In this video I discuss the various drive systems you can find on Ariens snowblowers. The trigger lock mechanism is focused on here.
Customer brought this Ariens Deluxe 28" machine in and was not able to shift the left wheel into neutral. Typically the problem is rust and/or a maladjusted spring. This one wound up being rust preventing the splines from engaging with the wheel axle.
