Grammer DS 44 Mechanical Suspension Seat in Heavy-Duty PVC with Vario Bracket & Adapter Plate 12096720 (260 mm Gauge) - Part Numbers: 12538610 / G12538610
The Grammer DS 44 mechanical suspension tractor seat (part numbers 12538610 / G12538610) is a complete original equipment and premium replacement seating package supplied complete with the dedicated adapter plate (part number 12096720) configured for a wide 260 mm track gauge. Engineered for open-station platforms, utility tractors, and heavy field machinery with wide chassis mounts, it incorporates a heavy-duty mechanical scissor linkage paired with a high-performance hydraulic shock absorber to isolate the operator's spine from rough terrain shocks and low-frequency vibrations. Its hard-wearing, waterproof, and UV-stabilized heavy-duty PVC upholstery withstands prolonged exposure to rain, field mud, dust, and direct sunlight. Combining the multi-angle adjustable Vario bracket (10°, 16°, 20°, 26°, 36°, 50°) with the 260 mm adapter plate, it ensures a perfectly level, rattle-free, and ergonomic seating position across wide-mount agricultural platforms.
Key Features & Ergonomic Advantages
- Complete Kit with Adapter Plate 12096720: Pre-fitted with a dedicated mounting base plate providing a 260 mm track gauge, allowing direct bolt-on installation onto wide tractor mounting decks without drilling or fabrication.
- Mechanical Suspension with Hydraulic Damper: Scissor suspension mechanism with a 90 mm travel stroke, effectively damping harmful vertical impacts and field oscillations.
- Adjustable Multi-Angle Vario Bracket: Lower mounting bracket configurable to 6 distinct tilt angles (10° / 16° / 20° / 26° / 36° / 50°) to compensate for slanted mudguards or inclined transmission tunnels.
- Stepless Weight Adjustment (50 – 120 kg): Smooth continuous pre-load adjustment via front rotary knob to match the driver's exact body weight, preventing suspension bottoming.
- Fore/Aft Slide Travel (150 mm): 150 mm horizontal slide adjustment on precision guide rails with positive notch engagement for optimal reach to foot pedals and steering wheel.
- Weatherproof & Heavy-Duty PVC Upholstery: Anatomically contoured cold-cured foam encased in heavy-gauge synthetic vinyl, resistant to abrasion, tearing, agrochemicals, and pressure washdowns.
- Comprehensive Accessory Compatibility: Structural design engineered to accommodate optional operator presence safety switches, seatbelts, and integrated seat heating elements.

Installation Advice & Workshop Notes: Before final mounting, position the 12096720 adapter plate on the floor deck to verify alignment with the 260 mm mounting holes. Adjust the Vario bracket to the appropriate angle (10°, 16°, 20°, 26°, 36°, or 50°) to ensure the seat cushion rests perfectly level. Secure the assembly using high-tensile hardware (Grade 8.8 minimum) along with self-locking nuts or spring washers. When adding optional accessories such as an operator presence switch or seat heating, route wire harnesses neatly along the slide rails to avoid pinch points during fore/aft travel (150 mm) or suspension deflection (90 mm). Finally, calibrate the front weight knob to the operator's weight to ensure optimum dynamic ride comfort.
