Bingo.
My question exactly.
The interim Tier IV standards affect this HP range as of 01/01/2014, and other manufacturers are getting their ducks in a row.
If the federales have written the regs as they did for other so-called "pollutants," it is possible to buy/sell/trade "credits" (to enrich folks like Algore). Perhaps, JD, like Bobcat, has bought "credits" to delay the inevitable.
Time will tell.

Interim Tier 4 for the 25 - 75 HP range has been in affect since 2008. None have DPF (Diesel Particulate filter or use DEF with Selective Catalyst Reduction. the DPF or DEF use came in for the It4 specifications in 2013 for the 75+ - 150 HP range. The 25 - 75 HP range is what we are seeing coming into production this year, became affective Jan. 1, 2014.

Well like Kubota is still making M108s due to credits.
Kubota made the SVL75 up to the last day cranking them now. The new one is the SVL-2 with emissions.

Yesterday I visited a dealer that has both open station and cab versions of the 4720 in stock and he is working on quotes for me.
Thanks for the link to the NE test. The test is dated 2009. Anyone know if engine specs have changed in any way since the test was performed? The JD brochure rates the 4720 at 56 PTO HP but does not specify engine RPM.

Depending on what you want to do they can be a great tractor or a horrible one. AC filter design is really lacking.

JD "turned up" the power on the 4x20's in '09, and they haven't changed since. JD has a tendency to actually under rate most of their tractors, so I always check the Nebraska test data.
Another thing nice about the test labs, is they have the torque rise and the fuel economy numbers. You can see that the JD Powertech engines have impressive torque numbers and good fuel economy compared to a normally aspirated engine.
I think the cab will cost you about 8K. For me, I wanted to be as manueverable and handy as possible for livestock chores and bush hogging, so I opted for no cab.
