The large planters used today can take a lot of power per row because they are doing a lot more than opening a sparrow, shallow trench, dropping in a seed, and packing it back closed. The unit will do the tillage, and place herbicide, insecticide, and fertilizer in the proper position so as not to burn the seed but also get it close to the seed and not use up most of your money feeding weeds. My estimate is 5 to 10 HP per row but I have been away from that part of he business for ages. At Gleaner we estimated our 12 row corn head used 120 HP in good corn but I believe we designed for 20 HP per row. That was when our combine had only 270 HP so there was only 150 left for propulsion and threshing. In planting season you want to get the seed in the ground as quickly as possible so a 48 row planter will allow you to cover your 10,000 acres in a reasonable time. However if you break the frame on a 24 row planter and you are using 2 of them instead of 1 48, you still have 50% of your planting capability but with the 48 you are down. These are the tough choices.
