Just saw your filter guard.....and I made my dealer install one like that from a post I saw on TBN. They fabbed it up to my drawings ......and now they put them on all 3560's. I made my own mesh grill guard and have saved the front screen more than once from a tree branch when using my grapple. Trees are hard on tractors.
I've got a six foot bush hog for sale. I have not used it in a few years.....The paint is faded (Kubota Orange) bit the cutter is in super condition and was not used much (was my son in laws). Not sure on prices these days....but it would be fair.
Also have a KK 5 foot Box Blade that I have not used in 5 years. CHEAP. I used it for counter balance mostly....and had suitcase weights hung on the back. The last time I used it I backed into a tree with my Kubota.....and bent the bars that go to the top link. Replace or straighten those and it would be a good unit.
Not sure where you are located?
