| Got every thing done, (except for the cab kit) on the 1976 7040 that I talked with every one about last April. Turned out great(better than expected). Will get pictures on here shortly. Have already taken it to a couple of local show's here in North Central Kansas & thinking about another one on Saturday! This show encourages implement's behind the tractor. Does any one out there know how many bottoms were recommended for average tillage? I happen to have a very nice 4-16, 3 point plow in nearly new shape , but don't want to disgrace the tractor by putting to small of a plow behind it. "BTW" the plow is set up for a 5th bottom to be bolted on, on the rear end & I am looking for the add-on bottom if anyone knows of one for sale! Thanks , Housemover P.S.S. Also have access to a A/C 12' Chisel (the one with long shanks that was made for Allis by Jeffery's). Would that be a close fit? |

| A 5-16 would be a good match. You may want to give some idea as to brand and model number to find an add on bottom. |

Original sales brochures show a 7030 with a 7 bottom. I wouldn't try pulling a 7 bottom for long with a 7040 but in our soil a 7030 or 7040 would be perfectly comfortable with a 5x18. ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |

| 5 x 18, or maybe 6x16. 4 x16's looks like a toy behind a 7045. |

| Moldboard plowing was almost obsolete when we sold 7040's. That being said, when a new plow was sold with a 7040, we went with a 5 x 18's semi mounted model. The tractor would pull it well and as deep as you wanted, which if one was still moldboard plowing, they wanted it DEEP. |

| At my Dad's dealership, when the 7030's first came out, they were paired with a 5-18" semi-mounted Monoframe plow. I can't remember for sure if it was a 2000 series or not, but I think so. |

| Thanks Guys, I myself had thought that a 5X16, or 5X18 would be the right counter part for the 7040. Never was one to load any piece of equipment over 75-80 % of capacity. North Central Kansas has it's share of clay & black gumbo! That being said I also know men who placed an 7X14 or 16 behind a D-21. Some folks just have a knack for pushing things to the limit. To answer the question on model of my plow , I'm not sure but I do know it's the one that was sold new with the late A/C 200 tractors just prior to the 70 Series being offered. And I know that it's not the mono-beam plow. It has a 4"-5" square tube mounted on top of the frame that looked similar to the older 3 & 4 bottom plows in the 60's & early 70's. It is semi-mounted, 3-point, with the plate on the rear end to remove the tail wheel & bolt on another bottom. Thanks Again, Housemover |

Housemover, Sounds like you are enjoying your 7040 - Congrats! Is it a Power shift 12 speed or Power direct 20 speed trans? Does it have the power shift rear wheels or non-power adjustable rear wheels? The power shift wheels make for quick work of moving the right rear wheel into plow furrow if its a semi-mounted plow. Or maybe if you're just setting it up for shows with plow, then it may not matter?
Here's a pic from an October 1974 AC brochure.  |

| I pull 5x18 ih 710 plow with my 7040s. No probably at all 8-10 inches deep in my soil. Could probably pull 6x18s but that would be harder on the tractor. I think 5x18 is a great match for the tractor. |
