With the seemingly unending trend towards bigger, heavier bits of ag kit, it’s unusual when something comes along that’s smaller and more dainty. Perhaps dainty isn’t quite the word when it comes to  olmer’s Terra Variant, but the latest model, the 435, is a lighter weight machine than what’s gone before. According to the German firm, it’s been developed specifically for those wanting to make applications of slurry and digestate to crops early in the spring when the soil is still damp and delicate.
