Craftsman has been a staple in American garages for decades, moving from Sears showrooms to Lowe's and Ace Hardware shelves. Whether you have a vintage "grey deck" or a modern T-series rider, understanding the specific quirks of Craftsman’s outsourced manufacturing is key to a long-lasting machine. This hub serves as my master reference for diagnosing the unique overlaps between Craftsman branding and the engines that actually power them.
Craftsman does not manufacture their own engines; they partner with giants like Briggs & Stratton, Kohler, and MTD to build their equipment. Historically, their "917" prefix indicated a Husqvarna-built machine, while "247" signaled MTD origins, leading to a wide variance in frame and deck designs. They are best known for residential lawn tractors and walk-behind mowers that balance affordability with decent part availability. Today, under Stanley Black & Decker, you will see a mix of Kohler-powered riders and budget-friendly MTD-sourced push mowers.
Reliability is okay, but the Briggs 140cc engine's plastic carburetor is prone to gumming up quickly if fuel is left sitting.
Uses a 17.5 HP Briggs engine that often suffers from compression release failure on the camshaft, making it hard to crank.
The front-wheel drive cable is a frequent failure point, often stretching or snapping at the plastic handle engagement point.
The steering linkage is impressive but requires frequent greasing to prevent the specialized Turn Tight gears from binding.
These compact units often struggle with drive belt slipping if the tensioner spring is not perfectly adjusted or if debris enters the pulleys.
The 208cc engine is solid, but the shear pins are intentionally soft and break frequently if you hit even minor ice chunks.
Craftsman utilizes a variety of engine platforms, primarily the Briggs & Stratton Intek and EXi series, Kohler Courage and 7000 Series, and the MTD-sourced Powermore engines. I have spent years working on the 310000 series Briggs singles found in their riders and the 11P902 series engines on their push mowers. Identifying whether you have a vertical shaft Briggs or a horizontal shaft Honda-clone, like those on their pressure washers, is your first step in finding the right parts.
On Craftsman riders, the model number is almost always under the seat on a silver sticker, usually starting with prefixes like 917 or 247. For walk-behind mowers, look at the rear of the deck near the bagger or between the rear wheels for an 11-digit alphanumeric code. Snow blowers typically have the sticker on the rear frame or the side of the engine shroud, which is critical because the engine model and the chassis model are separate numbers.
The T-series tractors frequently experience hard-starting issues caused by the valves drifting out of adjustment on the Briggs Intek engines, which is often mistaken for a bad starter motor. On the M-series push mowers, I often see the auto-choke thermal wax motors fail, leading to a flooded engine or one that will not restart when hot. Additionally, the deck spindles on the 42-inch decks are notorious for seizing if the grease zerks are ignored during the mowing season.
Modern Craftsman equipment heavily utilizes plastic Briggs & Stratton 591137 style carburetors which are effectively non-serviceable, meaning replacement is usually faster than cleaning. On older Kohler-powered units, the Nikki carburetors are common and respond well to ultrasonic cleaning if you catch the varnish early enough. I always recommend installing an inline fuel shut-off valve on Craftsman riders to prevent gravity-fed fuel from leaking into the crankcase during winter storage.
I frequently replace the 591459 ignition coils on Craftsman Briggs engines because they tend to fail once the engine reaches full operating temperature. On riding models, the safety interlock switches under the seat and behind the brake pedal are the primary cause of no-crank scenarios I see in my shop. If your Craftsman will not turn over, check the 20-amp fuse located near the battery terminal before you buy a new solenoid or starter.
Craftsman parts are among the easiest to source because of their massive footprint; you can find OEM parts through Sears PartsDirect or generic equivalents at any big-box store. I generally recommend OEM for belts and carburetors to ensure proper tension and jetting, but aftermarket spindles and air filters are usually fine for the budget-conscious DIYer. Brands like Stens and Oregon offer high-quality replacements that often exceed the factory specs for blades and cables.
I tell my customers to change the oil every 50 hours or once a season using a high-quality 10W-30 or SAE 30 oil. The air filter should be checked every 25 hours, especially on the EXi "Just Check & Add" engines where keeping the oil clean is the only way they survive without drain plugs. Do not forget to grease the front axle pivots and spindles every 25 hours to prevent the steering from becoming stiff and unresponsive over time.
Craftsman's warranty typically covers 2 years for residential use, but this is often handled through a network of independent local shops rather than a dedicated factory center. Performing your own basic maintenance like oil and filter changes will not void your warranty, but internal engine or transmission work usually requires a certified technician. Keep your receipts for all filters and oil, as lack of maintenance is the most common reason I see warranty claims denied.
Never bypass the Operator Presence Control bail handle on your push mower or the seat switch on your rider, as these are designed to kill the engine in less than 3 seconds. On the newer Craftsman Zero Turns, ensure the lap bars are fully in the outward neutral position before attempting to start, or the safety circuit will prevent the starter from engaging. Always clear your yard of debris before mowing, as Craftsman decks are relatively thin-gauge steel and can be easily dented by rocks.
Always disconnect the spark plug, remove the key, and work in a ventilated area away from fuel. If you smell gas or suspect a fuel leak, stop and address it before continuing.
This is usually caused by a low battery or a bad starter solenoid, but check your ground wire for corrosion before replacing parts.
Yes, 10W-30 is the standard recommendation for most Briggs and Kohler engines used on Craftsman equipment in temperate climates.
Many newer M-series mowers are designed to be tipped to drain oil through the fill tube, but if it has a plug, it is located underneath the deck.
Look for a silver or white sticker on the frame; it often starts with 247 or 917 and is about 11 digits long.
This usually happens if you tip the mower on the wrong side and oil leaks into the exhaust, or if the oil level is overfilled.
This is usually a faulty seat safety switch or the engine is bogging down due to a clogged deck or a partially clogged carburetor jet.
