Several years ago(late 70s/early 80s) the local young Farmers club farmed an 80 acre silage corn fund raiseing project.It was plow day.There were many tractors present.My friend had a nice 4320 and a new IH 140(4x18)rollover plow.(his family had 5 4320s) everyone else had 30/40 series Deere,86 series IH.....(newer/bigger tractors).They stuck him in the back of the line because it just an 'old 4320'.He kept having to downshift,throttle back...so......at the end of one pass he just spun it around ,throwed it into 5th dropped the plow, pulled it open and took off. The race was on!No one could catch him,everyone tried.Richard's 'old' 43 beat em all. Seems the harder it pulled,the next gear up and so on.. it just blew blacker smoke and WENT. I think there were a few POed guys there that day,others got a new respect for an 'old' tractor.I love it!!.
