The range
Gear units by implement family
Every unit is designed around the implement it drives: ratio, module, housing and shaft interface. Use the selector to filter by application, PTO power and spline type.

Engineered for the field
Built to survive the seasons, not just the spec sheet
Designed for efficient power transmission, reliable performance and long service life under demanding field conditions.
01
Quenched gears and shafts
Gears and shafts are quenched to achieve high surface hardness where the load is carried, with a tough core that resists shock from stones and root mass.
02
Spheroidal graphite iron housings
Low noise and low vibration. Spheroidal graphite iron gives high material durability and long service life, and damps the drivetrain rather than amplifying it.
03
Quality seals and bearings
High quality oil seals and bearings keep dust and field water out and lubricant in. Those are the two failure modes that actually strand an implement.
04
Pre-delivery inspection
Every gearbox is run on a custom testing rig before despatch, so what leaves Dhuri has already turned under load.
Where they end up
Trusted by leading OEM manufacturers
Our gear units operate across domestic and international markets, including government and institutional projects, in rotary tillers, straw reapers, harrows, mulchers, balers, spreaders, diggers and combine harvesters.
