hey guys, working on a project and im looking for a few gears for the pto. i have a 180 that im wanting to convert to the 2 speed but i want to find early 180 2 speed pto or early 190 1000 rpm pto gears. the idler gear part number is 70243093. the clutched dropbox gear numbers i have are either 70244485, 70255315 or 70255314. the manual pto box gear number is 70243094. i have a hydro pto now but would convert to manual if all i can find is that manual pto gear.

The idler gear on the early 180 and 190 is a 32 tooth rather than the 29 tooth of the later tractors, but i dont know the tooth count on the dropbox gear. But this is a project that i want more pto speed for and not wanting to rev the engine any higher. im planning to call Mark Heitman soon for the parts but i figured i would ask you guys first. Thanks very much!
