Tier 4 is comming... now is the time to get off the fence!

I think a lot of it has to do with manufacture and dealer hype to insure or make a sale of existing stock and justify price increases on new stock. I remember the same hype when automobile manufactures were switching from a carburetor to throttle body and then to multi point fuel injection. Anyone want to revert back to the days of a stumbling, jumbling poor mileage carburetor on their automobile?

ugh. Look, if you want to see whats comming all you need to do is look at anything over 75 HP which already has all the engine do-dadds on it. This keeps ratcheting down year and year so if you want to know whats comming all you need to do is look. I wish what your proposing here was true, but saddly but all you need to do is open your eyes and read about whats happening to on-road diesels and larger tractors to get a broad unbiased view of where we are headed. unless your sole criteria is emmissions, its not good by any measure.

I have talked with a lot of truckers who have been dealing with this for several years now and not ONE has said 'boy I am sure glad for all this emission stuff'. It has been a nightmare with huge expense and tow charges.

Thanks for the heads up. I think my 2006 John Deere 6415 just went up $2K! :laughing:

I love fuel injection on gasoline vehicles. I think if it were not for smog reduction and EPA requirements, we'd still be driving vehicles using carburetors and inefficient fuel/air mixtures. When fuel injection started appearing on cars, it was accompanied with a large price increase. However, in the long run, I think fuel injection has been great for fuel economy and reliability. Between fuel injection and high energy ignitions, the tune-up mileage for most cars is every 100k mi. instead of every 15k miles. I DO NOT miss the days of changing points, plugs, and doing carburetor adjustments or fixing stuck floats that dumped raw fuel onto the top of a hot engine. I will lead the cheers for electronic fuel injection, electronic ignition, and performance control computers. When you could buy 4 gallons of gas for $1, it was fine to push those big block fuel guzzlers up and down the road, but I thank my lucky stars that all my vehicles get 20+ mpg today.

I don't know if DEF and Tier 4 will lead to improvements in diesels that can be compared to improvements in gasoline engines. If it does, the first generation will seem more costly and will see lots of resistance. I don't think diesels ever showed performance problems like gassers prior to fuel injection/elec. ignitions. However, if these restrictions drive innovations in diesels that compare to gasoline engine improvements, I'm very excited about the future of diesels. The jury is still out in my opinion. . .:confused3:

Actually fuel injection (both mechanical and electronic) predate smog standards by decades. The problems were mechanical injection systems weren't reliable and electrical components couldn't handle the heat and vibration very well. It wasn't until about the 70s before we overcame the issues so electronic fuel injection was possible. The point is there were several companies, Bosh for example, that were working hard to be the first to develop a reliable EFI system for the auto market. Unlike now where technology is being invented to comply with new laws that will not benefit the engine or vehicle in any way other than emissions back then they were able to use a maturing technology that was being designed to increase engine performance to also reduce emissions. Sure the new emission standards helped speed the automotive world up in adopting EFI but it was already heading that direction. Just like EFI electronic automatic transmissions, sat nav, power windows, etc all came about because they added an advantage the driver wanted.

We have 2 brand new 180hp tractors now , One JD and one ford both of which are less than than 3 months old and both have been called back for fuel/computer problems to the point where they are unuseable I personally am not convinced by this "buying new" but times move on !
2 years ago it was a new valtra same thing ..always computers and electronics . The downtime we lose from new tractors with "fully loaded electronics" are far more than the 20-30 odd year old tractors we run on the farm which do the same hours .

Will this include diesel UTVs? Been wanting a diesel JD Gator

There is a HP break where Tier4 can be met without all the added goodies. I believe these will slip under that limit.

When the US went to unleaded gas did they add 3000 bucks to the car price?

I know the AIR systems upped the cost back in those heady days, but they didn't carry the computer and complex sensors in use now

And if you add in the inflation from then till now, 3K seems about right in cost.

When will this affect diesel zero turn mowers? The Ferris 5100, comes to mind.
