Bought this 1490 where it sat on a dealer lot. Pto clutch is stuck as I get some grinding when engaging the pto lever behind the seat with the pto clutch lever locked up and disengaged. Did the test where you engage pto clutch ratchet lever into locked position and try to turn pto with a pipe wrench and it's damn near impossible to turn without standing on the wrench. I have already tried adjusting the cables per the IT manual to no avail. I get movement of the cables and they seem to apply good force as it takes some pull to get it locked out. Attached is a picture of the pto lever. I will try this weekend putting my mower on and working it hard with the clutch lever locked up as suggested by Adirondack Case Guy. Any other known remedies I can try or anyone know how to maybe spray some brake cleaner in there, is there any access point?
