Hi Friends,
I have a new project, I bought a Toro Z Master zero turn, it has a Kohler 725cc engine with a blown head gasket and a bent push rod.

The mower has 2676 hours on it and has been treated a little rough but the inside of the engine is very clean and cylinder walls look fine.

My questions are to you guys that know small engines (I don't). Should I have the head surfaced, or do they even do that to small engines? What would cause it to bend a push rod. And what else should I do to this engine while I have it apart?

I know a lot about car engines but with small engines I am a rookie, any help and advice would be great. Thanks:thumbsup::thumbsup:
 
Shave the head? NO. Bent push rod, probably caused by valve clearance be too wide, rocker arm jumped. Post the model numbers and I'll find you a service manual.
 
Model-CH25S
Family-SKH725UIG-can't read the last digit
Spec # 68606
Displacement (cc) 725
Serial # can't read

Is this a 25 HP?

Thanks
