Grammer DS 44 / 1B Mechanical Suspension Seat in Heavy-Duty PVC with Vario Bracket - Part Numbers: 2052165 / G2052165
The Grammer DS 44 / 1B mechanical suspension tractor seat (part numbers 2052165 / G2052165) is an authentic OEM-grade ergonomic seating assembly engineered for open-station platforms, orchard/vineyard machinery, and standard cab agricultural tractors. Featuring a heavy-duty mechanical scissor linkage paired with a high-performance hydraulic shock absorber, it provides dependable dampening of low-frequency vibrations and severe terrain shocks. Upholstered in weather-resistant, heavy-duty waterproof PVC (vinyl), it withstands continuous exposure to sun, rain, mud, and dust. The integrated Vario bracket permits multi-angle base inclination adjustments (10°, 16°, 20°, 26°, 36°, 50°), allowing seamless horizontal alignment on inclined mudguards or angled platform mounts. It delivers direct compatibility across leading agricultural tractor brands matching the 187 mm track width: Case IH, Deutz-Fahr, Fendt, Fiat, John Deere, Lamborghini, Landini, Lindner, Massey Ferguson, New Holland, and Same.
Key Features & Ergonomic Advantages
- Mechanical Suspension with Hydraulic Damper: Heavy-duty scissor-action suspension with a 90 mm travel stroke, actively isolating the operator's spine from rough ground vibrations and harmful impacts.
- Adjustable Vario Multi-Angle Bracket: Heavy-gauge steel mounting base with 6 selectable mounting angles (10° / 16° / 20° / 26° / 36° / 50°), ensuring horizontal seating posture even on tilted mudguard consoles.
- Stepless Weight Adjustment (50 – 120 kg): Precision front adjustment knob allows continuous tuning to match individual driver weights, optimizing damping dynamics and preventing suspension bottoming.
- Smooth Fore/Aft Slide Travel: 150 mm of horizontal adjustment on dual ball-bearing slide rails with positive lock notches, ensuring ideal positioning relative to pedals and steering controls.
- Weatherproof & High-Wear PVC Upholstery: Anatomically contoured cold-cured polyurethane padding encased in heavy-duty vinyl PVC, resistant to UV degradation, tearing, hydraulic fluid splashes, and washdowns.
- Safety System Integration Ready: Pre-drilled and designed to accept an optional operator presence seat switch and static or retractable lap seatbelts.

Installation Advice & Workshop Notes: Prior to installation, inspect the tractor chassis baseplate and set the Vario bracket to the appropriate angle (choose among 10°, 16°, 20°, 26°, 36°, or 50°) so the seat cushion rests perfectly level. Secure the slide rails (187 mm track gauge) using high-tensile hardware (Grade 8.8 minimum with locking washers). If an operator presence switch is specified, install the switch into the cushion pocket and connect the safety harness before completing final bolt torquing. After installation, adjust the front weight pre-load knob to the operator's actual weight (50–120 kg) and ensure that both the 150 mm fore/aft slide and the 90 mm suspension stroke operate smoothly without contacting levers, fenders, or cabin bulkheads.
