CT 235 PTO HP testing

   / CT 235 PTO HP testing #11  
The CT235 would turn a 5' rotary cutter really good.

not specific to Bobcat- but some dealers reportedly have pto mountable dyno's to verify a tractors horsepower output.


Have seen another post where the owner thought the tractor was producing well over what it was rated- in one case the pto was outputting more than 10 hp more than what it was rated.- i am sure that owner was pleasantly surprised...

you can also check Tractor Data- and it sometimes has links to Nebraska tractor test labs here- Nebraska Tractor Test Reports | Nebraska Tractor Test Laboratory | University of Nebraska-Lincoln
they do have the CT-450 listed but that is all...?
Hope this is helpful...

Do you remember what kind of tractor this was?

Yes -it took me a little while to remember, but it was a Dong Feng 554 from a post on ( pro boards- Chinese tractor World Forums) pretty sure the tractor is a 55 HP rated tractor and it produced 70 Hp according to the owner, here is the quote-

I got 8.5 hrs on tractor now, so I thought I could safely dyno test it. I warmed it up good, then put it on dyno. It produces 70 HP on PTO at 1000 RPM. I was very impressed. NO SMOKE or OIL LEAKS. I spent about 3/4 hrs on dyno at varying loads and speeds...should be good for the engine break-in.

that would be cool if someone had there's tested I have the CT 225 and I'd be willing to bet engine horsepower is it 28 horse and PTO horsepower higher than rated. I wouldn't even know where to start to get it tested.

Yep- i know I would be.

i think it has something to do with the engines being run for 12 hours @ the HP # they rate them at and also IIRC the YTO engine in that tractor is a larger displacement than most in the 55 hp class

tman
As far as getting it tested i do know i read at least of one member on TBN who thought their tractor wasn't making the power it was rated @ and they had the dealer test it on a dyno and they said it was within specs... so i would guess that at least some of the larger dealers would have a pto dyno...
