Upper Hay Dog 700141445 Baler Feeder Fork Replacement Fits Massey Ferguson MF2270 & Challenger LB34BXD

The upper hay dog 700141445 is the pivoting tooth that grips the crop mat on the feed side of a Massey Ferguson or Challenger large square baler. Working with its lower and side partners, it holds the hay or straw steady while the plunger compresses the charge, releasing only when the stuffer returns for the next flake.

Teeth that have rounded off or bent no longer bite, and the result is a soft or uneven flake, crop pulled back into the feed chamber and a bale that varies in density from one end to the other. Because the tooth works in an abrasive stream of dust and grit, a set of dogs is a normal seasonal service item rather than a repair that indicates abuse.

• Hardened tooth tip retains a sharp gripping edge through abrasive hay, straw and silage bale work.
• Forged pivot eye sized to the original pin so the dog swings freely without slop or binding.
• Correct tooth angle restored, which brings back consistent flake weight and bale density control.
• Thick shank section resists bending if a stone or foreign object passes through the feed chamber.
• Interchangeable with the original AGCO dog, allowing replacement without modifying the feeder frame.
• Clean painted finish keeps the pivot free during storage and prevents rust seizure between seasons.

Fits Massey Ferguson MF 2150, MF 2170, MF 2170XD, MF 2250, MF 2270, MF 2270XD and MF 2290 balers and Challenger LB34BXD, 2270XD, CH LB34B and CH LB44B models. Operators normally renew the upper, side and base dogs as a set, because they wear together in the same abrasive environment and a single new tooth beside two worn ones quickly loses its advantage.

Each dog is wrapped, boxed and labelled with the AGCO part number, then palletised with matching feeder parts for export. Set quantities of upper, side and base dogs can be combined in one carton on request, which simplifies stock keeping for dealers and reduces freight cost per piece.

Let us know whether you run hay, straw or silage bales, as crop type affects how quickly the teeth round off. We can supply the complete set of feeder dogs with pivot pins and hardware so the feeder chamber is renewed in a single pass.
