Wood Chipper vs Shredder vs Mulcher: What Is the Difference?

Choose a wood chipper or chipper shredder if:

• You prune trees and shrubs every year and have piles of branches.
• You clean up storm limbs and want chips instead of brush pickup.
• You want wood chips for paths, play areas or bed mulch.
• Your branches are under 3 in; bigger wood is firewood or an arborist job.

Choose a shredder or leaf mulcher if:

• Your yard waste is mostly leaves.
• You want to shrink leaf bags or make leaf mulch and compost.
• You have little storage space and want a light electric tool.
• You already rake or blow leaves into piles.

A leaf mulcher. The WORX WG430 uses a bladeless line system that WORX rates at 53 gallons of leaves per minute with an 11:1 reduction, about 11 bags down to one, and it sits on a stand above a bag or can. Blower vacuums mulch as they collect: the WORX WG512 Trivac and EGO LV5005 list 16:1 ratios, and the Toro 51609 uses a metal impeller. A chipper shredder's top hopper also takes leaves, but a gas machine is a noisy way to process dry leaves and wet leaves clog it.

Before buying anything for leaves, try mowing them. Many university extension programs recommend shredding a moderate layer of leaves into the lawn with a mulching mower, which returns organic matter to the soil. A mulcher earns its place when leaf fall is heavy or you want leaf mulch for beds. See the best leaf vacuums and mulchers.

Small electric chippers such as the WEN 41119 are inexpensive and quiet enough for suburban use, but a 1.75 in capacity and a preference for straight, trimmed sticks means they are slow on a real brush pile. The Patriot CSV-2515 is the serious electric option: a maintenance-free 1.5 HP motor making coin-sized chips from branches up to 2.5 in, at a much higher price. Gas chipper shredders with 3 in capacity, like the Champion 3 in, SuperHandy 3 in and Earthquake K33, are the practical choice for larger lots and storm cleanup, with the noise and engine care that come with them.

Many homeowners do not. If you generate one big brush pile a year, renting a tow-behind chipper, using municipal brush pickup or having a tree service chip what they cut is often cheaper, and tree services frequently have surplus chips to drop off. Owning makes sense when you prune every season, live rurally without pickup, or want chips on demand. Remember the 3 in limit on homeowner machines: anything thicker is firewood, not chipper feed.

Owners of small electric chippers commonly report that they work well on dry prunings but jam on leafy, forked or green branches and require patient feeding. Gas chipper shredder owners praise how quickly they reduce brush piles and complain about noise, weight when moving them around, blade dulling from dirty wood and clogging from wet leaves in the shredder hopper. Owners of leaf mulchers like the WORX WG430 generally praise volume reduction on dry leaves and note that wet leaves and sticks slow it down.
