I spent a LOT of time on side console tractors. The BTO I worked for traded a pair of '64 4020-D's off on a 4320 with factory ROPS cab with A/C, and a nfe open station 4020-D. The 4320 only had three hours on it when I took it out plowing the first night. Got to his place about 4 pm after school, called it a night about Midnight. I put more hours on the 4020 actually. I liked the cab in early spring and late fall, and chopping haylage which is why he got the A/C and upgraded from a 4020 to a 4320, but the compressor already failed by the first cutting of hay. So instead of getting dust & chaff all over inside the opened up cab I had him put the 4020 on the chopper.
But YES, they do exist. The neighbor Dad traded help with and farmed 80 acres of rented ground with got the first side console 4020. One Saturday morning Dad tells me Neighbor wants me to chop stalks off the endrows he's picked. I go over to his place and he has this shiney new side console 4020-D hooked to the Brillion 6 ft bushhog. It had something like 5 hours on it. When I pulled Dad's 6 ft Brillion I used my Super H. Dad bought the cheapest weakest soft bolts for shear bolts, the Super H would snap them if I hit something like a clump of dirt.
