2bottom dearborn on a JD 70??

I do my farming with a chisel plow and disc. Had a guy ask me if I'd reseed his alfalfa stand for him. It has gotten to where there is almost no alfalfa left in it (I explained to him about not putting alfalfa right in after alfalfa but he says this is the way he's always done it so.....)
Anyway I don't think I'll do a good job with my chisel, just leave too much alfalfa there to come back (probably doesn't matter since he wants the alfafa). I don't have a mold board. He has a little, worn out 2 bottom dearborn. I could pull this easily with my JD 70 but wasn't sure what quality I would get out of it. Plow is considerably narrower than between the tires on the 70. When done field needs to be very level since it is flood irrigated.
Only 5 acres
 

Gonna be really slow, with only 2x14" (maybe 2x12").

Not at all sure you could ever rig that plow to work with your JD 70.

Anyone around you have a decent larger plow.?
It can handle 3x14", 3x16" or 4x14" with no problems. (Mounted or Semi-Mounted).

I'm the odd nut trying to get started. I have a few guys I could ask that have 4 or 5 bottom rollover plows (too big for the 70). The field as I said is only 5 acres and has a 12 foot gate. The guys with the real equipment just can't get in and its not worth their time.
Maybe I'm worrying about nothing and should just use the chisel plow. With 12 inch sweeps it does a pretty good/clean job and I suppose it will not hurt anything if some of the alfalfa survives.
 
Use the chisel.Go over about 3 times in alternateing directions.If you can,try to go a bit deeper each time.IIRC,you're in flood irrigated country.You should try to bury the 'trash' for better water flow.I'm sure someone close will plow it for you.Just ask.It may cost a couple hundred....Then you can do the rest.As was said the 70(it has MORE than enough ponies), lacking draft/depth control will be tough(a challenge) to use on a mounted plow.But you can use a chain to hold the plow to a constant depth.I've had to do that sort of thing when I've pulled a 3 bottom rollover with my Super M.Worked great!Plowed level and even while supported.
 
Like DeltaRed says- multiple passes. It"s a given that a chisel plow will not properly work sod in just one pass. Each pass at a slight (not 90) angle from the previous. Sweeps or twisted shovels will do more than spikes, and take more power.
 
You could never get that Dearborn to work on your tractor as they were made for a 52" tire wheel track and your 70 if it will narrow down to what an A would will be 56" and then you would be close to rollover spacing. Tractors of that height we never set the tread width to less than 66", that is center to center of rear tire. Always had drag type plows on them tho. And sweeps on a chisel plow, that would not work around me, you could only pull perhaps 3 sweeps here if you could even get them in the ground. I say get the 4" twisted shovel for your chisel and here with your power you could only pull 5 shovels. And then only 5" deep in the alfalfa.
 

That has always been the problem with the Models prior to the "20 Series", they needed a Depth Wheel (gauge Wheel) to control plowing depth.

A decent "Pull-Type" plow would work fine too. Only thing about using one is getting used to larger End-Lands because of the added length..and backing it when plowing off the ends..

I assume you will not need to have a Dead Furrow, with only 5 acres, just turn it all toward the middle, to keep the field level..

I'd sure like to see a 70 pull 4-14's in alfalfa with "no problems." The whole thing sounds like a potential train wreck to me.
 
I think that's what I'll do. Time is always an issue for me. The Chisel/806 will do the field in about 1 1/2 hours, will not hurt or use much more fuel to do the field twice. It will get disced once to bury trash and smooth it up before planting, last pass I pull an old spike tooth harrow behind the disc.
Thanks for the advice.
 

Don't discount those old Diesels, they have a huge amount of grunt.
The only way I can tell if my 720 is getting a good load is when it starts showing just a little smoke, yet it still has not lost any RPM.

I'd chisel it about 6 times probly and then disk a couple times to ever get it worked near good enough for alfalfa seed . If you do mold board it your still goina work the crap out of it to get it good enough for alfalfa seed.
