LST540 trimmer: It Rips!!!

My new LST540 40V trimmer met every expectation. My lot is 3/4 AC. with many large trees, a home, detached garage/shop. I trimmed 75% of my property on a single full charge. I haven't had a working trimmer for a couple of seasons, so the growth was somewhat excessive. The LST540 cut through it easily, and to be fair, it probably would have finished the job on one battery if the property had been regularly trimmed. Regardless, as a person who regularly uses cordless tools in the construction business, I recommend purchasing an extra battery so you always have another charged battery handy. Better yet, do what I did: buy the B&D chainsaw to go with the trimmer. Then you not only have two batteries, but another great tool to use on your property. With the high cost of an extra battery alone, it's like getting the extra tool for half price.

Pros: rips through heavy grass and weeds as effectively as a gas trimmer, without the hassles a gas trimmer. very convenient, lightweight, trouble-free product.

Cons: For big jobs, it's a good idea to buy an extra battery, as with any cordless battery tool. And of course, the batteries are expensive. That's no surprise tho.

VERY hard to remove string spool casing!

Con:
(A) I have to screw a C-clamp against the spool casing tabs to get them to depress enough for removal of the cap to change the string spool. Didn't have this problem with old B&D trimmer. Very annoying.
(B) When the string breaks, sometimes the feed/crop is too short to reach the grass along the sidewalk with the edge guide down.
(C) When the string wraps around the trimmer head it makes a horrendous noise and could potentially damage the head. Have to stop; remove the battery; remove the casing head (an ordeal per (A) above); unwind the string wrapped under the trimmer head; cut it with scissors; reattach casing cap; reattach battery. (sigh)

Pros: Battery charges fast and (obviously) lasts longer than my 24v.

Cons: (A) The string spool casing requires hydrolic-stength fingers to press in the tabs! (B) Metal edge guide is useless. (C) As string is fed by the spool, it sometimes wraps around the trimmer head.

MAX Lithium Trimmer/Edger LST540

So.....ACE hardware carries the batteries and string I guess. Still researching. The moral of my story is that I am spending too much time trying to order replacement parts. Ease of ordering lacks....

Pros: Machine works great. I bit heavier than what I expected but I can be a wimp. Love the variable speed to your touch. This works well in delicate areas.

Cons: Purchased mine at Sears. Of course they don't have replacement parts such as an additional battery (doesn't really last that long) or string cartridges.

40v LST540 trimmer/edger

I very much like and enjoy using (as we know lawn work can be a chore) the 40v LST540 trimmer/edger. It has so many great features to make lawn work of trimming/edging much faster, easier, neater & keeps the operator in control, better balanced, and safer. It also has great lasting batteries. I can say from experience that for many years and I won't say how many years l have owned a few trimmers. In our first owned home I was the first one in our neighborhood to own and use a lawn trimmer/edger which attracted many individuals watching in disbelief. And then lawn trimmers only sold with the pulg in cord and the power they had was very poor. They sure have improved over the years and this one is the best I have ever owned. I have also owed a gas trimmer and this one is hands down much better and safer with no gasoline to mess with the dangerous storing issues, smelly fumes and noise have gone away and the chance of flying debris is way down with well designed speed control. Great adjustable pole height and convert from trimmer to edger.

Pros: (pros) Has many great features to make lawn trimming & edging much faster, easier, neater & keeps the operator in control with better balance and safer to use. low noise. longer lasting batteries.

Cons: my only con is the auto line or string cutting blade is made from too soft of a material and dulls very quickly and it must be sharpened often or you are forced to carry a cutter tool in your pocket.
