FarmTRX is proud to build and assemble our Yield Monitors in a North-American local farming community – Elbow, Saskatchewan. Our manufacturing partner employs local workers, and produces an incredibly high quality product that we are confident in standing behind. All FarmTRX hardware is backed by a 2 year warranty.

In 2015 Farmer and Technologist Perry Casson built the first FarmTRX prototype in Medstead SK. He had begun variable rate trials with Cavalier Agrow, and wanted a way to measure the outcomes of his trials. Soon after building his prototype he garnered interest from local farmers and agronomists who were looking for exactly what he had invented – a Yield Monitor that was affordable, easy to install, and most importantly – easy to use. 
Since that time, the technology and hardware components have evolved significantly, and collaborating with Troo Corp now provides a powerful web mapping platform. 

FarmTRX Yield Monitor

Designed By Farmers & Locally Made In a North American Farming Community.

The FarmTRX Yield Monitor is designed for all types of farmers, whether you’re technically inclined or not. It retrofits to nearly any make/model/age combine in just a few hours and uses your smartphone or tablet instead of an expensive dedicated display. It was designed to be easy to use – so you can focus on farming.

The FarmTRX Mobile App will display live, average, and cumulative harvest data on your smartphone or tablet – as well as allow you to wirelessly upload your yield data. You can upload at the end of the day, the end of the week, or the end of harvest season – whenever is convenient for you. And if you forget to bring the tablet, don’t worry – your yield data gets recorded no matter what.

Harvest season can be hectic, so we made setup easy and fast. Simply select your header & crop type and you’re good to go. Calibration is simple – just harvest a known amount, such as a full hopper or by using weigh wagons, and enter the actual amount into the app. And if things get busy and you don’t calibrate – it’s easy to fix things later online when you have the time.
