Eight things you need to know about mulch mowing.

Fertilizing your lawn just got easier. Just let your grass clippings do the job for you. Grass clipping mulch is the natural way to feed your lawn essential nutrients. Here are eight things you need to know:

1. Mulch mowing allows clippings to be cut finely enough so that they can’t be seen when redistributed into the lawn.

2. Make sure your blades are sharp. Sharp blades help ensure a precise, quality cut.

3. Mulching returns nitrogen-rich nutrients to your lawn. This feeds your lawn and can reduce the amount of fertilizer you need.

4. Follow the “one-third” rule when mulch mowing, taking no more off than the top third of the grass blade. Fast-growing conditions will warrant more frequent mowing.

5. Mulching works better when the grass is dry.

6. The MulchControl™ System from John Deere is the easy way to mulch while you mow.

7. If tall or wet grass conditions result in unsightly clumps, your MulchControl™ System should be used in side-discharge mode.

8. If conditions warrant using your MulchControl™ System in side-discharge mode, clippings are likely to be visible for a few days as they decay.

This exclusive technology is available with One-Touch Technology on the John Deere X350 Select Series Riding Lawn Tractor with a 42-in or 48-in Accel Deep™ Mower Deck and other Select Series mowers.

Excellent cut quality

Flat-top design enables clean flow of material throughout the deck and out of the discharge area. This prevents cut material from interfering with the cutting of incoming grass, allowing the blades to cut the material cleanly.

More productivity

Deep, flat-top deck with a large discharge opening allows cut clippings to exit the mower deck with limited re-cutting, so more power is available for cutting and processing incoming grass.

Minimal recutting improves the mower's capacity to maintain excellent mowing performance in difficult conditions and at higher speeds.

Clean operating

Smooth, flat-top deck stamping has few places for material to catch and collect on top of or underneath the deck, so the mower deck stays cleaner and is easier to clean when serviced.

Limited amount of recutting means less small pieces of grass clippings collect on the mower deck or the operator.

Superior durability

Designed-in strength and durability features ensure many hours of trouble-free operation.

  • 42A is stamped from 12-gauge, 0.105-in (2.7mm) steel
  • 48A and 54A are stamped from 10-gauge, 0.135-in (3.4mm) steel
  • Durability features include double-captured anti-scalp wheels for greater strength, reinforced outer edge of the deck protection for strength and long life, easy-to-access spindle grease fittings with flip-up shields, and dual-stage electrostatic primer and powder-paint coatings to provide extra protection from rust.

Operator-friendly versatility

With the optional MulchControl kit installed (along with the special mulching blades that are included), changing from side-discharge to mulching or vice versa is done with the simple flip of a lever or touch of a button.
