So during our extended winter here in MN I had wild hair to come up with a project for myself.
To make planting my sweet corn patch easier and give me a reason to use my 2038r I thought I would build myself a 2 row planter.
It started as an John Deere 8 row 7000 planter a friend of mine had sitting out in the grove. He came to me wanting a 4 row planter to plant wet areas. So we made a deal that I would build his 4 row in exchange for the other 4 row units left over.
When I was build the 4 row I decided to leave the original transmission attached in the original position for him since he would probably need to be able to change the population more than I would.
So after I finished the 4 row I had to come up with a way to drive my 2 row planter. After some careful measuring to see what kind of row spacing would work best behind the 2038r I came up with 22 inch rows as to stay between the wheels of the tractor. My next issue was that there was limit space between the row units for a drive wheel. So I scrounged up some parts and came up with a hydraulic drive system for the planter.
The drive consists of a flow control valve and an orbit motor. Since the 2038r has a constant flow switch for the rear outlet I thought this would be the perfect setup for what I'm trying to accomplish.
I have got everything plumbed and turning nicely. Now I'm just waiting to get some seed so that I can start working out the calculations of how fast the planter must rotate to how fast the tractor will be moving.
I am open to any constructive criticism you may have.
