Anybody know where I can get lawnmower blades sharpened and general repairs done

Sansai area if possible

A good place for lawn mower servicing is Montri, the last shop on the left, on the superhighway frontage road before the Chotana intersection, heading from Mae Jo turnoff.  Another good shop to service your mower is on the east side of the river, north of Rimping Condo, on a bend in the road.  Can't remember name of this shop, but there are tractors & trailers parked outside.  Can't miss it really.

Buy a grinder for 500 baht and you can do it yourself in less time than it would take to get the mower to the shop.

ME Smith has it right, I have used the first shop he mentions many times. A 500 baht grinder will do not do many good repairs.

You could also do the same with a 20 baht file. It's not rocket science.

The wife does ours.

Unfortunately the 500 Baht grinder will neither do repairs nor will it sharpen a cylinder mower blade should the op be talking about this type.

How does it it go give a man a fish or teach him to fish.

If it is a normal mower it will save running off to get it sharpened, yes it won't do much in the way of repairs. But then some people have no idea how to help themselves.
