Having a powerful brush cutter, you can convert it into a cultivator for weeding between the rows. There are special attachments for sale for this, but if you wish, you can make them yourself. Such equipment is installed on a brush cutter instead of a knife, and the device itself does not need to be remodeled. The scythe can still be used for its main purpose.
Materials:
- sheet steel at least 3mm thick;
- bolts M6 or M8 with nuts and washers 60 mm – 32 pcs.
Making nozzles
First you need to decide on the diameter of the base of the nozzle.
It will be made in the form of a disk that needs to be cut from sheet steel. It is optimal that the attachment matches the size of a standard mowing blade. If the motor of the brush cutter is powerful, then it can be slightly increased to suit the size of the row spacing.
The center of the nozzle is approximately marked on a sheet of steel, and a 6 or 8 mm hole is drilled.
A bolt is inserted into it and tightened with a nut. From a thread folded in half, you need to knit a loop with a length equal to the radius of the disk. By throwing one edge of the loop over the bolt and catching it with a marker, you need to draw a circle for the nozzle.
The circle is cut using an available tool.After this, the edge of the disk should be sanded to remove burrs.
Now you need to drill the central hole in the disk to fit the mounting diameter of the washer used to install the mowing blades. This can be done with a step drill.
The prepared disk should be divided into 8 sectors. Each of them is divided into 4 more segments.
Using the resulting markings, 24 holes are drilled for the existing bolts.
If desired, you can make another hole in the center of each segment to fill in the gaps. It is very important to maintain symmetry to maintain the balance of the disk.
The surface of the disk is ground to remove burrs obtained during drilling. A bolt with a washer is inserted into each hole and tightened with a nut.
The resulting attachment is clamped into the lawn mower like a regular knife. Rotating, its bolted spikes capture the top layer of soil, uprooting weeds and damaging their root system. In this case, the stems are ground, so they will not be able to recover even if it rains.
The attachment works really well, especially on soft sandy soils.
Unfortunately, it raises a lot of dust, so it is better to cultivate out of the wind. When working, you should wear high boots and glasses, as pebbles in the soil may fly out. If the ground is soft and without cobblestones, and the nozzle is well centered, then the scythe gearbox will not break.
This is much faster than manually swinging a hoe for hours on end.
The responsibility is always yours
This is not a guide to action, but just an introduction. If you decide to make something extra, do it at your own peril and risk.
