Aluminum Boom Extensions
John Deere Extensions
Contact us for more info 24/7 at: 512-757-5862

Available for John Deere Models: 4720 (2006 & newer), 4730 & 4830


The design of our aluminum extension was based on the same principle as our booms to allow the breakaways to be longer, as most customers wanted the additional length. So, we have a 21' section and a 8'.5" breakaway. With this configuration, the extensions will require new stainless steel tubing and nozzle bodies. 


  • The extensions can be reused in the event of an upgrade to a new John Deere machine                 (should John Deere change their design a replacement bracket may be required).

  • Modifications can be made to meet either a slightly longer or shorter length of extension.

  • The use of eccentric bushings with two adjustable set screws allow leveling of the outer section.

  • 3-Way Breakaway System

  • 1-Year Limited Manufacturer Warranty

  • Stainless Steel Plumbing: (High & Standard Flow)
