John Deere S100 42 in. 17.5 HP GAS Hydrostatic Riding Lawn Tractor

✅ Key Specifications

🔧 Performance & Engine Details

• Engine Features:

  • Overhead valve (OHV) design for better fuel economy and torque

  • Cast-iron cylinder liner for durability

  • Full-pressure lubrication and replaceable oil filter extend engine life

  • Anti-vibration system for smoother operation

  • Electronic ignition for quick starts

• No-tools oil drain valve simplifies maintenance and minimizes mess.

📌 Note: Full-pressure lubrication is particularly important for sloped terrain, reducing the risk of oil starvation compared to splash-lubricated engines.

Frame made of full-length welded steel for reliability

🛠️ Build Quality

• The solid 12-gauge steel frame and cast-iron front axle provide structural integrity and longevity.

• Robotically welded frame and steel fender deck increase resistance to vibration and wear.

🔍 According to John Deere, this solid frame design enhances ride quality and reduces chassis flex during use.

⚙️ Hydrostatic Transmis

• Dual-pedal controls (forward and reverse) enable smooth, infinitely variable speed adjustment without shifting gears.

• Suitable for users who prefer intuitive foot pedal operation, similar to automatic cars.

Insight: Hydrostatic transmissions are low-maintenance and ideal for residential users needing frequent speed adjustments around obstacles like trees or flower beds.

🌱 Mowing Deck & Cutting Performance

• 42” Edge™ mower deck is stamped steel, ideal for lawns up to 1.5–2 acres.

• Spring-assisted lever allows easy deck height adjustment.

• Compatible with optional mulch kit and rear bagger (sold separately).

• Blades engage via a manual PTO lever.

💡 Tip: The stamped deck is lighter and better for smoother lawns, while fabricated decks (used in commercial mowers) offer more rugged durability on rough terrain.
