New last spring before planting. I did everything on the hex shaft. I found a set of new take off row clutches for <$100 each so did them too. I even replaced the double sprocket, idlers etc going to the row unit. Both hydraulic drive motors were also replaced with new take offs. New 36 cell discs and meter covers. I've done it all and some of it twice. Can't get there. I've heard there is a bit of a known issue in the hydraulic block that feeds the fan and the 2 hyd section drive motors. The explanation I got was that it somewhat shares oil and when you hear the fan surging (which I do) it is also affecting the drive motors. The planter is excellent other than spacing.
I think you are on to something with the fan surging, if it has two fans with one being on scv and other on pto pump whichever one is surging is low on flow.. if only one bulk fill and one vacumn with no pto pump still could be the low flow.
OR restriction in return hose.
i ran a Magnum rental one year on a 1770 and i could see a wavy pattern in corn tassels. blamed it on low flow, never noticed it at the time of planting, but that was many years ago.
just some ideas to maybe help
good luck |
any electric row drives that can be run with a Pro 700?
