I have a Lane Shark that I bought in May 2018. First one sold in WV I believe. I had it installed on my MF 2660 by the Shark dealer (who happens to be primarily a Kubota dealer.) And thankfully so ! Glad I did not attempt the plumbing myself though I thought I had it down pat. I had a completely separate set of larger diameter lines run alongside my age-old third function lines that I normally use for a pinch bucket up there. USE 1/2" LINES not any less.
Lane Shark has the bugs out of this product and the user friendly aspects of such devices figured out very, very well. I previously tried a much larger heavier hydraulic motor driven front cutter which worked but NOT very well. Problems included lack of adequate pump flow, no provision for freewheeling when you shut off the drive and failure to understand the need to return flow to the sump rather than via the remotes. All these matter. The Lane Shark people are absolutely super in terms of customer support, talking through your issues and getting things working right.
The Shark is designed for a mid-sized farm tractor to readily drive it as opposed to a skid steer with a big hydraulic pump putting out upwards of 20 gpm. Mine runs with a motor said to need 10 gpm and that is ideal. Even if your machine says it puts out 14 to 17 gpm (which mine did) that is not what really happens at the business end due to hose diameters, fitting losses, valve losses, etc.
You may want to talk to the Lane Shark people because (as I read Tractor Data) your Kubotas put out less than 10 gpm specified and that means less yet at the business end of the hoses. Lane Shark has used and tested their Shark on some models of Kubota, I just do not know which ones, and I would trust their word on what does and does not drive it well. You don't want to just turn the blades, you want to be robust in ability to cut with it.
Lane Shark has come out with much better heavier blade carriers and blades with a better attachment for the blades than my early copy. They sent the new hardware to me free of charge and I have not gotten it installed yet, but it is obviously better in terms of heavier cutting capacity and mainly in the blade attachment bolt area. I threw some blades in early usage and the new blade attachment bolt configuration certainly should cure that disease (which was the only complaint I had.)
I like the unit so well that I am about to put a large rear mounted boom cutter up for sale and use the Lane Shark from now on. About 1/3 the cost of the big boom cutter and while not as big or as much reach, it will do what I need to do most.
Sad note: Titan now sells what they call a "Trailblazer TB-One" which is obviously a knockoff copy of the Lane Shark. I was told that Titan bought one of the Lane Sharks and not long after began marketing and selling what I'll call a "Chinese Copy" which to me is unethical or worse. I stumbled across the Titan literature at a tractor dealer and said Hey ! That's my Lane Shark !
