Needle Protector 700129647 Replacement Knotter Spare Part Fits Massey Ferguson MF2270XD Large Square Baler

The needle protector 700129647 is the guard plate that stands between the knotter needles and the moving plunger head on Massey Ferguson and Challenger large square balers. During every compression stroke the needles rise through the bale chamber to hand the twine to the knotters, and this shield keeps chaff, crop residue and stray bale material away from that path so the needles return cleanly to their park position.

Because the protector sits in the dirtiest part of the knotter frame, it is one of the first sheet metal parts to wear thin, bend or crack after a few seasons of hay and straw work. Replacing a distorted protector with a straight, correctly formed one restores needle alignment, removes the scraping noise that operators hear at the top of the stroke, and prevents the expensive needle breakage that follows when a bent guard deflects the needle into the knotter frame.

• Stamp formed from heavy gauge mild steel, dimensionally matched to the original AGCO profile for drop in fitment.
• Protects knotter needles and twine discs from chaff build up, stone damage and crop wrapping during the compression stroke.
• Precision punched mounting holes align with the existing knotter frame bolts, no drilling or slotting required.
• Bevelled lead in edges guide the needles smoothly and reduce the risk of needle deflection at high plunger speed.
• Supplied clean and ready to install, compatible with both twine and net wrap configurations on the same knotter frame.
• Painted finish resists corrosion through humid storage and long idle periods between harvest seasons.

This protector is used on Massey Ferguson MF 2150, MF 2170, MF 2170XD, MF 2270, MF 2270XD, MF 2250 and MF 2290 balers, and on Challenger LB34BXD, 2270XD, CH LB34, CH LB34B and CH LB44B models. It suits contractors running several machines of the same family, dealers keeping fast moving knotter consumables on the shelf, and workshops that rebuild knotter frames after a needle failure. Because the same part serves both brands, one stock line covers a mixed fleet.

Every protector is wrapped in rust preventive paper, packed in a carton with a part number label matching the AGCO reference, and consolidated on a pallet for container loading. Cartons are sized so that small orders can ship by air express without dimensional weight penalties, and mixed pallets can combine protectors with knotter gears, anvils and needles from the same order.

Please confirm your machine model and serial range when ordering, since late production balers occasionally use a revised knotter frame. We keep regular stock of 700129647 and can ship small trial quantities so you can verify fitment before committing to a container load.
