Just wanting to get some opinions. I have a Troy Bilt Pony that I have had for 20 years. It has been a great tiller. But I have read that Troy Bilts aren't what they used to be. I think I would stay with a rear tine and maybe one a bit bigger than my Pony as I have a medium sized garden (3500 sq ft or in that area). What do you think is the best out there right now?
