Welcome to J.B. Mertz & Son Inc.

Next Generation Planting has Arrived

Accuracy paired with speed, like you’ve never seen before. That’s the ExactEmerge experience. 10mph planting that offers accurate singulation, population, spacing, and uniform depth so you can maximize your productivity and yield potential. Designed for corn and soybean varieties of all shapes and sizes, ExactEmerge is the row unit to push your profit margins exactly where you want them.


Brush Belt Delivery System

Brush Belt

This patented technology delivers seed to the bottom of the trench at a rearward trajectory that truly matches the ground speed of the planter at any desired population. This gives you precise seed placement with no bounce as can be found in some seed tubes, and no roll in the trench, whether you have corn or high-rate soybeans. Brush bristles gently cradle the seed on all sides with full control to deliver each seed to the bottom of the trench, even in rough planting conditions, so there's no degradation to in-ground spacing accuracy. And a brush belt conditioner at the bottom of the delivery system is self-cleaning to shed any dust from the brush belt.


High Performance Vacuum Meter

Vacuum Meter

Our true pour-and-plant meter lets you use a variety of seed shapes and sizes, all at once, and with no mechanical adjustments – like refuge in the bag. Use whichever seed you prefer without any hesitation or sacrificing of your hybrid selection. Plus, the vacuum meter maintains a target population even over terrain with slopes up to 15°.


Dual Electric Motors

Dual Electric Motors

The ExactEmerge electric drive system is powered by two brushless maintenance-free motors on each row unit that work independently to control the meter and the brush belt – with no synchronization required. Compared to standard brush motors that generate friction and heat build up, our motors run more efficiently and provide longer life. The motors operate off of ground speed to provide accurate target population and speed matching seed delivery.


Seed Sensor

Seed Sensor

Provides every vital bit of information for each seed that travels through the brush belt delivery system: population, seed spacing, seed singulation; it’s all gathered here and then delivered to the new SeedStar HP monitoring system.


Improved Shank

Improved Shank

Faster planting speeds mean more shock load and stress. So we strengthened the row unit shank to withstand additional force and impact without fracturing, regardless of planting conditions. And an enhanced gauge wheel arm provides greater wear life.
