Part of the New Holland Parts Manuals.
Hunting for the right part number for your TG-series tractor? This 527-page New Holland TG285 parts catalog PDF covers the TG210, TG230, TG255, and TG285 with factory exploded views for every assembly. You get complete engine breakdowns, from the turbocharger and wastegate actuator down to pistons and gasket kits, plus full drivetrain sections: speed and range transmissions, MFD front axles with and without Super Steer, PTO assemblies, and rear planetaries. Cab, hitch, hydraulic pump, remote coupler, and electrical harness pages all carry numbered callouts tied to factory part numbers, so you can identify a component before you ever pick up the phone. Match parts exactly: the 135-amp alternator assembly, the 15 psi radiator pressure cap, even the 610 mm coolant hose. Ordering the wrong part twice kills a whole week. Bookmarked by section and text-searchable; type a part name, jump to the figure, order once.

New Holland TG255, TG285, TG210, TG230 Common Problems This Manual Covers
New Holland TG255 upper radiator hose cracked, can't find the replacement part number in the book
Check the engine parts diagram for radiator hose callouts and part numbers. Refer to the 02-03 DEAERATION SYSTEM section for the correct radiator hoses before ordering. While the parts list is open, confirm the pressure cap is the 15 psi unit shown on page 13.
Manual Section: Radiator and Fan ShroudAlternator dead, need the correct part number and amp rating before ordering a replacement
Verify the alternator spec first: all four models run a 135 Amp unit, listed on page 132. Use the figure search feature explained on page 1 to jump to the charging system figure, read the callout part number from the exploded view, and confirm your serial number range in the parts list.
Manual Section: How to Use Figure Search p. 132Engine block heater element burned out, not sure which wattage unit fits
Verify the element matches the 1000W block heater listed on page 52 before ordering; do not substitute a different wattage. Check the engine parts diagram for the heater location and gasket callouts, then record part numbers for the element, cord, and seal before calling the parts counter.
Manual Section: Water Pump System p. 52Hydraulic piston pump and filter part numbers hard to match to serial number range
Check the hydraulic parts diagram for the piston pump, filter, and line callouts. Match each callout to its part number in the parts list, then confirm your tractor serial number falls inside the listed range. Cross-check metric fitting sizes with the conversion table on page 526 before ordering.
