Not using all my horses by design??

If you are running a PTO implement, you'll have to run PTO speed regardless. I assume it doesn't have 540E PTO like some tractors do, so you can actually get 540 PTO while at a much lower engine RPM?
I can run 540E on my tractor, use less fuel, and have plenty of hp... But without it, I still have to run 2500RPM to get 540rpm from the PTO, whether I need the power or not.

48hp and I burn 1gal/hr

I don't beleive it has 540E. However to turn the engine with a low load at the appropriate rpm would still be less fuel I beleive then fully loaded. That said, I still am wondering if there's a fuel advantage to doing that and or a longevity por/con to running like that.

Does having too much HP potentially cause problems if you run the engine at a lower rpm because you don't need all the HP and maybe then have more regen issues?

I have ZERO regen issues because both of my tractors are pre 4 and I'd never buy anything else any way.

I rarely run either of mine at 540 pto speed actually and one of mine is 540-1000 and I use the 1000 rpm 21 spline pto stub to run grain legs and such.

I'm not sure if that is to me or not. The HP is rated at 108. I am not mistaking that for torque. The peak torque is at 2206rpm on this engine, but I forgot the number.

With that, my use range would be significantly lower as I don't need that much power for pretty much anything I'm going to do or use.

No that was not for you specifically. That was for new tractor owners who fall into the siren call of HP. If you are paying for a tractor JUST because of HP its a good idea to make sure that HP is made at a reasonable RPM.

The HP trap is real!

Most of my implements and plan to purchase implements need about 40 to 50hp. Hence the question, run a 60hp tractor flat out all the time, or barely work a 108hp tractor.

With a new emission diesel engine, you are better off to buy "just enough" horsepower and run it hard. Or you will be doing lots of regens.

At around 75 HP+, most (all?) tractor diesels need DEF to meet emissions, so that is another layer of cost to weave in.

Regen: where you burn more fuel to attone for the fuel you have already burned in order to reduce emissions on small tractors which have virtually no impact on the environment. In the grand scheme of things, there are simply too few in operation for too few hours and widely dispersed for all of the effort to do anything more than make someone think they are 'helping'.

What all are you wanting to do other than mow?

A Ventrac was built for mowing steep hills and it can do may other tasks well. It comes in gas or diesel.

There's no DEF or regen cycles as far as I know.

Till, disc, hill, pull some big lumber here and there, operate a BH100, and not mow.

I also have to construct my camp with it. Gravel, holes, digging power/water/air lines, moving stuff, leveling dirt etc.

If it's new and 108 horsepower like you say it is, it will have both SCR and DEF injection.

Starting to think you are blowing smoke.

Hey. I don't recall saying it's new. I did say it has 1300hrs though. It does not have DEF. It may have a scr though. No regen cycle as far as I know.

No DEF fluid in the 7060 you listed, but M5 and larger Kubota's use DEF fluid along with the DPF and all do regens.

I see this specific point is exceptionally important for you. The tractor I'm looking at is a 2007. 2008 is when the EPA started the general requirements for DEF and regens with it rolling into pretty much all tractors 70hp+ around 2013ish. There were early adoptors in 2006/7 but this tractor wasn't one of them. Again as this tractor was prior to the EPAs DEF emission for the HP class, there is no DEF or regen that I am aware of. Theres also no DEF tank and the exhaust comes right from the back of the turbo and exits below the tractor from the factory - no catalytic converter....

Im hoping we can get off this side track and back to the initial question I asked for help on.

What? Stay focused on the question. Ah-er-uhm.... do you know who you are talking to here - lol
PS: Torque nut this is for you.
We all know what torque is and what hp is. Hp is a ridiculous measure of power. But hp is how tractors have been rated and categorized forever. So we use it knowing full well that is is not the same as torque. Sheesh.
Stay focused

Sorry it just sounds ridiculous referencing the need for HP when plowing. Its like bragging about a 500psi air compressor that only holds 1/100 of a cubic foot. Lots of pressure but cant do any work. Any reputable tractor manufacturer will list their HP and torque specs i just suggest you give them a look before buying

Please stop hijacking this tread. This is in no way related to my initial question and should probably be it's own post. Scootr is correct in that the industry operates on HP ratings for equiptment and tractors. Regardless of its erroneousity, it is the industry standard and the basis of the question.

Does any one have information on my original question without all this side tracked trolling?

 

[scootr]

Over the years I've had three 50 hp tractors and a 50 hp Skid Steer. This category is what I call full size.
I do mostly ranch maintenance, road maintenance, light to medium grading, and material moving.
Most of that work could be accomplished with a smaller tractor but I grew up on a Ford 455 and MF30B.
When you need the power it's nice to have it. Honestly, sometimes I wish the MX was bigger and sometimes I wish it was smaller...so I guess it seems just right.

Good luck in your tractor buying hope you figure out your question.

Just LOL.

I try not to put people on my ignore list. But you are making that difficult.
Quote this post to start the list. Have a nice day.

I'd be honored. Never had a full sized tractor owner put me on ignore before.

Sure. We all know the answer. I think you do too.

Since you are looking at a pre emissions model, there is no downside to running a higher hp tractor at a lower rpm. Old style pre emission tractors have flat torque over a wide RPM range, so using a larger pre-emissions diesel at lower rpm will just end up taking a little longer to do the job and burn less fuel in the process.
No real downside for individual use. You can even use lower HP implements that way.

We run our 90 hp pre-emissions tractor at about 1/3 rated rpm when not using the PTO. Since the torque on that engine is flat from idle to full rpm, it becomes a rather heavy 30 hp tractor and uses proportionately less fuel. For PTO use, select a lower gear.
