she sounds awesome.  Going about 3' deep with 2 shanks.  Haven't tried it with 3 yet, but this is all she wants in this field.  Never been ripped this deep before to my knowledge.

I have been away from the forum for awhile. Wanted to get back on some of the tractor projects, so this is as good of a first post back as anything I suppose. My poor oil clutch got water in it while sitting outside unfortunately, so I drained the milkshake and did a number of flush cycles after that. Got most of the crud out but some rust flakes come out still unfortunately, will have to keep working on that. Might need to soak in Evaporust and remove the top inspection cover and pressure wash it all out even then start over.

Nice tractor.

Welcome back. That is a tidy D7 and Murray ripper. I will be doing similar work after a tenant farmer is done harvesting an old block of Chandler walnuts;following a D-10 after it has been deep ripped twice and the roots picked up. I think the 17A is one of the most agile machines for pulling a Marvin triplane scraper.
Where was that photo taken? We are in Yuba City.
Thanks for posting. JM
