Current Canadian generation covered by the newer manual family. Toro lists 418053488–999999999 separately and ties it to Form 3476-324 Rev A.
If a current 39924 runs but discharge is weak, do not start with a replacement battery or belt. Toro's current troubleshooting order begins with how much snow is being fed per swath and whether the snow is extremely heavy or wet, then checks a plugged discharge chute, the auger/impeller drive belt and finally ECO mode under heavy conditions. Preserve what the auger is doing and whether the chute is actually flowing before buying parts.
Start with the symptom exactly as Toro defines it: the machine runs, but it discharges snow poorly or not at all. That is different from a 39924 that will not run, one that repeatedly cuts out, or one that cannot reach full power. The distinction matters because the current manual gives this discharge complaint its own six-cause row. Before touching anything, confirm model 39924 and serial 418053488 or higher, then note whether the auger/impeller is rotating, whether snow enters the housing, whether anything exits the chute, and whether the problem appears only in a dense bank.
The first branch is feed rate. Toro lists trying to remove too much snow per swath and tells the operator to reduce the amount removed per swath. In practice, the useful observation is whether a narrower bite restores a steady stream of snow. That is a controlled comparison, not a workaround to ignore a mechanical fault: keep snow type and machine setup similar, reduce only the width or amount being fed, and watch whether discharge returns. If it does, the machine was being overloaded by the intake rate rather than proving a failed belt.
The second branch is extremely heavy or wet snow. Toro separately warns not to overload the machine with that condition. Wet snow can make a machine look weak because the housing and chute must move a much denser mass than dry powder. Record whether the complaint exists in ordinary snow or only in saturated plow berms. If normal discharge returns in a lighter, narrower pass, preserve that load relationship. If almost no snow exits even under modest conditions, continue down the manual's mechanical and blockage branches instead of blaming weather for every poor-throw symptom.
A plugged discharge chute is the third listed cause and it has a specific safety boundary. Toro says that when the auger/impeller is running but no snow comes from the chute, the chute may be clogged. Never put a hand into the chute. The operator procedure first allows a controlled bump method from the operating position; if that does not clear it, shut the machine off, wait for all moving parts to stop, remove the key and batteries, and use the supplied snow-cleanout tool. After any bump-to-clear attempt, Toro also tells the owner to check the skids because the impact can move them.
Once the chute is physically clear, watch the auger/impeller response. Toro next lists an auger/impeller drive belt that is loose or off the pulley, followed by a belt that is worn or broken. Those branches belong after snow-load and blockage checks because a clear chute with the machine running but little or no driven snow movement is different from a chute packed solid with wet snow. Do not reach behind guards or inspect a moving belt. Remove all batteries and the key before inspection, and use Toro service information or an Authorized Service Dealer for belt installation, adjustment or replacement when the manual directs it.
ECO mode is the sixth cause in the current 3476-324 troubleshooting row. Toro specifically says to verify that ECO mode is not engaged in heavy conditions. ECO reduces rotor speed to save battery power and is intended for lighter clearing situations. Therefore, if discharge is acceptable in ordinary snow but falls off in a heavy section while ECO is active, turn ECO off and repeat a narrow controlled pass before assuming the battery, motor or belt is defective. Keep this test separate from a machine that truly loses electrical power or shuts down under load, which belongs to the no-run/protection branch.
The order of observations prevents one nearby symptom from being mistaken for another. A low battery state can contribute to a different 'does not reach full power' complaint, but the poor-discharge row itself is built around feed rate, snow condition, chute blockage, belt drive and ECO mode. If the motor stays running and the machine sounds stable while snow output fades, work this discharge sequence first. If the machine also beeps, cuts out, or cannot maintain power with the auger disengaged, document that separately and use the matching current-generation electrical guide rather than forcing all symptoms into one URL.
Stop at the service boundary when the chute is clear, ECO is off, the load is modest, and the auger/impeller drive still does not transmit normal motion or a belt fault is evident. The current manual's troubleshooting and drive-belt maintenance sections direct belt service to Toro information or an Authorized Service Dealer. Before service, record the full serial, snow condition, whether the chute was clear, whether the auger/impeller visibly engaged, whether ECO changed the result, and whether the symptom started suddenly after a jam or gradually over time. Those observations are more useful than a bag of parts purchased from the phrase 'won't throw snow.'
Keep hands and feet away from the auger, impeller and discharge opening. If the chute is clogged, never clear it by hand. Shut off the machine, remove the electric-start key, remove all battery packs and wait for all movement to stop before cleaning, inspecting or servicing. Use the snow-cleanout tool and follow Toro instructions for belt work; do not defeat guards or run the machine with covers removed.
Diagnostic sequence
Confirm 39924 and serial 418053488+
Why this check: Toro publishes Form 3476-324 specifically for this current serial generation.
What to do: Read the model/serial decal and select the 418053488+ range in Toro Canada before applying this sequence.
What the result means: If the serial is earlier, stop and use the manual linked to that earlier generation.
Reduce the snow feed before diagnosing parts
Why this check: Too much snow per swath is Toro’s first poor-discharge cause.
What to do: Make a narrower controlled pass at a pace that lets the machine process the snow instead of forcing a full-width bite into a dense pile.
What the result means: If a steady stream returns, preserve the load relationship and do not treat the improvement as proof of a bad belt.
Separate heavy/wet snow from an all-conditions fault
Why this check: Toro lists extremely heavy or wet snow as its own overload branch.
What to do: Compare behavior in a smaller amount of the same snow or in a less saturated section when safely available.
What the result means: Poor throw only in extreme wet load points first to operating load; poor throw in modest snow keeps the blockage/drive branches active.
Clear a plugged chute safely
Why this check: A running auger/impeller with no snow exiting can mean the chute is clogged.
What to do: Use Toro’s operator-position clearing method first. If it remains clogged, shut down, remove key and batteries, wait for all motion to stop, and use the cleanout tool—never your hand.
What the result means: Retest only after the chute and housing path are visibly clear and the skids remain secure.
Check the auger/impeller drive branch
Why this check: Toro next lists a loose/off-pulley belt and a worn/broken belt.
What to do: With all power removed, inspect only what the operator/service information allows. Do not reach into a moving drive or remove guards for a powered test.
What the result means: A clear chute plus abnormal auger/impeller drive behavior moves the case toward belt/service work.
Turn ECO off in heavy conditions
Why this check: The current troubleshooting table explicitly lists ECO mode under heavy conditions as a poor-discharge cause.
What to do: Disable ECO and repeat a short narrow pass under a comparable load.
What the result means: If discharge improves with ECO off, do not replace battery or belt solely from the original heavy-load test.
Before you order parts
Do not buy a belt before proving the chute is clear and reducing the amount of snow per swath. Toro places those owner-level branches before belt faults in the current troubleshooting table.
Do not buy a battery from a pure poor-throw symptom while the machine continues to run normally. Battery/no-run and full-power complaints have separate current-generation branches.
Do not replace parts because heavy wet snow throws a shorter distance than dry snow. Repeat a lighter controlled pass and preserve whether load changes the result.
Do not use ECO performance in a heavy bank as the baseline for full-power discharge. Toro specifically tells the operator to verify ECO is not engaged in heavy conditions.
Do not put a hand in the chute or reach into the auger/impeller drive. A jam and a suspected belt fault both require the machine to be shut down, keyed off and de-energized before inspection.
Retest without creating a second problem
After clearing any blockage, confirm the chute path is open, reinstall all guards/covers that were legitimately removed, insert known-charged batteries and start from the operator position. Verify normal auger/impeller engagement before feeding snow.
With ECO off, make a narrow pass in a repeatable section of snow. Keep the machine at a pace it can process and watch for a continuous discharge stream rather than judging only maximum throw distance.
If discharge is still poor, stop and remove the key and batteries. Record whether the auger/impeller was rotating normally, whether the chute stayed clear and whether belt movement or noise was abnormal. Do not continue repeated powered tests around a suspected drive fault.
If the machine throws normally in a narrow/light pass but fails only when the swath becomes very heavy or wet, treat that load dependency as the primary observation and avoid forcing repeated overloads.
Market/model notes
- Toro Form 3476-324 Rev A covers Power Max e24 model 39924 serial 418053488 and up.
- The current troubleshooting table lists six poor-discharge causes: too much snow per swath, extremely heavy/wet snow, plugged chute, loose/off-pulley auger/impeller belt, worn/broken auger belt, and ECO mode in heavy conditions.
- The manual separately warns never to use hands to clear a clogged discharge chute and provides a snow-cleanout-tool procedure.
- Toro’s Canadian product page describes the model as a two-stage 60 V machine with Quick Stick chute control and an Anti-Clogging System; those features do not remove the need to follow the current troubleshooting sequence when discharge is poor.
Questions people get wrong
Why does my Toro 39924 run but barely throw snow?
For serial 418053488+, Toro first lists too much snow per swath, extremely heavy/wet snow and a plugged chute, then auger/impeller belt faults and ECO mode in heavy conditions. Work those branches in that order rather than jumping straight to a battery or belt.
Can ECO mode reduce throw in heavy snow?
Yes. The current 3476-324 troubleshooting table explicitly says to verify ECO mode is not engaged in heavy conditions when discharge is poor. Poor throw only in extreme wet load points first to operating load; poor throw in modest snow keeps the blockage/drive branches active.
What if the auger is spinning but nothing comes out of the chute?
Toro says the discharge chute may be clogged. Never clear it by hand; follow the manual’s clearing procedure and use the cleanout tool after shutting down and removing power if the initial method does not clear it. If it remains clogged, shut down, remove key and batteries, wait for all motion to stop, and use the cleanout tool—never your hand.
When is a belt problem more likely?
After the snow feed is reasonable, the chute is clear and ECO is off, yet the auger/impeller drive still does not move snow normally. Toro then lists a loose/off-pulley belt or a worn/broken belt and directs belt service to Toro information or an Authorized Service Dealer.
