I have a toro zero turn with a 25hp kohler that stalls when i engage the deck. i have to drive about 5mph and engage and it will run.
After the first statup everything works fine. you can turn the deck off and on without any problems.
only chokes the engine on the first startup for the day.
Could it be running lean?
Sensitivity of govener spring?
Thanks

Are you letting the motor warm-up a little before the 1st attempt at kicking on the pto. Most of the Kohlers do not run well (atleast with any power) until they've warmed up and the choke is off. I usually let mine run about 3-5 minutes before getting started. I have a couple 18HP Kohler's on Cub-Cadets that are temperamental at start-up but run well later. One of them must also be run for up to a couple of minutes to cool-down or it will diesel when turning off the key and backfire. ....

I agree that not letting it warm up enough is the problem.
