I have been trying to figure out what it means when it says 1st - 540 RPM in the specs for the rear PTO speed. The front PTO listed as engine rpm. OK, It must not mean 1st gear because the PTO spins without it being in any gear at all. ??? What does it mean then? The other thing is Where is the front PTO hidden? I can't seem to locate it. Maybe because I don't know what I'm looking for. I expected to see something like the rear, a splined shaft sticking out in front somewere underneath the machine??? Any answers for these dumb questions?
