Product Description

Amazon.com Product Description

Ideal for both post-mowing maintenance edging and trimming grass in hard-to-reach areas mowers cannot access, this electric two-in-one tool from Black & Decker helps keep your yard looking its best. Powered by a 35 Amp motor that revolves at a speed of 10,000 RPM, the ST4500 cuts a 12-inch path quickly and easily. For fast transitions from trimming to edging, the "Groom 'n' Edge" head spins 180 degrees, while a flip-down edge guide gets close to tight areas around sidewalks, driveways, or pavement paths. There's also a convenient cord retention system to guard against unintended unplugging of the tool while you're working, and a built-in assist handle to minimize wrist fatigue.

1.0 out of 5 stars wore out quickly, March 23, 2009

This review is from: Black & Decker ST4500 3.5 amp 12-Inch Electric Trimmer/Edger (Lawn & Patio)

I bought this for about $40 thinking I'd gotten a good deal on a weed eater (hadn't looked around too hard)... used this twice then the spool housing wore out quickly. Doesn't look like the replacement spool has the part that wore out which is extremely unfortunate because its construction seems to be a hideous oversight, as least in my opinion.

Here's why: The spindle mechanism which causes the spool to spin and thus cut weeds is a small metal die with very shallow metal grooves. The spool housing connects to this and has a small die opening with shallow plastic grooves. When brand new these fit together snugly and create a tight fit for the spool to spin. What happens though in application is if there is any moderately dense vegetation and the spool does not get completely free, it will slow down but the die will still spin inside the plastic housing whereby causing the spool container to strip out on the inside. Soon, the spool housing just fell off and will not reconnect to the die.. it just falls off as soon as you start it up. I was hoping I could buy a replacement for this but it seems as though the replacement spool just contains the wire/ wire holder. The part that stripped out was the part that connects to this which is not, ridiculously, part of the replacement part. Two uses and my weed whacker is now whacked.

A classic example of a disposable society which we desperately need to get away from.

1.0 out of 5 stars Bump feed failed immediately, September 13, 2008

By 

Lawn Guy (Seattle) - See all my reviews

This review is from: Black & Decker ST4500 3.5 amp 12-Inch Electric Trimmer/Edger (Lawn & Patio)

After I started using this (brand new) ST4500 trimmer, the bump feed failed immediately and then jammed time after time.

If you want a trimmer that forces you to stop, dis-assemble, re-thread, re-assemble every time the cutting string gets short (or jams) -- this is the unit for you.

For everyone else - a complete waste of money.

1.0 out of 5 stars Defective by Design, June 24, 2009

By 

Mr. MP7 (Denver CO) - See all my reviews

This review is from: Black & Decker ST4500 3.5 amp 12-Inch Electric Trimmer/Edger (Lawn & Patio)

I concur with the other critical reviews here. This product is defective by design.

The symptom is excessive line breakage which results in the end trapped inside the feed spool.

The problem is undue wear at the metal grommet through which the line feeds from the spool. After some use, the end of the cord wears down 1/2 to 1", but the fatal flaw is that simultaneously the cord at the feed grommet has worn through 1/2 the diameter of the cord, significantly weakening the cord strength and causing eventual breakage near the spool exit point. The cord then retreats into the spool housing, disabling the bump feed feature. As another reviewer stated, it then requires disassembly to fix.

A pox on anyone who sells this piece of junk. Ironic that it is such a bad product that one big box store (HD) doesn't even carry it.
