Is this not the dumbest most restrictive air filter design?

Oh boy…


Anyways, i was going to add that my svl75 and m59 and m62 did not come with these RESTRICTIVE filters.

It’s absurd some dont want to think covering up parts of a filter is not the least bit restrictive, even in a pleated cartridge. I’m absoluty sure it’s engineered for it, but why? It really does make cleaning it out harder too, especially at the bottom.

Oh boy is right. Change it out and put a filter on that doesn't have the guard on it. You could probably replace it with a filter that is 1/4 the size of the one that's on it now.

other than visual, how have you determined the "restrictive" air filter design you describe impedes the volumetric efficiency of your engine? or is it just a visual opinion?

A guess on my part but if it pulls air in from the bottom area maybe that creates some turbulence that the blocked off area prevents. I’m sure it’s there for a reason, it just might not be a good one.

Try this. Open your mouth wide and take a deep breath. Then, with mouth still open, close your teeth and take a deep breath.

Report back.

Without a sophisticated lab or flow cage, we’re still able to make assumptions on life experiences. We know air doesn’t flow good through solid material, if it did kubota would have just put a metal sleeve on the filter without the holes.

Did none of you ever take your toys apart as a kid? My room was just a mess with disassembled toys, some hooked to each other. I remember when I figured out that a small electric motor was also a generator. Thought I was big time hooking up a motor to another to spin it to light up a small led. Lol.. my parents thought I was going to be a genius, lol, so one Christmas they got me a Vic 20. I was about 10. I’m sure some of you know what it is. Within a week it was in pieces. I had no idea what computer was or why you’d want to sit in front of it, but was curious how the keys were spring loaded.

nothing wrong with curiosity or speculation

Which could be, some filters have fins at the bottom.

Typically, it's to keep the filter media from being crushed when installed. It's cheaper to make them that way instead of a thick and glued design. I bet there's an inner filter used in there too. Does that mean you're going to leave the inner filter out for sake of restriction too?

How much hp does your excavator make? I've seen air filters in 300hp cars with less Sq inches of filter material. I don't think your excavator is being choked out by that filter.

A cheap filter may have more of an open design but may let much more dirt pass to the engine.
