If you work with a Massey Ferguson 6613, the matching parts are already sorted here: more than 250 parts, including trailer couplings, electrics and lighting.
Drawbars, drawbar frames and forced steering parts for trailers make up the hitch side of this page. Think of a black drawbar with a K80 ball on a rail, or forced steering welded at both ends with a K50 lock. Before you order a new drawbar, measure the rail width and pin diameter on the frame already fitted to your Massey Ferguson 6613. Replace a pin that has worn oval at the same time, because play in the hitch grows with every pull away.
Because so much of the work on a 6613 happens at the hitch, it pays to keep an eye on the drawbar, the drivetrain and the cab together. A rattling hitch, a clutch that bites a little later than it used to or a door that lets in draughts are often the first signs. Dealing with them early saves bigger repairs later on.
In total there are more than 250 parts here that fit the 6613. Next to GRANIT you will find components from Scharmüller, DANA Spicer, HELLA and Walterscheid.
Further inside the tractor there are internal and external clutch plates, adjusting plates for the bevel gear in the front axle, O-rings and sealing rings. Clutch plates are always replaced as a full pack. Soak the new plates in clean transmission oil before assembly, so the lining is fully saturated before the clutch takes its first load. The adjusting plates set the backlash between pinion and crown wheel, so reuse the exact thickness you removed or measure the backlash again if bearings or housing are renewed.
For the cab there are work lamps, control knobs, gas struts and seals, including the seal around the door handle. On the cooling side you get radiator hoses and temperature sensors, one of them for the air conditioning. A radiator hose that feels hard or spongy when squeezed is ready for replacement, even if it has not started leaking.
The type plate confirms you are working on a 6613 and not a close relative. A reference number on the old part is the safest thing to compare with. The tractor is part of the Massey Ferguson 6600 series, and the other types in that series have their own pages with parts that fit them: Massey Ferguson 6614, Massey Ferguson 6615 and Massey Ferguson 6616.
