Need to buy a tractor - concerned about emissions stuff (sacrifice hp?)

[finn1]

Novices often equate noise with power. Ran into this years ago on pickup truck engines. We changed the air intake system to reduce intake noise. Hundreds if not thousands of hours of dynamometer and test track data showed absolutely no difference in fuel economy power, or driveability between the old, noisy intake system and the new, quiet system, other than the intended noise reduction.

Still, there as a certain cadre of customer that insisted that the new system was down on power.

I traveled to Dallas to interview one such customer. We instrumented his truck did did back to back acceleration tests, and even did fuel economy tests on the interstate between Dallas and some town up in Oklahoma. Weighed the fuel tanks before and after with both systems. Absolutely no difference, just like the original laboratory data showed.

When we were done, we shared the data with the customer. His parting comment was something to the effect of “but I can HEAR the difference in power!”.... sounds life the same thing going on here.

Claims and prejudices without data are meaningless banter, and testimonials aren稚 data, merely expressions of opinions.

Many people are fooled into believing that a loud machine is faster or more powerful. I want to see dyno numbers!

That's why I posted the link to the Nebraska Tractor Tests above. They are the definitive authority for tractor data in the world. I'm surprised at how many people never heard of the extensive tractor tests done at the University of Nebraska. I was able to dig up te test data on my old John Deere but alas, the Kubota M7060 I own is one of the models they've not tested.

I don't have a tractor with final Tier IV emission controls....my 2016, 24 hp 2400 barely squeaked under the wire on not needing them. I have a neighbor who bought a 2016 (very well respected with the field service contract and all) 50+ hp tractor that hasthe Final Tier IV emission controls. They only come out a few times a week and their tractor doesn't get run much. They are having problems with the Regen cycle and the RPM thing you mention. Sometimes I see them out just mowing, basically around in circles to get the emission fault lights to go out.

Last year I added a tractor to my corral and deliberately bought "old school". Not sorry. Course "different strokes for differrent folks" (TV series back when), and if your tractor work and Tier IV work hand in hand, greattttttt (Tony the Tiger). My usage won't.

Yeah, you guys are right.

I had only ran the first 255HP machine for 8 years and 2,500hrs. I've only ran the DEF 255Hp machine for six months and 250hrs. What do I know.

I'd buy used. The stories about new tractor warranties ticking away while the tractor sits at the dealer's shop waiting for repairs and all of the emissions hassles has turned me off to new tractors.

I would agree with stuckmotor, IF you can find a good used tractor. If you have the time to wait for the right deal, no biggie. However, when I was ready for a new machine, I spent months waiting because I was terrified of the new emissions with the tier IV. With nothing coming up, I had to take the plunge into the tier IV world. Having owned a Kioti NX4510 now for 1 year, my fears have dissipated about emissions. However if a pre tier IV with low hours came around, I would probably prefer that. For me, simplicity is best. My Kubota B7800 was simple and easy to work on. However, DON'T settle for less than what you need. Good luck in the search.

I like having emissions on my mx5200. When I run my lawn garden tractor, a 14hp mtd, the exhaust burns my eyes and hurts me. When I run my 52hp emissions tractor, I notice no such irritation.

^^^^^^ what he said!

I have been around the new locomotives, new D6-8 cats, and large Deere tractors with modern emission controls, and they are amazingly quiet and smoke free....and I like that. I have never seen smoke from my toolcat except a small amount when cold starting and my throat/lungs appreciate it.

I don’t think a grader that actually gets worked is a fair comparison to a 40 hp tractor that sits in the shed most of the time and only putters around half the time it is used is a fair comparison.
