The new dealer who bought out my old dealer is the nicest young man I've had the privilege of being associated with. I never thought it would be possible that anyone could take Chad's (my old dealer) place, but this young man has. The statement you made about wondering why I had not demoed a new Super Z also got me to thinking, so I called my new dealer Ben McAlister. He told me the demo he had was just sold, but he would do everything in his power to get me a new Super Z to try and see what I thought.
I am truly surprised at your fuel usage; your numbers calculate to 1.88 gph, so say 1.9 figuratively speaking, which is very good in the thick moisture laden grass you cut. I take it you have the FX1000V and not the FX1000V-DFI, is that correct? This tells me what I wanted to know, especially since I believe you to have the FX1000V, which is not equipped with the electronic governor. They've definitely made progress with their excessive fuel usage on their big block engines if these are the numbers you are seeing.
I heard many say on the older 37's they saw them use 2 to 2 1/2 gph depending on what they were cutting. The older 37's I operated would drive you crazy listening to the engine run, and I brought this out to Kawasaki. This engine sounded as if the governor was hunting at all times, it was constantly activating the governor in grass where the engine should have never changed sounds.
With this latest demo, 31hp Kawi SuperZ. I put it to work a little harder. Up and down hills I do side to side with mine, plus the thicker Spring growth.
The 31 is NOT enough. It was more the hills then the grass.
Wish they'd find a way to make a fast mower with more efficient hydros.
The flex forks are now much stiffer. Maybe with the machine weighing considerably more, they had to stiffen them up.
I put 25 hrs last year on this demo, and 12 this past week with the flex forks. I returned it yesterday with 42hrs on the clock.
This demo showed me that I need to be looking at the EFI Lazer.

You and I are diehard closed-loop efi, and if other people got a chance to see the difference, they would be turned around as well. Then maybe we could get the attention of these mower companies "SUCH AS HUSTLER" to become more interested in their engine selections. I understand they are trying to go with the name that sells, but Kawasaki is not nearly as popular as it once was, and if anyone had the chance of running the same mower with the big block Vanguard beside the Kawi day in and day out, I can promise their next engine of choice would be the Vanguard.
I honestly find it very hard to believe the EPA has not forced all mower engines to be of closed-loop efi design. The efficiency and pollution factor is so far advanced to what is being used today, and that includes Kawasaki's Digital Fuel Injection, that it should by all rights be mandatory by a certain date. A date I believed would have already come by this time, which makes me wonder if there is money changing hands under the table.
Not to mention, this particular Kawi (the old 31hp) and a previous (old 29hp) on a Demo Lazer were VERY loud in terms of internal engine (valvetrain) noises.
Oh, and speaking of weight....
Don't know the exact numbers, but these newer SuperZ's are NOTICEABLY heavier. So much so that I can FEEL it when I tow it on the trailer!
Here is an email reply I just received today from Kohler asking for more EFI choices.....
Thank you for contacting Kohler Engines!
There are plans to expand fuel injection to additional engine models in the foreseeable future and we hope the equipment manufacturers will agree with your logic. Specific dates are not available at this time.
Puppy, those numbers were from cutting "average" grass but all on slope. If cutting average grass on flat ground I would expect better than what I got.
The engine is loud, much louder than the 31 but it is a better sounding loud if that makes sense? Watch this vid and listen to the engine, it barely struggles and I dont here the gov' kick in at all. Some of that grass at about 2.15min was 2' tall or so and thick.... http://youtu.be/XjR5pDmJHXY There are a few other vids if you want to check my channel. Warts n all are what there called.
I agree with both of you about EFI, I held off buying as long as I could due in the hope they might bring one out. My first SZ was the 28efi and it was a good engine although under powered for some of what I do. No way would it handle these new hydros!
This SZ was going to be a 37dfi but something changed before release. I find it difficult to believe Kawi cant supply enough engines when other Manu's can get them. I have also heard Kawi are't keen due to the hydro cooler over the engine and potential for over heating. I personally cant see that really being a problem myself but, who knows?
If I had a choice between a Briggs or Kawi I would of gone Briggs. If I had a choice of carb'd or dfi/efi I would of gone EFI.
TLS, I agree about the weight. It is noticeably heavier on the trailer for sure! The new SZ is close to 100kg heavier at around 680kg from memory. Still lighter than a Turf Tiger though at around 750kg.
Jason, sorry about my silly little joke! Proof one should not drink and type!
I don't know what I will be able to figure out from this mower because of excessive power, but they are bringing me a new Super Z with a 60" deck and a 37 hp Kawi. I find it somewhat hard to believe they would put the 37 on a 60" deck, but we'll know next week. I will tell you precisely to one-tenth of a mph exactly how fast this mower is on perfectly flat ground with blades off. They are advertising the Super Z at a hard number of 15 mph ground speed; I am expecting it to be within 4 to 5 tenths of what they are advertising. I want use GPS, but will use a perfect distance and elapsed time which is the most accurate calculation for speed. My dealer is also interested in the speed information as well, when he tells a customer he is buying a 15 mph mower, he wants to believe these numbers are accurate.
The 60" 37hp is probably about right. The 31 was underpowered. The hydros are what works it so hard, not so much the width of cut.
