Велес-Агро ГРС 3.

A robust workhorse for deep soil tillage

When you take the GRS-3 out into the field, it immediately becomes clear that the engineers at Veles-Agro prioritized simplicity and structural integrity. This subsoiler doesn't try to be an overcomplicated piece of tech; it does exactly what it's meant to do — destroys the hardpan layer. After passing with this unit, moisture infiltrates the soil efficiently, and crop root systems can finally breathe. For the operator, this means predictable equipment performance without unnecessary stress.

Operational experience and maintenance

The unit requires a solid 150–180 horsepower. If you underload it or attempt to work in overly wet conditions, you’ll just waste fuel without any real benefit. However, on dry, heavy chernozem, the GRS-3 performs admirably. Here are a few key points for an owner:

• Shank protection. The shear bolt protection system is a classic. It’s cheap, reliable, and practical: if you hit a stone, the bolt snaps, and you can replace it in five minutes to keep working. The frame is robust, and the welding quality holds up well after several seasons without signs of metal fatigue.
• Depth adjustment. The adjustment mechanism is straightforward, though it needs regular lubrication to prevent dust from seizing the threads. The rear roller does a great job of breaking down large clods, which often saves an extra pass with a disc harrow.
• Repairability. One of the biggest advantages of Veles-Agro is the availability of spare parts; you aren't waiting on international shipping for basic components. The steel is easy to weld if a serious accidental hit occurs.

While the fuel consumption is significant during deep tillage, it is justified by the yield improvement. The main thing is to keep an eye on the working components. While hard-facing the chisels extends their lifespan, they will naturally wear down in abrasive soils. Overall, the GRS-3 is a piece of machinery that doesn’t require an engineering degree to maintain, making it a reliable partner for any farming operation.
