At FIMIC Implement, we don’t just sell parts - we offer lasting solutions that keep your equipment running smoothly in even the toughest working conditions.

Our gearbox collection is specifically curated for farmers, landowners, and implement dealers who demand durability, precision, and performance. Whether you're operating a rotary cutter, tiller, or post-hole digger, each compatible gearbox we offer is engineered to meet or equal to OEM standards. 

Every model is inspected for shaft integrity, housing durability, and gear alignment, and is compatible with popular tractor and implement brands, such as John Deere, Howse, Bush Hog, Omni, or others. We’re happy to help you find the right match.

When a gearbox fails, downtime costs money. That’s why FIMIC Implement stands behind every unit with reliable customer support and proven replacement options. Whether you're repairing a well-worn implement or building a new setup from the ground up, we’ll ensure you have the right gearbox every time.
