Grass trimmer how does it work




















Tapering Tapering is a handy technique that involves tilting the trimmer so that it is at an angle and the leading edge of the line is used to cut the grass.

By cutting the grass at an angle it can create a cleaner and angled look to the fenced edges. Edging Edging is a great way to add some neat touches to the sides of the lawn. Normally this would be done for the grass by flowerbeds or driveways. It enables you to create crisp edges to the lawn by removing any overhanging blades of grass or debris. This can be done with a grass trimmer by simply turning the line so that it is perpendicular to the grass enabling the cut to be made vertically.

This can be easier with some Flymo models that have rotating heads. With most Flymo products, the head can rotate 90 degrees so that edging is easy along the extremes of the lawn. Scything If your grass is longer, this can be a good way to cover large areas quickly.

You will need to swing the grass trimmer in a circular U-shaped motion around you. If you keep yourself in a steady position, you will get a nice and even cut. How To Use A Grass Trimmer: Top Tips The grass trimmer is a versatile machine that can become a very handy companion in keeping your lawn looking its best. Reason for this includes; Close Contact — The most frequent cause of breakage is with harsh contact with something in the garden.

Usually breakages occur when the head is taken too close to garden objects like stones, walls and paving edges which causes the line to snap. Incorrect Parts — It may not be ideal but breakages can be attributed to incorrect parts.

You should check the manufacturers instructions for advice on the correct parts. The generic name for a Weed Eater is a string trimmer, and several manufactures sell models with electric, gasoline and battery-powered engines.

String trimmers are lightweight tools, and they work by using rapidly spinning microfilament string that becomes stiff enough to cut grass and weeds.

Most models feed new string automatically as the old string wears out, dispensing with the need for heavy metal blades that need sharpening. Mechanically, a string trimmer functions much like a handheld lawnmower.

The most powerful string trimmers have two-cycle gasoline engines that use a mixture of gas and oil. When you pull the cord to start the engine, the permanent magnets on the flywheel energize an ignition coil that sends electric current to the spark plug.

It begins firing with each revolution of the flywheel, igniting fuel in the combustion chamber and driving the crankshaft. In an electric or battery-powered model, electric current rotates the flywheel and drives the crankshaft. You have to manually start gas-powered models by pulling a starter cord. Electric and battery-powered models start as soon as they have power.

The engine crankshaft connects to a centrifugal clutch; this, in turn, connects to a drive shaft that extends through the shaft of the machine to the trimmer head. Occasionally adjacent turns can bind and line not feed out but it doesn't happen regularly.

Make sure the spool is seated properly in the head before you screw on the cover. I bought a 2 stroke petrol strimmer today and after a few minutes of strimming, the line stops auto feeding.

When I open the head the line gets caught around itself. I've tried to steps of coiling the line up in the direction of the arrows and tightly but still it keeps happeningp?

Any thoughts? Everytime I weed eat the string breaks. I have to stop take the string out and put back in. I hate weed eaters. Thanks Geraldine. Some vegetation can be very tough with stringy fibres and a trimmer won't cut it, although a brush cutter, maybe one with a cutting disk, will do.

The leaves of cordylines are really awful and will tangle up a trimmer line and wrap themselves around the head. Thankyou Eugene. The string on my flymo trimmer keeps flying out.

Maybe the Elephant grass is too strong for it Will also try and tie string tighter. I have a Ryobi trimmer but the silly string is stuck! Husbands shouldnt die before wives!! Geraldine South Africa. The mechanism that releases the line if it atofeeds or line can be fed out by bumping the head may be damaged. I figured out why the line was hitting the guard. My trimmer's guard lost two of the three screws holding it in place, and it made the guard hang just a little bit too low.

Bought a couple screws from the local hardware store for a few cents, installed them, and I don't dread doing yard work anymore! Hope it helps somebody in the future! Thanks for the help! Does the string auto feed? I presume you've tried to wind it tight and even as suggested, so excess line doesn't fly out and get cut off when it feeds. Have you wound it in the right direction around the spool? Usually there's an arrow indicating which way to wind. Also use a heavy enough gauge of string as recommended by Stihl.

Light gauge line wears and snaps quicker. The only other think I can think of is that something's gone awry with the feed mechanism. Hi Eugene: Good article.

Question: I have a heavier duty stihl. The lower string breaks quite quickly. It doesn't matter if I am going fast or slow, in heavy vegetation or light. I end up with a lot of the lower second string still on the spool, when the top is gone, and mostly, I'm cutting with one string.

Two strings would be better. I haven't found anything obvious that would be cutting the string. What if the line points upwards, and hits the guard?

The line is already shorter than the cutter can reach. If you find that the line is always flying out and hitting the guard, it may be too loosely wound on the spool. When winding, try to keep it even plus wind tightly as shown in the video. You could use a brushcutter. These cutting heads are suitable for cutting brush growth, i. I don't know how effective they would be on grass and it's unlikely they could be used up close to herbs.

Hi there. I would like to know if there is any trimmer I can buy without having to go through strings. Do gas ones have these things? I never had a gas trimmer outclass my greenworks at all. Quite the opposite. When they figure how to make a battery powered one perform like a 10 amp corded trimmer with run time of gas, then gas trimmers will be a dead market. Hi John, I never thought of doing that because I've never had trouble with binding.

Nylon is used for trimmer line because of its two desirable characteristics, high resistance to abrasion and low friction coefficient i. If the line binds, it could be because the turns on the spool are wound too closely together. When winding, I try to space the turns widely rather than packing them closely together. However try to pull the line tight as you wind the spool to prevent excessive line feeding out as the head spins.

I don't know whether oiling the line would be effective but you could try using a silicone spray which would be less messy than oil. However it's likely that centrifugal force would just throw lubricant off the coils as the head spins. Hi Len, as outlined in the article above, try to cut with the tip of the line, don't bury it in vegetation or let it slap off concrete.

Don't let it wrap around shrubs and basically just ease it into vegetation when cutting. Thin line will wear and quicker when attempting to cut dense vegetation with an electric trimmer so just take it easy with it or try using a thicker line. I have used 2. Thanks Jodah, it can be frustrating when the line breaks, which is often due to over zealous use of the machine. Watch out for shrubs and trees also, the line can easily strip bark and stunt growth.

This was a very useful article eugbug. It drive me around the twist having to continually replace line in my trimmer. I will take your advice and take more care to only use the cutting tip of the line and move into grass slowly a little at a time.

The article is well written and easy to understand. It is well illustrated with photographs. The author is very sincere and dedicated. Fabulous instructions and photos. Best web pages I have seen showing so much detail, of tremendous help to me. Thank You. Hi John. Thanks for the comment.

We don't have to worry about grass cutting or trimming yet here.
