I recently purchased a '07 King Quad 700 to plow my driveway and parking area. Since I'm pushing the plow I want the maximum power transfer to the ground so I normally run with the front differential locked and the trans in low gear... If I understand the system correctly, this should lock all four wheels (i.e. all four wheels turning at the same speed)... I've been high-centered in the snow several time now and I've noticed that my front left wheel never spins from loss of traction (and it definitely should be if its getting any power at all)...

What gives?? Do I have a problem with the diff lock system? Are there any troubleshooting steps I can take to try and determine what's wrong?

Any help would be greatly appreciated...
