Think about how many times a second that dipper is grabbing oil. Plenty to keep things lubricated and plenty of air movement too. Back in the 60's and 70's my Dad would pull the kids, little and big, with his one lung Kohler. His property had some hills and he would chug up and down just barely above idle. Sometimes it seemed like a challenge to him to see how much he could pull before he had to rev is up a bit. Sometimes he killed it before he could get her revved. He did that for many many years until I took over and do the same. Never had an issue. I'm not suggesting doing that but I am saying that I simply don't buy into the 'must run at high RPM' crowd. I think the running at full throttle is more for cooling the engine 2 Share this post Link to post Share on other sites

Or... On a manual transmission tractor for running implements or pulling heavy. Even the pulling heavy would be marginal to me. I have the K341 on my Cinnamon Horse 1974 C160 8 speed set to 3300 RPM max. That's likely around 14 HP and it does perfectly fine for all I do. 2 Share this post Link to post Share on other sites

Yes, I have two of them in fact, Homelite/Textron 3600W. 1980 vintage. 1800 RPM seems barely above idle when you hear it! 1 Share this post Link to post Share on other sites

I have to exclude my sickle bar mower. I think it would part ways with the tractor if I tried it. 1 Share this post Link to post Share on other sites
peter lena 8,629 #30 Posted January 24, 2023 @John2189 agree with you on that , have always felt / listened to my mechanical anything , like to be running where it seams effortless in its operation , been doing that 40 years . can also appreciate the cooling issue , regularly clean off my engine cooling intake and look around for any related issues . have often stated a running rease on my stuff , always looking for anything related to not working with ease . pete 1 Share this post Link to post Share on other sites

I know the 16 is the horse power, but what does the 5 stand for? the same for my 656 john The xx1's were 1978 and 1979 models. The xx5's were 1980, 1981, 1982, and 1983 models, They all had the shaker plate engine mount and the gas tank under the rear fender. 3 Share this post Link to post Share on other sites
