Marijuana Trimming Machine



The industry is growing - and so are we

Shearline | Cannabis Processing Machine

The team at Shearline has designed and manufactured marijuana wet and dry trimming machines for over twenty years now. In fact, the first cannabis processing and trimming machine was introduced to the world in 1997 by Ryan Hall, who is still hard at work in the company. Since then we have continued to come up with improvements and innovative concepts that are in use around the world in the hemp and cannabis industry.

As cannabis and hemp production is becoming legalized and regulated across the world, it has provided a new and welcome challenge to all aspects of its production and processing.

At Shearline, we care about the health of ultimate consumers and your reputation. We work to ensure that our trimming machines for marijuana and hemp are compliant with health and other government regulations. This is why we invest heavily in continuous research into compliance requirements that government agencies around the globe are implementing or propose to implement to protect the consumer.

Our unique geometry between the blade edge and the cutting reel has proved to have a scalpel quality cut but without any metal on metal contact. This ensures there are no fine metal particles in the flower or trim, and as a result, none in the consumer’s lungs or body!

All moving components are placed in stainless steel solid lube bearings. No grease or oil can contaminate the product. They are maintenance free and can withstand the high-pressure hot water washing systems needed to meet the sanitary protocols now required.

Another huge benefit of the above improvements and electroless nickel plating is the slippery, easy to clean nature of these materials. You will not believe how easily it resists the sticky resin that cannabis is famous for.

Our brushes are made from food grade nylon and stainless steel, our drive rings are made from food grade urethane, while the bearings are stainless steel with solid oil food grade polymer lubricant.

Our hemp and marijuana processing machine is constructed from materials classified as food grade, such as 304 or 316 electropolished stainless steel, clear hard anodized aluminium, D2 hardened steel blades and our amazing highly polished, precision balanced, perfectly sharpened cutting reels. Furthermore, these are plated with an extra thick layer of food grade electroless nickel. This ensures not only a lifetime of corrosion free operation but also a razor-sharp edge that will last for years!

All of the above and our meticulous attention to detail means you don’t have to worry about inspections or down-time when you have equipment made by Shearline!

Key Innovations

The Magnetic Blade Holding System

Durable, easy-to-clean blades that are gentle on the product while ensuring an extremely clean, tight cut.

The magnetic blade holding system not only allows us to use a much harder steel than the lawn mower blades our competitors use, but it also enables the operator to periodically remove and clean the underside of the blade in less than five minutes! This is especially critical to maintaining a clean cut throughout a days operation.

As a result of processing the buds, the machine builds up with resin (particularly under the blade), which heats up, hardens, and causes the cutting reel to force the blade up. Like a fine pair of scissors, if the gap between the blades is loosened even a small amount, the clean cutting action is turned to tearing and pulling of the leaf! Consequently, the finished product is rough and ugly when dried. Both of Shearline’s machines have been designed to eliminate this problem!

The Patented
Drive System

Fewer parts, one motor, unequaled results.

The drum style trimmers undoubtedly offer the gentlest, fastest, and tightest method of removing the excess leaf from high quality buds. However, the old style required two motors and a large number of parts to operate. The Shearline Original and Shearline 2.0 operate with our patented drive system using one motor, greatly reducing the parts required and the amount of things to break or wear out!

The Highest
Assembly Standards

Our staff of specialists are here to work with you through setup, maintenance, and troubleshooting.

Finally, no matter how well parts are made, they must be inspected, and assembled in a precise, meticulous manner if they are to operate as designed and last for a lifetime. As a rule, we hold ourselves to the highest standards in this! Hence, should anything go wrong, rather our fault or the operators, we will do whatever is necessary to get you back and running as fast as possible! You can count on us!
