I've been riding my Grizzly through mud in the ditches by my higway and on the edge of my 3 acre pond and never really needed 4wd yet but i've used it a lot just to use it. I've went over a big Pine Tree in my pond and it almost touched my floorboards. I just put it in 4wd differential lock and crawled over it easily and there was mud all around it. It's just freakin' awesome! It's rides so smooth and has all the power you would ever need unless you're crazy and need more. My neighbor ride a Honda Recon 250 and I can keep up with him on my tight trails easily. One time he got stuck in the sand on my trails and I had to get a cable and pull him out. The Grizzly had so much power it started pulling the front end up and it would have pulled it over. Everytime I ride my Grizzly everybody stops and looks hard at it. ATV riding is very popular where I live. Everybody has a Honda Foreman 4x4. I just wanted something different and I got something so much better than a Honda Foreman 4x4.
