First step is to get a proper manual. The factory manual explains the splitting process in detail; I'm not so sure about the IT manual.
The row crop is not that difficult to split. Gather up a bunch of 4x4s with which to build cribbing. You need to support the front end in three places: cribbing behind the front wheel to keep the front from tipping over, stands under the back ends of the frame, and a jack under the back of the engine. Once the bolts that hold the tractor halves together are removed, there's nothing to support the back of the engine, which is why it must be supported separately.
