What makes you think so?My Kioti CK35 manual in front wheel drive is only powering the left wheel???
An open differential applies equal power to both sides. If one side has less traction, that wheel will spin, and it will appear that the other side isn't getting any power. I reality, both sides are getting equal power. It's just that one side doesn't have traction. It's just like one wheel on your car spins on ice.
