Pto hp into balers

Looking at a second and tractors to suit our operations , and just wondering about pto hp into implements.
So tractors will be for mowing and baling mostly ( round and possibly the conventional if required , tedder and rake )
Was concerned that too much hp from the pto could damage the balers. Two hp ranges I was looking at was 150 hp and 180hp.
The bigger machine has front linkage with obvious advantage , but would we be better to go smaller so we don’t overload the balers , or does it not really affect balers?

Looking at jd so only three speed pto , bigger machine gives more options for future , but we don’t want it at expense of wrecking balers
 
I expect most modern ,high output,high density balers want at least 120 hp on a flat field. Our baling tractor is about135pto hp and it's on its limit on steep ground. The balers would all have slip clutches etc

Yes all have slip clutch’s and shear pins , but have been told by a local baler agent about two new round balers sold , one behind 130 hp the other behind 200 hp , one no issues, the other respectively numerous breakdowns on input shaft , gearbox etc.
I understand that the protective devices should all be ok , and some drivers are rough. Just seeing what people’s experience is in this situation. I guess the big question is , can you have too much hp

Horse powers are nice to have and you don’t have to open all the stable doors at once 😜 buy a tractor that will be on top of all your tasks and still fit easily in buildings etc

The only damage with that horse power into any of said machines ,
will depend on the interface between the seat and steering wheel and controls 🙄 ,
🙄🙄🙄🙄oh i see tr250 beat me too it did not read other posts 🤫

Yes we are all hills , that is why upping hp , not running a combi however , but would get away with 130 on round baler , but looking at jd 6930 so 155 to 180 hp. Was a bit more worried about power transmission to conventional baler if I needed to chuck it onto that. I’m the only driver of baler , though I am teaching my teenage daughter to do it , so we are very gentle on equipment.

As said above a conventional will be shearbolt and slip clutch protected. Drive it like your tractor is 70hp and you will be fine.

A wee bit if mechanical sympathy ad big hp won't be any harm. I used to bale with an mp130 deutz with 160hp. Only major damage I done was a gearbox on it, only had 100hp that day if I was lucky and some hills. I worngly thought the baler would kill the tractor before something broke where as when 160hp I knew not to use them all.

Remember a profi article from near 20 years ago testing load on balers as the bale formed, at the balers peak in the cycle demand was something like 137hp.

Did 4 seasons with a MF 7618 (180hp) on an International 440 from the 80s, drive at the speed the baler is comfortable with and it will be fine.

I actually think it was easier on the baler than a 50hp tractor that was being dragged down and surging on the revs under loading, constant speed broke less shear bolts.

No need to rag anything, can go steady if there is loads of spare power.
 
We often bale steep slopes and our vicon rp2235 baler would soon suck the power out of forward momentum of the tractor (deere 6900) soon should be powered by the mf7495. Roller baler obviously and knives chopping all bales. Far more power hungry than our old deutz mp130

Belt baler takes no driving even with knives in, big fuel saving compared to roller baler. Has the op not got a 135 or such like to use on the little baler? Father does most of the little bailing here with a dexta all 28hp purring away. Find visibility is bad on big tractors when little baling.

I've thought this out like this.

The more hp you've got, the less the output fluctuates. For example, 180hp will clear lumpy bits on swaths with less "hassle" than 140hp etc. So the forces put through the pto shaft are much more even on bigger hp tractor.

I might be wrong though. :scratchhead:
