Toro Super Recycler 21564
The Toro Super Recycler 21564 is a premium 21-inch gas-powered walk-behind mower designed for medium-sized residential lawns up to about ½ acre. It uses Toro’s Personal Pace Auto-Drive System, which automatically matches your walking speed, making mowing smooth and less tiring. Its Super Recycler cutting deck and finely tuned airflow design create excellent mulching performance, finely chopping grass clippings to feed your lawn naturally, while also offering bagging and side discharge options for versatility. For the best results, mow regularly so grass doesn’t get too tall or wet, and adjust the cutting height usually between 1 and 4.25 inches to suit your grass type and season. Keeping the underside of the deck clean and the blade sharp ensures maximum efficiency and even cuts. The mower’s SmartStow feature lets you fold and store it vertically, saving space and allowing easy access for cleaning or maintenance. Common troubleshooting issues include sluggish self-propel drive (often fixed with a cable adjustment or wheel cleaning), engine sputtering from stale fuel or clogged filters, and poor mulching from dull blades or wet grass. Routine maintenance, checking oil, cleaning the air filter, sharpening or replacing the blade, and keeping the deck clear will greatly extend the mower’s life and keep it running smoothly. Overall, the Toro 21564 is best for homeowners who want a durable, easy-to-use mower that delivers a clean, professional-looking cut with minimal effort and maintenance.
Yard size & suitability
- The mower has a 21-inch (53 cm) cutting deck and is rated for yard sizes “up to ½ acre”.
- Some spec sheets indicate a range of ~¼ to ½ acre for optimal performance.
- So, if you have a typical suburban lawn (say 0.2-0.5 acres) this mower is a very good fit. If you have much larger than ½ acre you may find more efficient to use a wider deck or a riding mower.
In short: Great for medium residential lots; efficient, manageable size.
Best practice for using it efficiently
Here are tips to get the most out of the 21564 and keep your mowing experience smooth:
1. Deck & height of cut setup
- The height of cut adjusts from ~1.0″ to ~4.25″ (≈2.5-10.8 cm) depending on model/year.
- Choose a mowing height appropriate for your grass type & season; cutting too low stresses the lawn and slows you down.
- Keep deck clear of buildup: mulch and bagging work best when underside is free of clumped grass.
2. Use of mulching / bagging / side discharge
- This model features the “Super Recycler” deck design: dual-blade accelerator, under-deck wedges, designed to finely mulch clippings and return nutrients to the lawn.
- If you frequently mulch, mow when grass is dry, avoid mowing when it’s very long all at once (which slows things and may bog the mower).
- Bagging or side-discharge is useful if grass is very tall, wet, or you want a super-tidy look.
3. Self-Propel / Personal Pace system
- The 21564 uses the “Personal Pace Auto-Drive” rear-wheel drive system, so the mower moves at your walking pace (you don’t have to push manually).
- For best efficiency: walk at a consistent pace, let the mower drive you rather than fighting it. Adjust your pace so you’re comfortable and the deck is covering evenly.
4. Storage & setup
- The SmartStow® vertical storage feature means you can store the mower upright to save space.
- Before first use: check oil level, fuel (fresh gas), blades are sharp, deck is clean.
- Regular maintenance (see next section) keeps the machine running efficiently so you expend less effort each mow.
5. Mowing pattern & technique
- For efficiency: mow in slightly overlapping passes, avoid stopping mid-pass.
- For mulching, don’t overload the deck: if the grass is too long or thick, raising height and/or mowing in two passes may improve performance.
- Keep speed moderate; letting the blades do their job rather than rushing through.
Common troubleshooting & tips
Here are common issues users report (and how to address them) for the 21564:
Problem: Movement or self-drive doesn’t work properly
- If the Personal Pace drive seems too slow, too fast, or jerky: there are adjustment procedures (see video instructions).
- Inspect wheel gears, bearings, and wheel hub for wear.
Problem: Engine sputters or bogs in heavy grass
- Solution: Before mowing heavy growth, raise the deck to a higher setting initially, clear any debris under deck, ensure blades are sharp.
- Check fuel quality: stale gas leads to poor performance.
- Ensure air filter is clean.
Problem: Poor mulching / clipping leftover between passes
- Tip: sharpen or replace blade (mulching requires a sharp blade with “sail” to pull grass).
- Make sure underside of deck is clean and free of buildup.
- Don’t mow when grass is wet or overly long; mower has to work harder.
Problem: Parts missing / quality issues (less common but reported)
- Some users reported missing mulch plugs or side discharge chute on delivery.
- Tip: Inspect new machine immediately, register for warranty, and verify all accessories present.
Routine maintenance tips
- Change or top off engine oil per spec (manufacturer recommends SAE 30, etc.).
- Keep spark plug clean and air filter clean.
- Sharpen blade at least once per season or more if necessary.
- Clean deck underside after mowing.
- Before storage: drain fuel or add stabilizer, clean machine, store dry.
Summary
This mower is a very solid choice for up to ~½ acre yard, particularly if you want a high-quality self-propelled walk-behind with mulching capability. By following proper setup (right height, sharp blade, clean deck), using the Personal Pace drive properly, and staying on top of maintenance, you’ll get efficient mowing with less effort. Troubleshooting mostly revolves around self-drive adjustments, blade/sharpness issues, and keeping the deck free of buildup.
