The double tractors reminded me of when one of our neighbors combined the front half of something big, Ford, and 4 wheel drive with something big, Ford, and 2 wheel drive. It did about 25-30mph when the speed limit for a tractor in the UK was 20mph- dunno what it is now. The steering had about a foot of slop in the middle and hair-trigger everything else in the 2 inches of movement either side. Guess who was stupid enough to volunteer to drive it when it was borrowed? The brakes were also hair-trigger.
C’mon guys. You’re working flat ground. Piece of cake! Let’s get on the side-hill and do some old alfalfa sod. Every other year you have to turn it up hill so you don’t end up with helluva dead furrow in the years to come….course you could plow always down-hill and have a flat farm in a 100 years or so….wishful thinkin’. But tuning up hill with 4-14s wasn’t fun as the 14″ furrow wanted to roll back down…3-16s worked better. That’s how we did it in LaCrosse county WI.
