Looks like my post disappeared. If you read your manual, you will see that the filter is meant to be removed daily in dusty conditions and cleaned. It isnt like throw away car filters, it is semi-permanent. You owners manual will or should describe how to remove the outer filter (some tractor have an inner filter and the housing has to be built for inner and outer filter, you cant just put one inside the other one) dump the dust cup, unscrew the wing nut and pull out the outer filter, tap gently on the tractor tire to remove the excess dirt from the pleats. If you have compressed air, blow the dust out by blowing on the outside of the filter, blowing out each pleat, then reinstall being carefull to make sure it is seated properly. The outer filter should last several years if you dont damage the seal or tear the paper or get it wet. You dont need a high dollar K&N filter kit, it already has a cleanable filter designed specifically for the tractor operating conditions meaning dusty conditions and grassy fields. Some higher end tractors will have the same litttle gizmo as your car with the little green/red element that registers restriction, when the filter needs cleaning, the device trips to red. Clean the filter, push the reset button on the end and watch for it to turn red again. Excessive black smoke is a good indication that your filter is really stopped up bad and needs cleaning.
