Not much info on that tractor here
TractorData.com Massey Ferguson 283 tractor information
But it does mention a 2-stage clutch, which is true of a LOT of tractors - push the clutch in partway, tractor stops driving - rest of the way, PTO stops. That way you can do things like lift/clear a tiller without the tractor moving, etc.
IF you can raise the 3point with the clutch fully depressed, then your hydraulics are coming from a motor-driven pump and you may be able to find a place to "steal" a hydraulic feed for a FEL.
The hydraulics are open center on that tractor (typical) so all you'd need (besides some head scratching) would be a point prior to the 3-point control valve to cut into the pressure feed from the pump, a return to the 3-point valve from the Power Beyond outlet of the new valve(s), and a tee into the tank return circuit for the new valve(s) outlet.
Oh, and a good place to hang valves where they'd be reasonably ergonomic.
I'd recommend 3 or more valve setup, one with float for loader height, one center detented for bucket curl, and a spare for a grapple or other front add-on. You can also find a couple of ways to get a joystick setup to put lift and curl on the same lever. Very intuitive, my backhoe has that and it's great.
I'm just getting started on a 4-valve rear remote setup on an old allis-chalmers, and since yours is also made in either England or Brazil you may find existing high pressure hard tubing to be metric. Mine is 12mm.
Fortunately, Discount Hydraulics
DiscountHydraulicHose.com has you covered. They have metric compression - to - JIC, ORB, etc - adapters.
Gotta run for now, if I've got you curious ask away - I'm glad to share whatever I've found that might save you some headaches... Steve
