Abstract
A tractor carries a vertically adjustable frame supporting a horizontal shaft for a supply roll of silt fence fabric. A flat vertical plow blade is mounted on the frame and has a front surface and a rear surface. A thinner flat vertical fin is supported directly behind the plow blade by a horizontal fabric guide bar attached to the frame. The fin has a downwardly and rearwardly curved front surface for receiving an intermediate portion of the fabric directed around the guide bar and for folding an edge portion of the fabric into the slot formed by the plow blade. After the ground is compacted by a tractor wheel, wood stakes are driven into the ground by a hydraulically actuated cylinder device mounted on a side of the tractor frame between the front and rear wheels, and the fabric is attached to the stakes.

Apparatus adapted to be mounted on a tractor for inserting a series of stakes into the ground at horizontally spaced intervals, said apparatus comprising a generally vertical elongated support tube, a stake guide member enclosed by and supported by said support tube for generally vertical movement, an elongated hydraulic cylinder enclosed by and supported by said support tube and having a downwardly projecting piston rod, a stake pressing member connected to said piston rod and supported for generally vertical movement within said stake guide member, said stake guide member having an opening for inserting a stake into said stake guide member under said stake pressing member, and said stake guide member moves generally vertically within said support tube in response to vertical movement of said stake pressing member.
Apparatus adapted to be mounted on a tractor for inserting a series of stakes into the ground at horizontally spaced intervals, said apparatus comprising a generally vertical elongated support member, a stake guide tube supported by said support member for generally vertical movement, an elongated hydraulic cylinder supported by said support member and having a downwardly projecting piston rod, a stake pressing member connected to said piston rod and supported for generally vertical movement within said stake guide tube, said stake guide tube having an opening for inserting a stake into said stake guide tube under said stake pressing member, and said stake guide tube having a lower end portion with a lateral opening to permit said guide tube to move forwardly with the tractor while an upper portion of the stake remains within said guide tube.
Apparatus in combination with a tractor having a frame supported by a pair of front wheels and a pair of rear wheels, for inserting a series of stakes into the ground at horizontally spaced intervals, said apparatus comprising a generally vertical elongated support member, a stake guide member supported by said support member for generally vertical movement, an elongated hydraulic cylinder supported by said support member and having a downwardly projecting piston rod, a stake pressing member connected to said piston rod and supported for generally vertical movement within said stake guide member, said stake guide member having an opening for inserting a stake into said stake guide member under said stake pressing member, and a mounting bracket connecting said support member to said frame of said tractor between corresponding said front and rear wheels on one side of said tractor and laterally inwardly of said corresponding wheels.
Apparatus adapted to be mounted on a tractor for inserting a series of stakes into the ground at horizontally spaced intervals, said apparatus comprising an elongated generally vertical support tube, a stake guide tube supported by said support tube for movement within said support tube, an elongated hydraulic cylinder supported within said support tube and having a downwardly projecting piston rod extending into said stake guide tube, a stake pressing ram connected to said piston rod within said stake guide tube for generally vertical movement within said guide tube, and said support tube and said stake guide tube have laterally extending openings for inserting a stake into said stake guide tube under said stake pressing ram.
Apparatus mounted on a tractor having a frame supported by a pair of front wheels and a pair of rear wheels for inserting a series of stakes into the ground at horizontally spaced intervals, said apparatus comprising a generally vertical elongated support member, a stake guide member supported by said support member, an elongated hydraulic cylinder supported by said support member and having a downwardly projecting piston rod, a stake pressing member connected to said piston rod for generally vertical movement within said stake guide member, and a mounting bracket secured to said support member and connecting said apparatus to said tractor between said front and rear wheels on one side of said tractor and laterally inwardly of said wheels.
