The invention comprises an improved cordwood cutting saw accessory for small garden tractors. The saw frame is proportioned and constructed to provide a safely operable saw attachment without the need for auxiliary stabilizing supports and level ground upon which to park the tractor and operate the saw. The saw frame is cantilevered from the front of the garden tractor the minimum horizontal distance necessary to support a circular saw blade and shaft adjacent the top of the tractor cowl. The elevation of the saw is substantially between the waist and shoulders of the saw user. The vertical height of the saw frame is equal or greater than the horizontal cantilevered length of the saw frame and two or more times the height from the ground of the cantilevered attachment to the tractor. The accessory thereby does not seriously disturb the stability of a light small garden tractor despite the capability of cutting cordwood logs of any size that can be conveniently lifted and placed on the saw table or feeder by a single operator.
A vehicle transportable cordwood cutting machine attachable to a vehicle so as to be transportable in operable mode, said vehicle having a frame, said machine comprising at least two horizontal frame members, means at one end of each of said two horizontal frame members for cantilevered attachment to said vehicle frame, said horizontal frame members thereby extending outwardly from said vehicle frame, at least two vertical frame members extending upwardly from and joined to said horizontal frame members, each of said vertical frame members at a position spaced from said cantilevered attachment, the height of said vertical frame members above said horizontal frame members being at least twice the elevation of the horizontal frame members above the ground upon which the vehicle is supported, wood cutting means supported on said vertical frame members adjacent the top thereof, means including a power train for powering said wood cutting means, a pair of support members pivotably mounted on one end of said horizontal frame members, a saw table made fast to the upper ends of said pivotable support members constructed to hold a length of cordwood thereon widthwise of said frame members, means yieldably biasing said saw table into an at-rest position disposed away from said wood cutting means, said saw table capable of moving past said wood cutting means when the user pushes against a length of cordwood held on said saw table so as to cut the same into the desired length.
A tractor transportable cordwood cutting machine comprising a substantially horizontal frame, means for cantilevered attachment of one end of the horizontal frame to the front end of the frame of a small tractor below the cowl thereof, a second frame attached to and extending generally upwardly from the horizontal frame at a position spaced from the cantilevered attachment, wood cutting means mounted on the upper portion of the second frame a distance above the horizontal frame at least equal to the length of the horizontal frame, means adapated to provide power to the wood cutting means and means adapted to support and move cordwood into contact with the wood cutting means, said machine transportable in operable mode entirely supported by the cantilevered attachment to a tractor.
A vehicle transportable cordwood cutting machine comprising a substantially horizontal frame, means at one end of said horizontal frame for cantilevered attachment to the frame of a vehicle, said horizontal frame extending outwardly from the vehicle, an upwardly extending second frame attached to the horizontal frame at a position spaced from the cantilevered attachment, wood cutting means mounted on said second frame a distance above the horizontal frame greater than twice the elevation of the horizontal frame above the ground upon which the vehicle is supported, means adapted to provide power to the wood cutting means, and means adapated to support and move cordwood into contact with the wood cutting means, said machine transportable in operable mode entirely supported by the cantilevered attachment.
