Grammer Compacto Basic S (MSG83/511) Mechanical Suspension Seat in Heavy-Duty PVC - Part Number: 2401081364 / OEM Ref. 1081364
The Grammer Compacto Basic S (model MSG83/511) low-profile mechanical suspension tractor seat (part number 2401081364, genuine Grammer OEM reference 1081364) is an authentic compact seating assembly (400 mm cushion width) designed specifically for 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 the spring preload directly while seated, ensuring the full suspension stroke is always maintained. Upholstered in weather-resistant, heavy-duty waterproof PVC (vinyl), it withstands harsh exposure to sun, rain, mud, and power washing. Featuring an adjustable-tilt backrest, mechanical lumbar support, and a 225–227 mm rail track gauge, it provides 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 cab enclosures and tight open-station platforms, maximizing arm clearance and side control accessibility.
- Mechanical Scissor Suspension (80 mm Stroke): Calibrated pantograph mechanism designed to isolate the driver's spine from harsh ground impacts and intense vibrations.

- Integrated Mechanical Lumbar Support & Reclining Backrest: Adjustable lumbar contouring with variable backrest angle inclination to provide continuous spinal support and alleviate fatigue during long operating shifts.
- Extended Fore/Aft Slide Travel (210 mm): Long 210 mm horizontal adjustment on precision ball-bearing guide rails to match drivers of all statures with optimum pedal and steering distance.
- Heavy-Duty Waterproof PVC Upholstery: High-resilience synthetic vinyl resistant to UV radiation, dirt, mud, grease, and high-pressure water jets, perfect for open-station machines.

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 is specified, install the switch into the cushion base before final bolt torquing and connect the wiring harness to the tractor's safety circuit. 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 210 mm fore/aft sliding action and adjust the backrest recline angle to the preferred driving posture.
