I cut my teeth on a 8640 and  24 row kinze  planter in  1980.    Boss  said;   'figure it out'. 
 it  wasn't too bad for me, as I didn't have any other pre conceived planting experience to  hamper my learning curve.    

Fast forward  40 yrs...  and after  farming my own stuff  with 8 row hitched to 2wd  tractors   my planter tractor broke down, so I put my ol'  MF 4880  articulated on it to finish up the last field.   Looked silly as all get out!   But  within   100 yards of starting,   all the  nuances that I learned  back as a kid  came flooding back.   Being able to see 2x's  further down the marker row,  and  using  a little different  wrist action on the steering wheel  got me straighter rows than I ever got  with the 2wd.  Holding side hills  better didn't hurt.     If I had to,   I could turn around cleanly on only 8 rows..  no gouging or rutting   the headlands.      
Certainly not the most economical way to pull a  8 row.. but   it sure brought back sweet memories.
