The most common size for grease fittings on loader arms is 1/4"-28 SAE.
The tractor itself will likely have a mix of metric and SAE on different parts, but the loader, especially on that model, often uses the imperial standard.
Your best bet is to grab a 1/4"-28 from the hardware store, and if it doesn't thread in by hand easily, it's probably a different size.
