Moldboard plowing

[Farmer495]

And some moldboard bottoms are referred to as high speed bottoms & require speeds around 4-6 mph to roll soil correctly. I wonder how deep the OP's GP was plowing?

I agree, my IH plow likes 4 MPH or so, I can pull it faster but fixed beam and rocks don't agree. 2MPH and the sod hardly wants to flip, 6 MPH it almost spins it over an extra 90 degrees.

Yes they are shiny. Umm I think it pulls straight? I'm not sure. Also when the first moldboard gets into the ground it likes to spin the rear wheels. There is 2 Colters one is missing in the rear. No I don't have any photos sadly. That's what I thought maybe a higher gear will work. We r done plowing anyways

If it's spinning wheels 2nd gear at an idle then it might be too wet (slippage) Extra speed helps in wet going. I will speed up in a wet location, in my case with gear drive tractor I'll just open the throttle up to gain speed. ( stay in same gear under load) No way would I slow down, you want momentum.

Ok that makes sense

Does the tractor turn the sky dark with its black smoke?

What wears an engine more: “lugging” (but not close to stall & can increase rpms if desired) or higher rpms? I’d guess more rpms has greater wear (even though under less torque)?
What gets better diesel burn: Lugging or higher rpm? I’d guess high rpms do, less fuel per rev gets burnt better than trying to burn more fuel per rev? As evidenced by less black smoke.
Personally, I like hearing low rpm diesels and Harley’s applying torque better than screaming weed-wackers.

bonus question: Does a lugging engine or high rpm engine run cooler. Issues to consider: Friction of parts moving vs friction under torque vs amount of fuel/cycle vs amount of air/cycle vs efficiently of cooling system at various rpms, etc..?
Hmmm......

I consider that the maximum power is designed to be achieved at PTO speed or thereabouts, plus the fact that you will have the most oil being pumped through the "veins" so that is where the engine is "happy"
