Kye, I thing you would have been focusing on school and your future. I certainly understand the issues, and great to hear from you.
I am no expert here, but the brilliant JP adopted a clever system, whereby the reel could be removed without disturbing the frame.
The issue with the design is with irregular servicing. This mower has sat for a long time.
The drive shaft runs through the length of the reel, and it has become stuck.
In my case, I removed the shaft by protecting the thread with the nut. A wooden block and hammer successfully removed the shaft.
For the folks at home, this was a clever system: - A Villiers freewheel clutch gave the reel free movement for back-lapping. Copper rivets acted as sheer points to prevent transmission damage if the reel hit a solid obstacle.
The issue here is the cross shaft binding on the reel tube. How do you get 3-2 free of 3-1?
