Finding parts for the Massey Ferguson 7485 is quick here: more than 350 items for this 7400 series type, with electrics, lighting and engine parts among them.
There is a lot of electrics on a Massey Ferguson 7485. Relays, rocker switches for four-wheel drive, PTO buttons out on the fender and work lamps all round the cab. When one of them fails the job often stops even though the engine runs perfectly. This page lists more than 350 parts for this tractor, from GRANIT, HELLA, Scharmüller, GRAMMER and MAHLE among others.
When a work lamp or a function suddenly stops, do not start with the expensive parts. First swap the relay with an identical one from a circuit that still works. If the fault moves with it, the relay is to blame. As you pull it, look at the pins and the holder as well: green corrosion or a scorched spot means a poor contact, and a new relay will only help if you clean or replace the holder too. A little contact spray and pushing the relay home squarely gives a solid connection. If the fault stays put, the fuse and the switch are next on the list.
Electrical parts include relays with holder, rocker switches with an orange rocker for four-wheel drive, push button switches such as the yellow PTO button for outside operation on the fender, and alternators. For lighting there are work lamps, among them a square recessed spotlight. Cooling is covered by a fan clutch and an electric cooling fan.
Around the cab you will find mirrors, gas struts for the rear window among others, a sealing ring for the rear window lock and handles. For the driver there are tractor seats, and at the back there are drawbars. Seals, for example for the fuel tank sensors, complete the list.
Model numbers in the 7400 range sit close together, so let the type plate confirm you have a 7485. Switches and relays often carry a printed number you can match with the product details. For mirrors and handles, check the side and the mounting.
Every tractor in this range has a page of its own, so if one of these runs alongside your 7485 you can see what fits it:
