Lelyterra 300-33 pto speed?

[ollied]

Got a lelyterra 300-33 3m power harrow but unsure on the pto speed, it’s got the 540 type pto shaft

Try it in both speeds. It'll be pretty obvious

Just because it has has a 6 spline end doesn't mean it should be run at 540rpm.
My Kuhn 1000 rpm machine came with a 6 spline end from new and I have changed my Lely from 21 spline to a 6 spline end to save having to change the tractor stub

Check thickness of shearpins, 9mm for 1000 or 10 mm for 540

It’s got the 9mm pins but I bought some and a new cartridge but apparently they can hold 10mm pins too?

9 mm pins are used in a 1000 rpm machine and 10mm pins are used for a 540 rpm machine but obviously 9mm pins will go into a 10 mm hole if yours will hold 10mm pins it would seem to be a 540 rpm model. Mine has a 7 spline yoke but is 1000 rpm model
