Lower flow rate,,heck even if the 2 quarts of oil flowed through the filter once daily you would be doing good IMO,and Im sure it flows alot more than a quart every hour.
As long as filter restriction would not cause ports to get proper lube should be fine,,not exactly sure how the pressure system in a mower works?
If the filter was removed and housing plugged would the engine still get lube from a splash,would the pump still circulate the oil through the ports just without filtering,,I have no idea??
Like Bert said,decoration,,and like I say,,an added bonus
