Craftsman 917273011 46" 20-hp 6-speed electric start garden tractor Parts

For the Craftsman lawn tractor model 917273011, we use high-quality detergent 4-cycle engine oil rated API SF, SG, or SH; choose SAE 10W-30 for temperatures above 32°F and SAE 5W-30 for temperatures below 32°F (cold-weather starting). See the 917273011 owner's manual for the viscosity chart and fill procedure.

Recommended oil type and viscosity

Use oil that matches both the API rating and the temperature range where you mow.

• Use API SF/SG/SH detergent oil (4-cycle engine oil)
• SAE 10W-30: best for typical warm-weather mowing (above 32°F)
• SAE 5W-30: best for cold-weather operation (below 32°F)
• Check oil level on level ground before starting
• Do not overfill; fill to the FULL mark on the dipstick

Oil capacity for model 917273011

Your tractor’s engine oil capacity depends on whether it has an oil filter installed.

Configuration	Approximate oil capacity
With filter	4.2 pints
Without filter	3.7 pints

Quick tips for clean oil and longer engine life

These habits prevent hard starting, smoking, and premature engine wear.

• Change oil every 50 hours of operation or at least once per year
• Check oil level before each use and after every 8 hours of operation
• Drain oil when warm (it flows out faster)
• Keep dirt out of the crankcase when removing the fill cap/dipstick
• Tighten the oil fill cap/dipstick securely after checking

Why it matters

Using the correct viscosity helps the engine stay properly lubricated across temperature changes; that reduces wear on internal parts and helps the tractor start easier in cold weather.

Yes. The Craftsman riding mower model 917273011 uses an engine oil filter, and our maintenance guidance calls for replacing it every season (or every second oil change if you run the tractor more than 100 hours per year). See the 917273011 owner's manual for the exact service steps and oil-change schedule.

How to tell if your mower has an oil filter

Most riding mowers with a pressurized lubrication system use a spin-on oil filter mounted on the engine block.

• Look for a metal canister-style filter on the side of the engine
• Check for oil lines or a threaded filter base near the crankcase
• Confirm the maintenance interval in the manual
• If you see only an oil drain plug and no filter, it is typically a splash-lube engine (not the case for this model)

When to replace the oil filter (model 917273011)

Use this schedule as your baseline:

Usage pattern	Oil filter replacement interval
Normal seasonal mowing	Every season
Heavy use (over 100 hours/year)	Every second oil change

Why it matters

A clean oil filter helps protect internal engine parts by trapping debris. If the filter is overdue, oil flow can be restricted and engine wear increases, especially during hot mowing conditions.

Helpful tips for a clean oil change

• Change oil with the engine warm (not hot) so it drains fully
• Replace the filter at the same time you change oil when you are doing seasonal maintenance
• Wipe the filter mounting surface clean before installing the new filter
• Check oil level after running the engine briefly, then top off as needed

Yes, many Craftsman mowers and tractors use Briggs and Stratton engines, but Craftsman also used other engine makers on different models. For Craftsman riding tractor model 917273011, confirm the engine maker by checking the engine ID tag and the engine section of the 917273011 owner's manual.

How to tell which engine your 917273011 has

Use the tractor model tag to get the right chassis parts, but use the engine tag to get the right engine parts.

• Find the engine ID label on the blower housing, valve cover, or near the starter
• Write down the engine maker and the full engine model and spec numbers
• Match those numbers to the engine maintenance and parts information in the manual
• If the tractor was repowered, trust the engine tag (not the hood decal)
• Use the manual’s maintenance schedule to choose the correct oil, plug, and filters

Service specs you can use regardless of engine brand

These specs are listed for the Craftsman 917273011 tractor and help with basic maintenance.

Maintenance item	Specification
Fuel type	Unleaded regular
Fuel capacity	3.5 gallons
Spark plug	Champion RC12YC, 0.040 in gap
Oil type	SAE 10W-30 (above 32°F), SAE 5W-30 (below 32°F)

Why it matters

Briggs and Stratton, Kohler, and other engine brands use different air filters, carburetor parts, ignition components, and tune-up specs. Confirming the engine maker first prevents ordering the wrong parts and helps avoid hard starting, surging, and poor power.
