I agree with Bandit67 on the Woods hoe. Just the additional reach to me, makes it better! I made a decision in '78 for the construction of our new home, to purchase a bachoe for my Kubota L295DT. I was already "breathing through a straw," and was trying to save money with thoughts of buying the smaller hoe; the dealer said, you may reget it, the larger one (9') offers much more capability.
I still have the tractor and the larger hoe, and thank myself for one of the fewer wiser decisions. For trenching, you will have to move the tractor less, able to dig deeper, reaching in to difficult areas is a plus with the additional reach also. I think the quality of the Wood's is better too; and a future thumb may also be added.
