Haymaking machine with pivoted tines - has rake wheel with lubricated cams which act on carrier arms

摘要

The haymaker has a rake wheel with a number of tool carrying arms which extend outwardly. At the inner end, each arm has a control arm (18) to which a roller (19) is secured. The rollers run in a cam track (20) causing the arms to pivot over at least part of their trajectory. Lubricant may be delivered to the cam guide surface (23) via the central part of the rake wheel.
