I need help making a spendy tool purchase. I need a good heavy duty garden shredder-mulcher for seasonal clean up for a 2 acre garden and orchard, something that can handle woody stems from shrubs, cornstalks, tomato vines, berry canes, lots of leaves and reeds. Something that can handle a lot of it, and not clog itself up on fibrous things like cornstalks. I would really appreciate recommendations for a good gas powered one, with a good starter so I'm not repeatedly pulling a heavy flywheel when I have to start it (hate that). I've had an old craftsman from OSH and have grown to loath its nasty choke, uncooperative flywheel and annoying habit of clogging after one-half of a cornstalk. Ideally under $600, but I'll consider a higher priced one if it's got multiple rave reviews. Thank you!
