/ Measuring/calculating PTO speed (not PTO speed = Machine speed / implement speed) #41
I notice Amazon sells a digital tach that looks identical to Princess Auto's (all the makes look the same and are probably made by the same Chinese company) for about $25.00I DAGS and searched the forum for PTO speed etc.
So. I have a Hinomoto N279 32HP tractor. Maybe I bought badly as it does not even have its own section here
However.. The N279 has a 4 gear/speed PTO. I know the flail mower I have bought requires a 540 RPM PTO speed. But I do not know for the N279 what PTO speed results from what engine speed in each PTO gear. The Tacho has no indication of PTO speed for each PTO gear.
So how do I measure the PTO speed? I tried writing on a spline with liquid paper. But 540 RPM is what.... 9 per second. Try counting that.
To add to that, the 4 PTO gears do not make sense to me: they do not go 1=slowest 2=a bit faster...etc. They seem to duck and dive, based purely on non-measure obs.
Or do I just wing it, going as high-gear as I can without labouring, running at 1500 RPM of the 200RPM of the N279, and yet getting a decent thrashing?
I understand that the whole thing revolves around also looking at Forward Movement Speed and is all a balancing trick. But I would like to know the figures as a starting point.
