Material and Technical Highlights

We don’t cut corners on quality. The TF-285B uses alloy steel for its gears and shafts, treated with carburization and tempering to withstand wear and stress. The housing, made of cast iron, protects the internals from debris and impacts—think rocks or stumps in a field. High-speed ball bearings ensure smooth rotation, cutting down on friction and heat buildup.

Our manufacturing process draws on decades of expertise. From forging to grinding, every step is fine-tuned to meet industry standards. We also apply surface treatments like blackening to resist corrosion, a must for Argentina’s humid summers. The result? A gearbox that’s tough enough for industrial mowing or farmwork, yet precise enough for clean, even cuts.
