| A "stock" 200 tractor was 94 PTO HP. There never used to be a problem turning out the torque screw several turns (or removing it and replacing with a plug) and getting 115 PTO HP. Takes 5 minutes to do. This assumes your pump and injectors are in good condition. More HP comes from more fuel. A better turbo won't change things much if any. Same for injectors unless yours currently have plugged holes. Increasing the high idle really helps on forage equipment performance. |

| So is the torque screw on the outside of the pump? I read on another forum that you have to take the top off the pump to get to it. |

| The torque screw is external and located just above where the lines attach to the hydraulic head. It sticks up/out at a 45 degree angle and has a plastic cap on it that unthreads. A 7/16" wrench and an allen wrench to adjust it OUT. Just remove the whole thing and adjust it 3 or 4 turns and replace. Swinging room isn't much on the pump. Removal of the pumps lid and governor guts is for roller-to-roller dimension and if your torque screw change isn't enough, that's where you go next. Remember your cooling system and tight fan belts. A couple hundred more RPM really helps on a chopper !!! |

Are you trying to pull a 2 row chopper with a 200 if you are you’re going to need around 150 horse on the pto A 200 will handle a 1 row very good but if you double the material going thru the machine it’s gonna be very slow We went from a 1 row to 2 row on a 7010 and it was a load on it A 7045 or 8030 will handle a 2 row really good |

| What kind of chopper? I filled many many 20x70 with a 190XT3 chopping 2 rows with an 800 Gehl, and the neighbor had a 200 and a 600 Gehl and it was no challenge for either one of them, and hay was in 12ft swats. My uncle bought a 1070 to upgrade the xt in 79 and the 1070 couldn't hang with the XT especially in mud |

| It all depends on your population and corn height. Chopping corn in 1985 at 10,000 population is a lot different than chopping corn at 40,000 population. I've seen two row of corn taller than the tractor cab and 150hp could barely do. Go on the other side of the field out of the much chopping 6' tall corn and you had no problem and picked up a couple gears. |

140,000??? 80,0000? High yielding corn for grain is about 35,000. I would hate to pay your seed bill

| I think back in the early 2000,s my Uncle used my 200 with a Jd 38 2 row chopper- doing corn and millet mix- run in 3 rd- but also had a new engine and fuel was all redone- average corn - itd make it work- but thats what they are made for |

Corn planted 140,000 around here in this sand would only grow about 8 inches tall. ------------- '49 A-C WD, '51 A-C WD, '63 A-C D17 Series III, 1968 A-C One-Seventy, '82 A-C 6060, '75 A-C 7040, A-C #3 sickle mower, 2 A-C 701 wagons, '78 Gleaner M2 |

| I mixed beans and corn together in my head... I have spots the company that sets up my variable rate has 30-35k set. I don't have prime ground so I bet guys out in ILL are planting 40k now. |

| I would think 40k in 30 in rows would be about like point rows where you got nothing but fodder. |

I used a Farmall 856 non-turbo with a Gehl 800, 2 row wide, population in lower to mid 30,000 range. Some years all could see was the very top of the Gehl 920 forage wagon, and of course the smoke from the tractor. Low range, 2nd gear, sometimes Low 1st but not very often. Keep the knives sharp, set the cutter bar properly makes a tremendous difference. ------------- I tried to follow the science, but it was not there. I then followed the money, and that’s where I found the science. |
