I would buy the Hunter ATR impact replacement kits,,,,,you simply buy a maxi paw wrentch and pull out and unscrew the impact heads out of the canister and the PGP (number one selling rotor) in this kit, screws right into the canister, so there is no digging involved. This reaplaces the Impact with a gear drive, which will last for years, and op[erate quietly!! Hunter PGP-ATR kit........(one for each impact) as far as the sprays, you dont have another choice...i would move the risers behind trees, and put a pop-up on top, so it pop-up above the trees and waters.......They also have Pop-up Risers, that will sit above ground (behind or in a shrub) and pop-up further nd water!
