This innovative forestry attachment processes and loads eliminating the need for two machines in some applications. This is a video that demonstrates the processing capabilities of the Pierce GP. Mounted on a Madill 2800C. The new GP from Pierce Pacific. Logs like a grapple and measure, cuts, delimbs like a processor. This head has been in operation for over a year. Working under the Yarder. The new Peirce GP in action. Grab multiple logs, load trucks, cut to length, delimb, all in one tool.
