I have a 450 with 52 hrs. on it. It ran great until about 45 hrs. then started puffing and hard starts.

I figured it was a bad glow plug or injector, Dealer told me just to cycle the glow plugs twice before staring. Once your tractor started did it run ok, or did you still have smoke and problems?

It took a lot longer to warm up compared to when it was running well. But it does sound ok after it's warm. Dealer said that under a load it would be fine cuz the engine would be able to burn the extra fuel. He also said to change the engine oil due to the extra fuel flooding the cylinder with the bad injector.

Im curious to the injector fix, I doubt that is my problem. Mine has did it from the first day I picked it up. I have started ton's of 50hp bobcats on lots of dealers and they all start rough, esp the SST models.

I had a 40hp hydro bobcat for a year and aprox 120 hrs and it started perfect.

Tractors coming back from the shop today. They replaced a bad injector and reset the timing. They say it runs great now. Injector was on back order till the end of December but they were able to find one at another dealer.

Well let us know how it starts up. Mine still starts very hard, but i have marked the dipstick to see if there is fuel in the oil

Runs great now. The timing was off as well.

Question is how does it start, and how cold is it where yr at?

my brand new ct235 has the same issue, hard starts knocking etc, my previous ct225(25 HP model) did not have these issues
