Which models offer the switch between 2wd and 4wd on the fly?

I wanna buy a Rancher but would like to be able to switch out of 4wd when not needed.

Thanks

 

Ok the 400 auto rancher you can the 350 rancher you cann't unless you installed the warn 4 2 4 kit (they work great shift on the fly). The 500 foremans and the 650 and 680 Rincons. If your going to just trail ride then the 400 is good, but not if going to put mud tires on it, has no low range.

 

I believe only the Rancher AT has the 2wd/4wd selector. The Warn 424 is a replaceable front drive shaft that provides a front axle disconnect and seems to be very popular for those who have the Rancher 4x4 or Rancher ES 4x4.
