In most countries of Europe and North America, wood chips obtained in the process of cutting brushwood and branches are widely used in intensive gardens and parks as a mulching agent. Technologies that involve the disposal of branches have a wide list of technological operations. One of the most common involves manual pruning with the help of simple technical tools such as a chainsaw and cordless saws. The cut wood is transported and piled into piles, which are burned when there is enough accumulation. This technology is primarily environmentally harmful, as it pollutes the environment. Therefore, the property of using chopped branches as mulch between rows in gardens and park alleys is quite an important factor.

The goal is to study the application of the technology of cutting branches into chips with a high-tech unit, which will make it possible to reduce labor costs by approximately 1.5 times, fuel costs by 1.4 times, eliminate environmental pollution, replenish the soil with organic and mineral additives and use additional areas of land. which are now set aside for wood burning sites.

Technologies that involve the disposal of branches after trimming the crown of trees have the most diverse directions of use of the pruning product and a wide list of technological operations. Each of them is interesting in its own way, has advantages and disadvantages, and therefore requires more detailed coverage.

One of the oldest and most primitive technologies involves manually loading cut wood onto vehicles, taking the branches to storage sites, where they are burned. This technology is poorly mechanized and requires extensive use of unproductive manual labor. The coefficient of utilization of the carrying capacity of vehicles is very low, as it is impossible to place the collected wood tightly under load. Currently, it is used in small farms.
