***New for 2026 is the optional MeterMasterPro version with the added feature in the handle to easily turn the cable drive lock on the John Deere Pro-Shaft drive.***

For years we fought hard to turn seed disk latches.  Our "farmer fix" was to use an adjustable wrench on one of the latch ears and cringe seeing the latch flex expecting it to break.  We took it upon ourselves to invent a better way, the MeterMaster. 

MeterMaster is a simple, yet revolutionary tool, tailor made for all John Deere vacuum planters from MaxEmerge to ExactEmerge, including Precision Planting eSets.  This industry first tool enables effortless locking and unlocking of seed disk latches.  Unlike using an adjustable wrench, MeterMaster captures the entire surface area reducing mechanical stress on the latch and also minimizes farmer fatigue. 

Developed in-house to address a need identified on our own farm, the MeterMaster is precision-manufactured in the United States utilizing high-grade American 304 stainless steel. This material selection ensures exceptional durability for a lifetime investment. As with all our products, the MeterMaster is supported by our comprehensive, no-nonsense warranty, underscoring our commitment to quality and customer satisfaction.
