We used to pull our 16 row with a 2255 and had a full 175hp on the dyno when last checked, really worked it hard, of course we had no till fertilizer coulters and frame mount no till coulters on our planter. Replaced the 2255 with a 4-175 turned up to 210hp and it barely knows it back there. Used to easily pull our old 8 row with a 1855 and standard dry fertilizer coulters.  Big question would be what kind of starter fertilizer do you plan to use if any and how mellow is your ground? Am 36 years old and can never remember having any other planters other than the whites and I would really think that a 1655 would be really lacking in the horsey department.
