The company
Three generations keeping the countryside turning
We are a family business serving agroindustry since 1992. Every gearbox that leaves our plant carries the family name on the cover.
We design and manufacture drivetrains for the implements that sustain Mercosur’s production. We work side by side with equipment manufacturers and with the farmer who needs a spare part today, not next week.

Process
How we build
CASTING & MACHINING
Iron that outlasts the season
Grey cast iron housings and machined bevel gears with controlled tolerances, built for real field conditions: dirt, load and hours.
TESTING
Every model, tested
Gear tooth contact, seal tightness and oil-bath operation are verified before dispatch.
SUPPORT
Spare parts & after-sales
We ship nationwide, and our gearboxes also work across Mercosur. Spare parts for the entire EV series and technical support directly from the factory.
Read our Quality policy.
Do you build implements? Let’s be your drivetrain supplier.
We develop build-to-print gearboxes for OEMs, with delivery continuity and factory pricing. Our drivetrains already reach Mercosur.
Purchasing & shipping
Frequently asked questions
01How do I request a quote?
Via WhatsApp: use the Quote button on any product (it opens the chat with the model preloaded) or message us directly. We reply with price and lead time the same day.
02What payment methods do you accept?
For customers in Argentina: bank transfer (details are sent with the quote). For exports, payment terms are agreed as part of the quote.
03Do you ship?
Within Argentina we ship nationwide by carrier. We also serve Mercosur customers — shipping arrangements are agreed for each order.
04Who pays the freight?
Within Argentina, we deliver your order to the carrier (in Firmat or Rosario) at no charge; freight from there to destination is paid by the customer. For exports, ask us.
05I don’t know which model I need — what do I do?
Send us a WhatsApp photo of the gearbox you have (even if broken), tell us which machine it goes on and, if possible, the shaft dimensions. We’ll identify it and send you a quote.
06Do you sell individual spare parts?
Yes, for the entire EV series: gears, shafts, cast housings and more. Send a photo of the part or its dimensions (shafts: length and diameter; gears: tooth count and diameters) and we’ll quote it. If your gearbox is many years old, include a photo too: some older models were updated over time and we’ll check the part matches.
07Do the gearboxes come filled with oil?
No — they ship without oil. Before start-up, fill with the correct oil type and quantity for each model: ask us on WhatsApp and we’ll tell you.
