Does sound too good to be true, but I just checked and the ad's still up. At least it's not one of those CL ads with a FACTORY picture... Steve
I have that exact same Case setup, came off a Case 530 tractor - fits the old 580's that had a subframe mounted hoe. If I've done it recently, it takes about 30 minutes to remove the hoe and put on the TnT.
Also, with the subframe setup you have top, tilt, and the lift is set up just like a loader - power up, power down, and/or float. But NO POSITIONING control like a normal 3ph. Controls include one extra remote. Perfect for hydraulic rippers.
Still, the combo of front bucket and Gannon with hydraulic rippers can move a crapload of material - I used mine to do a 200 foot square push-out, moved approx. 2500 cubic yards of dirt in 3 days. A few side hill passes with rippers down, then rippers up - drive the bucket in deep going downhill til it's full, roll it out and into float while dropping the box blade with some power down, then full box into float, all the while with my heel on the differential lock. Occasionally had to lift loader bucket slightly for traction.
Get to bottom of pushout, lift/dump bucket, then just as tractor started to break over the hill, pop the box up, let up on differential lock rolling straight down the hill, drive around to the top and repeat.
C'mon, SOMEBODY on the west coast needs to go look at this
