Wheel spacers for L3901

[KBinCT]

I've got a L3901 and am considering the purchase of some wheel spacers. What does everyone use/recommend? 1", 1.5", 2", 3"? I'm going to be using it hauling firewood on uneven/hilly ground. Thanks.

Interested in doing the exact same thing with my L3901. Noticed the width is actually less than on my old L2250 I had and it just seems a bit less stable. I was told that Kubota only has the 1.5 inch and they ain't cheap. Not sure if its worth it for a total of 3 inch width increase. Have you been able to get additional info on wider spacers?
