Tsubaki cam clutch/freewheel chips in for potato harvester reliability04 March 2021

If you like chips, chances are that you owe your dinner to a potato harvester. Towed behind tractors to automatically harvest potatoes from the soil, these machines are an important tool for ensuring the world’s food security.

When it came to upgrading the clutch on a new model potato harvester, an OEM contacted Tsubaki, a leading designer and manufacturer of cam clutches, to provide a solution. The OEM had experienced reliability issues with a previously utilised clutch and wanted to improve this aspect of the design.

Working closely with the OEM engineering department, Tsubaki engineers tested two different clutches in the field to assess performance. Upon completion of the trials, Tsubaki recommended the MDEU35-TK Cam Clutch. Offering a torque capacity up to 460 Nm, it provided the required performance to suit the application. Furthermore, it was highly reliable during the test period, ideal for the needs of farm equipment.

The OEM fitted the MDEU35-TK to the new model potato harvesters, which proved to be highly robust in the field. This ensured that potato farmers could carry out the harvest in most efficient manner, maximising yield. The cam clutch also contributed to increased equipment uptime, reducing repair costs. Both of these factors conspired to improve productivity and profitability for the farmers using the new harvester.

Tsubaki is a global provider of power transmission components to leading agricultural OEMs. Supported applications include balers, harvesters and seed drills, with all Tsubaki components specifically designed to tackle the shock loading, dust and intermittent operation of farming. Tsubaki engineers can work closely with OEM design and engineering teams to provide a tailored solution for each individual design, as well as structured maintenance support.
