Rod failure
So the time has come for us to cut grass on the hay, I looked at the weather forecast, it just turned out a window in a few days without rain. Let's mow, and then there was a nuisance - the barrels broke the bar. My braid is inexpensive, Chinese, called "Taiga." The declared power of the scythe is 2.2 kW, and it seems to me that there is definitely no less.
The rod broke just in the place where the handle is attached, the rod is made of a thin aluminum tube, and I worked obliquely for a long time, it’s far over 5 years.
What to do with the barbell? It is necessary to mow, to the city 30 km of impassability, it’s so easy not to run to the market. I made such a connector from a piece of iron pipe, cut it along and pulled it with bolts and nuts. Holds well, very tight, a little put on weight, but I do not feel it. Everything works fine.
Knife
Do not try to repeat, dangerous!
There was one more trouble, I got on a piece of reinforcement sticking out from under the ground, after that the knife bent great, but the gearbox withstood. By the way, I hit many times, and on bricks, and on glands, and on trees - the gearbox never vomited for the whole time, which is very suspicious for an inexpensive braid, probably lucky with accessories.
So, he made the knife himself, cut off the blades of the old knife and instead of them welded his blades, which he cut from the old saw, the thickness of the metal is about 2 mm. He made the bevels with a grinder, put a shield, so that if something flies, he does not chop off his leg.
The blade length of the old knife is 6 cm, and the new 9.5 cm, the radius of the new knife is 14 cm.
The knife turned out to be much larger in diameter than the standard one, the scythe pulls it without problems. I can’t get enough of how she is mowing now! Turnovers at work no more than 20-30 percent of the total, the knife does not stop, does not wind anything, also a large grip.
I mow in both directions, each swath is half a step, so now I am running along the hay. Also, with this welded knife, he hit trees, stumps, wire, nothing fell off. It seems to be perfect, to the blade, not like a regular one from plasticine. The radius of the resulting knife. Also, thanks to the shield, which I had not used before, the hay folds perfectly, and it does not interfere with work, rather, on the contrary, there are less chances to drill into the ground.
And he also mows better because the blade is straight, and in the standard one it was mowed, it jammed the grass, not the angle of attack.
Reason for winding grass
As soon as I bought a scythe, but I bought it second-hand - constantly wrapped grass on a knife, began to understand. It turns out that there is a shield that stands on the gearbox, and so, there should be a minimum clearance between this shield and the knife. Put the washers, removed a large gap, now the grass does not wind!
Mode of operation
Kosh, I am always in the same mode, at stable speeds, I do not understand these idiots who constantly torment the motor with their periodic gassing. Do you even understand that this way the engine wears out faster ?? Pressure and temperature jump sharply in the cylinder, and high revs are not good for the engine, although not constant.
At the moment, I mowed at least 50 acres per day and it's all pretty fast. I work at stable speeds for at least an hour, at least two, even three, the engine does not overheat! It can overheat if it works stably and for a long time at 70% of power or more, or maybe less, but if the piston is killed.
That's all that is interesting, ask. I apologize for the quality of the photo, something happened to the phone, and lug the camera down.
