Abstract
A slide assembly for use in supporting and guiding a reciprocating push rod or the like so as to enable reciprocating movement of the push rod while undergoing translation transverse to its longitudinal direction. The slide assembly includes a tubular slide guide which receives a slide tube therethrough having a slide housing supported transversely on an end of the slide tube externally of the slide guide, the slide housing having an axial passage to receive the reciprocating rod. TEFLON bearings are interposed between the slide housing and the reciprocating rod and between the slide guide and the slide tube, and lubricating fluid felts are supported within the slide housing so as to maintain a lubricating film on the reciprocating rod. The slide assembly finds particular application in a turf aerator of the vertical reciprocating tine type wherein the tines are caused to move transverse to their longitudinal axes during reciprocation.
