How To Put The Disc On The Trimmer
Varieties of trimmer discs
The trimmer disc is available in different materials. And in order to decide which trimmer disc is better. metal or plastic, you need to decide what you will mow. So, a plastic disc is designed for short and thin grass, while a metal one can easily cope with very thick and tall grass, shrubs, dry grass.
The shape of the cutter disc for the trimmer can be with 2, 3 or 4 cutting edges. Typically, these accessories are included in the basic set of tools for low and medium power. With it, you can fight dense grass and small shrubs.
On powerful and professional equipment, saw blades are installed, which have up to 80 teeth, and sometimes also carbide (victorious) drinks on the teeth. Such a victorious trimmer disc is rarely used in private households, it is mainly used on professional lawn mowers. It has a very long service life and versatility for both fresh grass and dry impassable Weeds.
The discs also differ in blade thickness, which can be from 1.3 to 4 mm. Thin discs cut grass cleanly, quickly and accurately, but they dull faster. The thickest knives do NOT wear out for quite a long time, but are more suitable for coarse growth and Burian.
As practice shows, the most common shape of a trimmer knife is round with teeth around the circumference. A variety with 4 large teeth and a row of small teeth between them is also becoming a frequent choice. They most effectively help in cleaning the area, can be easily installed on any trimmer model.
Disc trimmer benefits
When you have to mow Tall grass, it often gets tangled on the line and trimmer reel, forcing you to stop work and remove these balls of grass with your hands. In addition, over time, the trimmer coil may break from this. As for the cutting blade. it can handle tall grass with ease.
The disc is also more effective when you need to cut dry grass, burdocks, hogweed, bushes and undergrowth. The only thing a knife is afraid of is stones. For haymaking, the trimmer disc is the ideal solution.
over, metal discs do not wear out, so they do not need to be changed, unlike fishing line, which eventually deteriorates.
Trimmer disc
The trimmer is a fairly common garden tool purchased for cutting grass. Models with line are suitable for soft grass, but if you need to tackle coarse undergrowth and shrubs, the disc trimmer is indispensable.
Fitting the disc to the trimmer and observing safety measures
After you have decided which disc to take for the trimmer, you need to learn how to install it correctly. Initially, make sure that the Landing hole on the disc is the correct hole, otherwise the disc will simply not fit your trimmer. And if you do succeed in securing it to the instrument, the disc may jump off during operation and seriously injure you.
Usually, each manufacturer for each model of the produced equipment also produces the corresponding equipment, so the choice of a knife should not be something very difficult. When you have installed the disc, check how securely it is attached.
If the disc is metal, it can only be installed on a trimmer with a straight boom, as this is due to the design of the unit. When mowing grass, bushes and thin trees, the disc, bumping into an obstacle (for example, a stone), bounces back, that is, in your direction. And when the bar is straight, the distance from the head to the feet is sufficient for your safety.

How to put the disc on the trimmer correctly. How to mow with a trimmer (with a metal knife)
First walk around the site.
A) to find:
– the boundaries of the area where you will mow with a trimmer;
– where are plants in the grass that cannot be cut (flowers, bushes, seedlings)
b) to determine the starting point (you need to start mowing with the trimmer from the lightest area, in order to create an open space so that when moving into larger grass you can better see the mowing area)
c) to determine the direction of cutting with the trimmer (depending on the presence of ditches, slopes and slopes of the grass)
d) to determine how to cut with a trimmer:
– in folds. If the area is flat with flat grass (so there are fewer transitions)
– with the transition back to a clean place, when Mowing lodged grass (its slope should be directed forward)
– Cutting across a large slope (it is much easier to cut across a slope with the trimmer than going up and down a slope).
We put a metal knife: weed or hay. Protection, i.e. Knife guard, compulsory (no additional protection for the trimmer head)
– in order to mow with a trimmer, you must assemble in order: a driver chuck, a metal knife (you need to put it without skewing), a support cup, fastening flange and screw a nut (left thread)
– insert the locking pin and turn the metal knife to lock the output shaft of the Husqvarna gearbox;
– tighten the nut with a wrench with a force of 3. 5 kg / m;
When mowing with a metal blade trimmer, you must set:
– speed of movement of the knife, depending on the irregularities (so that the trimmer mows cleaner and faster)
– working delight of the disc: between 8 and 12 o’clock (when moving the knife to the left)
– reverse (can be working, cleaning or idle)
– gas (by load)
– flat: blade angle and mowing width (more)
– cutting height (to make it easier to mow with a trimmer or to make it cleaner)
– where to go (along the ditch, along the slope of the grass, on the site)
11 o’clock) and to the right with an inclination of the handles to the right (sector
1 hour), and take your time. So that he mows with a trimmer neatly and does not “dig” the ground;
– during work (and turns), do not forget to look around!:
1.To notice the gestures of others, turn off the engine and remove the headphones,
2. So that children, animals, spectators and assistants do NOT come closer than 15 m, because When a metal knife collides with a stationary object in the grass, the trimmer or lawn mower (lawn mower) can be strongly thrown to the side or turned back, and the maximum speed of the metal knife is 10,500 rpm. And he is able to cut off an arm or a leg,
and also, when mowing with a trimmer from under a metal knife, various objects (rubble, glass, debris) can fly out and ricochet.
How to mow with a trimmer (more about the mowing technique).
Engine speed when trimming with a trimmer is set depending on the load on the engine. the thicker the grass and, naturally, the heavier the engine, the bolder you need to open the hole (throttle valve in the carburetor diffuser).
Try to keep the engine operating speed constant while trimming (slightly above average). or less gas. only depending on the total engine load. It is not necessary to completely release the throttle (and immediately accelerate again) with each sweep of the streamer. So the clutch will not burn for long, and it can overtake the edges on the drive shaft. And the overall wear of the trimmer (lawn mowers) increases dramatically.
We find out the parameters of the site before mowing with a trimmer:
(To know which knives to take, how much fuel and time you need)
Installing a diamond blade
Outwardly, this operation does not differ from the fastening of a conventional disk, except that even more attention, accuracy and thorough control are required.
Remove the spool with line, block the gearbox shaft with a special pin or a screwdriver of a suitable diameter, rotating the line container counterclockwise.
We measure the diamond disc to the lower spline washer and make sure that its Landing hole is larger than the diameter of the landing shoulder on the washer. At high speeds, the saw blade can move, imbalance occurs, which will inevitably lead to tool breakage and even injury to the operator or people nearby.
I try on compensating washers alternately and choose the one that fits the width and completely selects the gap between the saw blade seat and the centering shoulder of the lower washer.
We install alternately on the gearbox shaft the lower washer with a compensation ring, a diamond disc, an upper washer and a protective cup, which still partially redistributes the clamping force over a large area.
We tighten the entire resulting package on the gearbox shaft with a nut with a left-hand thread, first by hand, and then with a socket wrench, block the gearbox shaft from below using a suitable screwdriver.
We remove the protective split plastic tube from the teeth and once again check the strength of the saw blade on the gearbox shaft. If it turned out to be reliable, then the trimmer, with the installed diamond disc, is completely ready, both for traditional and NOT intended for this tool, work.

Saw blade selection
We choose a TST series diamond blade, designed for working with wood and plywood, with the following main characteristics:
-
Outside diameter at the tops of the teeth. 216 mm;
Landing hole. 30 mm;
The set includes three rings with the same outer (30-mm), but different inner diameters, that is, they differ in width. These rings are designed to compensate for the difference between the bore of the saw blade and the counterpart on the larger pressure washer.

How to attach a saw blade to a trimmer
The main working bodies of any trimmer are a line spool or a special disc (plastic or metal). A plastic knife, like a fishing line, can cut green grassy plants, with a metal knife. dry grass, reeds and even shrubs. Is it possible to increase the functionality of the trimmer by installing a saw blade on it?
Materials:
- Metal perforated plate (100 mm x 240 mm)
- 2 hacksaw blades for metal
- 4 screws and 4 nuts M5
- 4 washers and 4 oversized washers
From a safety point of view, hacksaw blades should not be completely hardened.
Everything you need to make a nozzle
The most difficult thing in making a nozzle is symmetrically marking and making holes for the knives and the trimmer shaft. That is why a finished perforated plate is chosen.
DIY trimmer attachment
For many summer residents, the trimmer has long become a familiar and almost irreplaceable technique. But it is not always possible to purchase a model that meets all needs. It happens that the trimmer copes with fresh young vegetation easily, but there is a desire to clear the place along the fence or along the access road, and the tall ripe grass turns out to be too tough for the technique.
DIY trimmer attachment
We offer the option of self-production of the trimmer attachment from simple (almost improvised) tools.
Working process:
First you need to make the base of the nozzle. To do this, cut out a square with a side of 100 mm from a metal plate. It should be marked in such a way that there is a hole exactly in the center (at the intersection of the diagonal). To do this, measure a distance of 50 mm from the center of the selected hole perpendicular to the short side of the plate and mark the cutting line for cutting.
Marking the base of the nozzle
Cutting off the excess and we get a square of 100 mm x 100 mm. Now you need to round off the corners a little and drill out the central hole for the trimmer shaft.
Round off the corners and drill out the center hole for the trimmer shaft
Cutting the canvases for metal, measuring 8 cm from each end.We get 4 blanks with ready-made holes.
Cutting canvases for metal
These blanks need to be shaped like knives. To do this, we outline the cut line by eye (special accuracy is NOT required), fasten all 4 blanks together and grind off the excess.
Cut out knives from blanks
As a result, we get knives of the same weight and size, they can be sharpened a little on one side. Now all parts of the homemade trimmer attachment are prepared, you can start assembling.
Everything is ready for assembly
We put a small washer on the screw and insert it into the corner hole. We put on a knife from above, Positioning the sharpened side in the direction of rotation of the trimmer shaft. Next comes a large club and a nut that is NOT tightened so that the knife rotates freely. Support the other 3 knives in the same way.
Securing the knives
The end of the screw must be riveted so that the nut DOES NOT come off.
The end of the screw must be riveted
The attachment is ready. It is installed with nuts to the ground and fixed in the same way as the three-blade knife that comes with the trimmer. When colliding with a stone, the knives fold and go inside a little.
This idea was suggested by our regular author Tatiana (Tula region). You can see in more detail the whole process of making such a trimmer attachment and find out some of the nuances by watching the, which she Prepared.
When working with a trimmer, it is important NOT to forget about safety precautions, using any attachments, especially homemade ones.
We suggest discussing this idea in the comments to the publication. Share your thoughts with us and tell us about your successful solutions.
Without taking any of the sides of this sharp (literally and figuratively) discussion, let me show you one of the latest models of lawn mowers from the German company Robert Bosch. It provides both a deflecting knife and an arcuate bracket, which excludes the knife “striking” on objects not foreseen by mowing. I show the general view of the lawn mowers and the knife itself, in two positions. General view of lawn mowers

Good evening everyone!
Exactly three years have passed since the discussion of the “acute” problem for the trimmer. Over the past 1000 days, a clear picture emerges: “Glory to the author. the craftsman, who is conducting an experiment on himself to reach the yield point of the metal from which these knives are made. He has every right to risk his own health. ” Nowadays in stunt films you can often see a frvza. “Do not try to repeat the movie stunts that were performed by professional stuntmen.” The very first article should have ended with something like this: “Dear summer residents. This is my personal experience. If you are NOT confident in your plumbing skills, please do not repeat it. AND THE MOST IMPORTANT. I am not responsible for the operation of the tool, performed in the footsteps of my article. ”
And the last thing. Do I see errors, judging by the photographs, of the execution of this tool. Yes, I see, and a rude one. Look closely at the plate, which is the carrier for the four knives. Look carefully at the far RIGHT hole in the photo.
Alas, the author of this device does not even suspect how the hole for the shaft should be made.
I inform you that the distance from the hole closest to the edge of the plate to the very edge should be NOT LESS than the diameter of the hole itself. This truth is learned by mechanics students NOT later than the second year of the institute. What do we see here? A thin isthmus resembling a narrow PEREKOP, making a peninsula out of Crimea. This is a priori the place that is weak in this design. it experiences the same loads as other knives, and “Perekop” there is very thin.
Where it is thin, there and.
I would like to hope, and quite sincerely, that over these three years this isthmus has NOT undergone loads comparable to the yield strength of this metal, but rather the alloy from which the perforated plate is stamped.
