Hi Tom.
I was going to buy a second 4200 but the Case-IH 145 caught my eye with auto-resets and more clearance. Some say they pull easier and cover better. I don't have enough experience with it yet to speak to that. The 4200 has 60" from right bottom share to left bottom share, the 145 has 72". The 145 bottom is also not under the main beam as is the 4200. So it ought to do better in stalks and tall grass.
The JD 4200 does a complete roll-over with just moving the SCV lever once. The one disappointment so far is after I purchased the 145 I found out you had to operate the SCV twice to get it to roll-over completely and then you run the risk of it locking (wrong word but best I can think of right now) in the "half rolled over position". Anyway the 145 would not maintain its full rolled-over position. I rebuilt the tractor SCV's, re-built the Dual pilot operated Check Valve, and went to rebuild the cylinder when I seriously broke the cylinder just due to ignorance on my part.
SV suggests throw away the Dual pilot operated Check Valve. Other sources suggests he is right. Well, I plan to try that as soon as I have the 145 back on the 4250. It turns out the cylinder, except for one connection, is a standard 8" stroke, 20.25" retracted length, with 3" bore, and 1.5" rod diameter. I have cylinders that meet that but with smaller rods and pipe thread connections on both ends. I will try one of them.
I also plan to try it again with the Dual pilot operated Check Valve but I have to decide if I want to fix the original cylinder. While standard in everyway it has an O-ring connection on one end and pipe thread on the other to accommodate their incorporation of the Dual pilot operated Check Valve.
Well, a lot of people use a 4020 on these plows, including SV. It looks like he is operating on level ground. These plows are heavy with six bottoms hanging back there. I have 10 weights on the front of my 4250 and need it all. I tried eight last year. When I used my 4320 I had a dual starter weight bracket with eight slab weights. The 4250 handles these plows better but I often operate on some pretty good hills. Both my plows are 3x18".

Today's Featured Article - A Cautionary Tale - by Ian Minshull. In the early 1950s my father bought an Allis Chalmers B and I used it for all the row crop work with the mangolds and potatoes, rolling and the haymaking on our farm. The farm and the Allis were sold and I have spent a lifetime working on farms throughout the country. I promised myself that one day I would own an Allis. That time event
