Part of the New Holland Operator Manuals.
The rear axle on a TC23DA shares its oil with the transmission and the hydraulic system, so one careless fill can hurt all three at once. The Lubrication and Maintenance section of this New Holland operator manual walks that shared sump along with the fuel filter, air cleaner, lubrication fittings, and cooling system, with the service intervals that keep a small diesel healthy between seasons.
New Holland issued it as publication 87544694 for the TC23DA and TC26DA compact tractors. Across 108 pages it also covers safety, the instrument panel, starting the engine, the main shift and range levers, brake controls, and a Specifications chapter with capacities and torque figures for both models.
When the mower is hitched, the weather is turning, and there is nobody around to ask, the 24 bookmarks and the index take you straight to the page you need, and any of it prints one sheet at a time for the bench.
