I have one. I got it last Winter as my heavy-handed ground man kept breaking with wide, plastic rakes.
I had to lessen the curve of each of the tines, they had too much 'hook', it got really grabby with the lawn. One tine at a time, mini vise-grips, gentle partial un-bending.
Now I absolutely love it, much improved, and that's great because I sorta hate raking, but as you say, TreeVet, ya still gotta take pride in it, and as Lawn Shark says, ya gotta keep the gravel out of the mix, and as
Bermie says, flick it ya freakin moron or I'm comin after your sorry a$z with this MACHETE!
