Grammer Compacto Basic S (MSG83/511) Mechanical Suspension Seat in Breathable Fabric - Part Number: 2401289042 / OEM Ref. 1289042
The Grammer Compacto Basic S (model MSG83/511) low-profile mechanical suspension tractor seat in fabric (part number 2401289042, genuine Grammer OEM reference 1289042) is an authentic compact seating assembly (400 mm cushion width) designed specifically for enclosed cabs on vineyard, orchard, alpine, municipal, and narrow-track agricultural tractors. Equipped with a heavy-duty mechanical scissor suspension providing an 80 mm travel stroke, it features an intuitive combined height and weight adjustment system: a rotary slide knob sets 3 distinct seat height levels (total height 627 to 687 mm), while a front-mounted lever with a visual weight indicator window allows drivers to calibrate spring preload directly while seated, ensuring full suspension travel is always maintained. Upholstered in premium breathable, heavy-duty technical fabric, it provides exceptional climate comfort during long working shifts inside enclosed tractor cabs. Featuring an adjustable-tilt backrest, mechanical lumbar support, and a 225–227 mm rail track gauge, it offers universal compatibility across selected models from Case IH, Deutz-Fahr, Fendt, Fiat, Ford, John Deere, Kubota, Lamborghini, Landini, Massey Ferguson, McCormick, Same, and New Holland.
Key Features & Ergonomic Advantages
- Compact Space-Saving Profile (400 mm Width): Engineered specifically for narrow tractor cabs, providing maximum elbow room and unobstructed access to side consoles and hydraulic controls.
- Breathable High-Wear Technical Fabric: Heavy-duty, wear-resistant woven textile upholstery that promotes active air circulation, preventing heat buildup and perspiration during long shifts in enclosed cabs.
- Mechanical Scissor Suspension (80 mm Stroke): Heavy-duty pantograph linkage with hydraulic shock damping to effectively absorb ground shocks and isolate the driver from low-frequency terrain oscillations.
- Combined 3-Stage Height & Direct Weight Adjustment: Height adjustment from 627 to 687 mm via rotary knob, paired with an easy-to-read front-mounted lever for seated weight calibration, ensuring suspension travel is never compromised.
- Integrated Mechanical Lumbar Support & Reclining Backrest: Built-in mechanical lumbar adjustment and continuous backrest angle tilt to ensure correct posture and reduce driver fatigue.
- Extended Fore/Aft Slide Travel (210 mm): Long 210 mm horizontal adjustment on smooth roller rails for optimal distance tuning relative to steering controls and foot pedals.
- Modular Accessory Readiness: Pre-drilled and structurally prepared to accept an adjustable headrest (optional), armrests (optional), fore/aft horizontal isolator (optional), operator presence switch (optional), and integrated seat heating (optional).

Installation Advice & Workshop Notes: Prior to installation, confirm the bolt pattern on the tractor floor pan or mounting console (227 mm rail track gauge). Secure the slide rails firmly using high-tensile hardware (Grade 8.8 minimum) and locking washers. If an operator presence switch or seat heating element is installed, route wiring harnesses to prevent pinching during 210 mm fore/aft sliding or 80 mm suspension travel. After installation, select the desired seat height (3 levels available) using the rotary slide knob, then, while seated, adjust the front weight lever until the indicator window reflects your body weight to ensure the full 80 mm suspension stroke is active. Finally, verify smooth horizontal sliding and set the desired backrest and lumbar contours.
