A rake for attachment to a tractor and operation by the tractor hydraulic system. Rake tines are carried on an endless chain by pivotally mounted brackets along upper and lower runs with counterbalance means providing pivotal movement of the tines between folded and extended positions while traveling along the upper and lower runs, respectively. The rake may be moved to extend laterally outward from the tractor for raking between trees, and the like. The mounting and guide means for the chain and teeth-carrying brackets provide a sturdy and efficient raking action while avoiding clogging as brush is removed.
