iMatch quick-hitch

One of the greatest concerns for operators involves difficulty in attaching tractor implements. John Deere has addressed this issue with the iMatch quick-hitch sytem.

The iMatch quick-hitch provides easy hookup and a guaranteed fit for all Category 1 implements designed to meet the ASAE Category 1 Standard S278.6 for quick-attach hitches.

All implements require a set of bushings in order for the attachment to fit and work properly with the iMatch quick-hitch. One set of bushings comes with the iMatch quick-hitch. Additional bushings are available from a John Deere dealer.
