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.

Looking at the Nebraska test report (found at: http://tractortestlab.unl.edu/c/doc...8-42f3-a469-583d60ecbfd7&groupId=4805395&.pdf ) is says that 540 PTO is 2404 RPMs on the crankshaft. This matches the Deere site (here: John*Deere 4720 Compact Utility Tractor 4000 Series Compact Utility Tractors JohnDeere.com ) which says that the "Rated engine speed, rpm" is 2400.

It's only a guess, but is field cutting why you are wanting the HP? Reason I mention is, you are used to older heavier tractors which were aimed at ground engagement and while these newer tractors can do it, they just don't have the weight to get the drawbar numbers a heavier tractor would have...IMO..But to spin up a shredder and get after it, they are awesome. Lighter weight is easier on your fields, and I would love to have a cab model to mow before church.

No. I plan to use it mostly as my "first round, cut in" tractor. I have several areas that are heavily obstructed with trees, etc and spend a great deal of time reversing and changing speed making the first round or two. A hydro would be ideal for this work before switching off to a larger tractor/mower combinatioin.
That said, if I found that the 4720 could handle my Woods BB840 (7') as well as my Woods BB720 (6') cutter, I might decide to use it for both and sell both my 45 PTO HP MF 533, currently used with the 6' cutter, and my 60 PTO HP MF 2635, currently used with the 7' cutter. Weight and lift capacity is my main concern in this regard as the 7' cutter is CAT II, heavy and long.

4720 is CAT I only.

Are you sure about this? I have done a good bit of research and there are a LOT of conflicting stories out there. However, JD's own manual for the 5000E line tractors (45-75hp) that were just released (now available with cabs and PR transmissions) have them as Stage 3A - not Stage 3B (aka IT4): John Deere 5E Series Tractors
To the OP: Have you considered a new 5055E with the PowrReverser transmission? Plenty of PTO HP there for you, as well as much more weight. It's not hydrostatic, no, but the functionality of it is pretty close and could be a good trade-off for you with your desire for something that can run some of your 6-7' attachments with ease. :2cents:
For my purposes, I much prefer a hydro and will likely not make the move otherwise. If I were to consider a hydraulic reverser, I would likely go with Kubota or CNH from my local dealer.
The CUT is desireable due to improved maneuverability and small overall size to drive beneath and between trees. I currently have a 60 PTO HP MF with synchro shuttle which is more than adequate in the less obstructed areas.

Have you looked at the twin spindle mowers from Bush Hog and Land pride? They require less horsepower to run and do a great job of mowing and are offset to make trimming easier.
I currently mave a nearly new Woods MDS 1260 HD 10 1/2' cutter that I plan to sell as I have sold the tractor that I used with it. Six and 7 foot cutters are about the limit for many of my areas due to obstacles, though I may consider an 8' twin spindle once I make room by selling the 1260.
