I have an 800 Ranger and it does have some limitations on tight trails. The cargo area does make up for it and it goes plenty fast enough for me. I put a 2 inch lift on it and that solved most of the getting stuck issues.
Country Clipper makes zero turns with a joystick so you still have a free hand. They are a heavy duty mower with large spindles and a flip up deck. Not sure who is the closest dealer to Peace river but Van Braban sevices in Riveare Qu Bar and Escape in RedDeer sell them.
