Toro 21565 21-inch Super Recycler® with Personal Pace® SmartStow® Lawn Mower
The Toro 21565 21-inch Super Recycler® with Personal Pace® SmartStow® Lawn Mower is a premium walk-behind mower designed for homeowners with small to medium-sized yards of up to about half an acre, combining durability, efficiency, and ease of use in one powerful package. It features a 163cc Briggs & Stratton EXi engine that provides reliable, consistent power without the need for regular oil changes, just top it off as needed, making it a low-maintenance choice for busy users. The 21-inch cast-aluminum Super Recycler® deck offers superior airflow and mulching performance, finely cutting and recirculating grass clippings back into the turf to improve lawn health while reducing waste and cleanup time. The mower’s Personal Pace® Auto-Drive™ self-propel system automatically matches your walking speed, allowing for smooth, effortless operation even on inclines or uneven terrain, and the rear-wheel-drive setup enhances traction and control. To use the Toro 21565 most efficiently, set an appropriate cutting height; typically, between 2.5 and 3 inches for most grass types, to reduce strain on the mower and maintain a healthy lawn, mow regularly to prevent overgrown grass from bogging down the blade, and keep the blade sharp and the deck clean to ensure optimal cutting performance and airflow. For wet or tall grass, switching from mulch to bag mode helps avoid clogging, while dry conditions are ideal for mulching to naturally fertilize your yard. Troubleshooting common issues is generally straightforward: if the mower won’t start, check for fresh fuel, a clean air filter, and a properly functioning spark plug; if the mower bogs down or cuts unevenly, clean the underside of the deck and inspect the blade for dullness or damage; and if the self-propel feature feels weak or inconsistent, inspect the drive cable and rear wheels for debris or wear. Keeping the mower well-maintained; with routine oil checks, air filter cleaning, and blade sharpening will maximize its lifespan and efficiency. Additionally, the SmartStow® feature allows for vertical storage, saving up to 70% of floor space and making cleaning and maintenance easier. Overall, the Toro 21565 is an ideal mower for homeowners seeking a high-quality, reliable, and user-friendly machine that delivers professional-grade results with minimal effort, offering excellent mulching capability, smooth handling, and long-term dependability for consistent, efficient yard care.
Yard-size capabilities
- Deck width: 21 in (53 cm) … so moderately wide for a walk-behind mower.
- Engine: 163 cc Briggs & Stratton EXi with about 7.25 ft-lb gross torque.
- Cutting height range: 1.0″ to 4.0″ (2.5-10.2 cm) via 4-point height adjuster.
- Drive: Rear wheel drive with “Personal Pace® Auto-Drive” self-propel that matches your walking pace.
- Recommended yard size: Up to about ½ acre for typical residential use.
- Additional features: Cast-aluminum Super Recycler® deck (for premium mulching), high wheels (8″ front / 10″ rear) for better terrain handling.
In practice: If your yard is up to roughly half an acre; with a mix of open space and some trees/obstacles; this mower gives good coverage and power. The 21″ width means fewer passes than a narrower deck, and the self-propel system helps reduce effort. If your lot is significantly larger (near 1 acre) or has very tall/overgrown grass frequently, you may still use it, but you’ll likely spend more time or make more passes compared to a larger deck model.
How to use for best efficiency
To get the most out of the 21565 and maintain efficient, quality performance:
- Set a proper cutting height for your grass type and season. Avoid cutting too low in one pass; that stresses the mower and the turf. For many lawns a height around 2.5″-3″ is a good compromise.
- Keep the blade sharp and the deck clean. A premium deck design like Super Recycler relies on strong airflow under the deck, so any buildup of clippings or debris underneath reduces performance and increases load on engine.
- Use the self-propel system wisely. With the Personal Pace feature you simply walk at your normal pace and the mower drives itself — don’t push harder than needed; let it maintain its pace for smoother cut and less fatigue.
- Choose the right discharge mode. This model supports mulching (its specialty), bagging, and side discharge (optionally). If you’re maintaining the lawn regularly and conditions are good, mulching is efficient and returns nutrients to the lawn. For wet/tall grass or cleanup jobs, bagging may be more practical.
- Use fresh fuel and maintain the engine. A premium mower like this benefits when the engine runs smoothly: check the air filter, ensure spark plug is clean and properly gapped, use fresh gasoline, maintain oil as recommended. A well-tuned engine means better cut, less stalling, and longer life.
- Mow frequently-enough. If you let the grass grow too tall or thick between cuts, the mower will have to work harder, time per cut goes up, and finish quality may suffer. Regular mowing pays dividends in time and effort.
- Handle terrain appropriately. While the high-wheel design helps with uneven ground, on if you have many steep slopes, heavy brush, or very rough terrain you may need to go slower or adjust height, so you don’t overload the deck/motor.
- Storage & convenience features help your efficiency: this model has SmartStow® capability (handles fold/flip for vertical storage) making storage easier and reducing handling hassle.
Easy trouble-shooting tips
Here are some common issues with this mower and how to address them:
- Hard to start / engine won’t start
- Use fresh fuel. Old/stale gasoline can cause starting issues.
- Check the spark plug: if fouled or worn, replace with the correct part (491055S for this engine) per spec.
- Air filter may be clogged, restricts airflow and causes poor performance.
- Check the throttle / blade-brake clutch and safety levers are properly set.
- Mower bogs down or struggles cutting
- Blade may be dull or damaged, sharp blade is essential for efficient cutting.
- Deck underside may be clogged with build-up, reducing mulching efficiency and airflow. Clean under the deck.
- Grass may be too tall or thick for a single pass at the set height raise the deck height or mow more frequently.
- Uneven cut, missed strips or poor finish
- Check that the deck is level and that wheel heights are consistent.
- Inspect blade for balance or damage; unbalanced blades cause poor finish.
- Wheels may be dragging or bearings worn; inspect rear wheel drive components
- Drive/self-propel system issues
- If the self-propel isn’t engaging or is inconsistent, check the drive cable/ linkage for wear/slack.
- Some users report rear wheels “jam” when backing up if the lever remains engaged.
- Mulching or bagging issues (clippings blowing out, bag not filling properly)
- Ensure mulching plug and discharge settings are correct for your mode.
- On bagging mode, ensure bag is properly seated and the bag’s tunnel/chute is clear.
- Avoid mowing very tall/wet grass in mulch mode alone, this can overwhelm the deck and lead to clumps or bag issues.
- Excess vibration or unusual noise
- Remove and inspect blade for bending or damage.
- Check deck bolts, wheel bearings, high-wheel components for play.
- Rear wheel drive components may need lubrication or bearing replacement if noise persists.
