Thanks mcmxi, I appreciate the comments. The weight was a concern, and the reason for my original post to seek some guidance. I know the cutter is at the technical limit, but the tractor is holding it well and I suspect there is a large safety margin in that number. I likewise don’t know the math on the cutter limit and cantilever weight, but the direct load limit is 3300 lbs. (big difference). The extra bushing is pretty much required to minimize lateral movement, and I don’t do anything at speed so I’m not bouncing it around. Neither the dealer nor the service technician hesitated in confirming the tractor would handle it, especially with the dual wheels. I needed some heavy duty capacity and I wanted to avoid the extra mechanical complexity of dual spindles. Anyway I am pleased with it but definitely paused before finalizing the purchase.
