I have a 2002 Suzuki Kingquad 300.. with a hand shifter welded on. it's a beast.. i have yet to encounter anything i couldn't pull around.. I have a plow on it.. works great.. never had a problem moving the deepest snow we have had. I use it to pull my steel boat lift out of the water. It has a low gear and a super low gear.. i used super low to pull a non-running snowmobile up a giant hill on dirt / grass. thing is perfect for me.. it's light.. i have gotten it stuck in the marsh when the wheels sink.. i can lift it myself and ghost run it to get it out.. every time so far. it's just a 300 but it's plenty fast for me.. on the open ice it can get up to 50 ish.. i use it to launch my 15' boat.. love it. had it like 5 years.. got it for under 2k.
