I prefer to roll the front away from the rear when I do a split. I have split JD 2030s 6 or more times. With a helper, a person one each rear tire, moving the rear might be easier, but I work alone.
I made a single swivel wheel attachment to do my splits. I have seen two wheels, one each side on the engine to clutch housing that work well. IIRC, they were adjustable wheels from rolling scaffolds.
TxJim's tip to wedge the front axle is a MUST.
There are two bolts "hiding" under the shifter cover (holds the two shift levers). Also, one behind the transmission filter cover, that one's not hard to miss.
Don't forget to remove the rear brake hard lines. I use caps to seal every line I take apart. IIRC the brake lines are -03 JIC fittings.
There is a spring on one of the shift rails that has to come off (unless the tab for it on the rail is broken, very common). Spring is gone on my 2030, no worries.
Plan on replacing every O-ring/packing that is disturbed.
Picture is to show my splitting stand. For hydraulic fluid leak you will split clutch housing to transmission case, not clutch housing to engine, unless your clutch go oil on it. Also, notice the wooden wedge at the front axle. You need one for each side.
