New tractors on the dyno. Which brand does best?

[screamin400]

I am comparing tractors of all colors and wondering if anyone has put an almost new tractor on the dyno to see how it did against it's specs? I wonder if any brands cheat it a little bit.

Believe that as a general rule of thumb, the manufactures are sincere and honest in their HP and torque output values. To be caught exaggerating those numbers would be much more devesting to their reputation than any benefit that could be derived from inflating those hp and torque values. Don't believe this is an issue worth concern or consideration.


VW Did NOT exaggerate hp values. My neighbor was required to sell his vehicle back to VW per GOV mandate, He bought it slightly used from VW Dealer for $19K. VW wrote him a check for $21K
He was so upset, he immediately purchased a brand new VW. The new car does NOT deliver the previous 52 MPG, sadly. Most effected VW owners surrendered their vehicle ONLY because of the legal Mandate.

Nebraska Tractor Testing generally does NOT include compact tractors. It is very expensive to participate in those tests and outside of the farming community, most consumers could care less.

As a private citizen - - a dyno test??? - - to what end??? I think the OP needs to go suck up more diesel fumes or roll more coal.

I put one of mine on a dyno when it was almost brand-new...

It is factory rated at 56 pto hp and I took it to a CIH dealer (it's an AGCO) to be dynoed to rule out any bias...

Anyway, it sat right on 60 hp for one full hour at pto speed... And it sat on 70 hp for the 15 minutes at wide open throttle when he opened it up. He didn't want to run a new tractor longer than 15 minutes at WOT...

Anyway, the service manager who dynoed that tractor was impressed, and he said it would pick up a few more ponies after it had some hours on it, and it did.

Not sure what you brought to my post with your senseless useless drivel.

Any tractor manufacturer advertising X power, but deliver less, is committing consumer fraud and would be subject to a class action law suit, not to mention reputation damage.

If new tractors were tested on a carefully calibrated dynometer, as in the Nebraska tractor tests, I feel confident new tractors would hit at least the promoted number with minor variation over the promoted number.

What tires you select for your tractor will be much more important than minor power variations over spec.

Sawyer...
Back when my dad sold Allis Chalmers, the AGCO ancestor, they always underrated their tractors...A D17 was marketed as a 50 HP tractor...They pull 53 to 54 at the PTO...They had a Dyno and would check them... Typically they were underrated 10 to 12 percent from the actual PTO HP output...At least on your model this is still true...

I have had many tractors over the years. Most have been on the dyno one time or another. I will be looking for something in the 75 pto hp range. If a certain brand runs 5 under and another brand runs 5 over that is a big difference for the money. I do not want to have to purchase 85 pto hp to make sure I get 75. The Nebraska charts are nice and I had forgotten about them. Thanks above for the reminder. I was hoping to see something for Kubota but nothing really there.
