my century 3045 has 540 and 1000. The 1000 comes in very handy with my snowblower and when I'm using my cutter when the grass isn't real high. I don't have to run the engine so hard. You just have to remember NOT to rev it up. Also with the rpms down it is slower geared so it gives you more versatility with speeds. I have a 5ft snowblower and I run the engine at 1500 rpms. It really throws the snow smooth and I've never plugged it up. That is about 650 pto rpms. When I run the cutter I run it at 1350 and that keeps the pto rpms about 540. I've even used it with my tiller when I wanted a really SLOW speed. In low range first gear at 1300 rpms and you are just moving.

Frank - which new models have you noticed with 2 speed pto?

my b1550 has a two speed rear PTO. I've never really used the higher speed yet myself. I thought I might try it with the bush hog grinding up black berry vines.

The B-7500 has it and I assume the new B-7510 will also. I have never used mine.

My B6100E has a three speed PTO. 540 rpm is the lowest but I don't remember or use the other two. This was one of the earliest CUTs. I read somewhere that in Japan they had equipment that used the other speeds. This tractor has a mechanical lockout so you cannot use other than the 540 by accident.

My 1994 B7100 had the 2spd PTO. The low side (540) would run all 540rpm rear implements and the high side (960) would engage the mid PTO and 960 rear PTO at the same time. I only used the high side for the MMM.

I just got my B7610 this past Saturday and it has the 540 / 960 rear PTO also. When I was "test driving it" at the dealer - I asked what benefit it offered: he said that it's used for running the vacuum / grass catcher. (but I don't have one /forums/images/graemlins/frown.gif ... yet!)

Makes sense - it does activate in parallel to the mid-PTO (2500 rpm).

Cheers,

Dan

i beleive the b7610 has it and probably some others, just curious how u could run an implement theat wes designed for 540 rpn at 960 rpm and not do harm to it? i am as usual /forums/images/graemlins/confused.gif

that! i did not know and nowhere on kubotas site does it say that, just the rear pto is 2 speed.

regarding running implements at higher speeds, it is not a good idea. I think folks on this string are running low engine RPMs to keep the implement spinning near 540. I recently bought a tractor with a 3 spd PTO, and the owner showed me the high speed with a tiller attached (!) I think it would self destruct if you tried to till dirt at 1000 rpm..... /forums/images/graemlins/shocked.gif

The Owners Manual for my B7610 does state that you should not use the 960 rmp PTO speed for implements designed for 540 rpm.

The B7500 that I looked at last Friday, has two positions on the pto lever, one is for the rear 540 pto, the other position is for the front pto for the mmm.

Some of the grey market tillers are designed to operate at 1000 RPM. My Yanmar had 3 speeds. At 1000 RPM, that tiller worked wonders on this clay.
