I sided my little iseki tractor a few weeks ago. I got off really lucky, because a tree was almost in the way.
You can find some photo's here in this thread:

This little tractor has limited options to install a ROPS. But i can add a solid amount of weight to the bottom of the tractor on the structure of the FEL.
The question is: is there a maximum (or rule of thumb) on how much weight you can add to a tractor without hurting the structural integrity, or ability to manoeuvre?
The weight of my little iseki tx1300F is about 600 kg's (some 1300 lbs).
thanks, M.
