The HTC offered by Bobcat refers to a "Hydraulic Traction Control" system which acts much like the limited slip differential in a pick up. It does help in low traction situations, but certainly isn't a locking diff.

The traction control sends the power to the wheel(s) slipping the least. It helps out a lot in most conditions. However, I still find myself spinning some wheels that are on very slick surfaces. It is not a locking differential and probably not as good as a limited slip differential.
It IS a limited slip differential. The TC axle uses the same technology used in pickup trucks and cars for many years. A quick internet search on thoery of operation is exactly how it works. It has clutches inside the differential that lock to transmit power to both sides of the axle. The drawback it that it can only transmit power to the non slipping wheel at the rate of torque available on the slipping wheel (plus some internal clutch spring preload). If there is not enough slipping wheel torque to transmit to the non slipping wheel, the axle will not drive. The front and rear axles are exactly the same.
