my ol man tells me that while on a trip to moline in the late 60s or early 70s to watch his combine being built he got invited to deeres experimental farm to watch chevy make a commercial pulling a 4 bottom plow over like 40 acres to prove how tuff they were and he claims he saw it on tv later that year has my ol man drank to many nattys? did any of u guys see this i am way to young to remember anything close

I remember it well, it was sometime after the 1973 body style came out. Chevy commercial had a blue and white K20 with a 400SB and a manual 4 speed pulling the plow. The commercial never showed them starting off with the plow in the ground, they alway got a running start. It was a 4 bottom trail type plow, probably 4-14's... That commercial did sell at least one truck... Late 1977 I bought a 1978 K20 Scottsdale, 350SB, turbo 400, limited slip... Truck still lives today except it has a .30 over, 396/350hp under the hood.

I remember seeing it as well... I had a 75 with the 400 in it but didn't try to do any plowing with it
