210 ac plow size

Anyone have opinion on number of bottoms and size moldboards be good fit for a 210 ?

Lot of variables. Stock hp or turned up? Soil type for sure. My 220 (170hp) pulled neighbors 720 IH 6-16 on land plow well in 5th but clay spots gave it all it wanted. 4th would make it easier.

Also while I'm asking bout power for implements, planning to buy new holland 2 row chopper (always been around new Hollands and had good luck) wondering wat number chopper would fit this tractor well.

Allis-Chalmers rated the D-21 S2 at 7 bottoms and 18 inch bottoms didn't exist at that time. The 220 was rated at 8 bottoms.  So, you decide. The 210 was only 5 less HP than a D-21 S2.  I have literature for the 210 and AC never gave it a plow bottom rating.  The 220 @ 135 HP  with 8 bottoms is 16.9 HP per bottom.  16.9 HP per bottom x 7 bottoms is  118 HP and a 210 was 122 HP.  Your results may vary.

Back in those days, they always over sold plow size in my opinion. They weighted them down and cranked up the fuel just so they could pull them. I always like pulling smaller implements faster, it's so much easier on parts. I just cringe when I think of pulling the guts out of a tractor all day long lol! To me a great match for a stock or even tuned up D21/210/220 is a 5 bottom, either 16 or 18".  I've got vids from pulling my IH 540 or 550 5X16 plow with my 210 when it was making about 400hp. That was a lot of fun! Again, just my opinion, it's worth just what you paid for it lmfao!

It would be fun to see those videos, Ed...

I'd buy my 2000 Series, 6 x 16 plow that I sent you a PM about this morning, hook it up to your 210, take some photos to share with all of us here on the Forum, back it in the barn and then go no-till.  

Thank you very much everyone for replies. Appreciate it! Lol like the no till comment. I can count on one hand number of guys in my county still moldboarding. It's lost thing. I'm just hobbying on dad's old farm on the side and wanna have some fun working the old tractor and just do things old school to get my neighbors talkin. Plus if it's a hobby I'm just throwin money away so why not have fun doin it and turn some dirt and blow some smoke lol

XT-8000#'s (on the heavy side) and 80 drawbar HP; 210-12,500#'s(on the light side) and105 draw bar HP

Moldboard plowing is/was generally a pretty slow speed operation. A-C plow bottoms weren't "high-speed" bottoms and did their best under 4.5 MPH actual speed. If you think about a mighty One-Ninety XT or 200 in high second (4th speed) that was just 5 MPH @ full throttle no load. Add at least 10% wheel slippage (or more in most cases) and an engine getting pulled down some, and your actual speed was closer to 4 MPH max. Trying to pull those plows faster than that exponentially takes MORE HP !! because of the curvature of the moldboards.  I love those who brag about plowing with a WD45 in 3rd gear !! The only way that could ever happen where I grew up was with 14 inch bottoms, no more than 5 inches deep in soybean stubble, not alfalfa sod !!  Those who claim to do that would be embarrassed to come to our farm and see how third gear (with a STOCK WD45 mind you) isn't even a possibility. Same goes for the bigger diesel tractors.

D-21's, 210's and 220's are "big frame" tractors and are over 100 PTO and drawbar HP and were category #3  three-point hitches.   A 190XT came from the D-19, which is a much smaller and lighter tractor chassis with a category #2 three-point hitch.

Dr is right we have those kind of soils around we had to have the fronts filled with fluid and extra weights. Good plow shares to even get the plow in the ground sometimes. This is on sod ground or ground that was packed chopping corn silage. Alot of those problems were worst years ago when ground was tilled and we destroyed organic matter. Now we notill or  minimum till.  So if you have tough soils why pull the guts out of a 50 year old tractor unless you are just plowing a few acres for fun and want to see what it will do. Around here a 4 16 or 18 is a good fit behind a 190 or 200. I agree there is ground where you can add  2 bottoms to my recommendations all you need is traction.

We always pulled 6 x 16's on-land 3000 series AC plow with 7030/7050 and no front wheel drive. Could have easily pulled 7 bottoms but we didn't plow all that many acres at that time in history.

Our 220 played with a 6 bottom 9000 plow. I have forgotten how to make a video open here but here is a YouTube link of it throttled back in 5th following the D19
220 plowing

Pulling a 6 X 16 9000 series on land with series II D-21, 4th gear, 8" deep. Hard clay and black jackwax soil. Will carry front end in compacted soil - 2 donut weights and 24.5's half full of fluid and front donut weights from "F" combine.
