<p>A rotary sprinkler (10) and sled base (20). The sled base (20) has a main body (22) with a pair of wings (32) pivotally connected thereto at opposed sides. The wings (32) permit compact storage when folded in and provide a wider footprint when folded out to make the sprinkler more stable. The sprinkler head (40) has a water channel (24) which permits the jets to be lower to the ground for increased sprinkler stability. The sprinkler (10) has a plurality of different sized vertical jets (64) to achieve a more uniform water distribution, the top jet spraying further from the sprinkler, the bottom jet spraying the closest. The sprinkler (10) has deflection means (90). The deflector (92) may be manually adjustable to fix the maximum spray distance or the deflector (92) may be connected to a cam follower (98) which follows a deformable circular 'roller coaster' cam surface (86) to alter the maximum spray distance as the sprinkler (10) rotates. The deflector assembly (90) may also include means for reducing water flow of the jets (64).</p> |
