Forming ditches with a bucket is time consuming and laborious, as the bucket can only hold a certain amount of soil, which must be lifted up with an excavator, turned to the side and emptied next to the ditch into, for example, pellets.

The object of the present invention is to provide a new type of device for forming forest ditches, with which the formation of ditches is much faster and easier. The device according to the invention is characterized in that, depending on the pivot position of the bucket, the ditch can be formed either by digging with a bucket or by plowing with a plow. The device according to the invention is used on moist, poorly water-permeable soil types. The ditch is made in the direction of travel of the excavator. Seedlings can be planted in the resulting seedlings for silviculture. If necessary 2 6 0 7 4 8 larger ditches, deepen the plow furrow with a bucket. Excavated soils are formed as rots for planting. Water is diverted from the middle terrain to the actual ditch. With dry soils, soaking is carried out intermittently, thus avoiding excessive tillage.

The work of the machine is made efficient when the bucket is filled in the early stages of the work movement before using the plow, and the digging soil is made rotten with the boom of the machine straight.

With the drying-sensitive soils, patches are made on the plow from which only the surface, ie the first municipality, is removed.

Thanks to the versatility of the device, the most suitable tillage method can be used for each type of soil, thus achieving the best possible result in silviculture.

A preferred embodiment of the invention is characterized in that the bottom of the bucket is detachable from the bucket. The front edge of the bucket can be used as a detachable member of the ground, and the following plow spreads the loosely detached ground into pellets on both sides of the ditch. '

The invention will now be described by way of example with reference to the accompanying drawing, in which

Figure 1 shows a side view of a device according to the invention.

Figure 2 shows the bucket and plow of the device seen obliquely from above.

Figure 3 shows a bucket according to another embodiment.

The device comprises an excavator 1, in the end of which a pivoting bucket 3 is mounted. With moist, poorly permeable soil types, the ditch is made in the direction of the excavator using a plow, in which case seedlings can be placed in the resulting ridges for silviculture.

The bucket with a removable bottom in Figure 3 is used as a ground release member and the following plow spreads the detached soil into chamfers on both sides of the ditch.

Thanks to the versatility of the equipment, the most suitable tillage method can be used for each type of soil, thus achieving the best possible result in silviculture.

It will be apparent to those skilled in the art that various embodiments of the invention may vary within the scope of the appended claims. 1 t
