Long or Short Air Cleaners What's Up?

Why are there 2 lengths of air cleaners? What were the short ones used for and the long ones? Lowboys? Thanks Brandon.

I believe the short ones were on lo-boys.

I've been told that the long type is used with the vertical exhaust tractors and the short type with the under slung exhaust. Maybe Jim Becker can set us straight.

There must be something to what Donny is saying. I have 5 Cubs, one with the vertical exhaust with a long breather. The other 4 have the horizonal exaust and have a short breather.

Makes sense to me. I guess that's why I was thinking lo-boy.

I just found this out too, Because it was in better shape and already newly painted, I used the air cleaner off my older Cub with the vertical exhaust for my newer Cub with the underslung exhaust. WRONG, I didn't realize the difference until I tried to put the original (later model) cap on, it's different also.

I fixed the correct one, painted it up and replaced the wrong one before I was nabbed by the correct police. I don't know why the exhaust would make a diff' but like you guys said, maybe Jim can educate us.

Tom,

The reason for the underslung exhaust was for clearance under trees, etc. The air intake was shortened at the same time for the same reason.

Yeah, like George said. The tradeoff is to keep it higher to reduce dust intake vs. lower for clearance under tree branches. As far as I know, it was changed the same time the underslung exhaust was introduced, at serial 185,001.

While we're on the air cleaner topic...On a couple of early 1947 Cubs I've seen the WIDER-FLATTER breather cap (like the ones shown in the Cub Photo Archive)...Yet on ALL the other Cubs I've seen, they have the smaller "mushroom" breather cap...or the Donaldson Pre-Cleaners?

A lot of the tractors in the Photo Archive are pre-productin tractors. On close inspection of a lot of them you can see other differences. I imagine they used whatever was conveniently available when the pre-production tractors were built, which was probably dierctly off of some current production machine. By the time production started, they had probably spec'ed the one we commonly see.

Later on they made the change Tractor Tom commented on.
