Thinking of installing mirrors and lights on a 1972 4020D with factory cab. At the John Deere web site, they have LH (part no. RE151161) and RH (part no. RE151162) extendable mirrors, but they don't indicate if these mirrors will work on 4020 model. Also, I was thinking of putting on the flood lamp kit (RE32441), along with the relay kit (AR91166). All of the factory-installed lights on the 4020 work, but I wanted to add a little more light for hauling corn (in the field and on the road). If anyone has installed any of these JD lights and/or mirrors (or can recommend another manufacturer), I'd appreciate the advice. If you know of any difficulties associated with installing these or other lights and mirrors, your comments would be appreciated as well. Thanks, and would just like to say the 4020 is quite a workhorse. We bought it used (with about 1700 hours) in 1979, and since then we've put another 7300+ hours on the tractor. Still in excellent shape and running strong.
