Question

How can you tell when your lawnmower needs a new filter

Answer 1

I assume your referring to the air filter.  If it is dirty it should be replaced.  It is recommended that it be replaced every season.  If it has a foam pre-filter it should be cleaned every 25 hrs.  

Answer 2

Oil or air?Once a season

Answer 3

I AM ASSUMING YOU MEAN THE AIR FILTER. DOES THE ENGINE SMOKE? IS THE SPARK PLUG BLACK? IF SO, COULD BE A CLOGGED AIR FILTER. BEST WOULD BE TO REMOVE IT AND SEE IF IT IS PLUGGED UP WITH DIRT AND/OR GRASS. IF IT IS PLUGGED UP, YOU MAY BE ABLE TO BLOW IT OUT AND RE-USE IT. BEST WOULD BE TO REPLACE IT. IF THE PLUG IS BLACK CARBON FOULED, I.E. AN OVERRICH MIXTURE, REPLACE IT ALSO.

Answer 4

If you mean air filter,then simply remove it and run the engine without it.

Has the running of the engine improved?

Yes. you need a new filter.

No. You dont need a new filter.

If you mean fuel filter,bypass it with a short length of fuel pipe.

Has the running of the engine improved?

Yes. You ned a new filter.

No. You dont need a new filter.

Visual examination is often a good indicator.

Failure to replace filters when necessary can possibly lead to recuced performance in other parts of the engine even after the filter has been changed.

Replacing filters ccant do any harm.If you are in doubt and they are cheap ,get new ones.

Me?

I tend to ignore everything until the lawnmower dies then I panic.

Answer 5
