I want to run my 82v dc mower on 110v ac help

We don't have much to go on here. How about the make and model of the mower.
Alternatively, how much current does the mower require?
A transformer, a bridge rectifier, and a capacitor might do the trick.
Are you going to connect the mower to the mains with a long extension cord?
Other schemes may be possible, but I'm worried about your safety.

 

Where did you obtain a 82v mower?
Self built, Or was it a battery operated version?
If you do convert using a transformer, you would need to re-reference the secondary to earth GND.

 

A transformer, a bridge rectifier, and a capacitor might do the trick.

A transformer with an output of about 60Vac would give the desired rectified voltage, but it would likely be a large and expensive transformer depending upon how much current the mower takes.

 

Or an 80v secondary with no capacitor, not needed for a motor load.

 

An alternative would be a Treadmill controller, either the MC-60 or the MC2100, often available from free kerb side pick up or local on line market place.
Either way, important to feed from a GFI socket.
