John Deere® Compatible Stainless Steel Chopper Floor (70 Series)
Reinforce your residue management system with this premium stainless steel chopper floor. Specifically engineered for John Deere® 70 Series STS combine harvesters, this high-performance housing panel is the professional solution for repairing worn components in the primary straw chopper discharge zone.
Manufactured by XTD Engineering, this floor is constructed from heavy-duty stainless steel to provide superior abrasion resistance under the high-velocity impact of chopped straw, husks, and dust. Unlike standard carbon steel floors that suffer from accelerated wear and structural thinning, this extended wear stainless upgrade maintains a slick, low-friction profile. This strategic refurbishment keeps your residue system in top condition, providing a significantly longer service life.

Expert Maintenance Review
The chopper floor takes immense punishment from high-speed residue flow, particularly when harvesting abrasive crops or operating in harsh paddock conditions. Standard painted steel panels quickly wear thin, leading to holes that allow straw to escape into the rear frame. We recommend inspecting the chopper housing lining for "paper-thin" sections during every preventative maintenance check to identify worn components before catastrophic structural failure occurs.
Upgrading to this high-performance stainless steel floor is a strategic choice to save money on repetitive factory panel replacements. The high-density surface prevents material drag and resists the seasonal pitting that leads to crop sticking, ensuring your harvester remains in top condition for a longer service life.
Installation Tip: Check the Chopper Blades
When replacing the AH218187 chopper floor, always take the time to inspect your chopper blades and hammer pins for wear or imbalance. Out-of-balance blades create severe harmonic vibration that can fatigue any new high-strength panel. Ensuring a perfectly balanced rotor works in tandem with this stainless floor to guarantee smooth operational performance.
