No load rpm


Recommended Posts

Most garden tractor engines with mechanical governing have roughly a 7% full load to no load accuracy. A 3600 PRM engine generally has a 3850 RPM no load. It's not engine speed you have to contend with on a mower, but mower blade tip speed which is considered safe at no more then 19,000 feet per minute. I did a post on this a while ago.
