If you run a New Holland T7.220 from the T7 series, choose from more than 250 parts here, from trailer couplings and electrics to steering and front axle.
A New Holland T7.220 is a tractor you spend long days on, so this page starts in the cab. An air suspended seat that keeps sinking, a cracked mirror or a push button that has stopped responding makes the work harder than it needs to be. For the T7.220 there are more than 250 parts on this page, from the driver station to the coupling at the rear.
For the cab there are air suspended tractor seats in fabric, mirrors that fit Case IH and New Holland, and push button switches. If an air seat slowly sinks, listen for escaping air at the air spring or the small hoses first. A leaking hose is quicker to fix than a new compressor, and it is often the whole problem.
At the back of the T7.220 it is all about coupling up. You will find automatic drawbars, top drawbars, Piton Fix rails and automatic hitches, plus height adjustable adapter plates to set the coupling at the right height. Parts for the forced steering of a steered trailer and connector heads for the air brake line belong here too. These hitch components come from makers such as Scharmüller, ROCKINGER, Sauermann and Walterscheid.
On an automatic hitch, check the coupling pin and the bush in the drawbar eye of the trailer regularly. Once there is noticeable play, the trailer knocks against the pin every time you brake or pull away. Replacing a worn pin in good time keeps the hitch jaw itself from wearing out.
There are also hydraulic top links and hydraulic cylinders, a transmission oil temperature sensor, oil pressure switches for the steering among others, alternators and further sensors. GRANIT rounds this off with service and wear parts. When an alternator stops charging, it pays to clean and tighten the earth connection and cable lugs first. A poor earth produces exactly the same symptoms.
The type plate on the tractor confirms you are working on a T7.220. If that still leaves doubt, check the number stamped on the part you removed and compare it. On a sensor, alternator or switch it is usually stamped or printed on. Compare that number with the details given for the product before you order. For an automatic hitch or adapter plate, measure the rail width on your own tractor.
The other models in the T7 series each have their own page. If you run several tractors, that is where you see what is available for each one: New Holland T7.170, New Holland T7.200, New Holland T7.210, New Holland T7.230, New Holland T7.245 and New Holland T7.260. The overview for the whole brand is at New Holland parts.
