Choosing Your 42-Inch Riding Lawn Mower: A Buyer’s Guide
A 42-inch riding lawn mower is a fantastic tool for medium to large yards. It saves time and energy compared to a push mower. Finding the right one involves looking closely at a few important things. This guide helps you pick the best machine for your lawn.
1. Key Features to Look For
When shopping, check these features first. They make mowing easier and last longer.
Engine Power and Type
- Engine Size (CC): A bigger number usually means more power. For a 42-inch deck, look for at least a 18 to 22 horsepower (HP) engine.
- Engine Brand: Trusted brands like Briggs & Stratton or Kohler often mean better reliability.
- Fuel Type: Most use gasoline. Electric models are quieter but might need more frequent charging.
Deck Design and Cutting Quality
- Deck Material: A strong deck prevents dents and rust. Look for heavy-gauge steel.
- Adjustable Cutting Heights: You need options! Seven height settings (usually from 1.5 to 4.5 inches) let you handle different grass types.
- Discharge Options: Can it bag clippings, mulch them (chop them fine), or side discharge them? Versatility is key.
Transmission System
- Automatic (CVT/Hydrostatic): This is the easiest to use. You just use a pedal or a simple lever to control speed. Most modern mowers use this.
- Manual (Gear Drive): This requires you to stop and shift gears to change speed. It is usually cheaper but harder to use around trees.
2. Important Materials and Construction
The materials used determine how long your mower lasts. Good construction resists the tough job of cutting grass.
The frame must be sturdy. Look for a **welded steel frame** over a bolted frame. Welded frames offer superior strength.
The seat should offer good support. Padded vinyl seats are standard. If you mow for long periods, a high-back seat is a must for comfort.
Tires matter too. Turf saver tires are designed to grip the grass without tearing up the lawn, which is important for delicate yards.
3. Factors That Improve or Reduce Quality
Quality is often seen in the details. Higher quality means less maintenance and better performance.
Factors That Improve Quality:
- **Cast Iron Spindles:** These hold the blades and spin them. Cast iron lasts much longer than plastic or aluminum.
- **Easy Maintenance Access:** A good design allows you to clean the deck easily. Oil changes should not require taking the whole machine apart.
- **Good Turning Radius:** A tighter turning radius (smaller measurement) means you spend less time making U-turns around obstacles.
Factors That Reduce Quality (Things to Avoid):
- Very light plastic components, especially on the hood or fenders.
- Engines that are too small for the 42-inch deck size; they will strain and break down faster.
- Flimsy looking steering components.
4. User Experience and Use Cases
How you use the mower affects which features you prioritize.
Small to Medium Yards (Under 1 Acre): Comfort and ease of use are most important. Hydrostatic transmission is highly recommended so you can focus on steering, not shifting.
Medium Yards with Obstacles (Trees, Flower Beds): Focus on a tight turning radius and excellent visibility. A clear view of the cutting path helps prevent accidental damage.
Hilly or Wet Terrain: You need more engine power (higher HP) and possibly wider tires for better traction. Be cautious on very steep slopes; always check the manufacturer’s recommended slope limits.
10 Frequently Asked Questions (FAQ) About 42-Inch Riding Mowers
Q: What size yard is a 42-inch mower best for?
A: A 42-inch deck is perfect for yards ranging from about half an acre up to two acres. It cuts efficiently without being too bulky for moderately sized properties.
Q: Is hydrostatic transmission really better than gear drive?
A: Yes, for most people. Hydrostatic (automatic) transmission lets you control speed smoothly using pedals. Gear drive requires you to stop and shift gears, which is slower and more tiring.
Q: How often should I change the oil?
A: Generally, you change the oil after the first 5 hours of use (break-in period) and then every 50 hours of use, or once per season. Always check your owner’s manual for the exact schedule.
Q: Can a 42-inch mower handle thick grass?
A: It can, but it depends on the engine. Look for at least 19 HP for reliably cutting thick or slightly overgrown grass without bogging down the engine.
Q: What does “deck leveling” mean?
A: Deck leveling means making sure the cutting blades are set perfectly parallel to the ground. A level deck ensures an even cut across your entire lawn.
Q: Are electric 42-inch mowers powerful enough?
A: Modern electric mowers are surprisingly powerful and quiet. They work great for flat, well-maintained yards. They might struggle more than gas models on very thick, wet grass or steep hills.
Q: What is the difference between a sleeve bearing and a spindle?
A: Spindles are the housing units that hold the blades. A cast iron spindle is higher quality and much more durable than a simple sleeve bearing setup, leading to better blade support.
Q: How important is the turning radius?
A: It is very important if your yard has many trees, garden borders, or landscaping features. A tighter turning radius reduces the number of passes you need to make.
Q: Do I need special tires?
A: If your lawn is flat and you never drive on hard surfaces when mowing, standard turf saver tires are fine. If you have slopes, you might need slightly more aggressive tread, but be careful not to damage the lawn.
Q: How do I store my riding mower in the winter?
A: You should always stabilize the fuel (add a stabilizer or run the tank dry). Clean the deck thoroughly. Store the battery on a trickle charger. Keep it covered in a dry place.
