Listed under the T7 Autocommand in the parts catalogue, the New Holland T7.225 has more than 190 matching parts, such as couplings, electrics and linkage parts.
A New Holland T7.225 from the T7 Autocommand line carries a lot of electronics, and when a warning appears on the display a sensor is often behind it. This page holds more than 190 parts for the T7.225, from GRANIT, Scharmüller, ROCKINGER, Sauermann and FEBI.
For the back of the tractor there are drawbars, drawbar frames, adapter plates, Piton Fix couplings, automatic hitches and linkage drawbars. Connector heads join the trailer brake lines. On an automatic hitch, the locking pin wears over the years. Check it together with the catch at every service so a trailer cannot come loose unexpectedly. Mirrors help you keep an eye on what is behind.
There are NOx sensors, temperature sensors, other sensors and potentiometers. The NOx sensor sits in the exhaust and checks whether the aftertreatment is doing its job. Let the exhaust cool before swapping one. Thread the new sensor in with suitable anti seize compound and the specified torque, then route the cable back into its old clips, away from hot parts. Otherwise the insulation melts or a wire breaks from vibration.
For the cab there are aircon compressors. A new compressor calls for a new receiver drier and a clean circuit. Add the correct amount of compressor oil and have a qualified workshop charge the system afterwards. You will also find a torsion damper for between engine and gearbox, and tank caps.
A tank cap has a vent. If it blocks, the tank goes under vacuum and the engine starts to pull poorly after a while, then runs normally again once the cap is opened. That is a simple test before you start on filters or pumps. A potentiometer reports the position of a rotating part to the electronics, and erratic readings usually mean the wiper track is worn.
A mirror that has taken a knock from a branch and now vibrates makes reversing with a trailer harder than it needs to be. Swap the glass or the whole mirror once the image becomes unsteady.
You need two things: the serial number from the type plate and the reference number on the old part. With sensors, the plug is a useful extra check. Pin count and shape should match the one you took out.
From the same series, the New Holland T7.270 has its own page. For any other model from the brand, start at New Holland parts.
