I'm working on a customer's 21" Toro 'Key-Lectric' Rear Bagging mower with a 3 speed transmission. There's a bare spot on the right rear portion of the mower's frame where I guess the data label would be if it had one. Beyond that, I have no idea what model number, serial number or even in what year this mower was manufactured. In terms of controls, it has a seperate throttle and transmission speed selector (slow, medium and fast). The other two controls, self-propel activation/de-activation and blade engage/disengage cables, are contained in a 'control box' located on the left hand side of the handle. I believe I have fixed the customer's complaint (motor runs but the blade won't engage), but when I removed the control box from the handle to inspect it, the box just fell apart and now I'm attempting to reassemble the box with no technical data to go on. If I had a illustration, I'd have this bad boy back together in a matter of minutes. If anyone has any ideas, I would certainly be grateful!!! Thanks in advance for your help.
