| Dear All,
I am farming in Hungary in Europe and this spring I found a late model 750 boxdrill 7,5" (025953). It had some missing parts, wore out blades, tight bearings etc. I have read this forum many times and helped me a lot to get an idea how to rebuild the drill. We have worked on it and it is in a good shape by now. This machine is not very popular over here - just a few unit was exported from the US in 1998, so it hard to ask anyone about experience.
I have problem with the coulter pressure. The previous owner changed the pressure gauge so it doesn't have the colored stickers so I don'T know what is the recommended pressure range. Anyone can share a picture about the original gauge?
The other problem is that if I set the pressure to a 1000 psi after a 100 feet it dropes back to 500. I have checked the Hydraulic couplers and lines about leakage, but I found nothing. I have no idea what should I check.
This drill is equipped with the original JD marker. Is anyone knows how should it work?
Right know I don't like it. Once I activate the hydraulic, both marker arm goes down and once the reached the ground I am able to lift up one of them. I can't make rhythm with it, if I want to change it on the headland the marker arm which is used comes up and I am not able to take down the opposite one. It's a pain in the *ss to turn with it,
Is it normal, or something messed up in my system??
Thanks in Advance
