increased to 2.2 m.At the same time, the processing radius is approximately 3 m.

4 types of miniature trailed excavators of the Avant brand deserve attention of consumers. In addition to the typical bucket, the basic delivery option contains support blades. Each model is equipped with rear support legs. Control is carried out by means of levers and buttons accessible from the driver's seat, and a remote option is also provided.

The maximum precision of the work is ensured by the full-turn handle. The excavators supplied by Avant have a mass of up to 370 kg. In this case, the excavation can be carried out from a depth of up to 2.5 m.

Installations from the Landformer concern also have a good reputation. They are made in Germany, however, Chinese or Japanese motors are installed. By default, there are 3 types of hydraulic supports and buckets.

The power of Landformer installations reaches 9 liters. with. Devices of this brand lift the soil from a depth of 2.2 m. They can load it into car bodies and dumps up to 2.4 m high. The force applied by the working body reaches 800 kg.

As you can see, choosing the option that suits you is not difficult. The main factors when choosing a specific version are:

• clarity of positioning of buckets;
• the stability of the mini-excavator itself;
• the size of the cylinders;
• strength and mechanical stability of the bucket being installed.
