Anyone have any ideas why an impact sprinkler would rotate fine in one

different spots and heights, but the trip pin just sticks on one side.
Any help appreciated!

If it is an actual "pin" that is sticking, and you can disassemble to
that point, get some silicone grease from a hardware store, and
lubricate the pin itself. It feels like anything but lubricant (it's
sticky as all get-out) but it works like a charm, and won't wash off.
