Craftsman 247775890 chipper/shredder Parts

Yes, a wood chipper is worth buying when you regularly handle branches, leaves, and brush and want to reduce hauling while making mulch. For the Craftsman 247775890 chipper/shredder, it is most worthwhile when you use it often and operate within the feed limits in the 247775890 manual.

When buying makes sense (vs. renting)

Owning is the better choice when you:

• Do seasonal cleanups multiple times per year (pruning, leaf drop, storm debris)
• Generate enough brush that repeated rentals cost more than ownership
• Want mulch on demand for landscaping and soil building
• Have storage space and can perform routine maintenance
• Prefer not to schedule rentals or transport a rental unit

What the Craftsman 247775890 is designed to handle

This chipper/shredder is designed to chip and shred normal yard vegetation. The operating guidance in the manual calls out two feed methods:

Feed location	Best for	Max size
Hopper assembly	Leaves and small branches	Up to 1/2-inch diameter
Chipper chute	Bulky material and heavier branches	Up to 3-inch diameter

Costs and upkeep to factor in

A chipper is “worth it” when you plan for wear items and safe operation.

• Cutting parts wear with normal use; dull edges reduce performance and increase clogging
• Off-season storage steps (fuel system care, cleaning) prevent hard starting later
• Safe feeding matters; use the tamper tool when pushing material, not your hands
• Keep the work area clear and keep children and pets away during operation

Why it matters

Matching the machine to your debris volume and staying within the hopper and chute size limits prevents jams, reduces wear on blades and flails, and helps the chipper/shredder run safely and efficiently.

Yes. Your Craftsman chipper/shredder model 247775890 can shred leaves, but wet leaves mat together and commonly clog the hopper and discharge area, which slows output and can make the engine bog down. For best results, shred leaves that are only slightly damp (see the 247775890 owner's manual).

Best way to shred damp leaves

• Let leaves dry for a few hours (or overnight) before shredding.
• Mix damp leaves with dry leaves or small twigs to keep material moving.
• Feed small amounts at a steady pace; do not pack the hopper.
• Use the tamper to push material as needed; never use your hands.
• If the unit plugs, shut it down and clear the buildup only after everything stops.

What to do if wet leaves clog the machine

Wet leaves can plug the internal screen and discharge area. Use this quick checklist:

Symptom	Likely cause	What to do
Discharge slows a lot	Leaves are too wet and matting	Feed smaller batches; mix in dry material
Material becomes stringy	Cutting edges are dull	Sharpen or replace the cutting blades
Frequent plugging	Screen/discharge area packed	Shut down safely; clear buildup

Why it matters

Wet material increases load on the impeller and can block the flail screen area, which reduces shredding efficiency and leads to repeated stalling and messy clogs. Keeping material reasonably dry also improves bagging and overall performance.

On the Craftsman 247775890 chipper/shredder, “chipping” and “shredding” are two different functions: chipping handles thicker branches through the chipper chute, while shredding breaks down leaves and small twigs through the hopper. This model is designed to do both; see the 247775890 owner's manual.

How chipping vs. shredding works on model 247775890

• Shredding (hopper): leaves and small branches up to 1/2 inch diameter feed into the hopper.
• Chipping (chipper chute): bulky material and branches up to 3 inches diameter feed into the chipper chute.
• Feeding safety: if you need to push material, use the tamper, not your hands.
• Bagging: the smaller chip bag is for chips; the larger leaf bag is for shredded leaves.

Quick comparison

Function	Where you feed it	Best for	Typical output
Shredding	Hopper assembly	Leaves, twigs, small branches	Finer mulch-like material
Chipping	Chipper chute	Heavier branches	Coarser chips

Tips to get better results

• Feed material within the stated size limits to reduce clogs and kickback.
• Mix dry leaves with small twigs so the shredder grabs and processes material more consistently.
• If the unit starts clogging more often, shut it off, disconnect the spark plug wire, then clear packed debris from the hopper or chute.
• If the unit runs out of fuel while chipping or shredding, clear any clog before restarting.

Why it matters

Using the correct feed area for the material protects the cutting system, reduces jams, and helps you get the chip size or mulch texture you want while operating safely.
