Kohler Courage Single cylinder engines are called bucket engines for a reason. because when you're done tearing them apart to find the failure, you have a nice bucket for the parts. The issue is oil. The oil journals on those engines are undersized and vertical..and when you use old oil, contaminated oil or run them low on oil, the rod bearings quickly wear out because it can't pump the oil upward and you end up snapping either the crank or the connecting rod. They're a cool design over the Briggs singles because you can get to everything without removing the head...but I run from them anytime I see them because you never know how they were taken care of. All that aside, Kohler Magnums are great, as well as their Command series. And courage series vtwins are relatively safe also. I prefer Kohler over Briggs most of the time for twin cylinder/vtwin, and briggs over Kohler for single cylinder stuff. I flip riding mowers for a side hustle for the last 5 years.

r/lawnmowers on Reddit: Why are Kohler Courage engines so bad?
April 17, 2024 -

I have a 21 hp single cylinder Kohler Courage. From what I can tell, the main issue with these is a cracked block which can be prevented. Are there any other issues that can be prevented? And how long could I expect it to last after lock titeing the cover bolts along with diligent maintenance? Thanks

June 2, 2017 - iirc, the v-twin courage engines are based on the Kohler command and are very good design. The single cylinder engines are said to be less reliable.

is kohler courage that bad compared to the command - TractorByNet
March 21, 2006 - If a 1000 series unit is the right tool for you (mowing maybe an hour every week, and never cutting more than a few inches, or pulling hard up & down hills while mowing); the engine is likely well matched. On the other hand if you need that thing to run several hours at a time; plan to torque it hard, or you expect 2000 hours out of it; well, I wouldn't try it with that mower or that engine.

Common Problems With Kohler Engines (According To Owners) - SlashGear
February 11, 2025 - However, the overall opinion was pretty low for Kohler engines, with most mechanics recommending Kawasaki engines instead, which are simple and bullet-proof, or Honda for those with deeper pockets. Common complaints were leaking valve covers, loud vibration issues, and very cheap and nasty air filters that offer little protection, such as on the RH Series 6.5 hp. Oil leaks were extremely common, as we found many reports of oil running out suddenly on Courage engines โ€” which can lead to catastrophic engine failure โ€“ even if it has only had a very short operating life.
