Toro Power Max 724 OE (Model 37779 / 37798)
Modern 24-inch two-stage snowblower powered by a Toro Premium 212cc OHV engine with Quick Stick chute control and Anti-Clogging System (ACS).
Quick-Glance Shop Specs
Full Matrix ↓The Toro Power Max uses heavy-duty hardened auger gear-drive bolts instead of conventional break-away shear pins; never drill out or substitute softer Grade 2 shear pins, or the auger gearbox worm gear will strip under normal wet pack loads. Always coat the hex drive shaft under the belly pan with dry graphite lube rather than grease to prevent gumming the friction wheel sliding collar.
OEM Preventative Maintenance Schedule
Factory operator manual checkpoints for Toro Power Max 724 OE (Model 37779 / 37798)
Before Each Use / Daily
- Check engine oil dipstick level and wipe debris from air shroud intake
- Inspect auger blades and impeller housing for ice buildup or foreign objects
- Verify free movement and locking function of Quick Stick chute control cables
- Inspect skid shoes and scraper bar clearance above surface
First 5 Operating Hours
- Drain initial factory break-in engine oil while warm and refill with SAE 5W-30
- Check and adjust tension on auger/impeller and traction drive cables
- Inspect auger gearcase mounting fasteners and belly pan hardware torque
Every 25 Operating Hours / Seasonally
- Inspect rubber traction friction wheel for wear, cracking, or grease contamination
- Inspect drive and impeller V-belts for glazing, stretching, and fraying
- Lubricate drive wheel axle bushings and hex shaft with dry graphite spray
- Check tire pressure and adjust to 12-15 PSI evenly across drive axle
Every 50 Operating Hours / Yearly
- Change engine crankcase oil using 5W-30 synthetic small-engine oil
- Remove and inspect spark plug; clean electrodes and re-gap to 0.030 in
- Grease auger shaft zirks (if equipped) using NLGI No. 2 lithium complex grease
- Inspect scraper bar and reversible skid shoes; rotate or replace if worn to housing margin
Every 100 Hours / 2 Years
- Replace spark plug with new NGK BPR6ES or Torch F6RTC
- Inspect and replenish auger gearbox lubricant (Toro SAE 80W-90 or GL-5 EP gear oil)
- Replace auger/impeller drive V-belt and traction drive V-belt as a matched preventive set
- Inspect friction disc assembly bearing and drive pinion teeth
End of Season / Extended Storage
- Add fuel stabilizer and run engine dry, or completely drain fuel tank and carburetor bowl
- Remove spark plug, ground cylinder with a teaspoon of oil, and pull recoil to coat bore
- Touch up paint chips inside auger housing and chute to prevent rust pitting

Ignites air-fuel charge in 212cc OHV combustion chamber; fouled plug causes hard cold starting and misfires.
Transfers engine crankshaft power to the impeller and auger input shaft pulley.
Drives the intermediate traction pulley and friction drive plate from the engine crankshaft.
Filters sediment and varnish from fuel tank before reaching carburetor needle/seat.
Auger Belts, Shear Pins, Skid Shoes & Drive Components
Category-matched heavy wear & chassis replacement parts across OEM and wholesale counters
Rubber-ring disc that contacts the spinning drive plate to provide variable-speed ground drive propulsion.
High-carbon steel wear strip bolted to the lower lip of the auger housing to scrape pavement clean.
Reversible side runner skids that set housing clearance and protect the auger housing from abrasive surface wear.
Hardened Grade 5/8 specific bolt coupling auger shaft to drive; absorbs shock without premature snapping.

Common Issues (3)
Toro Power Max 724 OE (Model 37779 / 37798): Machine does not propel forward or reverse when traction bail is engaged
Root Cause: Friction wheel rubber tire worn down, delaminated, or contaminated with oil/grease leaking from hex shaft.
Shop Check: Drop belly pan, inspect friction ring (OEM 138-0679); clean aluminum drive plate with brake cleaner and install replacement friction wheel.
Toro Power Max 724 OE (Model 37779 / 37798): Impeller and auger stall immediately when hitting moderate snow under load
Root Cause: Auger drive V-belt stretched, out of adjustment, or worn down beyond tensioner arm travel limit.
Shop Check: Adjust auger cable trunnion nut to take up cable slack; if tensioner bracket bottoms out, replace auger V-belt (OEM 138-0683).
Toro Power Max 724 OE (Model 37779 / 37798): Engine surges, hunts violently, or only runs with choke partially closed
Root Cause: Stale ethanol fuel gummed the tiny low-speed idle pilot jet or main jet emulsion tube.
Shop Check: Drop carburetor float bowl, remove brass main jet and emulsion tube, clear passages with carb cleaner and fine wire, or replace carburetor.
