You know John, when I've got you and Mark questioning something I said... Well, let's just say I was about ready to book the day off work and figure out where I was going wrong! Even though I've had some experience in a shop, and took hydraulics and electrics as personal challenges, most of that was back in the 80's and I've had almost no opportunity to dig into that stuff since.

I have the same thoughts about the way DTAC presented this "solution". Tell us why so we don't go down a lot of deadends trying to figure out another way. It was obvious to me this particular bulletin was quickly written. I fixed three spelling mistakes before I posted the excerpt.

I think you've brought up the big concerns with heat and possible lubrication issues. I'd venture heat as being the primary concern. Maybe a cooler on the planter would help. It keeps going back to the issue that by the time you make everything work right, using a pto pump would be much easier and about as cheap.
