hi guys just wondering your opinion on how many bottom plow can the 7020 handle with stock horse power? Our land in this area varies a lot from heavy old clay to sand and i plan on using it on the farm i work at, and it has all the soil types. The fella i bought it from pulled 4-18" allis plow. i was thinking a 5 bottom adjustable width would suit it fine, would be able to adjust it according to the ground type and traction! i don't wanna work the crap out of it either! any advice is appreciated!! ------------- 1-B's, 2-C, 2-CA's,2-WF, 1-WC,1-G, 3-WD's, 2-WD45, 1-RC, 1-D17 Diesel, 1-D14, 2-D15,1-D17 row crop,1-D19 gas and All Crop 40,60,66,72,90 and 100 |

| Full fluid in the rear tires is a must, as are full front weights for the Traction Booster to work well. Any 5 or probably 6 bottoms would work. Less bottoms you can go deeper or faster. |

| Grandpa used top pull 6-16's with a 90HP 4020, but it pulled the guts out of it. You've got another 20-30HP over that that so I think you'd be fine with a 6-16 plow. If you're not plowing tons where you're concerned about geting done fast you'd be very safe with 5-16's |

| In similar soil my 7020 had met its match with 5-16s. Better to match it with a plow that utilizes its horsepower while not overloading the drive train. At the end of the day, if you pull a larger plow slower vs. pulling the right plow at a sustainable speed the amount of ground you roll over each day will be the same anyway. To me 5-16s is the proper balance. |

I pulled a 4x18 AC 2000 monoframe plow with my gas 4020. In sticky ground I had troubles keeping the front wheels on the ground. Needed a ton of front weights I guess. I added all the weights I had, just front wheel weights, took off the front bottom, and readjusted the hitch to compensate for losing that front bottom, and lowered the hitch also. Changed from plowing at 3.5 mph in 3rd gear to plowing at 5.5 mph in 5th gear which didn't have enough torque to climb the ring gear and pulling 3/4 the plow at 11/7 the speed I got more land plowed per hour and the plowing results were smoother at the higher speed with nearly all the plow furrows leveled by the faster plowing except in extremely wet patches. I still have the plow and the tractor but haven't plowed in a long time. Gerald J. |

We pulled 4-16s with ours in heavy clay,, we could pull it 6 mph easy most of time. We had a 7030 that we pulled 5-16s with. The 7020 struggled with the 5 bottom the 7030 toyed with it. |

If possible, go back to the 7020 seller & buy his AC 4-18 plow. Doing the math, 4 x 18" = 72" width is only 8" difference from a 5x16"=80". If his AC 4-18" is a 2000 series mono frame, it is a nice plow. |

| pulled 5-16's with my 7010 for years. both hill and bottom ground. used low side, 3rd and used the floor buttons. no fluid in rear radials, and 400 lbs weight on front. did not pull hard. you should be fine with 5 or 6 bottoms. |

| When 7020's were new, our dealer rented out a 7020PS with a 5-18 Melroe #912 spring reset plow. We have heavy clay soil, but the tractor pulled it ok, when the tractor lugged down we just went down a gear. We bought the plow as a demo unit and hooked it behind our AC 220. One year my brother hit a frozen spot on a side hill and broke off all the bolts that held the front hitch to the plow beam. Put in new bolts and new hyd hoses and went back to work. |

around my area, you can buy all the plows you want for iron price, buy 3-4 of them and pick the one that works best. get all the same brand and switch parts around before selling them back to iron buyer. the oliver/white plows were the hot nuts here, when we plowed like 30+ yrs ago. my land hasn't been touched for 25yrs an yields better every year. got to planting rye in the fall as a covercrop; that took it up another notch! ------------- AC from the start of my families farming career till the end! |

I think yields have been going up regardless of the tillage or non tillage but in my area there is a definite boost to yields in plowed ground vs no till ground.Tillage effects on yields
http://www.extension.umn.edu/agriculture/tillage/on-farm-comparison-of-conservation-tillage-systems-for-corn-following-soybeans/img/fig3-yields.JPG" rel="nofollow">
Figure 3. Corn grain yields for each tillage treatment in 2004 and In 2004: The unusually cool growing season of 2004 undoubtedly had an effect
on the performance of the three reduced tillage systems in this study.
Other research has shown (Randall and Vetsch, 2005) that reduced tillage
systems can have significantly lower yields compared with conventional
tillage in unusually cool or wet growing seasons, especially when
long-term no-till or reduced tillage systems are used. In the six sites
in 2004 where chisel-plow-plus increased corn yields compared with
strip-till, four of the six sites had a long-term no-till or reduced
tillage history. http://www.extension.umn.edu/agriculture/tillage/on-farm-comparison-of-conservation-tillage-systems-for-corn-following-soybeans/" rel="nofollow - http://www.extension.umn.edu/agriculture/tillage/on-farm-comparison-of-conservation-tillage-systems-for-corn-following-soybeans/ ------------- -- --- .... .- -- -- .- -.. / .-- .- ... / .- / -- ..- .-. -.. . .-. .. -. --. / -.-. .... .. .-.. -.. / .-. .- .--. .. ... - Wink I am a Russian Bot |
