Hi

My lawn is bumpy! When I mow the grass it is like mowing a newly ploughed
field.

I tried a roller for the first few years ( filled with water/gravel ). No
good

I have tried top dressing, every summer for the last few years, a mix of
sharp sand & compost. No good.

The soil where I live is clay, with a few inches of 'topsoil' added by the
buliders. (It is beautiful clay, creamy, heavy)

I use an electric rotary mower.

I dont want to use a rotavator, it will just bring up the clay.

Help & advice please ?????
