After further research, as well as some of the comments in here, I've decided to buy it, it' s only $100, and if it turns out to be a piece of crap, so be it. I have no concerns about my JD being able to pull it when full, becaue I pull my 5 x 8 utility trailer with it on my property, and it doesn't fiz it a bit.
I was at TSC just the other day, and around here their generic brand is Agri-fab, and their 42" sweeper sells for $350.00.
I was just concerned that a 32" would mean it would fill up quicker, having a smaller hopper. It's too bad they don't make these things to disengage when you want (e.g. if you have to cross a gravel path etc). For the price they sell these sweepers, you'd think they would do that....how complicated would it have been to design it that way ?!
