Just a quick one:

I have about 1.5 acres of 'lawn', the soil appears to be fairly compacted
and so I'd really like to aerate it as it clearly needs doing so.

I also want to introduce clover seed and other varieties as well, so yet
another reason it needs doing.

Anyway, I'd be interested to hear of any ideas of how to do this without
spending hundreds (or more) on equipment.

Any good ideas on building something to do the job perhaps? I have a ride-
on and ATV to tow any such gadget around if need be.

TIA.
