PTO's

My Merc is auto Mark and once the handbrke is on you just press a button on the dash,takes about 5 seconds before it engages doesnt grind but you can actually hear the truck clutching smoothly. If you try to drive the pump will stay on but your rpm is limited to about 1000 .
I wonder if driving with the pto on(just around a yard loading) would cause the clutch servo to expire as mine has recently done :blush:
