This problem has been around since the days of steam engines.....But in the 30's & 40's it got worse. It got BAD in the 50's, the HP race years. High compression heads, biggers sleeves & pistons, stroker cranks....Make an M into a 70-80 HP tractor instead of a 36 hp....then Hook a 4-bottom plow & 12+ft disc behind it....instead of the 3-bottom & 9 ft disc. Then add a couple thousands pounds of weight because a 5000-6000# tractor can't pull 4 bottoms. And complain because the transmission & rearend can't handle it! ANY tractor that constantly pulls in LOW gears is over-loading the final drives, I don't care what color, model, etc. I saw a chart from AGMA, American Gear Manfacturer's Assoc. that shows as load or power thru a gear train is doubled the life expectancy is reduced to ONE Tenth. So with today's equip. I would say if Your tractor can't pull Your normal loads at least 4-5 mph it's over-loaded, the amount of ballast goes WAY up, slippage gets REAL bad...fuel efficiency dies....Speed doesn't spall bearings, stress crack gears, twist shafts.
