Bosch Rotak 43 (0,600,8A4,300) reviews

Second season mowing, mowed tall grass with weeds several times – managed! Clean mowing around the edge. And last fall also worked as a garden vacuum. The blade is steel with notches that not only mow, but also quickly collect leaves from the lawn into the grass catcher box.

I bought this lawn mower six years ago. I use it from May to the end of September on a plot of about 12 acres. The plot is not ideal. And trees, and bushes, and even there are some stones. I have bought new blades twice and usually sharpen them with a grinder. I only put new ones in when the old ones are completely dead. I don’t take much care of the mower, I clean it after I cut the grass and that’s it. I never wash it. It sits outside. I’m waiting for it to be covered. But. It’s just an awesome machine. The previous one (not a Bosch) lasted 2 years. Now that’s a good

Disappointing. The price is high, but it did not meet any expectations. Before it was the cheapest Chinese mower (for 1500 P), and it worked longer (three years).

I use it for the second season! Also works, now I use only up to 1 cm, very cool. Digging area is 4 hectares.

Small compartment for grass clippings! I don’t like the saw, mows grass up to 10-12 cm better, it just crushes it on top, so trimmer first. Always watch the wire.

As the girl below says mowers, but the blades are really dull, if you decide to buy an electric lawn mower, find out where there is a service and give the opportunity to sharpen or buy new blades. I do not recommend sharpening the blades yourself at home. The slightest imbalance and fly bearings, the repair of which will cost half the cost. P.S.S. I put the cost of knives about 800 rubles, see dealers Bosch. P.S.S. The 2015 season is over, flight is normal, put new knives at the end of the season, the price of 1100 rubles. Rating changed great, really worked hard in 2015.

Yesterday I bought, reassembled, re-turned the blade, scrolling the knife with my hand, it rotates very tight. Who has such a lawnmower, tell me, is this normal? Maybe there is a brake mechanism? Plugged it in, it works, but I’m afraid to start working the grass so I don’t burn it. Please convince yourself and let me know!

Colleagues, buy a voltage regulator and an extension cord with the right section of wire. Very good lawn mower, in operation for the third year, the lawn area of 400 sq. m. My neighbor has a Rotak 37, the device is already 6 years old (!) All works perfectly. Before mowing, I bring a knife with a grater. Support was a must!

Reliability is top notch! Powerful. Light weight, unlike gears counterparts. Even an elderly person can handle it. With a little skill it also mows very tall grass, both over hills and over bumps.

The grass catcher box is almost useless, it gets completely clogged up while mowing a strip of 30 m and the grass height of 15-20 cm. We use it only when mowing for the first time in the season, and then we mow without the grass catcher box. When the grass is very succulent, the blades quickly get clogged with grass, and we have to clean them constantly. Koshu had a garden shovel with him to clean grass and soil off the floor and blades. I adapted a wire to raise the tailgate to different levels – this adjusts the grass and the blade is less clogged.

The mowing area is 12-13 solid lawns tomorrow. This is my third such machine. I will not mention the names of previous companies for ethical reasons. The first mower was petrol, but the engine failed in the first season, the second – the analogue of a well-known Japanese company, the camp came off the second year, and worked for two more seasons until it was completely dead. The same unit has been working like a tiger since the fifth (!) season! The main thing is to sharpen the knife carefully and not to let the stones, wire, and other hard objects get under the knife. Main tip – keep an eye on the wire! Long story short, I am happy with this device like an elephant!!! :) I realize that things don’t last forever. I’m thinking of buying a new one at the end of the season and keeping it for parts. Good luck everyone with the Bosch Rotak. ====== Contact. Summer 2016 season is coming to an end and the machine is still in use.

Excavator-loader EO-21101 - description and properties

Mows well and fast. If it’s not clogged, all the grass goes into the grass box, but it fills up quickly when the grass is high.

Simple – the woman handles without any problems.

After a year of use it suddenly stopped working. Once a week I mow 10 acres of lawn.

The service said to replace the stock and the motor! – 9500r. Good thing I kept the warranty card, promised to replace everything for free, and advised to keep an eye on the blades, as with blunt knives the load on the motor increases. With normal use should last 7 seasons.

When you start the mower, it doesn’t mow, it shreds the grass. The cutting height adjustment constantly jumps to 7 – in principle, we like this height, but if we had to cut shorter, it would be annoying.

We are using it for the third year, no complaints. But we should clarify – we have a perfect lawn, we do not run for any mountains, we do not cut the shoots…

Powerful. Easy on the move. Excellent height adjustment features. Wide grass catcher box. Works almost 4 seasons.

Engine protection is not well thought out. Grabs small grass in front and under pressure drags it to the ejector. Engine. The blades are not as hardened as they say on the manufacturer’s website. They are sharpenable with a regular file. Tried to find a new knife – not easy. Wheels were hard to turn after the first season, everything was solved with regular WD.

Last week I noticed that the lawnmower became very noisy, the blade spinning as I decided to brush with great effort. The cross and star screws are used to reduce the difficulty. When I opened the upper housing, I saw a large amount of grass. Clarified. Opened the engine cover, there was even more fluff and grass. Tried cleaning, but it was impossible to get down. Had to remove the letter. Engine. This was a fatal mistake. Hospital belt tension between drive roller e. Motor and blade shaft, very powerful. There is no adjustment. You can see that in the factory, with some special devices, everything is done in the factory. After cleaning and rinsing, began to assemble for good luck, killed two evenings. The engine was mounted at the top and the four bolts at the bottom. I have terrible inconvenience. To make a long story short, I had a lot of troubles, but on the housings of the cooling fan of the postal unit. The engine formed a connection without cracks. The fasteners did not give anything and pulled as much as they could. Had to caulk those holes around the perimeter. Turned it on, it works, but obviously not like the new one. So I took a new Bosch Rotak 37+ trimmer just in case. This is one of those kits from the manufacturer. Tip, don’t try to open up the electric motor, you’ll just kill the lawnmower. Make it work for as long as possible, and that’s the most important thing.
