Not really. It’s basically manufacturers moving the same components around and calling them “all new” models. Creating “affordable” commercial lineups out of estate mowers, resulting in increased failures. Mower models that shouldn’t even exist, because the manufacturer want to slice their pie into even smaller pieces. To answer your question: •Don’t touch a Spartan. •The Toro is a nice mower, with a fantastic cutting deck. When people mention Exmark, it’s a Toro chassis with an Exmark deck. The Toro deck cuts nicer, so stick with it. Which Toro 4000 model are you looking at? Do you have a Toro dealer you’re working with? Do you have any other mower dealers close by? What size and type of property are you mowing?
