Now that I've got the tank cleaned out, the Brutus is working well. No speed demon, but I use it mostly for work on the farm (running parts out to tractors in the field, etc.). To clean the tank, I carefully removed the fuel intake/level sensor using a special wrench from Polaris (cheaper on ebay). You can aso use a screwdriver and rubber mallet. I siphoned the fuel out and swabbed the bottom of the tank, Also made a design change...the stock fuel pickup screen is tiny. I spliced one in that's larger (Bobcat part) and is not as likely to plug up,
If you can, get the service manual. It's worth its weight in gold. Lots of information and if you're handy and have a good farm shop, you can fix things yourself.
Anyway, the Brutus is not designed for fourwheelin'. As far as a farm utility vehicle, it's fine. I'm glad mine has the Yanmar engine. The Kohler diesel on later models is supposedly a POS. I got the snowblower attachment as well as I live in New England.
