There is most likely a click pin where the wheel hub attaches to the axle. The pin can be installed so it locks the wheel to the axle or lets it turn freely.I just bought the 726 OE tonight for my 76 year old Dad. I also have a 5 year old 726 TE that's very similar. When showing him how to operate it I noticed that both wheels are powered (posi) making it extremely difficult to turn. My 726 TE has only one wheel that is powered which makes it easy to turn. Is there a way of disengaging the posi traction and go to single wheel traction? or is there something wrong with unit?
On my old 2 stage, both axles have the pins so you can choose which wheel drives if you don't want both of them powered.
