This wrench is just 3/16" thick.  On most John Deere planters it is not necessary, however on the very newest planters or those whose gauge wheel arms have been replaced with the latest design, this wrench is helpful in adjusting the gauge wheel to the disc opener and holding that adjustment while installing Furrow Brows.  It will be included free with orders of 12 rows or more of "DeereBrow".

Replacement Furrow Brow part for right hand side of the planter row unit, bolt not included

This Furrow Brow row kit is for all John Deere planters 1996 and newer with standard 4.5 inch tires (your tires will typically measure 4.25-4.5 inches).  These planters have a 16mm (looks like 5/8") bolt on the gauge wheel arm pivot.  (Note: If your JD 7200 planter has stub shafts for the gauge wheel arms and 12mm (looks like 1/2") bolts, please order "FurrowDeere", not these!)  Each row kit includes two Furrow Brows (R&L), longer 16mm x 110mm bolts (metric, grade 10.9), plus six bushings to allow for proper alignment over the gauge wheel tire.  Each order of 12 rows or more includes a thin wrench which is helpful in installation on the very latest style of John Deere gauge wheel arms.  All orders include detailed installation instructions.

Coming soon... a Furrow Brow modified slightly to fit planters with Coyote Mfg. gauge wheel arms and standard 4.5 inch gauge wheel tires. Production expected by 3/31/2023.
