Now simply start machine and reverse the track. Roll the bars until all four are on the front idler. This raises the center bars clear of the idler.
I just grabbed the front of the track with a hook on a chain and pulled it off with the forklift. Once you get the idler end off, the rest is pretty easy.
When you go to put track back on, get it onto the drive sprocket and rear idler, then work the inside of rubber track on the front idler. Put your pipes/bars back in place on bottom of track, roll the track back, then simply push track onto front idler. Roll the track forward and remove the pipes.
