I know I must take a toll on the wet and dry clutches of my GST L39 when plowing snow, forward and reverse at load and up to 2200 RPM, over and over again and again.
Respectfully I am not sure that is the case. I have a 11,000 pound John Deere 350D bulldozer with hydraulic reverser and it is 30 years old. A bulldozer by design is to run at full throttle, and shuttle back and forth without stopping, it even says so numerous times in the service manual. My bulldozer has its original reverser clutches and so far has only needed a hydraulic oil filter changed on it and runs perfectly fine.
The two most detrimental factors for hydraulic clutches in my opinion are dirty oil and heat. The clutches themselves are designed to take the enormous load.

Myself, and I know this happens on a farm, I think the hired hand is bored and needed something to discuss. It is all in good fun, but I think the clutch wear is being over analyzed. The only pto attachment I throttle down before shut down is my pto generator, BUT even then I am not sure with a PTO over-running clutch on it, that it really matters.
