Was watching a couple of really big John Deere's pulling really wide moldboard plows through the corn fields , they did it with easy at a fairly good speed, the fields are big my guess over 1,000 acres, just curious do those plows heat up with all the friction from the dirt
, I know wierd thought but really thats a lot of friction and the plows looked like mirrors

In all my years of educating farmers, I've never heard of plows heating up. The soil that the plows are moving is relatively cool and being constantly replaced so heat from friction is not an issue.

Check your state's soil temperature charts.
Univ. Missouri has daily soil temperature charts at various depths, bare soil, 4 and 6 inches, for a number of locations around the state. Average soil temperature at the 6" depth in central Missouri was 61 degrees, on 1 May 13.

Never worked around big high speed rigs like that, but i doubt they heat up much more than our old 2 bottom behind the Farmall H did in our Mo. clay. After pulling it for an hour or 2 you could tell the point and molboard were a little warmer than the surrounding metal, but not by much. It would get a lot warmer just setting in the sun on a hot day. As Bill stated, the soil is cooler as you get a few inches down, and it would remove much of the heat created by friction.

Thanks fellas , just had to ask and knew there were some real farmers here on board with real life knowledge
