A couple of good ideas there. How did you fasten the saw scabbard in place? Unfortunately, I can't compare the picture to my tractor at the moment because it is in Maine and I am in New Jersey.
And the ammo box is just welded on to the frame?
I was trying to come up with some ideas of my own. I was thinking that something could be mounted between the vertical support of the ROPS. Another idea is to make a tray with handles that could be picked up with the grapple and carried with its cargo. Once on location, it could be set down so the grapple could be used. Once finished, it would be picked up again and carried out. The downside is that an extra trip might be required if you wanted to carry out a log in the grapple.
