Hey folks....I just got to my "barn find" a pristine 1964 !st series Ariens model 10ML60D...this blower still has white paint on the muffler! I did a complete service and got her running.....just had to pull the bowl and wipe her out....fill with gas and adjust the carb....I have some questions.....Scott? Jack Mels? anyone else. The axles seem to have some kind of differential behind each wheel. when I tried her out this afternoon, one wheel would spin, then the next. Is this just on the first series machines, cause I've never seen it in all the later 10000 series I've played with. Second...I'nm not impressed with the traction on these old 10000 series ( or the first series)...what would the membership say....chains or snowhogs? third question.....what do I do with this girl...all original( except the pull cord and handle). I really don't want to be a collector.....and I certainly am not going to sell her to the average shmo who just wants to clear his driveway.
