Gras-Master from scenery specialist NOCH is a tool that allows modelers to model the most realistic grass practical. From the early days of scenery, modelers have used many methods to represent grass - saw dust, rope, brush bristles, ground foam and ground up natural material. Then came static grass. But even it tended to lie flat. Then someone figured out how to make a charged field to stand the grass fibers on end. And then NOCH introduced the Gras-Master.

Gras-Master generates an electrostatic field to that makes synthetic grass fibers stand upright. How?
    The electrical circuit within the Gras-Master converts the 9V battery current into a stable high voltage reaching 15,000 V DC. The coating at the bottom of the white container is a special material that creates a negative pole carried by the grass fibres. The positive pole travels through the cable from the top of the device and releases through the alligator clip. As the fibres exit the sieve they are pulled mid-air through an electrical field allowing the grass to land in a vertical position on the surface area.

This Gras-Master, item 60131, is the original model, recently supplanted by item 60135, Gras-Master 2.0. The new model generates a higher charge, reaching 20,000 V DC. While this original Gras-Master is no longer in the NOCH catalogue, this review of the original Gras-Master demonstrates what Gras-Master 2.0 can do, with that greater charge. And a recent search shows many Gras-Master, item 60131, available for sale.

Gras-Master is a plastic reservoir on a metal handle. A battery inside the handle energizes the electrostatic field. The tool is factory assembled.

NOCH packs the tool in a cardstock carton with the following contents:
    Alligator Clip with Cable (pre-attached)
    Small Sieve
    Large Sieve
    Nozzle with two Sieves
    9 Volt Alkaline Battery (pre-installed)
    1 x Bag of NOCH Static Grass Summer Meadow( Item No. 08310)

A multilingual instruction sheet is proved, too. You can see it via the link Click here for additional images for this review, below.

I made a video demonstrating the Gras-Master, showing how I applied NOCH Graskleber (Grass glue, item 61130), to a pair of diorama bases, filled the cup with static grass, screwed on a sieve, and charged the tool and applied grass. It turns out I mistakenly used a nozzle sieve inside the Small Sieve, but that made little difference other than I had to shake and agitate Gras-Master more than necessary.

The tool is simple and quick to employ. There really are not any drawbacks or problems with a Gras-Master. It made the static grass land vertically in the glue.

Gras-Master works great and I can only conclude that a Gras-Master 2.0 will work better. Modelers who desire highly authentic and realistic grass on their layouts and dioramas should seriously consider acquiring a Gras-Master. Vertical fibers of static grass will be the ultimate grass effect until somebody figures out how to grow scale grasses.

I do not have any meaningful complaints about NOCH's Gras-Master.

Gras-Master is a highly effective tool for modelers to cultivate very realistic grass. Recommended.

I'm a professional pilot with a degree in art. My first model was an AMT semi dump truck. Then Monogram's Lunar Lander right after the lunar landing. Next, Revell's 1/32 Bf-109G...cried havoc and released the dogs of modeling! My interests--if built before 1900, or after 1955, then I proba...

That's the gadget I used for my dios, so if you dig my grass er man, I highly recommend it. If there are any drawbacks I'd say it's not exactly "easy" to use, it takes some practice and patience but after that the results are...upstanding. I bought mine 2nd-hand from a guy in Austria years ago (probably the Mk 1 version, I've since passed it on to a friend who's doing a 15 x 6 metre railroad capable of running 12 trains at once - he's Gras-Mastered about 20 square metres of landscape HO scale & it looks superb)but it wasn't cheap,although cheaper than Retail - so shop around.

There are so many tutorials for DIY applicators that cost $25 and less. I made one - it ain't pretty but it works! LINK
