The traction Booster on these (Both) works the same, only the WD-45 has a gauge...as you get used to it, you don't really need the gauge... There is a large coil spring under the transmission that is built into the hitch and the PTO shaft goes right thru it.. As the load on--let's say, an AC Plow-- increases, that spring starts to compress.. The lever on the LEFT side of the steering wheel is the Hydrolic lever.. the Traction Booster is built into the system, when the settings on the Hydrolic pump and linkage attached to it are set for "Traction Booster". Under a darned good load, raising the Hydrolic lever a certain amount will lift some weight off the front of the tractor and improve traction.. I say "certain amount", as the amount depends on how worn the plow shares are, and the plowing conditions.. Good Shares and Hard plowing conditions and the front may be lifted off the ground with the Hydrolic lever all the way DOWN..! In easy-plowing, but wet conditions, you may need to lift the lever more than half way to get weight transfer.. This was a Very Good System..and will work with an add-on snap-coupler 3-point hitch, too...! Ron..
