Hi,
When I was shopping last year I asked the kubota guy about the two speed rear PTOs I saw on some model...he said that in Japan or elsewhere they must have some implements that run at higher speed [on the back] than we do.
This is a separate issue from the Mid-PTO, which runs at more than 540 rpm [forget the speed at the moment].
Most, if not all, of the rear mounted implements you will find in this country are designed to run at 540 PTO rpm for rated speed of the implement. At least that is my understanding, but it is a big country! /forums/images/graemlins/smile.gif
The PTO will turn at 540 RPM at only one engine speed, since as mentioned in a previous post, there is a gear connection between the engine and the rear PTO output shaft.
In the case of my B2910 this is something like 2,600 engine RPM. In the case of the smaller bx units, it is something like 3,200 RPM. Same thing holds true for other colors.
I think this may have all been said up above...hummm....so why am I saying it again here??? Got me... /forums/images/graemlins/blush.gif
