Couple of hopefully useful comments based on 15 years of living with a 406 Unimog with front loader and backhoe: First, make a good support for that front loader before you take it off and put it back on. A tall trailer jack makes a good starting point. Two trailer jacks, one on each side, are better. If the loader moves sideways on a prop, or breaks the 2x4, or tilts on the Highlift jack, it will take out some combination of hood, front clip, headlights or grill. No fun. Yeah, learned by doing.
For backhoe manipulation while on the ground, make up a pair of long hydraulic hoses so the mog can power the hoe before it is hooked up mechanically. You can then maneuver the hoe back into position for hook up. No matter how you support parts of the hoe, the hydraulics will let it shift shape like in a "Transformer" movie.
