We harvest as many leaves as we have time for to make compost.
I use this Agri-Fab POS I got at Tractor Supply to pick up leaves.
The second season one of the blades on the fan came loose. I got it shut down before all hell broke loose. By then it was only connected at the hub. I rewelded all of the blades and it's been working for 7 years now.
The pile on the left is what's left of 2018 composted leaves. The one in the middle is last year's leaves, ready to use. The little one on the right is the start of this year's pile. It'll be about 4'x4'x20' in a couple of weeks.
