An introduction to hydraulic excavators...

Coit Tower is a typical San Francisco landmark located on Telegraph Hill to the north side of the Financial District. Coit Tower could be seen from many places of the city, and is reachable via a steep road and from the usual walking path. Coit Tower stands 180 feet tall, and many visitors like to contact the top of the tower for eye-catching looks of San Francisco and the nearby areas. Coit Tower as well features a series of murals painted in the Works Progress Administration, portraying local occupations and neighborhoods.

Coit Tower was built with funds provided by Elizabeth Wythe
Lillie Hitchcock Coit, who donated a third of her fortune upon her death during 1929 to smarten the city of San Francisco. Lillie Coit was a world voyager, and brought back many relics from her experiences, but in fact regarded San Francisco as her true home and desired to stay a permanent legacy to the city. The funds were used to build two memorials: Coit Tower, and a sculpture in Washington Square that depicts three firemen.

It is generally believed that Coit Tower was built as a memorial to the firemen of San Francisco, as Lillie Coit was a lifelong enthusiast of the fire department. However, in spite of the tower’s similarity to a fire nozzle, many historians agree that Coit Tower was just built to improve the beauty of the city. Coit Tower is as well surrounded by steep sceneries grounds which are as well pretty pleasant to be walked through.

Visitors to Coit Tower could take a pulley to the top, appreciating the mind blowing murals along the way. The murals have been reinstated and as well particularly treated so that they would always remain integral, and are considered a very vital part of the history of San Francisco. Among other things, the murals portray farmers in the fields, a bank robbery, and a view into the port, a busy city street, and a lot of variety of other scenes as well. San Francisco Shuttle Tours are accessible of Coit Tower in which the murals are explained in detail. The walk is extremely physically demanding, and space for cars is also limited. Getting to Coit Tower is well values the attempt, however, as visitors are content with a peaceful setting and the striking views of a beautiful city.

Using Rain Barrels to Survive Droughts...

If you’re a gardener that has an unlimited supply of water, consider yourself lucky. There are many of us who live in drought zones where the garden and lawn watering rules are very constrictive to the healthy growth of gardens and plants. Many people just give up when they find out how few gallons of water they are permitted to use, but some of us  have just found ways to cope with less water. There are many ways to optimize ones garden to conserve water while still keeping it lush.

Some of the ways include drip irrigation (the use of a pipe or hose with small holes to gradually seep into the roots of the plant), the placement of plants in groups of equal watering needs (to prevent wasting water on plants that don’t need it), and using compost or mulch to insulate the water and prevent drainage.

But one of the best ways to keep your garden alive during a drought is to take preventative measures. Occasionally a drought will be predicted far in advanced, or those already experiencing a drought will be given a few weeks of heavy rain. When this occurs, you should take the opportunity to set up several rain barrels. Many people think this would be a time consuming, silly thing to do. But it can save you many gallons of water, and hardly requires any work.

Finding the barrels will probably be the hardest part. You can use your own garbage cans, or head to your home  improvement store to get a few 55 gallon plastic drums. These can be expensive and difficult to transport, so keep that in mind before you go to the store. You will probably want to cover the top of the barrel with a screen of some sort to  filter out any unwanted leaves or debris that might fall off the roof of your house.

Once you have your barrels ready, you’re faced with the decision of where to place them. Usually during rainfall, there is one corner or segment of the house that rain tends to pour off of. If you are taking the simple approach to barrel placement, just place the barrel under all the places where you see large amounts of drips. However, while this might be the easiest way to place them, you won’t see very high volumes of rain in the barrels.

If you want to take a more complicated approach to placing the barrels, you should consider tweaking your gutter system a bit. If you remove each individual segment and place it at a very slight slant so that all the water is diverted to the nearest corner of the house, you can place a rain barrel at each corner. So essentially your entire house acts as a catcher for the rain, instead of just a few feet worth of shingles. This is how to maximize the amount of water your rain barrel will catch.

After a heavy rainfall, each individual barrel probably won’t see very much rain. If it looks like it won’t be raining more  any time soon, it’s a good idea to empty each barrel into one main central barrel. Seal it and save it out of the way, for whenever you may need it. Then the next time it starts to rain, you’ll be able to quickly put all your catching barrels into place without having to lug around all the water you’ve accumulated so far.

The use of water barrels might sound like an antiquated idea. However, when you’re in the midst of a drought and  you’re able to spare that extra couple of gallons for your garden in addition the city allotment, you’ll be grateful for every bit of time and money you spent on collecting all that rain. All it takes is a few trips out in the backyard every time it starts to sprinkle, and you’ll be a very happy gardener when water isn’t so abundant.

Great Garden Tools...

Do you want to buy garden tools? Please read the following article first. Garden tool is one of the tools made for gardens and gardening and overlaps with various tools made for agriculture and horticulture. Garden tools can also be hand tools and power tools. Hand tools are still used by gardeners from the early agricultural implement used by humans: Shovels, that garden hoe, pitchfork, the garden fork, garden rake and the plow. The earliest tools were made of wood, flint and bone.

Development of metal working, first in copper and later in iron and steel, allows the creation of more durable tools. Industrial metalworking enabled the manufacture cutting tools, including pruning shears (secateurs) and cut the grass. The first power tool that has become popular with gardeners was the lawn mower.

Backpack Blowers...

Backpack blowers are more commonly used by professionals and are mostly powered by 2-stroke gasoline engines. The harness, which has a blower fit into it, is worn on the operator’s back. The engine and fan are also placed on the backpack frame with a hand-held hose and spout to direct the airflow. Backpack blowers are powerful, convenient and have larger, more efficient fuel tanks and air filters and therefore, longer duty cycles.

Backpack blowers with more than 40cc engines are the best with a typical blowing power of 400 cfm  (cubic feet per minute) of volume at 190 mph (meter per hour). If you live in a quiet neighborhood, these units are the best choice, because they are specially assembled to control unwanted noise. Also, keep in mind that harness quality and comfort differ from one model to the other.

Performance backpack blowers generally have blowing power of more than 450 cfm of volume at 195 mph, and are named because of their high performance. Though they may be noisier than other blowers, they are fast, fuel efficient, and have a quick throttle response. Most professionals and commercial users prefer this type of units, which also has optional accessories like breathable nylon back pads and padded, adjustable harnesses.

The largest and heaviest backpack blower units available are Big-bore Backpacks, with engine powers starting at 50cc. They are also fast and may decrease cleaning time in half. Since these blowers are very powerful, they are typically used for larger areas, and tough jobs like wet matted leaves. They are most suitable for commercial uses.

Robotic Lawn Mowers in the Future...

Robotic lawn mowers are going to be the next life-style changing appliance in America.  Think about it, how many times have you wanted to get away for the weekend or go to some event but yard work kept you tied to the house?  I can’t tell you how many golf outings I have missed.

Robotic lawn mowers can mow the yard, go back to the charger, and go back out again on their own without human intervention.  This is a large step forward from only two or three years ago.

Residential robotic lawn mowers run on batteries, so they don’t use gas or oil.  They are pretty much maintenance free except for the occasional replacement of the blades. They waterproof and they don’t rust.

A perimeter wire, like an invisible dog fence is placed around the yard to define the mowing area.  Gardens, flowerbeds and trees can also be easily protected.  Running the wire is not difficult, you can DIY or have it professionally installed.  The wire can be buried up to 2 inches deep.

The robotic mowers must sense the presence of the wire around them.  If the mower should somehow go past the boundary it will immediately shutdown, so you don’t have to worry about it running down the street (unlike your dog).

You can set the time for them to mow.  Since they are quiet and don’t need to see the yard, they can be allowed run at night while everyone is in the house or even asleep.

On schedule they will depart from the charger and start to mow.  When they run over the wire or into an object they will turn and go another direction.  Some mowers use a random pattern while others go back and forth.  When the battery gets low they find the perimeter wire and follow it back to the charger.  All robotic mowers on the market today do a very good job covering the yard and not leaving uncut patches.

Ensure that the robotic mower you are interested in goes back to the charger on its own the added expense will be worth it.  A rain sensor is a must-have as well, some robotic mowers are heavy and can get stuck in soft areas.

Robotic lawn mowers are now useful and practical.  They are still an oddity, so if you get one expect the neighbors to come from blocks around to watch it work.
