FEATURES
Powerful V-twin engine features full-pressure lubrication for dependability and long life
A 22-hp (16.4-kW) V-twin engine has plenty of power and torque to handle tough mowing, mulching, and bagging:
- V-twin cylinder design for greater torque, lower vibration, and improved sound quality
- Electronic ignition for fast starts
- Spring-return feature to ensure the operator does not mistakenly leave the throttle lever in the choke position
- Cast-iron cylinder liners for longer engine life
- Overhead valves for excellent power and fuel economy
- Full-pressure lubrication and oil filter for cleaner oil, prolonging engine life and extending the time between oil changes
- More effective when operating the tractor on an incline
- The capacity is 2.4 U.S. gal. (9.1Â L).
- The fuel filler opening is conveniently located under the seat.
- Filling the tank without spilling is easy.
- A tethered fuel tank cap is more convenient.
- The sealed fuel cap helps keep vapors inside the tank.
John Deere Easy Change™ 30-second oil change system
The John Deere Easy Change 30-second oil change system makes changing the engine oil easy, quick, and clean. Changing the oil is as easy as twisting on a new oil-filled filter. Oil does not need to be drained from the engine.
The John Deere Easy Change filter is an additional engine oil reservoir. Changing the filter removes the captured contaminants and replaces about 0.8 qt (0.76 L) of engine oil.
The functionality does not stop with ease of use. The Easy Change oil system has several meaningful benefits over the traditional oil filter system of the 100 Series:
- A synthetic filter material is used for more predictable filtering and longer life.
- Filtering capacity is greater than with a standard oil filter.
- More filter surface area
- More oil flow capacity
- The system has 40 percent more oil volume.
- The oil and engine run cooler.
- The oil filter valve closes whenever the engine stops, so filtered particles are captured and cannot drain back into the engine.
- The risk of spilling during oil service is greatly reduced.
- Waste oil (and new oil production) is reduced by over 1,000,000 lb (453,592.4 kg) per tractor production year.
- This system is not a compromise to just make oil changes easier—these engines pass the same John Deere expectations and rigorous testing as always.
Partly due to these improvements, it is not necessary to remove and dispose of all the oil in the engine during service.
Eye-catching styling built upon a dependable full-length welded steel frame
Light emitting diode (LED) headlights complement modern styling
The 100 Series Lawn Tractors are equipped with LED headlights that:
- Complement the tractor’s modern styling
- Use less power and are far more durable than incandescent light bulbs
- Provide a natural light quality that increases visibility in low-light conditions
- Light the field of view evenly
Hood will not rust or dent
The hood used on 100 Series Lawn Tractors is made using the mold-in color process. The hood reduces sound, will not rust or dent, and provides resistance to UV light. Side openings let in plenty of cooling air while keeping the sound level low.
Reliable full-length welded steel frame
The solid one-piece frame is constructed of 12-gauge, 0.105-in. (2.66-mm) steel:
- Full-length, robotically welded frame design has high-strength steel rails for added strength and long life.
- One-piece, steel fender deck is bolted to the frame.
The front axle is constructed of solid cast iron that will not bend:
- Automotive-like steering system with sector and pinion steering gears and single drag link with a tie rod provides a very strong, low-effort, and tight-turning system.
- Three grease fittings, on both steering spindles and center pivot, allow for regular lubrication to help maintain easy steering and minimize wear.
- Large, 0.75-in. (1.9-cm) diameter wheel spindles provide excellent durability.
Snow removal is a strength of lawn tractors
An advantage of lawn tractors is their ability to use equipment for snow removal. Lawn tractor owners can add a John Deere snow blower or front blade to make quick work of moving snow whenever the need arises. Weather enclosure and tire-chain attachments add comfort and performance.
Equipment available for snow removal includes:
- 44-in. (112-cm) Snow Blower
- 46-in. (117-cm) Front Blade
- Tire chains or TerraGrip traction belts
- Weather enclosure
- Weights
Hydrostatic transmission gives an infinite choice of ground speeds
A Kanzaki® Tuff Torq® hydrostatic transmission gives an infinite choice of speeds and makes changing the direction of travel easy. Side-by-side foot pedals control the speed and direction of travel:
- Automotive-type accelerator controls ensure easy operation.
- Operator can change direction without lifting foot off the platform.
- Large pedal surface gives superior operator comfort.
