Too much hp?

I was looking for an older 7000 series allis with a cab that was around 100 hp, maybe 115-120 at the most. I have seen that the 7000 and 7010s sell for more than the bigger 7030,7040, and 7045s. Is this because people don't want the bigger tractor? Would this tractor be too big for running an old 20ft batwing and a sqare baler and round baler? I was thinking that I could get a 21 spline to 6 spline and run the 540 rpm implements at low rpms to save fuel and have less wear and tear on the engines. How much bigger of a repair bill will I have with a 426 cu in engine compared to a 301, all 6 cyl? Would it be better to get a tractor this much more powerful, that way the drivetrain and engine would last longer? Any input is appreciated.

We had aJD 15 foot bat wing an used a case 1070 with dual pto. Had 1000 pto on mower an was trouble free till put 2390 on 160hp an broke main gear box . Recomend mower with 1000pto . iooopto isa much smoother reliable way to go on mower. As for throttleing back dont even try it. look wor tractor with dual speed pto around 100 hp

The 7045 has dual pto, I was just concerned about economy and fuel usage. Thanks

My neighbor tried the 1000 pto at lower speeds with a 1570 Case. There were pieces of the haybine scattered across the field after a few minutes. Got in to some heavy hay, had to throttle up to gain more pto speed, went to far with the throttle, and ka-boom. Don't do it.

I had an Allis 210 with 1000 rpm pto and I used an adapter on it and ran the round baler and mower conditioner with no problems. If I were buying a big Allis, I would buy one with a 301 engine over the 426, I just think they are a better engine. Mine went through 2 426's.Tons of power though,I never dynoed it ,but field compared to my neighbors JD it must have been up around or just over 150 hp.

I don't know much about batwing mowers, but I can't imagine that it takes over 100 hp to cut 20 feet of grass, and you can certainly run balers with half of that hp or less. You can cut grass with a 7 foot sickle mower. Big tractors are fun to run, but expensive to repair. So if you have a major repair, what does that do to your car-saving budget? As far as running pto at half speed, I think that's just asking for more ($) trouble.

You are probably asking for trouble twisting an older batwing with big HP.

I forgot to say what I was getting the tractor for. I was wanting something that I could use to make some money with. My dad has agreed to let me use the batwing, so I was thinking of mowing some pastures to make some money after work in the evening to save up for a car in a couple of years. What do you all think? I am 15, so I don't have a lot of money to blow. If anything I just wanna break even on my investment and be able to keep the tractor. What is your all's thoughts?

Thanks

The 7000 series tractors have a reversible stubshaft that runs at either 1000 for the 21 spline and 540 for the 6 spline.

I spent quite a few years on a 7010 and the neighbor has a 7045. His 7045 has a 540 pto shaft. We have used it with a manure spreader and a 16' batwing mower many times. In physical size, I can't tell any difference between the 7010 and the 7045. Big difference in torque. If you can do it for the same price, go with the 426 motor. I don't remember the 7045 being any harder on fuel than the 7010 unless you really worked it hard which you don't seem to need to do anyway. Either way, they are all cheap hp and comfortable tractors with nice cabs. I'm not a big fan of the trannys in these tractors, but you can't beat them for the money.

Any of the tractors mentioned would probably be all right for the mower and BIG round baler; sounds like a lot of tractor for a "conventional" square baler. I agree with the others; forget trying to run 540 equipment with 1000 rpm tractor.....

I would be running a 4x5 ft M&W round baler, that is the biggest baler we have. The batwing is a 20 year old mower, so it has the older, weaker gearboxes. That is why I am concerned with the bigger motor, it might be too much torque on these older machines. Would probably hardly ever use it to run the square baler, open stations are better for that so you can hear if something goes wrong. If I understand correctly, I should get around the same economy as a 7010 pulling the same thing? Thanks for your help. By the way, the 7045 has the power director trans, not the powershift.

I'm not so familiar with the Orange tractors, but I have an 85 & 140 hp Blue tractors. I run about the same stuff you want to, no batwing tho.

Throttling back has it's problems. Not the best. You are missing the power curve of the diesel engine. Especially so if you have a turbo. Can do it for an emergency, but wouldn't want to plan for it all the time... Most tractors ubnder 150 hp have both options, change the stub pto shaft & get the other pto speed. Would Allis have this option as well? Both my Blue ones do.

The bigger Blue tractor has a longer frame, different steering radius, just designed for more heavy all day tillage. The 85 hp tractor is much more nimble, much better turning, etc. I would not want to run a small square baler with it, just not as manuverable.

Typically the bigger units use a lot more fuel per operation, so you will be less efficient. Assuming you won't be running it 2000 hours a year so probably not a big deal.

You can't run a tractor with a 1000 rpm PTO at a low enough rpm to use most of the older equipment. A baler for sure is a NO NO. When the govenor on the tractor kicks in, the baler is going to fly in several directions. Oh it may not happen the first few times, but it will happen. I get equipment all the time that has been torn up in just such a way. On second thought go right ahead, stupid tricks like that keep me in business.

Forget the idea of throttling back atractor with 1000 rpm PTO to run 540 equipment. You wil tear up allof your equipment like my neighbor did. You might use it on a sprayer but never on even a borrowed baler or rotary cutter.

Forgot to say, the 7030 is 132 hp, 7040 about 135, and the 7045 146 hp. Thanks
