Running a 36-20 Kinze 3700 here.

Cheap.  Big.  Single bar.  Enough room to work on row units on a single bar unlike 15” planters on a single bar.  Not as heavy as a 47-15 planters if you want to standardize around 60’.

Row cleaners.

Sprayer on RTK drives right down between the rows and you don’t know it was there, even at fungicide time.  Could sometimes pull that off with 15” beans for 100’ or so.  I have to double check the U-bolt spaces in the frame and see if I can make 22” or wider tramlines on 120” centers.

More push than 15’s if the ground crusts over at planting.

Looks like the future for corn even though I am still planting 30” corn.  Either plant in wide track and post with drones on do 120” tramlines and see how that works for sidedressing and/or spraying.
