THE CHALLENGE
Adapting the hydraulic system layout of a 100 HP tractor equipped with a CVT transmission to accommodate the larger transmission package, while keeping the overall vehicle envelope unchanged in order to reuse the existing cab, chassis, and major components.
THE SOLUTION
The auxiliary hydraulic oil reservoir has been separated from the transmission oil reservoir, increasing the front housing capacity from approximately 5–6 liters to 12 liters.
A dedicated cooling circuit has been designed, featuring, a suction-side filter, an oil-to-oil heat exchanger, and a repositioned pressure-side filter. Hydraulic hose routing was optimized using larger-diameter lines to fit within the constrained space imposed by the CVT transmission.
To integrate the heat exchanger, the front cooling module support was extended while preserving full steering articulation and tire compatibility.
RESULTS
- Compatibility with Existing Platform
The CVT transmission was successfully integrated without compromising the original vehicle architecture or requiring major platform changes. - Unchanged Maneuverability Performance
Steering angles and turning radius remained identical to the mechanical transmission version, ensuring the same level of agility. - Preservation of Optional Equipment
Despite the hydraulic system redesign and the use of larger-section hoses, compatibility with existing optional features was fully maintained.
