Harvest More With BranValt Mad Concaves
BranValt designs and manufactures a unique set of after-market concaves for a variety of combines and crop types to increase your profits, maximize your combine capacity, save you time, and improve safety during the critical harvest season.
Harvest More Profit
✔ LOWER DOCKAGE: Our unique concave designs offer more threshing precision to reduce cracked and damaged grain and lower the amount of foreign material in the tank.
✔ PRECISION THRESHING: Get your grain out of the head and into the hopper faster for lower rotor loss and higher returns.
Harvest More Time
✔ UNBEATABLE CAPACITY: By enabling more grain through the concaves faster with lower losses and a better sample, you’ll be able to increase throughput and pick up ground speed. Save time and fuel while achieving greater overall harvest efficiency.
✔ FAST & EASY TO CHANGE DESIGN UNLIKE ANY OTHER: because one concave for all crops doesn’t achieve top results! Our modular frame design allows you to quickly swap out smaller, lighter inserts in minutes instead of messing around with traditional heavy concaves, wire pulling or cover plates. This saves you time and gives you more flexibility to change out concaves for different crops or conditions.
Harvest More Safely
✔ LIGHTER CONCAVES: Traditional concaves are heavy and can take hours to deal with between changing crops and conditions. Our split frame design makes it easier to swap out lighter inserts, lowering the risk of harm or injury for farmers and operators while saving time in the field.
Harvest More Confidently
✔ ALWAYS EXTENDED WEAR: Made with AR-200 (abrasion resistant) steel, our concaves are built to last longer than other concaves on the market. This lets you cover more acres for the dollars invests.
✔ FIELD-TESTED: ...By real farmers in real fields in a variety of crops and conditions globally. They’ve reported lower losses, higher grain quality, increased capacity and the ability to swap inserts in 15 minutes.
