Fully Enclosed Flail Mower Bearings Keep Contaminants Out

Contaminants are bad for bearings. So why leave them exposed like all the others?

As most of you know, we’ve been doing this flail mower thing for quite a while.  Vrisimo flail mowers were designed in the 1960’s, and we’ve been building them here at Valley Tool and Manufacturing since the mid-80’s.  That’s 30-ish years of experience just here at our facility in Hughson.  In case you’re wondering, yes, we’ve just about seen it all.  If you don’t believe me, check out the picture below of one of our mowers being dunked underwater.

Flail mowers, just like most agricultural equipment, endure some pretty harsh environments.
They’re expected to mow thousands of acres of orchards each year, ranging from mud in the Northwest to the sands of Bakersfield, California.

When you consider that the main bearings for these mowers have to survive those kinds of conditions, it’s astounding that they’ve been left out in the open for this long.  It seems sales-pitchy to say it like this, but we’ve finally come up with a solution, and we’re not shy about sharing the details on how.

The secret is simple, really.  We’ve developed a fully-enclosed, piloted housing that actually sits inside the main drum of the mower.  The result?  Simply put, it’s a maze, and it’s designed to trick dust, dirt, water, tree rope, irrigation tape, and just about anything else into never making it to the “center” (aka, the seal).
