The GIANT G904C-TD is a 90 hp four-wheel-drive tractor powered by a turbocharged four-cylinder, 3,920 cc Stage II engine. It uses a 16-forward and 16-reverse transmission with a double-action clutch and independent PTO, supported by power steering, oil-immersed brakes and a mechanically operated differential lock.

Its hydraulic system delivers 77 litres per minute at 2,400 rpm and provides a rated lift capacity of at least 23 kN, measured 610 mm behind the suspension point. Category 2 linkage, three rear hydraulic remotes and a mechanical PTO with 540/540E or 540/1,000 rpm settings support a range of agricultural implements.
