For years we had a Giant Vac Classic model 52 blower with an 8 hp motor. The machine worked great. Needed another blower so I went out last spring and bought another Giant Vac Classic model 52. Paid about $550. This machine does not work as well as the old one. Doesn't roll as well and most importantly won't move as many leaves. My ten year old son noticed the difference and commented. I called the manufacturer and they suggested having the RPMs checked; however I think the engine runs just fine. I plan to do this, but who makes a good inexpensive machine on wheels. I really like the old basic Giant Vac Classic. I'd like to sell this one and replace it - any recommendations in the $550 price range and about 9hp. I saw a Billy Goat, but didn't like the chute and having to add a plastic nozzle for forward blowing. Thanks for the recommendations.
