I just scalped my Buffalo today and was cringing to do it but it had to be done, I have been cutting it on the highest setting on my ride on for a few years now and if I dropped it one notch it would scalp. I used my Honda push rotary mower which has alot more height settings and went over it a few times dropping it a notch each time till I thought was ok It's not as spongy now and should be ready for the Scotty this season. Can anyone recommend what's best to use sand or top soil to fill in the gaps and when is it best to get the Scotty on the field and do some work. Any tips would be greatly appreciated as this is new for me and I'm not someone who like to scalp my lawn, the neighbours must think I have gone mad.
