For a current 39924 that otherwise runs and throws snow normally, treat surface-clearing quality as a chassis-height and geometry problem before treating it as an auger, battery or chute problem. Toro’s current troubleshooting table gives only two causes for this symptom: the skids and/or scraper are not properly adjusted, or tire pressures are unequal. Check both tires, restore equal pressure within Toro’s 116–137 kPa (17–20 psi) maintenance range, then inspect skid/scraper setup on a level surface. Toro specifies the scraper 3 mm (1/8 inch) above and parallel to a level surface, with different skid treatment for rough pavement and gravel. Do not promise bare-pavement scraping by forcing the housing lower than the manual specifies.
First separate “surface clearing” from “snow discharge.” Toro’s current troubleshooting table treats them as different problems. A machine that runs but throws snow poorly has a six-branch discharge table involving swath size, wet snow, a plugged chute, belt condition and ECO mode. A machine that throws normally but leaves too much snow on the driveway has a much narrower table: skid/scraper adjustment or unequal tire pressure. That distinction prevents a visible strip of residual snow from turning into an unnecessary battery, belt or impeller diagnosis.
Resolve the generation before using dimensions or maintenance steps. Toro Canada lists model 39924 serial 418053488–999999999 separately and links Form 3476-324 Rev A. The Power Max e24 name spans several earlier serial ranges, so an older manual can look relevant while describing a different revision. For this page the hard gate is 39924 plus serial 418053488 or higher. Once that is confirmed, the current manual supplies both the troubleshooting causes and the owner-level skid/scraper procedure used below.
Record the residue pattern before adjusting anything. Note whether the machine leaves a fairly even layer across the full 24-inch path, a heavier strip on one side, intermittent ridges after impacts, or only extra snow on rough/gravel sections. This is not a substitute for the manual; it is a way to preserve evidence. A repeatable side-to-side difference makes Toro’s unequal-tire-pressure branch especially important to rule out, while a sudden change after bumping the front of the machine makes skid movement worth checking because Toro explicitly warns that bumping the front on pavement while unclogging can move the skids.
Check tire pressure before changing skid height. Toro’s maintenance schedule says to inflate the tires to 116 to 137 kPa (17 to 20 psi), and the troubleshooting table specifically identifies unequal pressure as a cause when the machine does not properly clear snow from the surface. The target is not simply “both tires feel firm.” Use an appropriate gauge on both sides and compare them. Keep both within the published range and equal to one another rather than raising one side or lowering the other to compensate for a scraper problem.
Then inspect the skids and scraper on a level surface with the machine fully shut down. Toro says this check is yearly and is intended to keep the auger from contacting paved or gravel surfaces while compensating for wear. The current procedure starts with tire pressure, then loosens both skid fasteners enough for the skids to move vertically. Toro’s key geometry is that the scraper should be 3 mm (1/8 inch) above and parallel to a level surface, and the auger blades must remain supported above the ground by the skids. Treat those as setup boundaries, not invitations to lower the machine until metal contacts pavement.
Surface type changes the correct result. Toro says that on cracked, rough or uneven pavement the skids should be adjusted to raise the scraper. On gravel, the skids are adjusted farther down so the machine is less likely to pick up rocks. Those settings intentionally increase clearance. A small amount of snow left on an irregular or gravel surface therefore cannot be judged against a “bare concrete” expectation. This is why a useful troubleshooting page must ask what surface is being cleared before declaring the scraper too high.
If the symptom appeared after clearing a clogged chute by bumping the machine, recheck the skids before touching anything else. The current operating section warns that bumping the front of the machine on the pavement may cause the skids to move, and it directs the owner back to the skid/scraper adjustment procedure and secure skid bolts. That gives you a strong before/after clue: a machine that cleared evenly earlier in the storm but began leaving a layer immediately after repeated front-end bumps may have changed skid position without any failure in the battery, motor, auger or impeller.
Wear belongs in the inspection, but do not jump straight to parts. Toro tells you to adjust skids and scraper as needed to compensate for wear and notes that excessively worn skids can be turned over to place the unused side toward the pavement. The manual does not say that every surface-clearing complaint requires a new scraper. First verify equal tire pressure, correct 3 mm scraper geometry, parallel alignment and securely tightened skids. If those conditions cannot be achieved because a component is bent, damaged or beyond usable adjustment, then replacement/service becomes evidence-based rather than speculative.
Use a controlled retest instead of judging the result in deep, irregular snow. After adjustment, choose a short, level paved strip with a consistent snow layer and make one normal pass. Look for a consistent path, no auger-to-ground contact, no strong pull or housing tilt, and no new metal scraping. Do not repeatedly lower the scraper to chase a thinner film. If the machine remains visibly uneven after both tires are equal and the current skid/scraper geometry is correct, stop changing the setup and document the exact pattern for Toro service.
Keep the safety boundary firm. Before adjusting, servicing or cleaning, Toro requires the machine shut off, electric-start key removed, all movement stopped and battery packs removed. If a chute clog is involved, never put your hands into the discharge chute. The cleanout-tool procedure and the skid adjustment are separate tasks. A troubleshooting guide should not convert a surface-clearing complaint into working around a powered auger or defeating the clearance designed to keep the auger off the ground.
Before checking or adjusting tire-related chassis height, skids or scraper, move the machine to a level surface, shut it off, remove the electric-start key, wait for all moving parts to stop and remove all battery packs. Keep the auger supported above the ground by the skids. Never put hands into the discharge chute, and do not lower the housing until the auger or scraper is forced into pavement in an attempt to achieve bare-surface clearing.
Diagnostic sequence
Confirm model 39924 and serial 418053488+
Why this check: Toro assigns the current 3476-324 Rev A manual to this distinct serial generation.
What to do: Read the model/serial decal and select 418053488–999999999 in the Toro Canada parts portal before using dimensions or adjustment steps.
What the result means: If the serial is earlier, stop and use the manual for that exact range.
Separate surface residue from poor throwing
Why this check: Toro gives different troubleshooting tables for poor discharge and for snow left on the surface.
What to do: Confirm the machine starts, drives, auger/impeller operates and snow is being thrown normally before using this surface-clearing sequence.
What the result means: If discharge is weak or absent, switch to the poor-discharge guide instead of changing skid height.
Measure both tire pressures
Why this check: Unequal tire pressure is one of only two causes in Toro’s current surface-clearing troubleshooting row.
What to do: Use a gauge on both tires; bring both to equal pressure within 116–137 kPa (17–20 psi).
What the result means: Retain equal pressure as the baseline before evaluating the scraper or skids.
Check scraper height and parallelism
Why this check: Toro specifies the scraper 3 mm (1/8 inch) above and parallel to a level surface.
What to do: With power removed, place the machine on a level surface and inspect both ends of the scraper while the skids support the auger housing.
What the result means: If height or parallelism is wrong, adjust the skids/scraper using the current manual rather than compensating with tire pressure.
Match the setup to the surface
Why this check: Rough pavement and gravel require more clearance than smooth level pavement.
What to do: Identify whether the problem occurs on smooth paved, cracked/rough or gravel surface and apply Toro’s corresponding skid guidance.
What the result means: Do not diagnose a normal safety clearance on rough/gravel terrain as a failed scraper.
Recheck skids after front-end bumping
Why this check: Toro warns that bumping the front on pavement while unclogging can move the skids.
What to do: If the symptom appeared after that maneuver, inspect skid position and bolt tightness before any parts replacement.
What the result means: A shifted skid is a setup correction, not evidence of battery or auger failure.
Inspect wear only after geometry is verified
Why this check: Toro allows adjustment for wear and notes worn skids may be reversed, so wear does not automatically equal replacement.
What to do: Look for wear, bend or damage only after tire pressure, scraper height and skid position are confirmed.
What the result means: Escalate to replacement/service only when correct geometry cannot be maintained or a part is visibly damaged.
Before you order parts
Do not buy a scraper, skid, auger part or belt until both tire pressures are measured and the current skid/scraper geometry is checked.
Do not compensate for a high scraper by intentionally running unequal tire pressures; Toro identifies unequal pressure itself as a fault branch.
Do not lower the housing to the point that the auger contacts pavement. Toro requires the auger blades to remain supported above the ground by the skids.
Do not assume a thin layer on gravel or rough pavement proves a defect; Toro intentionally raises clearance for those surfaces.
If the symptom began after bumping the front to clear a chute, recheck skid position and bolt tightness before replacing anything.
A worn-looking skid is not automatically scrap: the current manual says excessively worn skids can be turned over to use the unworn side.
Retest without creating a second problem
After adjustment, confirm both tires are equal and within 116–137 kPa (17–20 psi), both skid fasteners are secure, and the scraper is parallel at the specified clearance for the surface.
Reinstall batteries and key only after tools are removed and the machine is back in normal operating configuration. From the operator position, make one short pass on a level paved strip with consistent snow.
Observe whether the residual layer is now even and reduced without auger contact, harsh metal scraping or a housing tilt. Record left-versus-right behavior rather than immediately readjusting.
If surface clearing remains markedly uneven with equal tires and verified geometry, stop repeated lowering/raising cycles and provide model, full serial, surface type, measurements and residue pattern to Toro service.

Questions people get wrong
Why does my Toro 39924 leave a layer of snow even though it throws normally?
For serial 418053488+, Toro’s current troubleshooting table points first to skid/scraper adjustment or unequal tire pressure. Check those before diagnosing the battery, auger or belt. Do not buy a scraper, skid, auger part or belt until both tire pressures are measured and the current skid/scraper geometry is checked.
What tire pressure should I use on the current Power Max e24 39924?
Toro’s current maintenance schedule specifies 116–137 kPa (17–20 psi). For this symptom, the important point is also that the two tire pressures are equal. Toro Form 3476-324 Rev A covers Power Max e24 model 39924 serial 418053488 and up. Unequal tire pressure is one of only two causes in Toro’s current surface-clearing troubleshooting row.
Should the scraper touch the pavement?
The current manual specifies the scraper 3 mm (1/8 inch) above and parallel to a level surface, with the auger supported above the ground by the skids. Do not force the housing lower simply to chase bare pavement. With power removed, place the machine on a level surface and inspect both ends of the scraper while the skids support the auger housing.
Why did it start leaving snow after I bumped the front to clear a clog?
Toro specifically warns that bumping the front on pavement can move the skids. Recheck skid position and secure the bolts before assuming another component failed. If the symptom began after bumping the front to clear a chute, recheck skid position and bolt tightness before replacing anything.
Is some remaining snow normal on rough pavement or gravel?
The manual calls for extra clearance on cracked/rough surfaces and a lower skid position on gravel to reduce rock pickup risk. Those settings can intentionally leave more clearance than smooth pavement. Identify whether the problem occurs on smooth paved, cracked/rough or gravel surface and apply Toro’s corresponding skid guidance.
