Tier 4 is kind off old news now in the farm tractor world (150+ pto hp), has been that way for a bit. I think the tractor folks have done a better job reacting to this than the on road truck industry. Prices certainly went up but in the process many of us learned that based on how the hp was used in previous machines that units where drasticly overpowered for the uses they where put to based on the computers logs. Some of the new approach is utilizing more of the engines cababilites instead of our thought that more power is better and that working an engine hard is bad. As noted earlier we still don't know how this affects overall engine life but the puchase of tier 4 row crop tractors has not slowed one bit and with these requirements there are additional great improvements being made ie. sequential/variable geomotry turbos, etc, etc. Hopefully we see some extended features that benefit the user more than the gov't with lower hp units as they are added (I think we already have, many cuts are now using ccu's, ecu's etc I believe this is a plus). One thing is for sure is that when large frame farm tractors went this route late model used machines gained in value substantailly. As there are more and more tier 4 units out there and the fear goes away those late model used machines declined in value (somewhat). The price increases for machinery is getting staggering and not all of that can be blamed on gov't engine restrictions everything is just getting more and more expensive. Not necc the best comparison as AG users have to have the equipment where homeowners may just want the equipment. My two cents, not necc acurate just what I percieved.
Tier4 doesn't bother the large farmers because they don't own the equipment. Most of it is on lease (warranty) and if it is owned, it will be owned by a co-op. It's also just another "cost of doing business" to them and is passed on to the next purchaser in the food chain.
The folks that will really be burned by T4F are the folks who buy a piece of equipment with the intent of it lasting them for the rest of their lives, which is many of us hobby farmers. The increased costs in maintaining just the emissions system long term will be a "no-go." Many of the small time farmers in my area will take themselves out of the market before they are forced to buy a computerized tractor, much less one with a turbo, DPF, EGR, or one that takes yet another new fluid to keep on hand (DEF.) If they can't repair it on the homestead or farm, they won't own it.
I simply hope for the sake of my dinner plate that when they do remove themselves from the market, someone else will be ready to step in. I have a feeling it will be a big time co-op who doesn't even own their own equipment.
Why did the rail and marine industries get a pass on Tier IV-F?
If we don't slow down the regulators and get common sense back into their equations, we may just see them regulate us into financial extinction.
I get highly annoyed at this whole movment when they do things like this that make so little sense. Why not tackle the biggest causes (like farting cows) rather than waste our time on such insignificant sources.
