8A Bumper Attachment – 7000/8000 Series SPFH

Intended Use

The 8A is intended to be used to provide a bumper as well as ballast for the SPFH to allow for ease of installation of larger headers.  The weight rack section of the bumper can be removed and the bumper plate re-installed to provide protection for the back of the machine.


When using the weight rack, the factory weights are not needed on the 8000 SPFH.  The bumper provides room for traditional tractor suitcase weights for all of the ballast needed.

Product Highlights

  • Overall package allows for more cost-effective ballast solution than factory weights and a custom-built bumper for each customer.
  • Modular design allows for removal of the weight rack and reinstallation of the bumper when using hay pickups.
    • Removing extra ballast reduces compaction in hay fields and increases yield.
    • Removing extra ballast improves fuel efficiency, especially in transport.
    • Removing extra ballast during harvesting improves harvest capacity when the engine is under full load.
  • Fork lift pockets and lift point locations are provided for ease of removal of weight rack and bumper with forks or lift chains for ease of reconfiguration when switching between hay pickups and corn heads.
  • Adjustable bumper height allows for ground clearance from approximately 12” to 21”, depending on tire options of the SPFH.
  • Tow bar mount at rear of unit for ease of connection of tow straps and/or chains.
  • A pintle hitch is provided for quick chain and strap attachment.  It is NOT INTENDED to be used for pulling trailers.
  • Multiple mounting locations for hitch plate of SPFH.  Important:  Always follow towing recommendations of the SPFH.  Refer to John Deere 8000-Series SPFH Operator Manual for more information.
  • Weight rack fits traditional John Deere tractor suitcase weights.
  • Clearance is provided for access to rear SCV and electrical connection of SPFH for auxiliary functions.

 MY2017 Changes

For MY2017, a pintle hitch is added to the rear of the bumper for ease of attachment for chains and straps.  It is NOT INTENDED to be used for pulling trailers.  Additional pads are also added for increased coverage of the rear of the bumper when lowering the adjustable plates.

2018 Changes

For MY2018, the bundle is changed to fit the 7000-Series as well as the 8000-Series SPFH.

If installing on a 7000-Series equipped WITH an inoculant / water tank under the rear of the machine, also order quantity 4 of rear weight plates (Z48791).  Ballast the machine to recommendations in the operator manual of the self-propelled forage harvester accounting for the weight of the attachment.

Ballasting Recommendations

IMPORTANT: Proper ballasting will keep efficiency of the four-wheel drive system and steering function when braking.

IMPORTANT: Always put same amount of weight plates inside left and right hand weight carrier when using the Standard Weight Rack.  Refer to 8000 Series SPFH Operator Manual for information regarding weight plate installation if a weight rack is not needed.

IMPORTANT: Do not overload rear tires, especially when header is removed.

IMPORTANT: Special field conditions may require higher ballasting to keep efficiency of the four-wheel drive system and steering function.

Depending on machine/header type configurations, ballasting differs. To properly ballast the machine, ALWAYS refer to the relevant ballasting chart, then install required amount of weight.
