Current U.S. Massey Ferguson MF 4709 from the October 2025 AGCO standard-features sheet, the current MF 4700 page and the 2024 Global Series brochure. 12F/12R power shuttle (24F/24R Dyna-2 optional), 2WD or 4WD. Base weight 7,478–8,644 lb (2WD ROPS to 4WD cab).
The February 2024 Global Series brochure lists 5,291 lb (2,400 kg) full stroke 24 inches behind the ball ends for the MF 4700; the October 2025 AGCO sheet lists 4,850 lb (2,200 kg) at 24 inches, and the current page says lift capacity ranges “from 4,850”.
The newer sheet’s 4,850 lb is recorded, which the current page supports. Every attachment here weighs far less, so no fit result changes.
