How much does a 42 riding mower weigh?
A typical 42-inch riding mower weighs about 400 to 600 lb, depending on the brand, engine size, transmission, and whether it has a stamped or fabricated deck. Your Craftsman 24738908 is a 21-inch walk-behind mower, so its manual does not list a 42-inch rider weight. See the 24738908 owner's manual for your mower’s model details.
Typical weight ranges for 42-inch riding mowers
Most 42-inch lawn tractors fall into these ranges:
- Entry-level lawn tractors: ~400 to 500 lb
- Heavier-duty lawn tractors: ~500 to 650 lb
- Garden tractors (some use 42-inch decks): ~600 to 900 lb
| 42-inch rider type | Typical weight | What changes the weight most |
|---|---|---|
| Lawn tractor | 400 to 650 lb | Frame strength, transmission, engine size |
| Garden tractor | 600 to 900 lb | Cast-iron components, larger transaxle, heavier frame |
How to estimate your exact mower weight
If you do not have the spec sheet for the exact riding mower model, we use these quick checks:
- Look for the model number tag under the seat or on the frame rail
- Check the owner’s manual/specifications for that riding mower model
- Add attachments into your plan (bagger, weights, snow blade) because they can add 20 to 150+ lb
- If you are loading into a trailer, confirm the ramp rating and trailer payload
Why it matters
Weight affects traction, hillside stability, towing limits, and whether your ramps, lift, or trailer can handle the mower safely. It also impacts how much the mower can compact soft turf.

Is it okay to run premium gas in a lawn mower?
Yes. On the Craftsman 24738908 gas walk-behind mower, it’s fine to use premium (higher-octane) gasoline, but it won’t improve cutting power or make the engine run “stronger” if the mower is already running correctly on regular fuel. Use clean, fresh gas and refuel safely.
What we recommend for fuel on model 24738908
Use fresh, uncontaminated gasoline and fill the tank carefully so you don’t spill fuel on painted or plastic parts. Follow the fueling steps and safety warnings in the Craftsman 24738908 owner’s manual.
- Use fresh gasoline (avoid stale fuel from last season)
- Keep dirt and water out of the fuel can and tank
- Do not overfill; stop at the bottom of the fuel tank neck
- Tighten the fuel cap until it clicks
- Move the mower at least 10 feet away from the fuel source before starting
Premium vs regular gas: what changes and what doesn’t
Higher octane mainly helps prevent knock in engines designed for it. Most walk-behind mower engines are designed to run well on regular unleaded, so premium typically adds cost without a performance gain.
| Fuel type | What you might notice | Best use case |
|---|---|---|
| Regular unleaded | Normal starting and mowing | Everyday mowing with fresh fuel |
| Premium unleaded | Usually no difference | Acceptable if that’s what you have available |
Why it matters
Fuel quality affects starting, smooth running, and storage reliability far more than octane. Fresh gas and safe fueling habits help prevent hard-starting, rough running, and avoidable fuel-related issues.
Safety reminders when refueling
- Gasoline is flammable; refuel outdoors
- Let the engine cool at least 2 minutes before refueling
- Wipe up spills before starting
- Never run the engine indoors due to carbon monoxide risk

What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” label usually refers to the engine rating, not the mower’s model number. For this Sears PartsDirect page, the mower model number is 247.38908 (often printed as 247.38908 on the product label and on the cover of the manual). Use the 247.38908 owner's manual to confirm the exact identification points.
Where to find the model number on the mower
We recommend checking these common locations on Craftsman walk-behind mowers:
- The rear of the deck near the discharge opening
- The top of the deck near the engine mounting area
- The handle support area (lower handle brackets)
- The product ID label near the height adjusters
- The front or side of the deck under the cover area
“6.75” vs. mower model number (quick comparison)
| What you see | What it usually means | Example from this model |
|---|---|---|
| 6.75 | Engine power family/marketing rating | Not the mower model number |
| 247.38908 | Mower model number used for parts lookup | Craftsman mower model 247.38908 |
| 126T02-0795-B1 | Engine model number used for engine-specific parts | Listed in the manual for this mower |
Why it matters
Using the correct mower model number (like 247.38908) helps us match the right parts for your deck and controls, such as the blade adapter, control cable, wheels, and grass bag. Using only “6.75” often leads to the wrong parts because many Craftsman mowers share similar engine ratings.
Tip: if you are matching parts for this mower
If you are shopping for common wear items, match by mower model first, then confirm by part number:
- Blade: 942-0741A (21-in deck mulching blade)
- Blade adapter: 748-04096
- Control cable: 946-04661
- Grass bag: 964-04119
