It has been sometime since I asked about installing spaces on my Kubota GR2120, approximately two years. Well, finally I purchased 2 inch spacers from Bro-Tek and installed them yesterday. They fitted great and I'm now able to use chains. Now the question is: can I install my 55 inch mower without removing my spacers. The instructions for the spacers state 48 inch mower will be ok and possibly 60 inch but nothing on 55 inch mower. Will be watching the forum on what answers I will receive.
