Why not just load your tires? They have started using something new here in WA, beet juice! won't rust or corrode your wheels is environmentally friendly won't freeze down to a certain temp don't remember what that is, weighs about eight pounds to the gallon.
I also should have added that the tires are loaded. I just want a little extra weight on the rear. It is not always easy to attach a counter weight on the 3 point hitch. Some of my land is rough and hilly, amd sometimes I use it in tight places. Thanks
It appears that the new website for Kioti doesn't have the wheel weights listed, nor are they listed under the tractor's specs.
I'm fairly sure that I saw them offered under the old website, so check with a Kioti dealer.
I'd be careful about adding wheel weights to loaded tires. I know many people do, but make sure you find out the MFG recommendation on ballast maximums.
