Fortunately they were smart enough to make the plate stay on the tractor for either setting. As I don't yet have any 3pt implements, this is a non issue for me.......yet.
but the engine will not be operating at it's optimum torque and horsepower so unless it is lightly loaded a tiller or rotary cutter or whatever would lug the engine. I have never seen an implement which needs the higher speed but I am sure there must be some.

Must be kind of like that 78 rpm setting on the old record player. lol Actually I used to have an L245 with 3 speed pto. I would use the higher pto gears for running something like my cement mixer which needed the speed but required absolutely no power, I mean you couldn't even detect a load on the motor when it was running, so I could run it at an idle in the highest gear. I would also use the higher speed for making a second pass with the tiller to chew things up a little more. My neighbor (B7500) has a log splitter with a pto pump so he uses his higher pto gear for that. But I am really unaware of any pto powered implements that specify 960 rpm.
I presume it's a safety issue. Mine came with the plate in the "out of the way" position, and I've never really given it a lot of thought. I have considered running the mower with the rear PTO in the "high speed" mode, but with the engine running at lower speed. This would seem to work well when I'm only slashing grass, as there seems to be a lot of excess power when running at regular PTO speed.
I just ordered a PTO chipper that will run on the 540 PTO speed, but it is recommended that it run between 800 to 1000. As a result, I will probably run the rear PTO high speed when I run the chipper.
