This year’s Potato shows started with the Montana Seed Seminar and the Alberta Potato Trade Show in November and then to the Potato Expo in Aurora, Colorado and then the shows at Michigan, Idaho, Washington, Manitoba, Wisconsin and North Dakota/Minnesota and Colorado. Attendance at the Mayo display is always excellent and we enjoy connecting with our customers.  See a list of potato shows on the events page.




Mayo has delivered a wide range of storage and transloading equipment.  This includes Bin Pilers, Conveyor Systems with Telescoping and Portable Connecting Conveyors, Surge Hoppers and Evenflows and Unloading Conveyors with Stingers.  Mayo Conveying and Piling equipment is built to handle high volume with gentle handling and the best durability.  Outstanding service along with quality is what Mayo is known for.

We are growing!


We have added several thousand square feet onto our facility in Idaho Falls for parts and service area.  Our Idaho location services customers and dealers in Idaho, Montana, Washington and Oregon as well as BC and Alberta.



Besides potatoes, Mayo designs and builds equipment for a variety of fruit and vegetables, including carrots, onions, sweet potatoes and apples, all pictured below.  This equipment can be similar to our regular lines, altered for the product or designed specifically for the product.






Mayo Building Expansion 

Our most recent expansion has been completed, providing substantial more space for machine assembly and staging.






A packing shed expansion project.  Mayo equipment added included washers, sizers, flumes, debris removal and integration with a Mayo polisher and Tomra optical sorters.  The expansion used all stainless steel equipment to increase volume and accuracy and reduce labor.






A chipping potato project in the Northwest.  This system includes an intake flume for debris removal and presoak.  The chip potatoes are then thoroughly cleaned with a brush wash and high pressure spray.  Drying is done by a felt dryer.  Next is a roller table for sorting and then into a Mayo evenflow before bulk and tote bag shipping.  The system is efficient and effective.  The water system was designed for above floor operation using a Mayo water reclaim tank which uses a two step water cleaning process for reusing water while introducing fresh water.

Fresh Crop Project

A project completed in the Southeast.  This line starts with unloading bulk semi trailers from the field and incorporates washing, sorting, sizing and pilers for loading out.  The design includes Mayo scale conveyors and integrates specialty equipment from other manufacturers.
