1980 Massey 565 with front loader, about 60hp, 2wd.
We bought it as we needed something with a loader for handling round bales. Mostly it just gets used for loader work and one days baling hay per year.
Pros- it starts first time even if it's been sitting for months.
Cons- the weight of the loader combined with the lack of drive in the front wheels means it tends to dig ruts in the mud instead of steering, I try to avoid taking it off road in winter!
1958 Ford son Dexta, 30hp, 2wd. This does most of the work, flail mower, drum mower, hay Turner, harrows, occasional plough, tipping trailer. It has plenty power to run the conventional baler but as the baler is at least as heavy as the tractor it feels a bit like the baler is driving the tractor.
Pros- cheap, light, enjoyable to drive, can cope with bigger jobs than you might imagine, simple and generally easy to fix
Cons- it's 60 years old so oil seals etc etc need replaced now and then
Would I buy another Dexta? Absolutely, in the blink of an eye.
Would I buy another 565? Probably not, I would want 4wd in something that size.
