       9 . The device of  claim 1 , wherein the telescoping mast further comprises:
 a telescoping mast hydraulic cylinder attached at one end to a bracket attached to the outer mounting member of the telescoping mast assembly and at the other end to a bracket attached to the slidably extending inner member of the telescoping mast assembly; and   hydraulic lines connecting the telescoping mast hydraulic cylinder to a hydraulic power source on the vehicle.   
   
   
       10 . The device of  claim 1 , wherein the upper arm is a telescoping upper arm further comprising:
 an upper arm outer member;   a slidably extending inner member disposed within the upper arm outer member;   a telescoping upper arm hydraulic cylinder attached at one end to a bracket on the upper arm outer member and at the other end to a bracket on the slidably extending inner member; and   hydraulic lines connecting the telescoping upper arm hydraulic cylinder to a hydraulic power source on the vehicle.   
   
   
       11 . A positioning system for attachment to a vehicle for operation of a power tool by a ground-based operator sitting in the vehicle, the positioning system comprising:
 a four-point linkage consisting of a horizontal base attached to the vehicle, a horizontal top, two parallel vertical members, each parallel vertical member pivotally attached at one end to the horizontal base and pivotally attached at the other end to the horizontal top;   a telescoping mast having an upper end portion and a lower end portion, wherein the lower end portion is attached to the horizontal top;   a pivot bracket connecting an upper arm to the upper end portion of the telescoping mast, the upper arm having a proximate end adjacent the pivot bracket and a distal end distal from the pivot bracket;   mounting means for attaching a power tool to the distal end portion of the upper arm; and   power means for operating the power tool from the operator's position in the vehicle.   
   
   
       12 . The device of  claim 11  wherein the horizontal base of the four-point linkage is attached to a dirt bucket on a tractor. 
   
   
       13 . The device of  claim 12 , wherein the power tool is powered by a hydraulic motor. 
   
   
       14 . The device of  claim 11 , wherein the horizontal base of the four-point linkage is attached to a pickup. 
   
   
       15 . The device of  claim 14  wherein the power tool is powered by a pneumatic motor. 
   
   
       16 . The device of  claim 11 , wherein the horizontal base of the four-point linkage is attached to a bale spike frame. 
   
   
       17 . The device of  claim 11 , wherein the power tool is powered by a pneumatic motor. 
   
   
       18 . The device of  claim 11 , wherein the telescoping mast further comprises:
 an outer mounting member having at least two bores at the lower end portion of the outer mounting member for attachment of the outer mounting member to the vehicle;   a slidably extending inner member disposed within the outer mounting member;   a locking pin bore within the outer mounting member;   at least two spaced bores in the slidably extending inner member; and   a locking pin disposed within the locking pin bore in the outer mounting member and one of the at least two spaced bores in the slidably extending inner member.   
   
   
       19 . The device of  claim 11 , wherein the telescoping mast further comprises:
 a telescoping mast hydraulic cylinder attached at one end to a bracket attached to the outer mounting member of the telescoping mast assembly and at the other end to a bracket attached to the slidably extending inner member of the telescoping mast assembly; and   hydraulic lines connecting the telescoping mast hydraulic cylinder to a hydraulic power source on the vehicle.
