Two different issues causing this post. 1st issue: Tried ordering a service manual for the GC2310 from Jack's Small Engine and they allowed they are no longer available from their supplier, next I'll try a dealer. Second issue: Since no manual: I can not confirm that the PTO guard seems to be installed incorrectly (bought the tractor used with 112 hours now has 275). The front mounting bolts appear to be correctly installed see picture number one of left side allowing the guard to pivot up and down. The back bolt does not attach to or through anything and it blocks the PTO guard from going down and over the PTO. In this configuration the guard is blocking the 3 point lift arms from depressing completely. See pictures 2, 3 and 4. Anyone have pictures of how is should be? How far down should the lower link assembly be able to go?
