Trailer couplings, electrics and lighting are the main groups for the New Holland TVT195. Altogether you can pick from more than 200 parts that fit.
The New Holland TVT195 has plenty of switches, relays and lights, and a hood that comes up at every service. This page lists more than 200 parts matched to the TVT195, from GRANIT and from makers such as Scharmüller, ROCKINGER, Carraro and GRAMMER.
For the electrical system there are alternators, changeover relays, rocker switches for the dashboard such as the one for the front work lights, and push button switches, for example for lowering the front linkage. Work lamps are here too.
If the battery is not charging properly, do not reach for a new alternator straight away. Check the belt tension, the charging cable and the earth connection first. A slipping belt or a loose cable lug looks just like a worn alternator. With the engine running, measure the voltage across the battery terminals, and only when it stays low with belt and cables in good order is the alternator to blame. When a function stops working completely, a failed relay is often quicker to track down and replace than a switch.
A hood that will not stay up on its own means the gas struts have lost their force. Replace them as a pair so the hood is not pulled out of line, and fit them rod down.
For the rear there are automatic drawbars, top drawbars, adapter plates and Piton Fix pins. Which plate or pin fits depends on the rail width of the mounting on your tractor and the diameter of the locking pin, so measure both before ordering.
Check that your type plate reads TVT195. For switches and relays, also compare the connector and the number of terminals with the old one. Gaskets and O-rings sometimes carry a reference number, and otherwise you take the size from the part you removed.
If you run more tractors from the TVT series, each has its own page with matching parts: New Holland TVT145, New Holland TVT170 and New Holland TVT190. Similar as they look, always order for your own type. Every other New Holland model is on New Holland parts.
