This is a continuation of discussion about the cylinder on the plow in the 300a pics: I did go out and plow for the first time with my VAC and converted ford 101 1bottom plow. I also have a CA allis with snap couple plow. I believe the ford worked a little better as it rolled the sod a little more, but the plow was almost scoured by the time I was done. The allis was not. Tractor ran flawlessly. I had hoped to plow 6" deep in ground that was hard clay with 30 years of fescue sod on top. It would go that deep but wouldn't stay there. There were also small tree roots That may have caused it to go shallow. Last year when I made my first pass with my Allis plow I cut the TIme Warner cable. I personally dug the trench for the new cable with a ditching spade. I am sure I had that cable laid 8-10". But Sure enough I hit it again plowing. SO the plow must have gone deep some of the time. THe only thing I can figure is frost heave must have pushed it up. That is why I didn't send pics yesterday--no internet. Don't laugh at my lame guage wheel. It's main purpose is to hold the plow up when it is unhitched. 1 bottoms like to fall over. I did use it as a guage wheel of sorts. I had it set for 7 inches so I could see how deep I was plowing. Never saw it hit the ground but I wasn't looking when I hit the cable. It would be nice to find one of those Case guide wheels if I ever am able to plow deep enough to need it.
