Small Engines (Lawn Mowers, etc.)/toro blade brake clutch

Question
Working on a Toro GTS 20624 self propelled push mower.  The blade is slow to engage and then when you mow if the grass has any thickness, the blade slows way down almost like the blade brake is engaging.  Also the toro is noted for the "bang" when the brake engages and I am not hearing that.  What should I be looking for to check in this situation?  Thanks

Have you downloaded the service manual from the URL below?

The most common problem we find are wore belts or old cables that stop properly working...they get dirty and rusty and need to be replaced every now and then.

Have you checked the belt and engagement cable?

Experience

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
