I contacted two dealers about a snowblower for my 2014 Brutus HD/PTO. One has a couple of snowblowers (new) from 2014 and the option to order one from the factory 2016. I'd save about $700 by buying the 2014. I Googled around a bit to see if I could figure out what differences their might be. I asked the dealer (sales) as well, he was sure and said he'd check, he did say that he thought the newer ones are belt drive (I'm assuming he meant they replaced the chain drive for impeller/auger with a belt or two). Anyone know if they made substantial changes during that time frame? Thanks all! Hoping I haven't broken some protocol here as a Jr. member.
