remember you want to be searching for "levelling lute" or "soil spreader"
but depending on the size of your lawn.... but I bought this one from bunnings and seems to work well enough, but obviously a BIGGER one will do the job quicker. Or if you're handy enough you can just make one.

the have another one thats about half the price but seemed really crappy when I saw it in the shop vs the wooden handled one. plus its bunnings, can always use it and take it back saying it was crap and get a refund. I think there are some other aussie made ones out there but price was higher, but being a bigger tool would do the job quicker/more accurate.

other then that can always just bolt/weld some angle iron together and make your own
paddocks and large area's seem to just tow a pallet or bed frame around
