Yetter Knife Improvements Boost Efficiency

Longer life because of design changes allows for more acres covered before replacement

Published on: Jul 25, 2011

The new 2987 Series knife offered on the Yetter 2987 Magnum fertilizer knife is now made of cast material and carries a tungsten carbide edge for wear resistance through many acres of use.

The knife wraps around the fertilizer tube for better wear protection from the soil and adds significantly to productive knife life. The Magnum knife components can be replaced one at a time to reduce the cost of replacing the entire unit, and the new model is spring loaded to allow the knife to be self-adjusting.

Also, the single-disc design of the 2987 Magnum has a lower draft requirement than many conventional fertilizer application tools and reduces fuel costs. Other key features of the unit include a spring-loaded closer wheel and wiper wheel.

Yetters new "wrap around" knife is cast construction and fefatures a tungsten carbide edge for long hours in the field at productive speeds.
