From what My Toro dealer told me, the machines are the same....other than color and stickers. Toro added a few different things...wheels, front hitch, but almost everything else is the same. Thru My Toro Dealer locally, I ordered 5 replacement tines for the ExMark 30" Riding Aerator....and it took almost 2 months to receive them. I thought since Fall is getting close....and we've been getting some rain here in Northern Illinois....I should have a few new tines just in case something happens. This Spring I would have to take a few off after aerating a yard because a rock would get jammed in the tine's hole. Plus I always clean the tines after each day...takes a bit...but it's nice to know that nothing wrong when going into a customer's yard the next day. I will try to get some pictures of the tines and drive chains...will be busy cutting yards tomorrow...but like I said....it should be the same. And any Toro or ExMark dealer should be able to work on your machine...even though its a Lawn Solutions.
