the problem
Worn parallel arms let your row units rock instead of tracking the ground. That means inconsistent planting depth, uneven emergence, and a stand that costs you bushels - and it always shows up right when you can least afford downtime: planting season.
The solution
Carlyle Metals builds direct-fit Agco planter parallel arms from AR400 abrasion-resistant steel - hardened to around 400 Brinell, the same wear-plate steel used in skid-steer buckets and dozer edges. It's built to resist the wear and elongation at the pivots that make row units sloppy - so these arms don't just replace worn parts, they outlast them. Precision laser-cut, CNC machined bushing holes Robotic welded to spec, and made in the USA. In stock and out the door the same day, so you're in the field when it matters.

Harder steel resists abrasion and pivot wear. We anchor on AR400's own hardness - not a claim about what any particular OEM or competitor arm is made of -and back it with the 5-year warranty. If your OEM arms are cast iron, add the toughness angle too: cast can crack under impact; fabricated AR400 won't.

"These arms have planted over 50,000 acres. I wanted to pull them off and check to see if there has been any wear. I was blown away, they hadn't wore at all, not even the bushing."

Frequently Asked Questions
Please reach us at austin@carlylemetals.com if you cannot find an answer to your question.
Agco White parallel arms wear due to repeated row unit movement and load stress. Over time, softer factory materials allow pivot wear and structural flex.
Genesis arms use abrasion-resistant steel to maintain tighter tolerances longer.
Yes. Genesis Agco White Parallel Arms are designed to work with standard OEM-style bushings and hardware. Each arm is precision-machined to maintain proper fit and alignment, allowing straightforward installation without modification to your existing planter.
Signs include:
• Excessive row unit movement
• Uneven planting depth
• Worn pivot holes
Replacing worn arms restores stability.
Genesis arms provide longer structural durability due to stronger steel construction.
Genesis arms improve performance by addressing arm wear directly using stronger steel.
