Impact sprinkler

The original horizontal action impact drive sprinkler was invented in 1933 and patented in 1935 by Glendora, California[1] citrus grower Orton Englehart.

The uninterrupted flow path of impact heads makes them less vulnerable to damage and clogging by dirt and sand in the water.

The impact sprinkler's long spray radius and uniform water distribution re-creates the effect of natural rainfall, this is what makes it perfect for many irrigation tasks.

Although these variants provide regular convenience, malfunctioning sprinkler heads that fail to recede may become damaged by an inattentive landscaper mowing over them.

Although largely replaced by gear-driven "rotor heads" by the 1990s, impact sprinklers still have many advantages, including uniformity of coverage, sand and grit resistance, and operation at lower water pressures.
