Tractor with a bale spike and a muck grabber or at least a bucket of some kind
Stock trailer with 7' headroom or a livestock float if we're pushing out boats!
Brushcutter
A 60' (4 bay) yorkshire boarded barn or a set of old stone redes (can't buy those so would have to move but that's ok because it might come with an extra 20 acres please, tho that's not equipment
Cattle crush or similar that could be used for pd'ing ponies too
Serious set of pens around each gate, long enough to tow in a trailer off the road before opening internal gates
Double farmyard gates with pullover bar to widen my access off the road
A water trough off the mains at the furthest paddock so I can give up on the 6 hoses that run water down there through another field
A workshop full of power tools for furniture making - bandsaw, table saw/planer/thicknesser combo, big dust extractor and bagging system, good sturdy workbenches, pillar drill, turning lathe, big vices, lots of clamps, huge storage areas for lots of wood and a heater (woodburner ideally).. (sigh)
Actually a wood burning stove in the house too, the open fire isn't terribly economical with the heat it produces tho it does heat a backburner
Solar PV panels
.. (I could go on for quite some time!)
