Toro Blade Brake

I have a Toro model 20622 walk behind mower, serial 6031575, and I am having issues reassembling the brake plate assembly. I'm not sure I have the spring on the lever that secures the blade assembly to the body in the right position. The upper spring tang sits against a stop on the lever, but where does the lower spring tang reside?

Does anyone have a better diagram than the one on partstree here? Parts and Diagrams for Toro Consumer 20624C, Lawnmower, 1988 (SN 8000001-8999999)

Thanks for any help.

The way I have it assembled now, the blade brake assembly does not have enough spring tension to release fully from the disc drum, so the blade does not turn in the engaged position.


Anyone at all have experience in troubleshooting, or can describe the proper spring tang location on the upper and lower spring tangs. I'm confident the lower spring is positioned correctly, but I'm unsure if the upper spring is positioned correctly. Is this spring under tension against both an upper and lower tang stop?

I'd appreciate any input.

Thanks.

It's been a long time since I've worked on that model Toro so I don't recall the precise instructions you're after. All I can say is, take a fresh look at it and reason it out keeping in mind the direction the spring NEEDS to rotate to obtain tension and using that to the advantage. Also, pay attention to the spring tails, they typically will give you and indication as to which way the spring must be hooked up. And, don't forget to look at paint wear for signs of proper hookup.

puey61, thanks, I figured it out. Took the thing apart last fall, and couldn't find the replacement part, and finally found a source this spring, so it was a while since I disassembled it.

The upper spring on the top side of the deck was the one giving me issues. There is a boss on the top side of the deck for the lower tang, and the upper spring tang rests against a stop on the actuating lever.

One of the first things I checked was for paint wear at suspected tang stops. Unfortunately, none of the paint had abraded.

Thanks for responding.
