I use a converted Thwaites 4x4 2 ton dumper. It's wide, which means it's good on a side slope, but it's articulated so it has a good turning circle.
It has agri tread tyres, 4 wheel drive, a hand start 1600cc diesel Lister engine - so no battery or electrics to worry about, and decent hydraulics built in. Although the ancient engine is rated at a paltry 8.2HP the 1st gear is very low and it has pulled everything I have tried, the limiting factor is wheelspin even with tractor pattern tyres.
Mine has a lifting arm at the front which is useful for stacking stuff and will easily lift a builders skip bag full of chopped logs.
Worth a look.
