Knife planetary drive mechanism

Production of the planetary knife drive mechanism (MPPN) since 2011 to provide domestic components to organizations for the repair and production of reapers and combined harvesters.

The corresponding unit was developed and then modernized by the design service of the enterprise for installation on combines and reapers, and is not inferior in technical characteristics to imported analogs.

The development was carried out jointly with one of the largest manufacturers of agricultural machinery in the CIS - the company "Gomselmash".

The MPPN passed the procedure for agreeing on technical conditions, finalizing the design at the request of the customer OAO PO Gomselmash, RKUP GSKB for grain and fodder harvesting equipment, passed the bench tests in terms of service life, noise level and heating in comparison with imported analogs.
