Review: The Locust Solventless Kief Machine

Pin It

Oregonian Stacy Page, the mastermind behind the original Grasshopper Extractor, has done it again and on an industrial scale. His new machine can process hundreds of pounds of kief a day, all without solvents, including water or C02. It does what the original Grasshopper does, but at a much greater volume.

The original Grasshopper has gone through a number of modifications and improvements since he introduced it four years ago. The most recent iteration, the Grasshopper Extractor 4.20, uses liquid C02 instead of dry ice to make a more effective and easily usable machine that can process 20–25 pounds of product each day. With liquid C02 tanks, there’s no need to deal with dry ice, which is highly perishable, and the loading and unloading of the machine is faster. Unfortunately, the cannabis needed to be ground up if in buds, which also takes time.

Page lives in Southern Oregon and has been involved in the cannabis industry for over a dozen years, most recently offering ancillary services like his Grasshopper Extractor processing equipment and previously working in the grow supply industry. His attention to market forces and rapid changes in the industry has led him to create solutions. His original Grasshopper filled a niche. Many companies want kief to make rosin, a heat-pressed extract, and for ethanol extraction. With the boom of the industry nationwide, that niche has grown, and a machine capable of processing larger amounts of cannabis was needed, so Page created the Locust.

The Locust stands more than six feet tall, over six feet long, and weighs about 500 pounds. It is a no-nonsense piece of machinery comprised of three main parts: a grinder, a conveyor, and a separator. It is made of stainless steel for durability and ease of cleaning. It is designed so that you can simply pour the cannabis into a hopper that directs the buds or shake into a powerful grinder, which breaks down the product into a consistency that can be processed. The cannabis exits the grinder to a conveyor (like a giant screw), which transports the product up and drops into the top of the separator unit. There is also an array or ultrasonic generators that provide a solventless method using sound waves instead of C02.  

The Locust can process as much as 10 times the volume of the original Grasshopper Extractor. Most importantly, it does so in a much simpler fashion, which saves a lot of time and labor. The original system, which is still a faster process than that of  other kiefing devices, requires the processor to frequently break the unit down, dump it out, and clean out the screens. The Locust, on the other hand, runs for a couple of hours before its screens need cleaning, and it does not have to be turned off as it operates. The kief is automatically sorted and bagged and the processed leaf material is automatically ejected from the machine. It is a very automated system.

Three grades of product are produced by the machine, which use screens at micron sizes of 74, 100, and 160. The machine comes with anti-static bags to collect the kief, which prevent vapor migration. They are also black on one side to block light when stored. The bags are automatically filled when they are attached to ports on the separator unit while it runs. It will yield between 15 and 20% of the product weight in kief, depending on the quality. See video below.

As with any cannabis processing machinery, it can get clogged and sticky from the process and will need regular cleaning. Page has thought that through and provided a machine that can be broken down and cleaned in as easy a manner as possible. The conveyor is accessible and the separator breaks down into pieces for easy cleaning.

I was able to watch the Locust in action, and it is quite impressive. It will devour the cannabis poured into the hopper as fast as it can be filled, and then automatically process it and fill the bags, with no effort expended by the operator. The first time processed material can easily be added back into the machine for a second run, to make sure all trichomes are removed. It processes multiple pounds in a matter of minutes, and will truly “eat its weight in trim daily” as the company says.

The Locust and Grasshopper are both assembled in Medford, Oregon, by Page’s company, Enovators LLC,  an Oregon company. The Grasshopper Extractor 4.20 is priced at$ 5,900 and can be shipped anywhere in the continental United States. The Locust is priced at $59,500 which includes delivery, set-up, and training anywhere in the U.S. Visit the website at for more information and videos on these products.
