John Deere 170 Lawnmower: A Closer Look

While the John Deere 175 lawnmower often takes centre stage, its close sibling, the John Deere 170, deserves its own moment in the sun. As a variant produced during the 175's production run, the 170 offers a distinct mechanical experience for those who appreciate simplicity and robust design. Manufactured in the renowned Horicon, Wisconsin facility – a cornerstone of John Deere's outdoor power equipment production – both models benefited from the logistical advantages of this central US location, facilitating distribution across North America.

Understanding the John Deere 170

The primary distinction that sets the John Deere 170 apart from its 175 counterpart is its transmission system. Unlike the 175, which featured a sophisticated hydrostatic transmission, the 170 was equipped with a gear drive transmission. This choice appeals to a different segment of the market, offering a more direct and potentially more durable mechanical connection between the engine and the cutting deck or drive wheels, depending on the specific configuration. This type of transmission often requires a more deliberate shifting process, akin to a manual gearbox in a car, providing a hands-on feel to operating the machine.

Engine Specifications: The Heart of the Operation

The John Deere 170 shares its powerplant with the 175 model. This is a 0.422-litre, single-cylinder Kawasaki engine. Known for their reliability and robust performance in outdoor power equipment, Kawasaki engines are a hallmark of quality. This particular unit is naturally aspirated, meaning it relies on atmospheric pressure to fill the cylinders, and it produces a healthy 14 horsepower (hp). This power is intelligently utilised to drive both the rotary mower deck, responsible for cutting the grass, and the drive wheels, propelling the machine across the lawn. The engine employs an efficient air-cooling system to manage operating temperatures, crucial for sustained performance during demanding tasks. For air intake, it uses a dry-type air filter system, augmented by a foam pre-cleaning element. This dual-stage filtration is designed to capture even fine dust particles, ensuring the engine breathes clean air and prolongs its lifespan. Maintaining the correct oil level is paramount for proper lubrication; the engine requires 1.4 litres of oil to operate smoothly and prevent internal wear.

Transmission Differences: Gear Drive vs. Hydrostatic

The choice between a gear drive and a hydrostatic transmission is a significant one for any rider mower. While the John Deere 175 offered the convenience and smooth acceleration of an Eaton hydrostatic transmission, allowing for seamless speed adjustments up to 8 kph (5 mph), the 170's gear drive transmission presents a different operational paradigm. A gear drive system typically involves a set of gears that are engaged or disengaged by the operator, often via a lever or pedal, to select different speed ranges or forward/reverse gears. This can result in a more mechanical 'feel' and may be perceived as more robust by some users, particularly in environments where extreme conditions might stress a hydrostatic system. The operational simplicity of a gear drive can also be an advantage, with fewer complex internal components to potentially fail.

Weight and Dimensions: Built to Last

Regardless of its transmission type, the John Deere 170, like its 175 counterpart, is a solidly built machine. It tips the scales at approximately 274 kg (605 lbs). This substantial weight contributes to its stability and ability to handle uneven terrain. In terms of dimensions, it measures around 1.65 metres (65 inches) in length when unadorned with any attachments. This size makes it a capable machine for medium to large residential lawns, offering a good balance between manoeuvrability and cutting width.

Attachments and Versatility

The versatility of any lawnmower is often enhanced by the availability of attachments. During its production period, the John Deere 175 was offered with a 6.5 bushel bagger attachment, allowing for efficient collection of grass clippings. It's reasonable to assume that the 170, being a variant, would have been compatible with similar attachments, including bagging systems, mulch kits, and potentially even snow blowers or aerators, depending on the specific power take-off (PTO) capabilities. When using heavy rear-mounted attachments, such as a full grass bagger or a snow blower, it's common practice and advisable to use front weights. These weights help to counterbalance the load, improving traction and steering control, and preventing the front of the mower from becoming too light.

The Horicon Legacy

The fact that both the 170 and 175 models were produced in Horicon, Wisconsin, speaks volumes about John Deere's commitment to manufacturing excellence. Horicon has been a central hub for John Deere's lawn and garden tractor production for decades. This facility is known for its skilled workforce and advanced manufacturing processes, ensuring that each machine leaving the plant meets the high standards expected of the John Deere brand. The geographical centrality of Wisconsin also played a significant role in the efficient distribution of these mowers to dealerships across the United States and Canada.

Production Run and Variants

The production run for the John Deere 175, and by extension its variant the 170, spanned a relatively short period, from 1987 to 1990. This three-year window saw the evolution of these models and the introduction of the gear-drive 170. While specific production numbers for the 170 are not widely published, its existence as a distinct model highlights John Deere's strategy of offering variations to cater to different customer preferences and price points within the same model family.

Maintenance Considerations for the John Deere 170

Maintaining a John Deere 170, with its gear drive transmission, involves regular checks and servicing to ensure longevity and optimal performance. Key maintenance points include:

• Engine Oil: Regular checks of the 1.4-litre oil capacity and timely oil changes according to the service manual are crucial. Using the correct grade of oil is also important.
• Air Filter: Cleaning or replacing the dry-type air filter and its foam pre-cleaner element should be done regularly, especially in dusty conditions, to ensure the Kawasaki engine receives clean air.
• Gearbox Lubrication: The gear drive transmission will have specific lubrication requirements, which may involve checking and topping up or changing gearbox oil at recommended intervals. Consult the owner's manual for the correct procedure and lubricant type.
• Belts: Inspect the drive belts and PTO belts for wear, cracks, or fraying. Replace them as needed to prevent slippage or breakage.
• Tyres: Maintain correct tyre pressure for optimal stability and cutting performance.
• Cutting Deck: Keep the cutting deck clean of grass and debris. Sharpen and balance the mower blades regularly for a clean cut and to prevent vibration.
