Yes, if all goes according to plan and I am able to have the Red Beast maneuver the 20-ft equipment trailer out of my driveway past the 20-yard pile of loam (dumped by the town in the street)... I will get up to New Hampshire today to pickup the tiller and
get the shaft as well. On sale, the entire 72" KK tiller with drive cost $1,299.00. No sales tax in New Hampshire either!
BTW, I noted yesterday that this pile of loam they dumped right in my trailer's "flight path" is the very last one on the whole street. Originally, there were 7 or 8. Now there is just one left... untouched and just sitting there throughout the Labor Day weekend and probably longer. Guess whose driveway they chose to block???

Oh yeah, the trouble-making guy with the two trailers!!!

Who else???
No clue on why the Bradco thumb cylinder is taking so dang long. Bob Wolff was supposed to call or email back with an explanation last week, but never did. I am not a happy camper since I could drive to the local Bradco distributor in 75 minutes and get one myself... 'cept the distributor does not do retail business.

Now it is 4 weeks and Labor Day is here. Guess I should have ordered the Prince alternative cylinder right away after all. I'd have had it by now and saved half the cost.

Just the "luck" of the poor old Dougster.
Don't blame you for wanting to do the hydraulic thumb and grapple right, even at a much higher initial cost. It makes sense for the 6520 and you already have a supplier you trust. My "reach back over the fuel tank and work the remote lever" approach is perfectly easy & workable on the 4110... but I would never recommend it for models I hadn't personally tried.
