A:  The 42SA rotors have a spray distance of 26 to 38 feet, depending on the water flow and pressure. These rotary sprinklers have a spray distance of 13 to 18 feet, so you want to make sure there is enough grass coverage between the sprays. You want to avoid dead spots, and these sprays are designed for head-to-head coverage, which means the end of one spray should just touch the beginning of the next spray. There is another rotary sprinkler that sprays 17 to 24 feet, which could be closer in distance to the 42SA, called 22SAPROPR, Store SKU #1005637008. You also want to be aware that 42SA rotors have a 3/4" connection size, and the rotary sprinklers have a 1/2" size, so you would have to purchase connections that will step down the pipe size.

A:  It is the radius, which is the distance the water will travel from the sprinkler.

A:  I believe it is the "throw distance". You adjust the sprinkler head to set the distance you need - from the sprinkler head.

A:  That's the radius of the circle (or arc) created by the water pattern. It's a circle 13-18' radius or 26-36' in diameter.

A:  There is an distance adjustment dial below the head.

A:  Yes it does. I had to goggle it to make sure but didn't know that was what it was called.

A:  Yes, it comes with an R-VAN18 adjustable nozzle.
