Mike,
You took the thought right out of my brain. I've been following the sod discussion closely precisely because of my need to move building materials around. Not only brick and mortar, but lumber, plumbing fixtures, everything.
I've also been thinking about the
ballast question. The moment of 3,000 lbs (a pallet of sod) at a center of gravity distance of 5.2 feet from the front axle (at a pallet height of 77 inches) is 15,600 lb-ft. Not taking into account the weight of the Toolcat itself, the moment of 2,000 lbs ballast on the truck bed at a center of gravity of 7.5 feet back from the front axle is 15,400 lb-ft.
I can't tell for sure where the center of gravity of the Toolcat is without load, but if we figured it to be at the mid-point of the wheelbase, that would be 4,800 lbs at 3.5 ft. back from the front axle, or a moment of 16,800 lb-ft. It seems to me that if the loader can lift 3,000 lbs, the Toolcat shouldn't tip over.
Then if you add maybe 750 lbs of ballast on the truck bed and 200 to 300 lbs in the cab (for one operator), it seems to me that you have a margin of safety. Of course, at that point you have a total load of 4,000 lbs (3,000 + 750 + 250 lbs) which exceeds the machine rated capacity of 2,200 lbs., unless that capacity has been increased for the C-series. The Bobcat web site hasn't been updated since the C series came out last month.
I got these distances from the Bobcat pallet brochure (attached) and extrapolated from there on my CAD program. I'm not a physicist, so maybe someone else more knowledgeable can weigh in (no pun intended).
