Well my first real post on the forum, here goes.
I have a Kohler Command Pro 27 (according to the carb cover anyway) that has a loss of power at speed. I know, not a another one. Lol. This is a CH740-0037 Morridge engine with serial number 3631007811 and a build date of 11/6/2006. This is in a 2007 Grasshopper 727K2 with a manual height (want Powerfold) adjust 3461 deck. The engine wants to die when the deck is engaged. Sometimes it does die. Also it is a little hard starting. Now usually I can throw whatever I want at this machine to mow and it takes it all with no issues. The last couple of mows this year was a little rough since it would bog down and really struggle is spots where it would just chew the grass up and spit it out.
Here's the list of things that I have looked through or changed out trying to chase this issue down. I have already changed out the head gaskets about 400 hours or so ago. The engine has about 880 or so on it now. I have changed out the fuel filter with a Kohler one. I have changed the fuel pump, rebuilt and cleaned the carb, replaced the coils. I even checked everything on the deck and it moves with relative ease. I have replaced all the drive pulley bearings for the hydros. I have even changed the PTO clutch thinking it was wearing out. That turned out to be true but not the issue.
I haven't checked compression or fuel solenoid yet. I plan on doing that this afternoon. I'm starting to run out of ideas here. If there is anything else that I could check or send me in the right direction it would be greatly appreciated. This machine may become my snow removal machine so I want this running great. That is a discussion for another thread to be started soon. :laughing:
Thanks for any advice in this!!
