Commercial vehicle seats – Tractor seats, agricultural tractor seats, commercial vehicle seats similar to Grammer MSG085 and MSG095.

Tractor seats are the ergonomic workplace for drivers of tractors and commercial vehicles. Their primary function is the damping of shocks and vibrations caused by uneven terrain or machine operation. This helps prevent back injuries and fatigue, maintains performance during long working hours, increases safety, and supports a healthy seating posture.

• Seat covers: High-quality fabric or durable PVC artificial leather, resistant to dirt, moisture, and UV.
• Padding: High-density foam materials for comfort and shock absorption.
• Frame & suspension: Steel or aluminum alloys, often powder-coated for corrosion protection.

All materials are designed for durability and robust continuous use.

• Adjustable seat height & tilt
• Weight adjustment: e.g. 50–130 kg (mechanical) or 40–150 kg (pneumatic)
• Horizontal adjustment: e.g. 210 mm in 10 mm increments
• Lumbar adjustment: mechanical or pneumatic
• Armrests/headrest: often removable
• Swivel adapter: integrated, e.g. 20° (optional up to 180°)
• Pneumatic seats: 12 V compressor for height & weight adjustment as well as pneumatic lumbar support

Mechanically suspended (e.g. Harita Terra T5): spring travel approx. 140 mm, weight range 50–130 kg, manual height/weight adjustment, mechanical lumbar support. Options: fabric/PVC covers, short/long backrests, comfort armrests, lap belt, 20° swivel adapter.

Pneumatically suspended (e.g. Harita Terra T6): spring travel approx. 180 mm, weight range 40–150 kg, integrated 12 V compressor for pneumatic height/weight adjustment and pneumatic lumbar support. Add-ons: longitudinal suspension, seat occupancy sensor, comfort-plus armrests, optional low-frequency suspension or external 180° swivel adapter; covers in fabric/PVC and variable backrest lengths.

• Applications: Agricultural tractors/tractors, municipal vehicles & construction machinery, industrial forklifts/commercial vehicles, forestry equipment.
• Stresses: Continuous operation with dust, moisture, temperature fluctuations, and heavy vibrations.
• Design: High durability and reliability despite harsh environments.

• More comfort & less fatigue – improved concentration and safety.
• Spinal protection through effective vibration and shock absorption.
• Robust construction for long service life.
• Individual adjustment creates an ergonomically optimized workplace and increases productivity.

• Regular cleaning (covers) and checking for material wear.
• Suspension inspection for function/wear as well as checking mountings & adjustment elements for secure fit.
• Replace worn padding/components in good time.

The service life of high-quality seats is – depending on use/maintenance – several years up to > 10 years. As a guideline: replacement after approx. 1,000 operating hours or at clear signs of wear to ensure continuous ergonomics & safety protection.

• Vehicle type & installation situation (space, interfaces, swivel console).
• Driver dimensions: height/weight and seating duration.
• Operating conditions: vibrations, weather, dust, moisture.
• Comfort functions: suspension type (mechanical/pneumatic), adjustments (height, tilt, horizontal, lumbar), armrests, headrest, swivel adapter.
• Load capacity & weather protection (material selection, cover).
• Individual consultation for optimal adjustment for health & comfort.
