Short recap. Friend"s D17 went kaput some time back and we have been waiting to get a shed built to work on it. It"s sitting where it quit, with these reported symptoms:
1) starts fine and sounds good (with clutch in)
2) let clutch out and tractor dies, no horrible noises
3) with clutch in and transmission in nuetral, tractor will roll and can be pulled. Let clutch out, wheels lock up.
I am pretty green and was going down the path of the transmission being stuck in two gears causing the bind and the engine to die. However, after studying I&T AC-13 and looking at Dan"s awesome pics, it would seem if the tractor will roll, the pinion and gears must be moving freely in the tranny and thus be in Nuetral. If stuck in two gears, it appears that would lock the pinion shaft and therefore the rearend making it impossible to roll.
If I am correct (and may not be), it would seem with the transmission clutch in and the tranny in nuetral, the problem area is isolated to the "power director" and/or trasmission input shaft.
Is my deduction reasonable and if so, what is the best starting point? We have a manual (AC-201) on the way, I just like to give myself some time to ponder and better understand the possible problems. TIA for any input.
