Resolved - drive clutch repair Toro 20055 21" Transmission serial range 260000001 - 260999999

got all the parts I need. Really surprised with as many as was stated get serviced, there were no other members who have done this repair.

25 x 40 = 1000 repairs of this nature just for one shop. Both the local Toro shops had parts, although I had to hit two shops as one had only one clutch left in the pack of 5. That tells me the other 4 went to two mowers.

25 every year for the last forty years

As a follow up. Rebuilt. Goes like a rocket and will leave tire tracks on the concrete if you hold it back while pushing the personal pace lever forwards. The Inner snap ring fell out in pieces on the side that lacked torque. Putting it back together was a challenge because even with the adjuster spring arms hanging so there was no pressure on them, I had to hold one hand on the far wheel, push against the near adjuster block with my side to expose the e-clip groove. While holding that pressure, load the E-clip and squeeze it on with one hand and a pair of pliers. I suspect that the deck is slightly bowed out a little and that puts pressure on the clip that wore it out.
