I have a 52" Toro Commercial walk-behind mower, model 30297 with a Kawasaki engine. The blades will engage just fine, but then when I push the control bars forward to move, they disengage. I can sometimes manage a very slow movement forward with them on, but any amount of strain will kick them off. I have replaced the PTO switch, fuses are fine, and just replaced the ignition switch as well. Any ideas will be helpful, thanks!

There is a operator presence switch on the bar your pushing it needs to be replaced.

It wasn't the operator switch, anyone have any other ideas?

Check the op switch whatever is suppose to hold it down isn't doing its job.
