Why This 7700 TT RISO Stands Out.
2021 CLAAS LEXION 7700 TT RISO
- Track Mobility for Challenging Conditions: Terra Trac undercarriage grants improved traction, lower ground compaction, and better performance in softer soils or wet fields compared to wheeled units.
- High Power & Rotary Efficiency: With over 540 HP, it can handle high-yield crops and challenging harvest loads with ease.
- RISO Module Capability: The “RISO” configuration enables better performance in rice or paddy conditions or similar crop types requiring specialized harvesting modules.
- Proven Specifications & Support: Backed by CLAAS’s LEXION 7000 series design and service networks.
- Balanced Tank / Throughput: The ~12,500 L grain tank gives a good balance between capacity and unload cycles.
Typical Use Cases & Suitable Environments.
2021 CLAAS LEXION 7700 TT RISO
- Large grain / paddy / rice operations needing high throughput and specialized modules (RISO) for sensitive crops.
- Fields with varying moisture, soft terrain, or uneven ground where tracks help maintain traction.
- Operators who want both high capacity and modern combine features (autonomy, sensors, yield mapping).
- Upgrading from conventional combines to track + rotary systems for better performance in tough seasons.
Inspection & Pre-Purchase Checklist.
2021 CLAAS LEXION 7700 TT RISO
- Validate engine / rotor / drum hours with service logs and verification. The listing gives ~997 / 723 hours.
- Inspect the Terra Trac tracks / modules: track belts, lugs, idlers, alignment, wear, tension.
- Examine the RISO module and harvesting attachments: proper mounting, wear parts, drive linkage, sensitivity for crop type.
- Check rotor / drum, concaves, vanes, bearings, alignment, structural integrity.
- Inspect grain tank, unload system (auger, seals, extension), and inspect for leaks, wear or fatigue.
- Test header / cutter elements: knife condition, reel / draper operation, alignment, hydraulic / drive system.
- Check structural frame, feeder house, welds, fatigue zones, especially near track mounting.
- Inspect electronics, sensor systems, software modules (yield mapping, auto steer, RISO controls).
- Hydraulic & fluid systems: hoses, leaks, pumps, cooling system, filtration.
- Tires (if rear wheels or auxiliary wheels), rims, matching sets, tread.
