Unreliable impact sprinklers

[Donald R Smith]

Every had trouble with these things! Knockers or impact sprinklers
purchased from the local hardware that will not keep working. Or worse
still, fail the minute you look away. Maybe even work well for a week then
are discovered squirting volumes of water in one direction only.
Is there a lubricant suitable to ease these monsters? Or is the solution
merely to remove the offender and after placing it carefully on the ground,
hit it with a large hammer?

Larger the hammer the better. Had the same problem. In the end bit the
bullet and bought "gear drives". 3X more expensive. Thousand times better.
Never had a problem since (12 months)

I have an elderly rotary sprinkler, which periodically starts to
chatter and rotate slowly, or not rotate at all. I shake out the
water, and squirt a few drops of lawnmower oil into the bearing, and
it is good for another few years. May work on yours, if you can find
the right spot to oil.
