Abstract:
1. An apparatus for handling wood products, comprising: a frame configured to be supported at least in part by a ground surface; an anvil surface supported by the frame above a ground surface; and a rotatable drum carried by the frame and configured for (1) operating with the anvil surface in a first mode for chipping or grinding loose tree parts, and for (2) operating in a second mode for grinding a stump in the ground, the rotatable drum being selectively movable with respect to at least one of the ground surface or the frame between a first position wherein the drum is positioned away from the ground so the ground does not obstruct rotation of the drum and proximate to the anvil surface to cooperate with the anvil surface to chip or grind the loose tree parts in the first mode, and a second position wherein the drum is positioned adjacent the ground to engage a stump and grind the stump in the second mode; a feed roller assembly positioned upstream of the rotatable drum and proximate the anvil surface and including a feed roller housing and a feed roller in the housing, the feed roller configured to rotatably engage loose tree parts received by the housing and move the loose tree parts through the housing and toward the drum and anvil surface in the first mode for chipping the loose tree parts; and a shroud configured to encase at least a portion of the drum the shroud including a first shroud section selectively moveable to expose a first portion of the drum in the first mode and expose a second portion of the drum different from the first portion in the second mode.
