You have 100 acres per foot of planter.  

This year we are going from 30 to 15 acres per foot of planter.  

Way I see it, 42560 sq ft per acre is 8.25 miles long at 1 foot wide, if you average 4.125mph on your fields inclusive of end rows and point rows that is 2 hours operating per ac per foot of toolbar or 200 operating hours per your planting season.

Depending in how your fields are laid out and how frequently you need to stop, refill, fold, move, and repair, maybe 67% overall efficiency moving in the field vs staging?  or adding 50% of hours?  So 3 hours per ft of toolbar or 300 hours overall.  Anywhere close?  

Clutches, monitors, autosteer, tending equipment all make seem to increase the efficiency percentage and make some longer hours easier.

Big differences in weather windows, equipment cost/age, how many operations you are performing in one pass and how long the pit stops to refill take, and also and how nice you want your working conditions to be in the cab.  That’s what makes a market.

Nice equipment.
