Recently purchased a used 1770nt with the hyd drive, had a 1770 with mechanical trans before.  Not too impresed with the pile of seed when you stop to either go over a terrace riser or just to check something.   Also, seems to take too long for the seed to start dropping when I restart.   I am running the precision drives with an Insight.  Might be looking for a mechanical drive to put on this thing unless I can change this thing to work better.

Btw, on flat  running it does great, just doesn't work as well on the hills and terraces as well as I would like.
