What?????

It takes the same time to turn around a planter.  if you make two passes with a 48 row for end rows and you make 3 passes with a 16 row for end rows the 16 row just cost you 1/3 more time than the 48 row would have.  plus you have how many less passes and less turn arounds with the 48 row as a 16 row.  two pass headlands are two pass headlands, take the same amount of time if you have 1 row or 48 rows behind you, it is still 2 trips along the headlands!  Now take your one row, how many passes would it take too turn you one row around?  I think atleast 12 passes, so you just wasted 2 hours planting endrows while the 48 row had both ends done in a half hour.

Why does it take longer to load seed for 160 acres in a 48 row than it does a 16 row?  takes 64 bags either way.  why does your time double for bigger planters?  the smaller planter would take more time as you have to stop more times to fill up.  Course I think the CCS hoppers are the same size on all the planters.  so if you load up a 24 row CCS or a 48 row CCS it is the SAME load time to do 160 acres.  

Greaseing??  24 row you grease every 20 acres per row.  480 acres per greaseing.  48 row at 20 acres per row. 960 acres per greaseing.  you would need to grease the 24 row twice and the 48 row once so you grease 48 rows either way.  

your one minute greaseing on the one row is funny!  takes one minute per row but you grease 48 more times than the 48 row planter does so it takes the same time anyway!
