The Adjustable Gear Drive Sprinkler (MGDR) is the go-to rotary sprinkler for homeowners, gardeners, and landscapers who need reliable, uniform coverage over large areas — without the noise. Its internal gear drive mechanism delivers a smooth, steady rotation that is virtually silent during operation, making it ideal for nighttime watering when noise is a concern. Whether you're irrigating a wide lawn, a large garden bed, or a sprawling landscaped area, this sprinkler provides even, consistent water distribution from a 10- to 35-foot radius (at 50 PSI) with an arc adjustable from 30° to a full 360°.
Unlike impact sprinklers that click and clatter, the MGDR's gear drive action runs quietly and dependably cycle after cycle. The easy slide distance control lets you dial in the exact radius you need without tools, and the removable filter screen keeps debris from clogging the nozzle — extending the life of the sprinkler and reducing maintenance headaches. It connects via a 1/2" male pipe thread (MPT) inlet, making it straightforward to install on standard risers, metal stakes, or flexible swing joints. It is sold as a sprinkler head only; pair it with the 8" Metal Stake (MGDSM) for above-ground use in garden beds and landscapes.
If you're building out a larger landscape irrigation system, DripWorks carries everything you need — from irrigation timers and controllers to zone valves and pressure regulators. Need a different type of rotary sprinkler? Browse our full selection of rotary sprinklers and yard sprinklers.

Why is this called a "whisper quiet" sprinkler?
Most rotary sprinklers use an impact mechanism that creates a repetitive clicking sound during operation. The MGDR uses an internal gear drive instead, which eliminates that noise entirely. The result is smooth, near-silent rotation — making it ideal for residential use, nighttime watering schedules, or any setting where noise is a concern.
What is the coverage radius of this sprinkler?
The MGDR throws water from 10 to 30 feet at 20 PSI and from 10 to 35 feet at 50 PSI. The easy slide distance control lets you set the exact radius you need. For best results, space heads at or under the maximum radius for your operating pressure to achieve head-to-head coverage.
What inlet size does this sprinkler use?
It uses a 1/2" Male Pipe Thread (MPT) inlet. It connects to standard 1/2" female-threaded risers, swing joints, or the 8" Metal Stake (MGDSM) sold separately. If your system uses a different thread or pipe size, DripWorks carries a wide range of fittings to make the transition.
Can I adjust the arc to cover just part of a circle?
Yes. The arc is fully adjustable from 30° to 360°, so you can configure it for tight corner coverage, a narrow strip, or a full-circle pattern. This makes it very versatile for irregularly shaped lawn areas, garden beds along fences, or any non-rectangular landscape.
How do I adjust the throw distance?
The MGDR features an easy slide distance control that allows tool-free radius adjustment. Simply slide the control to reduce or increase the throw. There is no need for a special wrench or screwdriver for basic distance adjustments.
Does this sprinkler include a filter screen?
Yes. It includes a removable filter screen that catches sand, debris, and particles before they reach the nozzle. The screen can be pulled out, rinsed clean, and reinstalled — no special tools required. Regular cleaning of the screen (especially in areas with sandy or hard water) will extend the life of the sprinkler significantly.
What mounting options are compatible with this sprinkler?
The MGDR is designed to be used above ground. The most common mounting option is the 8" Metal Stake (MGDSM), available separately, which pushes into the ground and provides a stable platform. It can also be installed on a standard 1/2" threaded riser or a swing joint assembly. DripWorks carries stakes and risers compatible with this sprinkler.
What pressure range works best with this sprinkler?
Performance data is documented at 20 PSI and 50 PSI. Most residential water supplies fall within this range. If your supply pressure is significantly higher than 50 PSI, we recommend installing a pressure regulator upstream to protect the sprinkler and ensure uniform distribution.
Can I automate this sprinkler with a timer?
Absolutely. The MGDR connects to any standard irrigation system that operates solenoid valves. Pair it with a battery or AC-powered timer and a zone valve for a fully automated watering schedule.
