Features and stages of self-production of a garden shredder


To make a garden shredder with your own hands, it is very important not only to understand its operating principle, but also to know how it is arranged. Otherwise, it will be practically impossible to make the correct drawings and assemble a home-made convenient machine for grinding in a single design.

Types of garden shredders and their purpose

The standard design of all garden shredders is similar in most cases, and represented by the following components:

  • motor;
  • working shaft with knives;
  • metal frame;
  • receiving box;
  • protective cover.

The design of the grinder is mounted on a standard two-wheeled base, which makes it convenient and easy to move. The device allows you to quickly dispose of various garden waste in the form of plant stems, wood waste, fallen leaves, as well as branches and grass or apples and other fruits that have fallen from trees. As a result of processing wood or vegetable debris, you can get a useful and very effective fertilizer for feeding plants, the value of which is not lower than some types of manure.

A fairly rich assortment of such equipment is currently on sale, but the models on the market differ in technical parameters. For the correct choice of the unit you need to determine the goals and conditions of use:

  • knife modelscharacterized by mounting the engine on the shaft of a metal disk. The design has a pair or more knives, and the speed and quality of the grinding performed depends on the power indicators of the engine and the material of the knives. The advantage of such grinding methods is the high-quality processing of soft or freshly cut wood. Also, such a wood crusher helps get rid of small bushes and dried stem parts of annual plants. It should be remembered that the knife cutting machine grinds fresh branches with a diameter of not more than 4 cm and dry branches up to 2.5 cm thick.
  • milling models they are similar to a knife wind chopper, but a powerful steel milling cutter, represented by a coarse gear, is mounted on the motor shaft. The rotation is carried out at low speed, which makes it easy to grind even fairly thick and dry branches, as well as tree bark. Such a crusher is impractical to use for grinding fresh or thin branches;
  • universal cutting able to work equally effectively with any kind of crushed material. This technique is equipped with a universal mill-turbine. The principle of operation is phased grinding mechanisms.

The next classification option for garden shredders are differences in type of material, used to make the case:

  • metal option;
  • plastic option.

Power indicators and performance level, allows subdivide garden shredders into the following types of models:

  • household type;
  • professional type;
  • semi-professional type.

When choosing, you should focus not only on the size of the branches, but also the age-related features of garden plantings. The amateur version of units is suitable for processing the thinnest branches and young plants. To chop thick branches, professional models are used.

How to choose a garden shredder

Do-it-yourself garden shredders of branches, stems and herbs with your own hands: drawings, device, installation steps

The most commonly made disk version based on saws. It is necessary to purchase one and a half dozen paintings of solid steel with nozzles for teeth. Self-made technology:

  • pick up or make a set of washers-gaskets made of steel for the distribution of discs on the shaft. The standard gap between the saws should not be more and not less than a centimeter.
  • to put disks with washers on the turned shaft, having teeth with displacement or randomly, which will extend the life of the structure;
  • weld a reliable frame from the corners and channels, after which, in the lower part, install the foundation base for installing the electric motor;
  • to arrange pedestals on the transverse structures for installing ball bearings with a fixed working shaft;
  • equip a working robust grinding hopper with reliable walls and a support plate or a passive knife;
  • organize a bell for the supply of branches necessary to direct the material to the chopper and protect the hands from injury.

In the process of pruning garden plantings, it is not recommended to mix branches and other wood debris. With separate chopping, quite decent firewood is obtained, and processing into wood chips for a home smokehouse is carried out. It is allowed to make a grinder based on a chainsaw, but creating such a design option is quite time-consuming.

How to make a homemade apple chopper

In addition to wood chips, an effective and sufficiently productive apple shredder is very popular in home gardening. Such an aggregate is not too difficult to perform, guided by the following recommendations:

  • from sheet metal d 80 mm on a lathe, perform exit steps for the shaft and under the bearings;
  • on a milling machine, a gear shaft is made with triangular notches along the entire length of the teeth;
  • for the manufacture of the case, the outer steel part of the old top-loading washing machine, welded into a solid box, can be used;
  • the execution in the box of a small gap, which falls on the distance between the working shaft and the wall of the housing;
  • for smooth rotation of the shaft and its reliable fastening, standard circular bearing units are used;
  • welding from the corners of the support frame and the implementation of a wooden base for installing the tank under the reception of the mass leaving the grinder;
  • the use of special ballast equipment to equip the control unit, which will enable turning the equipment on and off;
  • belt fixing by means of a special bolt and screwing onto the frame of the handle and rollers, simplifying the operation of the unit.

At the final stage, the case is fixed to the upper corners of the frame using bolts. The electric motor is located in the side of the structure.

How to make a grass chopper yourself

Making a garden shredder for a do-it-yourself walk-behind tractor

Effective chopper branches for walk-behind tractor can significantly reduce the amount of plant debris in the garden. Factory-made grinders are perfect for any type of walk-behind tractor and motor cultivator with belt drive from the engine pulley to the gear pulley.

For self-manufacturing, you will need to use the materials and tools presented:

  • walk-behind tractor;
  • knives from an electric planer;
  • pulley and shaft;
  • bearings;
  • channel;
  • sheet metal 3 mm thick;
  • bolts, nuts and washers;
  • welding machine;
  • grinder;
  • a hammer;
  • a set of keys;
  • pliers
  • a drill.

Self-made technology:

  • we weld the base from the channel and install a fixed knife;
  • we carry out a drive shaft with knives from an electric plane;
  • we install a pulley on a shaft with a cutting apparatus, which will allow it to be driven by a belt drive from a walk-behind tractor;
  • we weld and install a receiving hopper for grinding vegetable debris.

At the final stage, we install the grinding unit on the front of the walk-behind tractor and pull the belt drive onto the pulley.

How to use chopped biomass as fertilizer

As biomass for fertilizers, crushed cardboard mass, kitchen waste and vegetable waste are used. This is a great alternative to purchased fertilizers. Very important to properly prepare biomass for use in household and garden plots as highly effective top dressings. For this purpose, special composters or standard compost heaps are used.

At the very bottom of the compost heap is laid mass represented by shredded thick shoots of perennial plants. On top of this layer is covered with a small amount of already mature compost or fertile soil. Then shredded vegetable waste is poured in layers. It is necessary to pour each layer with a two-centimeter layer of garden soil with dolomite or chalk at the rate of a couple of kilograms for each cubic meter of composted mass.

As a result of the natural processes occurring inside the composted mass, valuable fertilizer is formed, which can be used in practically unlimited quantities to improve the qualitative characteristics of the soil in the home garden or to feed the cultivated garden plants. Compost is allowed to be introduced into the soil throughout the entire growing season, but the optimal effect can be obtained when applied in the spring and in the autumn period.

Around perennials and garden plants, as well as flower beds and flower beds, compost biomass is poured in a layer of 20-50 mm and mixed slightly with the soil. To improve the condition of lawn grass, it is enough to pour a centimeter layer.

How to make a garden chopper do it yourself

Self-made shredders for grass, falling fruits and any other plant debris are today very reliable assistants to gardeners and gardeners. With the help of such equipment it is possible not only easily and quickly to clear garbage from the household territory, but also to obtain high-quality and very effective, environmentally friendly fertilizer.
