Have you seen the new CK2610?

The HP will most surely not exceed 26HP unless Kioti wants to get their butts fined out of business. The EPA emissions tier stuff is strict. It has been common for companies to de-tune or de-rate engines in order to offer models that fall under the 26HP Tier 4 Final limit, and can remain Tier 4 Interim.

In some cases it's possible to drop the max allowed RPM to stay under the HP limit, so the rest of the engine performance is largely unchanged. I remember seeing that with one tractor that was derated from 28HP to 26HP. When there is a larger HP drop, they'd have to be doing a lot more than governing max RPM.

I don't think the detuning is that complicated. All they need to do is limit max fuel delivery so that max hp cannot exceed 26hp. If they did it this way it would have little impact on the bottom half of the RPM range. Max hp could come at say 1800 RPM and then just stay flat to 2600 RPM as no additional fuel would be delivered. Hp at 1800 RPM could be the same as the 35 hp (@2600 RPM) variant. Sounds like a really nice offering in a mid size CUT.

I think you should be good to go with the CK2610HST. I'm curious, why do you think real hp is higher than rated hp? If they detuned peak hp for emissions it probably is what the specifications state. However, just because they detune peak hp doesn't mean torque at lower RPMs needs to be any less than the 35hp model. What this means it will likely have great torque reserve. It will resist lugging down more than other 26hp tractors that may have smaller blocks. This will make it feel like more than other modern 26 hp tractors. More like tractors of old! Which is a good thing.

Just my "butt dyno" based on accelleration in high range of each the 2610 and the 3510 on the same hill being very similar.

Yes as Gitty up has said, with mowers, tillers, & blowers if you are trying to push the largest one possible then you need hp. It's nice to have plenty of hp for what ever you want to do though. If you think you might want to do a lot of mowing or something then I would recommend around 5 PTO hp per foot of what ever you want to run as a general guide. But some guys have never even used there PTO so for them this would be a nice setup.

I thought it is one foot of implement per 5 engine HP. At least most size recommendations I've seen support that ratio, roughly. I know there are many Kioti users that are quite happy with their implement performances to that ratio. But, I don't claim to really know, and my PTO experiences with my CK hasn't been extensive.

Another user data point: For a while, I had a 66" snow blower on mine. I couldn't get it to bog down. I'm sure if the snow conditions were big enough and I moved fast enough I could get it to bog, but I never had those conditions. I have a 6' Gannon box blade. Very heavy ~1000 lbs. Digs excellent. My CK25 pulls that good too, even when full over the top. So I think a 2-bottom plow would be OK.

Opinions vary and most tractors will run implements with that ratio. Problem is the difference between engine and PTO horsepower varies greatly. With Hydrostats it is a much larger gap. So generally speaking using the PTO horsepower rating is more consistent as a base point for power needs. You can absolutely get away with less and you could absolutely get away with more. It's just a guide to get maximum performance out of a specific implement. I have approximately 20 PTO and I run a 5 foot bush hog and a six-foot finish mower. It does not fall within the recommended guidelines but it performs fine for my uses. It would however perform better and get the job done faster with more PTO horsepower. Just all depends on what you want.

Looking at that Spec sheet, it appears the new model has an engine with a smaller displacement. I imagine they just bored the cylinder walls to a slightly smaller bore, and used the same block as the 3510/4010. And the new 35/40 hp models now have Turbo-chargers?? I am jealous, I bought a CK3510 last fall, and I could have held out for a cheaper 26 HP model, or gotten a turbo on my 3510. Interesting though, that the engines are identical to mine on the CK3510/4010, but they added a turbo, which achieves the same HP at the same RPM on the same displacement? what is the benefit even.

I take that back. Drove the CK2610H and CK3510H back-to-back today. The 3510 is much smoother and it is noticeably more powerful, especially at higher throttle. Feels maybe a little more refined as a result.

I looked at the 2610, 3510 and 4010 gear versions up close today as I am wanting to replace a 15 year old gear Cub Cadet. The 2610 is intriguing with no emission BS at all. Looks like a great candidate for a small turbo boosting the power in the 40s one could assume.

All 3 tractors looked identical except for the power plants. I did notice one with turf tires but they are quite narrower than I expected and wonder about tearing up the lawn which is the main reason I use the tractor for. They were all bulged out in the centers like they are way over-inflated.

Anyone have a picture of the turf tires on the CK2610?

Later today I'm picking mine up will post.

I'm hoping you don't hate this tractor.
