| Looking at getting a bigger tractor to relieve my 7020 from heavy tillage and have found a 7030 in decent shape priced right. What size tillage equipment a 7030 could run and hold up. I would be looking to dual it up and wight it down as well. Currently running a 5x18 plow. 20 foot disk and 18 foot digger. |

Um….probably not much bigger? Pull what you have a little faster and be easier on your tractor. I have a 7045, pull 6 plows and it is ALL it wants. 20 foot disc for me too. Could probably be a couple feet bigger. Digger is a very generic term, type of shovels, weight of unit, depth used….I pull a 23 foot JD 1000 field cultivator and like to pull an Unverferth rolling harrow behind it. It will power hop or power out up hills depending on soil. You’re going up one size, not a revolutionary change. JMO, your results will vary. |

| Chassis the virtually the same. HP is 10 more if both are set stock. |

| Your relly not gaining much and will stress the 7030- 7050 or a 7060 turned up a little will do what your thinking |

| My 7020 is pretty healthy and runs everything I have however I have a opportunity to take on another 200 acers that are quite aways from the house and would like to keep one tractor there. How hard is it to run 150 horse out of the 7030's 426? And would a 7030 hold together set at 150 horse? It would be used for chisel plowing,digging, planting, rolling,seeding,fertilizing,and pulling gravity boxes. The reason I ask about a 7030 as I know where a real decent one is for about 1/2 to 1/3 of a decent 7060 or 7080. |

| 7030’s AC 3500 426 would be a solid old girl. It would be fine using the 7020’s implements. But it has no intercooler. Neither the 7030 or 7040 (lower hp 426s) have intercoolers. So turning up fuel on 7030 could easily cook it’s engine. Especially how you’ve described weighing it down & increasing its loads. IMO, Try finding an AC 3700 (7060) or 3750 (7080). |

| I would never advise "turning up" a 7030. They don't have piston cooling on them and I've seen more scored pistons over the years than I care to think about. Running a straight pipe is good, as it can drop exhaust temps 100 to 150 degrees under full load. Keep the cooling system clean and always keep water temps under 210 (straight up on the gauge). You do whatever you want. I'm sure there will be someone who will claim to have a 7030 running 200 HP and never had any issues. |

Just looked up Both, 7030 is the Older of the two(73-74) and 1hp LESS than a 7020(78-81), actually NO difference. https://www.tractordata.com/farm-tractors/tractor-brands/allischalmers/allischalmers-tractors.html" rel="nofollow - TractorData.com - Allis Chalmers farm tractors sorted by model

| Another option would be to keep my 190xt up there for the season and keep running the same size implements I would have to find a smaller chisel plow the disc and cultivator I have used on the XT no problems before. |

| 7020 was 122-124 HP and 7030 was 130-132 HP both at the PTO. Pretty typical of Tractor Data to be wrong, like almost every one of their HP ratings are incorrect !!! |

| Turning them up, loading them down, running them hard is probably going to find any weak link these older tractors might have. Like Dr says - keep it cool - too much heat will put them out of commission. The bigger displacement engine in the 7030 might surprise you. Sounds like you have one found at great price, I'd go for it, see how it performs before weighting or tuning. |

Did the 7040 or 7045 have piston cooling? ------------- Gleaner: the properly engineered and built combine. If you need parts for your Gleaner, we are parting out A's through L2's, so we may be able to help. |

I think the 2 pinion differential would scare me some. 7045, 50, 60, 80 have the 4 pinion and I'd want that for my "big horse" I wouldnt turn up a 7030 myself, and the Dr.'s advice would definitely seal the deal. I had no idea the 7030 didnt have cooled pistons. ------------- Gleaner: the properly engineered and built combine.

| 7040 and up always had piston cooling. 7030, D-21,210/220 did not. A 7030 engine already makes 12 to 15 more flywheel HP than a 220 to get 130 HP at the PTO due to the mega-hydraulics and 20-speed wet-clutch transmission. |
