turbo vs non-turbo model questions

[virginiavenom]

okay guys, now I understand turbos. but I'm curious if it is a huge improvement beyond the miniscule hp gains torque and low end torque wise on the L grand series. for example the L4760 vs the L 5460, one is N/A the other is turbo, otherwise it appears engine specifications are otherwise unchanged. would like if the tractor world put out RPM dyno sheets showing torque and hp graphs like cars do. or do they and I just can't find them.

I would imagine the turbo model produces very impressive low end torque vs the NA but could be wrong. for those that have driven both and have conclusions about what works is it necessary, things you find the turbo models or non-turbo models seem to be better at. does the turbo seem to affect the regen rates as I would imagine the 3 cylinder doesn't regen nearly as often as the 4 cylinder which has roughly 40% more cubic inches of displacement.

First it's not considered "miniscule HP gains" 7HP may not be a lot in car terms but in tractor terms it's huge!
They do some testing and graphing of HP and torque curves they are just a lot harder to find that info, and honestly real world performance is what really counts.
In real world performance, yes a turbo does a lot for overall performance enhancement of the tractor. As far as effecting or changing emissions controls or regen times, I think it's still to early in the game to make a solid conclusion on that, my gut would tell me a turbo engine would do better all around as it's already more efficient.

so in what scenarios in your opinion would be better suited for turbo or NA work. I know why the factory did it. cause it's cheaper than building a bigger more powerful engine and it doesn't take much boost to build lots of power...hence the tiny turbo. I know it's significant in tractor terms....I'm trying to figure is it worth the extra coin to get it. wish they would get rid of the emissions crap on tractors....there really is no point. if I'm doing FEL or box blading on occasion or brush hogging with a 6 foot brush hog and blade and FEL bucket, would I benefit at all from paying the extra 2 grand from the 4760 to the 5460? if doing that, should I just go all the way for a 6060? if you were buying a cab L60 would you even bother looking at the lower level models?

Maybe relevant and maybe not. I traded My L5030HSTC for an L5740HSTC and while I have more power, there really wasn't any time I needed more power in the L5030 and run the same equipment under the same conditions. I seriously considered an L4240, but thought I'd be better off with a little more power because the cab.

Year ago when we replaced our Case, I considered an M8540 and M9540, same engine just different fuel settings, same tires and everything, money wasn't an issue, I just saw no need for the extra HP for our needs as they had been met by our previous 80 HP case.

I know conventional wisdom for shed and tractors is figure what you think you need and go bigger; pretty good advice for most, but there are exceptions, the hard part is determining which in which category you fit.

Loader work would probably be my pick for where a turbo would do you the most good, quicker rpm pickup.

I don't think your going to gain a whole lot of advantage for what you sound like you want to do, I do all of that with a older 37HP tractor with no issues. So it's not a mater of just overworking the tractor.

Now if it were me and the decision was between L5460 and L6060 I like the specs on the L6060 better, Loader capacity being the #1 factor, and more HP is always better!

Will any of these tractors work for you, yes they all will, they all have the same basic build, and same basic controls.

Basically it comes down to, do you want a base model upgrade or the complete upgrade!

I'm trying to figure is it worth the extra coin to get it.

Looking at the 4760 and the 5460 on tractor data there are a couple more things I noticed. Not only do you get a 15% increase in HP with the 5460 but it also weighs in 150 lbs more plus an additional 200lbs of lift on the 3pt. The weight and the lift may not be a factor for you but it does show another advantage in the 5460.

The L5460 and L6060 have a Cat. 2 3 point hitch. Not sure if that can make a 150lbs. difference or not but the liftarms and all components of the 3pt. are larger.

OT: We've looked at the L4760, L5460 and the L6060. One thing big problem we're having is the platform and the ROPs have been raised about 4 1/2". The measurement was taken folded down and is 4" higher than our L3940. Most dealers told us that was the first thing they noticed when the L60's started coming in. Our problem is the L3940 clears some places inside the feeder/run-in cattle shed by as little as a 1/4". My guess is it is because they moved the fuel tank from under the hood to under the platform.

a good note, doesn't hurt me really, but a good note, looking at the dimensions it seems that all above a 3560 are significantly taller and longer and wider. although it really doesn't make any difference to me as I have 12x12 openings anywhere the tractor would need to go.

I noticed that as well bulldog. 99% of the things I would use the 3 point for are being pulled, so I'm not sure that will really be a factor.

One thing I have noticed about all the Kubotas I've owned is it's not as much lift capacity but it's holding the front end down. Of course a loader makes a huge difference but like my M9000 for example. With the 3008 Bushhog hooked up as far as lift goes I can't tell it's back there. But I have to put weight on the front to hold everything down. So the lift capacity may not even be noticed but the extra 150 lbs could make a huge difference. It may not sound like much but I only had to add 400 lbs to mine to counter act the weight of my bushhog.
