Hi everyone, I changed both air filters on my Grasshopper. I read where a dirty filter is better than a clean one. Could this be true? I can't hardly believe this.----Cambre

You know, when we only had books and magazines for reference, what was printed was pretty much on track because there was an author that had done some research . But this computer era has changed all that and what we read is more like what we would hear from a group of ignorants setting around a table telling a bucket full of " I thinks ", so I suggest you just go ahead and confirm what you can hardly believe.

Thanks S C, I read this on the forum. I agree with you. thanks

I don't think we have to sit around and hear from a group of ignorant setting around a table telling a bucket full of " I thinks ". Refer to the or your owners manual and get the recommendations strait form the manufacturer. If you don't have the manual you can download the PDF file/manual on your computer by going to the mower site and review it online in the engine maintenance section.

That owner's manual is hardly an unbiased opinion but go by that if it makes you happy, even if they say buy a new one every 10 hours. I've run equipment that needed the air filter system serviced that often but they were made to service for little to no cost.

Yes your correct the owner's manual is hardly an unbiased opinion. Its fact from the manufacturer. The service interval for air filter replacement for my primary air filter is 250 hrs and the safety filter is replaced at 500hrs. Now that's not to say I don't check the filters every 50 hrs because as the manufacturer notes that should be done more frequently under extremely dusty and dirty conditions. As far as little to no cost 40.00$ a pop to replace mine.

It is obvious when a filter needs changing by looking at it.. Dusty conditions will speed up the need to change obviously.

My 2 cents: Its true up to a point. The captured particles in the filter cause finer particles to be caught compared to a clean filter, until its so full that airflow becomes restricted. Its academic, really, a new filter cleans the air sufficiently to meet OEM specs. To me it means don't change out a filter too early, but also not too late.

at least you know it's working.at something like $65.00 for the one on mine I put the air hose to mine after each cut.seems to work pretty good....russ

The Briggs operators manuals for my former 26 HP ELS and current 30 HP Commercial Turf engines say to tap the filter to remove loose dust.
The Hustler/Kawasaki operators manual for my FX730V engine says to monitor the airflow meter and replace both filter elements when the meter indicates to do so, and to NOT shake, tap or blow the filter elements to clean them up as the accumulated dust causes the filters elements to catch smaller particles. The Kawasaki has a Donaldson two stage HD filtering system and Hustler adds an airflow meter.
My Hustler X-ONE is a rear discharge machine and is still on the original air filter elements at 275 Hours. My Scag Tiger Cub with 200 Hours on the Briggs Commercial Turf engine is on its 3rd air filter element, but this machine has a collection system and is very dusty during operation. I tap this filter to remove the loose dust and I replace it when the interior element starts to lose its bright white color. I wear goggles and a dust mask while operating my Scag.
