Mini-skid steer loader extractor

Abstract

A tool or extractor which is lightweight and portable. The tool includes a plate which is mountable to a mini-skid steer loader. The tool includes a first jaw member which is fixed. The first jaw member is preferably welded or otherwise attached to or engaged with the plate. The tool also includes a second jaw member. The second jaw member is moveable, such as via a hydraulic cylinder, and is pivotably connected the plate. The hydraulic cylinder is also preferably pivotably connected to the plate, and is controlled in order to affect a grip on a thing to be extracted. The mini-skid steer loader is then operable to pull up on the thing, and extract the thing from the ground.

What is claimed is: 
     
         1 . A hydraulically-operated post-pulling apparatus adapted to be mounted to a mini-skid steer loader, said apparatus comprising: a plate configured to be mounted to the mini-skid steer loader; a first, fixed jaw member engaged with the plate; and a second jaw member mounted to the plate and moveable relative to the first, fixed jaw member. 
     
     
         2 . The post-pulling apparatus as recited in  claim 1 , wherein the first, fixed jaw member is attached to the plate. 
     
     
         3 . The post-pulling apparatus as recited in  claim 1 , wherein the first, fixed jaw member is welded to the plate. 
     
     
         4 . The post-pulling apparatus as recited in  claim 1 , wherein the second jaw member is pivotably connected the plate. 
     
     
         5 . The post-pulling apparatus as recited in  claim 1 , wherein the second jaw member is moveable, angularly generally toward and away from the first, fixed jaw member. 
     
     
         6 . The post-pulling apparatus as recited in  claim 1 , wherein the second jaw member is hydraulically operated. 
     
     
         7 . The post-pulling apparatus as recited in  claim 1 , wherein the second jaw member is pivotably connected to the plate, via two hinges which are provided by arms which are connected to the plate. 
     
     
         8 . The post-pulling apparatus as recited in  claim 1 , further comprising an arm connected to the plate, and a hydraulic cylinder, wherein one end of the hydraulic cylinder is hingedly connected to the arm which is connected to the plate, while an opposite end of the hydraulic cylinder is hingedly connected to an arm of the second jaw member. 
     
     
         9 . The post-pulling apparatus as recited in  claim 1 , wherein each of the first, fixed jaw member and the second jaw members comprises teeth. 
     
     
         10 . The post-pulling apparatus as recited in  claim 1 , further comprising a hydraulic cylinder connected to the second jaw member, and a controller which is configured to control the hydraulic cylinder and move the second jaw member relative to the first, fixed jaw member. 
     
     
         11 . A hydraulically-operated post-pulling apparatus adapted to be mounted to a mini-skid steer loader, said apparatus comprising: a plate configured to be mounted to the mini-skid steer loader; a first, fixed jaw member engaged with the plate; a second jaw member mounted to the plate and moveable relative to the first, fixed jaw member; and a controller which is control movement of the second jaw member relative to the first, fixed jaw member. 
     
     
         12 . The post-pulling apparatus as recited in  claim 11 , wherein the first, fixed jaw member is attached to the plate. 
     
     
         13 . The post-pulling apparatus as recited in  claim 11 , wherein the first, fixed jaw member is welded to the plate. 
     
     
         14 . The post-pulling apparatus as recited in  claim 11 , wherein the second jaw member is pivotably connected the plate. 
     
     
         15 . The post-pulling apparatus as recited in  claim 11 , wherein the second jaw member is moveable, angularly generally toward and away from the first, fixed jaw member. 
     
     
         16 . The post-pulling apparatus as recited in  claim 11 , wherein the second jaw member is hydraulically operated. 
     
     
         17 . The post-pulling apparatus as recited in  claim 11 , wherein the second jaw member is pivotably connected to the plate, via two hinges which are provided by arms which are connected to the plate. 
     
     
         18 . The post-pulling apparatus as recited in  claim 11 , further comprising an arm connected to the plate, and a hydraulic cylinder, wherein one end of the hydraulic cylinder is hingedly connected to the arm which is connected to the plate, while an opposite end of the hydraulic cylinder is hingedly connected to an arm of the second jaw member. 
     
     
         19 . The post-pulling apparatus as recited in  claim 11 , wherein each of the first, fixed jaw member and the second jaw members comprises teeth. 
     
     
         20 . The post-pulling apparatus as recited in  claim 11 , further comprising a hydraulic cylinder connected to the second jaw member, wherein the controller is configured to control the hydraulic cylinder and move the second jaw member relative to the first, fixed jaw member.
