Problem with gt 2550

[pingman137]

Can someone help? When I pull the pto knob the mower goes dead. It takes about three tries to get the blades to work. I have had the mower for one year and it has 12 hours on the meter. I love the mower once I get the blades to turn. I have checked under the deck and it is very clean.

Are you giving it enough throttle? Run it up to at least half-throttle or so before engaging the blades. If it still stalls there must be a bind somewhere.

My GT 2544 needs to be warmed up (engine) quite a bit before I can engage the deck PTO.

Run it half choke at first then once the blades are up to speed, no choke...sounds like you havent warmed up the Kohler

Pingman 137...
I have a cc 2554...and use to have the same problem.
Now, upon start up, I engage the PTO while the choke is still engaged...once the blades start...I gradually push in the choke. No problems.
Incidentally, the day I picked up my 2554, I had the dealer get on it...start it...engage the PTO. It shut off on him three times when engaging the PTO. The forth time, he kept the choke open while engaging the PTO...it finally worked!
Hope this works in your situation.

I would complain to the dealer and engine manufacturer about problem. I am sure there is a cure for this. Needs a little more fuel. You may want to try spark plug change. Also try stepping up to next blend of fuel (ie 89 instead og 87 oct.) Kohler command 21 hp probably has no adjustments for carb. You may want to look at carb for an adjustment with a limiter cap on it. richen it if you can.

Thanks for the choke tip, it has solved the problem.

I have a cub cadet 2550 GT about 8 years old, but under 300 hours. It will start and run 10-30 seconds then dies. I'll park it for 2-3 days, then it will run fine for 1-2 hours, then starts the same thing again.
It has fresh gas, new gas filter. Thoughts?

 

[Bob_Bainbridge]

Try loosening the gas cap when it's stalling. The vent could be plugged causing a vacuum. Other thoughts - plugged or deteriorated fuel line. Could have cracks causing it to suck air. Bad fuel pump.

Regarding 2550 GT dying. No, I run it at full throttle most of the time. It does it after it has warmed up. Will run for 15-20 minutes, then dies. After that, it will start, run 5-30 seconds, then die. After doing that a few times. It will start, run 1-2 seconds, then die. Again, filter is new. Gas is new. As far as dealer goes, it is well out-of-warranty, besides ... the guy (dealer) went out of business. We have an older 2135 that is 100x times BETTER machine than the 2550. Knohler engine in both of them. Could it be air lock? Or ... am I better off to just get a new fuel filter? Thanks

Hi ssellerso,
I have to say it stinks when things aren't running right. I am no mechanic but here is what i would start off doing. I would disconnect the fuel line at the carb to make sure i have good fuel flow. If not check for areas of blockage. Now i would plug the end of the line before attaching it back to the card and some how apply a small amount of pressure to the tank to check for any small pin hole leaks, which may be allowing air to get in. Wouldn't hurt to spray some carb cleaner once you do get it running for the short time it does. With the fuel now days its tough to keep crud from forming inside the carb. Next i would try new plugs but i don't think this is the problem. Can't hurt it. If you are able to give the carb a good cleaning i would do so. Check air filter. Also check oil level as low oil level would cause engine to shut down. Once engine sits oil drains back and allows it to fire back up. I would try these steps and see how you make out. I almost forgot Bob had a good idea about slacking on the fuel cap making sure vent doesn't have a plug. Yes i would also change the fuel filter. Good luck. Let us know how you make out.

Bad gas cap won't show up until engine has run long enough to create a vacuum in gas tank, at which time the tractor could be warmed up. Just a thought. Definitely sounds like fuel starvation for some reason. To prove it you could spray starting fluid into intake when it starts to die and see if it picks up speed. That would eliminate an electrical problem like a bad coil.

I would suspect the vacuum fuel pump..If bad replace with electric fuel pump.

I had a similar problem with a 2284. In my case, I removed the fuel line before the filter and had really limited flow.
I blew compressed air back through and it corrected it.
I assumed there was a screen on the tank outlet that was full of debris.

I probably should have removed and verified, maybe on the next recurrence.

It's been 30 hours or so.

Good Luck,
Curt
