I understand
what was the point earlier when we saw that the rear pto is spinning but the rear tires won’t spin?
I think demonstrating that something in the transmission was working - since the PTO drive is part of the transmission.
If the PTO is working then at least some of the transmission is working. If the engine doesn't sound loaded when in gear, then seems like the HST isn't even trying to drive.
Possible problems are (from NIW - just summarising):
- HST pedal not connected properly, so it's not telling the transmission to drive
- Range selector - if the range selector is in neutral then pushing the pedal will do nothing
No doubt there are other potential problems (more expensive ones) if the pedal is working but the HST not giving drive - it could be the HST pump or something. But better to start with inexpensive potential problems.
Another potential diagnosis is to lift the drive wheels off the ground, and press the HST pedal. See if the wheels turn at all. Also try turning the wheels by hand when in neutral on the range selector. That would eliminate seized wheels, and also tell us whether the HST is trying to drive at all (maybe with the wheels in the air they will turn a little). But from the video it doesn't seem like there's any drive at all - no change in engine speed, not even a little rocking - so it's like the range selector is still in neutral.
I noticed to start it you had to put the range selector into neutral (I think that was the cutout at the start where you shifted a lever before it would start). I think I saw you put it back into gear......but surely that would cut the engine? Perhaps that range selector isn't working properly?
