I have a 4 cylinder MF 35. Which I have used with all the implements you mentioned (and a baler). It was 37hp when it was new 50 odd years ago. I would go with a farm tractor rather than compact because matching implements are more plentiful second hand. My observations would lead me to believe they are generally cheaper than compacts which seem to bring a premium.
Most farm tractors are robust and long lasting and will easily do the tasks you are talking about, it's finding a good one and knowing its a good one that's the tricky bit.
Dealers will charge you a premium and might still sell you a dog.
I would favour Massey 135 or 165, but I am biased to MF because that's what I've mainly used. I've also used an international 434 which bring a bit less than the MF s. and are immensely strong. As I've said ford, John Deere , david brown, international all well proven.
They stopped making my model of MF in 1960 but I can get every single part for it on next day delivery.
Comment about value is correct, if anything old tractors seem to be going up in value. You certainly shouldn't loose if you decide to have a swap in a few years time.
If you want to run log splitters you need to have the right hydraulic connections. Most tractor can be adapted to suit, but if the right valves aren't already there you might easily spend another £100 sorting them out. Worth putting into the mix if buying from a dealer.
