String trimmers can easily break through skin.
Instead, look for a model with a minimal gap, or one with an easy-to-remove cutting head so that you can quickly pop the head off and get rid of weeds. If there’s a large gap, be warned that tall grass will probably get wrapped around the shaft in that spot. It’s a good option if you need a string trimmer and any or all of the additional tools, and you don’t want to buy each separately.īefore you buy any string trimmer, look at the cutting head, where it meets the shaft of the trimmer.
For most models, you can also get a hedge trimmer, a pole saw, an edger, and a brush cutter, and even a cultivator attachment. This is an engine designed to accept different attachments, and it’s typically sold with a string trimmer head. With gas and some cordless string trimmers, you’ll have the option of buying a stand-alone tool or a powered base, also known as a split shaft. Below, we delve into these and other factors you should consider when shopping for a string trimmer. For the first time, battery-powered string trimmers-also called cordless string trimmers-now outsell gas models. Take note that electrics are better for the earth, and they’ve improved exponentially in performance in recent years. A small number of models have cords, usually only a foot long, so you’ll want to use them with an extension cord at least 50 to 100 feet in length. String trimmers-which are also sometimes referred to by popular brand names like Weed Whackers or Weed Eaters-have either a curved or straight shaft, and typically run on either gasoline or lithium-ion battery. A string trimmer can also clear a path through light brush. It can tackle tall grass and weeds, too-growth that might bog down a typical lawn mower. It’s the ideal tool for keeping the edges of your garden or walkway neat and tidy, and for manicuring around fence poles and tree trunks. The JPL results were just 4 seconds out, meaning you can be very confident you’ll find the asteroid.A string trimmer gets into places that a lawn mower can’t. Two hours later, it will have moved to RA 11h 02m 34.6s Dec +01° 39′ 34″. The absolute closest pass will be during the day, but at 18:00 on the 13th (that’s about 5am on Saturday), it gives me co-ordinates of RA 12h 18m 50.0s Dec -13° 54′ 07″. I asked the two major sources where I should point my telescope to see Apophis’ close pass on 13 April 2029.
#CRAFTSMAN GAS HEDGE TRIMMER UPDATE#
Looking back to the disagreement over 2023 BU with Stellarium, I suspect it was caused by a delayed update or something. Orbital elements of minor planets and other objects are updated on a regular basis. These speeds are fast enough for an observer with a telescope to actually see. At its peak, the apparent motion is up to 900 arcsec/min. But on Friday the 13th of April 2029, Apophis will graze the Earth. Early in 2029, Apophis moves across the sky at about 0.5 arcsec/min, which is still pretty fast for an asteroid. For my example, (99942) Apophis, the Minor Planet Center data includes apparent motion, in arcseconds per minute.
The closer asteroids comets and minor planets come to the Earth, the faster their apparent motion will be. Horizons picked it up immediately though. When I was looking for C/2022 E3 (ZTF) I couldn’t ever find it on the Minor Planet Center website. That is the same with a lot of these services. For the examples I’ve tried, the data from these two sources seems pretty consistent.īecause you’re dealing with a computer at the other end, they can be very touchy about how they accept your input. Your target object will appear in front of these stars. Assuming the input data is accurate, these coordinates will be for the background stars. The output will give you a pile of RA and Dec co-ordinates for the times to point your telescope.
