• said at least two feeding means being mounted upon a supporting frame which includes means to move said at least two feeding means into contact with said tree trunk and out of contact from said tree trunk,
• said at least two limbing means being mounted upon respective support arms pivotably mounted on respective feeding means, said feeding means each including a stop means which cooperates with each said respective support arm to prevent said limbing means from moving toward said tree trunk beyond a point in a plane defined by the contact surface of said feeding means with said tree trunk, each said support are adapted to pivot about a pivot axis parallel to said contact surface and located substantially in the plane defined by said contact surface with said tree trunk, and
