I had grass accumulate on the chaff screen and saw temps rise pretty fast...hit 285 in no time. 2 Share this post Link to post Share on other sites

Greentored 3,217 #6 Posted January 5, 2022 Super interesting! I did a pretty 'warmed up' K321 last year, and installed an oil temp gauge to monitor one from the bottom. Was surprised to see the gauge barely tickle 150, and that was on a 80 degree day, jerking a plow around the garden. Keep updates going, interesting stuff!

Splash lubed engines tend to run cooler oil, I put a gauge on a 25hp kohler command twin and saw 190 at the filter adapter but my M10s running at 50% duty cycle barely hit 140 1 Share this post Link to post Share on other sites

I was expecting to see much higher temps for a big ol hunk of cast iron. Betting the rod journal is a lot more than 150 though haha Share this post Link to post Share on other sites
