Do-it-yourself excavator from a walk-behind tractor

Preparatory stage: where to get the drawing

You need to choose a specific, clear and understandable scheme for assembling your earth-moving machine. There shouldn’t be any difficulties with the choice. Can be used:

  • Scaled-down factory diagrams of large excavators of the “Belarus” type.
  • Ready-made drawings from the Internet, posted by craftsmen. Interesting working options can be found not only in runet, but also on foreign resources.

Having selected the optimal drawing, you need to make an estimate and roughly decide on the costs of consumables and parts.

Hydraulic system

In factory excavators, the hydraulic system consists of 4 parts:

  • slewing bearing part;
  • arrow;
  • ladle;
  • control system.

When making a do-it-yourself earth-moving machine, you can resort to a simplified version. In this case, you will need a slewing ring and boom. The column is mounted on a supporting structure, the role of which can be played by a single-axle tractor. To make the nodes yourself, you need to have 4 hydraulic cylinders to move the boom up and down, control the bucket, and turn. Old hydraulic cylinders from Soviet-made trucks will do.

For the hydraulic drive, it is convenient to use an inexpensive gear pump. It is an easy-to-use, easy-to-repair, low-cost solution. Most often, craftsmen choose NSh-10, combining it with the R-16A distributor.

If necessary, an increase in the power of equipment is achieved by the simultaneous installation of 2 pumps with 2 distribution units.

Mini excavator units

The boom and hydraulic system can be purchased as a set, and simply install them on the base. Such a solution will save you from many mistakes and searching for spare parts. For the entire period of operation, you can forget about setting up the earthmoving machine. But such kits are expensive, and with due experience, home craftsmen prefer to make all the nodes with their own hands. Upgraded units from old technology can also be used.

Constructive decisions

A homemade hand excavator is assembled in the same way as factory car models. In this technique, there are nodes:

  • Carrying frame mounted on tracks from a tractor or motor vehicle.
  • ICE for hydraulics actuation.
  • Slewing bearing.
  • Hydraulics.
  • Ladle.
  • Arrow.

The best solution would be to install equipment on the T40 or create a similar trailer with your own hands for installing a motor, tank, wheelset on it. The stability of the machine will be provided by additional shoe fastening: a pair of “shoes” will keep it from overturning.

The motor can be an internal combustion engine with a capacity of 15 kW. Japanese or even an inexpensive Chinese model.

How to make a bucket

The bucket serves as the working part of the machine. This part is subjected to maximum loads, therefore, increased requirements for the quality of the material are put forward. The optimal solution. sheet steel 6-9 mm thick.

Individual blanks are calculated according to the drawings and cut from the steel sheet, reliably welded together. Steel plates are additionally used to strengthen the sides and bottom. Bucket efficiency and productivity will be improved by weld on strong tines on the front. For them, “fingers” of tracked vehicles can be used.

Usually, when creating homemade earthmoving equipment, a front and back shovel are used. But if necessary, dragline can also be assembled. a technique designed for large pits, trenches, etc. It will be needed when the bucket is working below the platform on which a homemade excavator is installed.

Model selection

A properly assembled mini-excavator is in no way inferior to models created according to all the rules in the factory. It has some advantages for private use: minimal fuel consumption, easy transportation, adaptation to specific needs, low weight. You can work in any area, including warehouses and other enclosed spaces. Usually, such a technique is required at dachas, at country houses, used in digging holes and pits, for shallow communications, etc.

Types of homemade models:

  • An excavator from a walk-behind tractor, based on an existing mini-tractor or just a car. It uses attachments. An autonomous vehicle is being assembled on a caterpillar or automobile wheeled chassis, capable of moving around the site on its own. Another option is a vehicle that can be moved using assistive devices. If necessary, all attachments can be easily dismantled, and the used base is again used for its intended purpose.
  • Mini excavator from scratch. A time consuming option for the most experienced craftsmen. It is impossible for a beginner to cope with such a task, time and money will be wasted. You will need specific skills or qualified assistants, a good baggage of technical knowledge.
  • A simple budget solution. a trailed excavator on a T40 trailer with a frame and a wheel axle.

An autonomous engine, hydraulics and specific equipment are installed.

DIY mini excavator

Frequent renting of earthmoving equipment is a costly procedure and does not provide convenience to the owner of the site. Another thing is your own compact car, with which you can save on the rental service, consume a minimum of fuel and at the same time get all the functions of full-fledged models. It is not easy to create such a technique, but for a true master it is not impossible. How to make a mini excavator with your own hands? First you need to determine its parameters and type.


The stand was made from a 50 × 50 profile pipe with a thickness of 4 mm, which was welded to stiffening ribs. For the manufacture of loader arrows, a 60x40x4 mm pipe was used. A hydraulic system is installed to set the entire structure in motion. lifting hydraulic cylinders 50x25x250 mm, evacuation cylinders 42x20x250 mm. Additionally, a removable bucket is installed on the frame, forks (photo) (welded from a profile pipe 60x40x 4 mm), a dozer blade.

Formerly a back walk in America, Gravely was the largest American manufacturer of walk-behind tractors, and several more American companies have made them since the early 1900s. But the larger tractors produced after World War II drained the market for many tractors, and even Gravely stopped production around 2003.

American manufacturers have never introduced much innovation to this equipment sector either. even in the last days of their production, Gravely still lacked double-sided rudders. While Europeans adopted this extremely practical design in the 1960s, almost all tillers are now produced in Europe, mainly in Italy, which has more than 15 brands. Two Italian brands found in North America. these are BCS America (based in Portland, Oregon) and Grillo, with BCS being the most famous as they have been imported since the mid 1970s.
