EGO snow blower accessories and winter maintenance

Check fit by model before ordering. This guide also covers the SNT2420 after-storm routine, its battery recommendation, and seasonal storage.

Before the first storm, I’d check the model number on the blower and keep its listed shear pins where I can find them. The part numbers are close enough to confuse: the SNT2420 operator's manual lists ASP2400 and ASP2420D, while EGO’s ASP2400D page names other models. The chute-cleaning tool comes attached to the SNT2420.

Check the part number against your blower

Part	What it does	Fit listed in the source
ASP2400	One shear pin and lock nut. EGO product details.	The SNT2420 manual lists ASP2400. EGO’s product page lists SNT2400, SNT2405, SNT2406, SNT2416, SNT2800, SNT2806, and SNT2807, but omits SNT2420.
ASP2420D	Shear pin set.	The SNT2420 manual lists this part for SNT2420. It does not confirm fit for other models.
ASP2400D	Two shear pins and lock nuts. EGO product details. Check ASP2400D 2-pack.	EGO lists SNT2400, SNT2405, SNT2406, SNT2416, SNT2800, SNT2806, and SNT2807. Its listed models do not include SNT2420.
ASS2420	The SNT2420 manual says the scraper bar picks up the lowest layer of snow so it can be thrown.	The SNT2420 manual lists ASS2420 for SNT2420. EGO’s scraper-bar page covers ASS2400, not ASS2420.
ASS2400	Replacement scraper bar. EGO product details.	EGO lists SNT2400, SNT2405, and SNT2406 only. That page does not list SNT2420.
AKS2420D	Pair of adjustable skid shoes. They set clearing height for uneven ground and help lift the auger housing over bumps. EGO product details.	EGO lists SNT2420 only.
ADC2400	Pair of drift cutters that direct drifts and packed snow into the auger housing. EGO product details.	The SNT2420 manual lists ADC2400. EGO describes it for a 24-inch self-propelled two-stage blower with Peak Power but does not give a model list.
ACT2400	Clean snow and ice from the discharge chute and auger housing. EGO product details.	EGO says it fits all EGO single-stage and two-stage snow blowers. The SNT2420 manual shows the tool attached to that machine.
CB004	Vented, weather-resistant cover for dust, dirt, and debris, with a zipper and elastic band. EGO product details. Check CB004 cover.	EGO lists SNT2400, SNT2405, SNT2406, SNT2406-4, SNT2410, SNT2416, SNT2800, and SNT2807. The SNT2420 manual also lists CB004. The Amazon title does not name SNT2420.
CB003	Two-stage cover to protect from dust, dirt, and debris. EGO product details.	EGO lists SNT2400, SNT2405, SNT2406, SNT2410, and SNT2416. It does not list SNT2420.
CB002	21-inch single-stage cover. Check CB002 cover.	The Amazon title names SNT2100, SNT2102, SNT2103, SNT2110, and SNT2114. EGO does not confirm this fit on a product page.

For the SNT2420, follow its manual’s part numbers: ASP2400 or ASP2420D, ASS2420, AKS2420D, ADC2400, and CB004. Similar names do not make the parts interchangeable. The manual’s parts diagram also shows the chute-cleaning tool on the machine.

After a storm

When you finish, the SNT2420 manual says to let the auger run for a few minutes to help keep moving parts from freezing. Move the blower in self-propel mode until the wheels rotate freely, then turn the chute left and right and move the deflector up and down. Clear snow and ice from the base of the chute.

If the chute clogs, shut the blower off, remove the battery packs, wait 10 seconds for the auger to stop, and use the attached clean-out tool. Never use your hand. Remove the battery packs before cleaning or doing maintenance.

The manual also calls for periodic checks of the whole machine for loose, missing, or damaged parts. It does not set a storm-count or hour-based interval.

Before storing it for spring

Remove the battery packs and store them somewhere secure and out of reach of children. Wipe moisture, dirt, or debris from around the battery compartment, then wipe the blower with a clean, dry cloth. Check the nuts, bolts, knobs, and screws for tightness and inspect moving parts for damage, breakage, and wear. Have damaged or missing parts repaired or replaced.

Store the blower in a clean, dry, enclosed place out of reach of children. The manual says not to store it near corrosive materials such as fertilizer or rock salt.

Plan on two packs for the SNT2420

The SNT2420 manual recommends two 5.0Ah-or-greater battery packs for best performance and maximum runtime. EGO’s 24-inch two-stage page ties its claim of up to an 18-car driveway in 8 inches of snow to two included 7.5Ah packs. That driveway figure applies to that stated setup.

The 7.5Ah Check BA4200T 7.5Ah battery matches the capacity in EGO’s driveway claim. The 5.0Ah Check BA2800T 5.0Ah battery meets the manual’s recommended lower capacity, but EGO does not publish that same driveway figure for two 5.0Ah packs. Check SNT2420 tool only.

Which accessories does the SNT2420 manual list?

The manual lists ASP2400 and ASP2420D shear pins, ASS2420 scraper bar, AKS2420D skid shoes, ADC2400 drift cutters, and CB004 cover. It also shows the chute-cleaning tool attached to the machine.

The EGO ASP2400D page lists SNT2400, SNT2405, SNT2406, SNT2416, SNT2800, SNT2806, and SNT2807. The SNT2420 manual lists ASP2400 and ASP2420D instead, so it does not confirm ASP2400D for SNT2420.

How many batteries does EGO recommend for the SNT2420?

The SNT2420 manual recommends two 5.0Ah-or-greater battery packs for best performance and maximum runtime. EGO's SNT2425 page ties its up-to-18-car driveway claim in 8 inches of snow to two included 7.5Ah batteries.

What should I do before storing the SNT2420?

Remove the batteries, wipe moisture and debris from around the battery compartment, clean the blower with a dry cloth, check fasteners, inspect moving parts for damage and wear, and store it in a clean, dry, enclosed place away from children, fertilizer, and rock salt.
