I would like to operate a european lawnmower which runs on 230v/50Hz. It is made by Bosch and they do not market it in USA. There are many other rechargeable models which are not marketed in USA but are very nice environmentally friendly machines.

The mower model is Rotak 43. It is a mains driven model. I am told by radioshack and other electronics store people that using 60Hz supply on 50Hz motor will burn out any electronics and motor may just not turn and may even burn out. The power is about 1600watts which is around 2HP. I have tried just a step-up transformer and that does not work and I presume it is because of the frequency difference. Thanks

Just buy a transformer. A big one.

Depends on required amperage.
But I would think under $50 but it is going to be 60 Hz, so the blade will spin faster.
Post the Model number.
Additional:
Is it rechargeable? If so, the unit may have a multivoltage transformer and you may just need to move a wire. If the unit does not have a built in charger, then you just need to buy a charger that will work.
Cool looking mower.
There are converters, but I think it would be price prohibitive.
Who ever told you about the motor dying is correct. MOST motors do not like the phase change. The electronics would be OK although if it uses a transformer, it may die at the 60 Hz.
Good luck.

All homes in the US (or at least the ones I have seen) have 220 VAC 60Hz. If you have an electric dryer chances are that it is running on 220 VAC. So there is your source of 220 VAC. No need for a transformer. Though you will have to construct a cord for it yourself and I don't think any building code allows 220V extension cords to be connected to garden tools.
Most high torque small motor applications use brushed AC motors (also known as series DC motor or universal motor.) Like the ones found in vacuum cleaners, drills and kitchen blenders. These kinds of motors are more or less universal in that they can operate at 50Hz or 60Hz. And in some cases on DC current too!
Brushed AC motor will not run slower on 50Hz or faster on 60Hz either. It will run at the same speed on both frequencies. The only difference is that at 60 Hz the motor will generate a bit more heat because of marginally higher iron core loses at the higher frequency.
Check the S/No. plate on your mower. I bet you it says 50/60Hz on it. Just run it on the 220 VAC already in the house and you will be fine.
How did you manage to bring it to this side of the pond anyway? I've been trying to import a norcool corner fridge for ever now and can't find any cost effective way of doing it.
