While mowing, occasionally my Husqvarna 24 hp Kohler will start running rough then want to die. If I disengage PTO it starts to run better and then I continue mowing. Would grass getting stuck under deck cause this? I can't believe grass buildup would bog down a 24hp engine? It's a new mower with less than 100 hrs on it.

I don't believe grass would cause that

Fuel, they run quite lean now days. Have you changed your filter lately?  How about the air cleaner serviced?  Bad gas with water?  Might want to put gas additive like chemtool or sea foam in next tank and in gas for awhile, see if any improvement. I use premium in mine to bypass getting alcohol.

Today's 24hp engines really aren't.
That is the biggest problem
Why do you think that so many people come here to keep the old ones alive?
When I was a kid very few people had "riding lawn mowers"that were over 8HP. If you had a 12Hp that was big and 16 was huge. That NH that I got from you, that I put the 12HP onto handles that48" deck better than a lot of today's"bigger HP" machines do. Deck design and Ralph Nader "You gotta idiot proof everything" types had a huge hand in making today's equipment not as good as what was available 40 years ago.

100 hours on a Kohler Courage is like 1,000 hours on a Kohler Command or 1,500-2,000 hours on an old K series. :rolling:

 

Charging system may be failing due to wear in the plastic Key switch or 1 or more magnets on the flywheel came loose (very common Kohler problem) or grass if it builds up inside the chute will roll into a tight ball under some mowers that have the wide plastic chutes and almost act like a Log.Will almost stall out the blades and mower.

 

Try mowing with your chute tied up a couple inches with a bungie strap if in heavy grass.Drill a small hole in the plastic chute up where the grass comes out about 1 inch from the edge and tie it up or strap it to the tractor.

Yah it's my buddies mower. Don't wanna tell him the bad news lol. Engine seems to run great but every once in awhile it acts up. Almost like it's vapor locking? We have cleaned the hole in the gas cap. Even ran it with the cap loose. It only does it when he's mowing. Maybe I will tie the plastic chute up for him and see how that goes? He says when it does it, he disengages PTO and it comes out of it?

Make sure the gas line isn't laying on the hydro.

My craftsman GT5000 had exhibited some of those symptoms.
Once was a bad fuel filter.
Once, the hydro was heating the gas in the line because it was hanging low.

Really sounds like the grass is bogging down the engine, but it pays to examine all of it.

You might want to make sure the blades are sharp and not just beating the grass to death and clogging up the deck.
