I have a 17hp Sears rider. I don't know the model number but hopefully the attached pictures will give you enough info to give me advice.
I was having problems getting the motor running so we pulled the transmission pin out and disengaged the transmission(see picture) so we could move it around. (hopefully I am using the correct terminology) I don't know if this has anything to do with my problem, but we left it in the disengaged position for over a week and when we got the motor running (so happy) I changed the location of the pin so it was no longer diengaged and found that the transmission wouldn't work (so unhappy). The mower wouldn't move forward or backward. I can hear a very slight "rubbing" sound when in forward, but nothing in reverse. I don't understand transmissions AT ALL, but am somewhat handy with good instruction and would love to learn. What are my options? What do I need to check? What information would I need to give you so you can make a for informed diagnosis?
Any help would be great and I would be grateful.
