1.1 The evolution of the lawn mower
In the beginning, there was grass, and the sheep ate the grass. The grass was short, and it was good.
But not very efficient. So, until the 1830s, the few land-owners who had turf lawns and wanted to keep them trimmed used scythes or shears to chop turf to acceptable heights.
Then, Englishman Edwin Budding observed a cutter used in cloth factories for removing the nap from fabric. What if he took the same concept and built a machine that would cutgrass?
In the 170 years since Budding created his grass-cutting contraption, the lawn mower has evolved from a heavy, hard-to-maneuver machine into a diverse family of equipment with assorted features and differing levels of speed and cutting precision.
The invention also transformed the look of residences, parks and fields around the world. Manicured lawns were no longer limited to the estates of aristocrats with the simple and affordable cutting machines, most middle-class homeowners could maintain healthy and attractive lawns to enhance their properties.
Budding's brainstorm:
Around 1830, gardeners typically used scythes to trim turf. For the best results, the job had to be done when the ground was wet with dew-early in the morning or late at night. A less-than-careful effort might leave tell-tale, unattractive marks from the scythe.
When Buddings idea became a reality, it freed the workers to cut tur fat more convenient hours. Budding and his partner received a patent in1830 for his lawn mower.
“Country gentlemen may find in using my machine themselves an amusing, useful and healthy exercise,”
Budding said in his patent documents.
The machine was crude by modern standards. It consisted of a rear roller and a cutting cylinder in front. Gears sent power from the rear roller to the cutting cylinder. It was difficult to use-in many cases, two persons were needed: one to push, one to pull.
In time, others expanded on Budding's inspiration. There were machines that could be pulled by horses or other beasts of burden; models using chains instead of gears to drive the cutting unit, and side wheel mowers, in which the wheels them-selves drove the cutting cylinder.
By the 1870s, lawn mowers had be-come so simple to use and reasonably priced that they were becoming more common in American landscapes.
Power:
Lawn mowers were only as effective. as the strength and stamina of the person or animal pulling or pushing the machine. That began to change in the 1890s, as inventors and manufacturers looked at ways to bring engine power to lawn mowing.
A steam-powered mower was introduced in the 1890s, but it was heavy noisy and hard to control and maneuver. Just after the turn of the century, gasoline-powered machines became available and unlocked the door to productivity.
Powerful engines could push or pull more blades and provide a better cut. Gang mowers several cutting units pulled by a tractor-became common for cutting turf in parks and on golf courses. As cutting widths and productivity expanded, riding mowers became commonplace. Cutting units could be found at the front of a rear-engine mower, or at the rear of a tractor-driven unit.
Engine power also made rotary blades more feasible on mowers. Engines could provide the power to spin the rotary blade fast enough to cut the turf effectively. Rotaries became more popular after World War II, as engines became cheaper and more powerful, and the accelerating migration to the suburbs meant more people had larger lawns to maintain. Rotary machines were cheaper to make and maintain.
Other innovations:
Manufacturers have continued to strive to make mowers that are easier to use, more comfortable and provide a better cut.
Machines are available with hydraulics that put more power and precision in a landscaper s hands. Mowers can mulch grass clippings and spare workers the chore of raking and cleaning after the lawn is cut. Units with pneumatic tires have a light foot-print and allow mowers to traverse delicate ground such as golf greens.
By using levers instead of a wheel to steer a mower,zero-turn mowers al-low you to maneuver around obstacles and cut turf in areas that more conventional machines can’t reach.
Manufacturers are continually studying technological developments to see how they can build a better mower.
The future:
If you’re wondering what you might see in the lawn mowers of the future, keep your eyes on the road. Many of the improvements in lawn equipment stem from the auto-motive industry. We have to wait for the automotive industry to come up with the innovations and improvements, says Peter Whurr, vice president of product management for Textron Turf Care and Specialty Products. We do not have the huge volume they do. Lawn mowers are built in the hundreds as opposed to the thousands.
And, as automobiles have incorporated more computer technology into their systems, so will lawn mowers.
Computing is becoming incredibly fast and cheap, says Dana lonn, di-rector of the Toro Co.’s Center for Advanced Turf Technology. Break throughs in satellite technology. Such as global positioning systems (GPS)and remote imaging, will alow you to sense exactly where turf needs to be mowed.
That will not only improve the efficiency of your work force, but also lessen the effect on the environment
You will use technology to help you do only what you need to do only where it needs to be done, says Lonn.
Satellite systems will also be able to enhance equipment maintenance and anticipate breakdowns.
There is more and more talk about zero down time,"' says Bob Tracinski business communications manager for John Deeres Worldwide Commercial& Consumer Equipment Division. The trend is toward design durability in equipment that gets so much use.
He says a ‘black box ' equipped with a computer chip can be installed in a mower to monitors parts susceptible to wear and breakdown. When a part begins to show signs of fatigue or damage, the chip can transmit the in-formation to a GPS satellite, which can notify a dealer.
The dealer can get a new part out to the job site before the operator even knew there was a problem," says Tracinski.
The same technology will deter theft because the satellite will be able to detect where every piece of equipment is. It will allow landscape companies to map the most efficient ways to go from job to job, which will reduce crews' down times.
The technology is doable. Says Tracinski. It’s just a matter of getting the cost down.
Quiet and comfort:
Lawn mowers of the future will be environmentally friendlier, more comfortable, easier to use and have safety features better integrated into the design. Manufacturers will place greater emphasis on ergonomic design.
With the labor shortage in the land-scaping industry. people need to work longer hours, and they want riding equipment that is more comfortable to operate, says Tracinski. That means features like higher-back seats and lower noise levels, controls properly placed, things color-coded, easy on-and-off switches.
Companies are continuing to pursue alternative fuel sources for mowers to reduce air and noise pollution. Concerned about the effect that emissions from lawn mowers and other lawn and garden equipping are affecting the atmosphere, the U.S. Environ-mental Protection Agency is toughening emission standards for small engines such as those used on lawnmowers.
“You'll see significant changes in this area,” says Lonn. Mowers will have fuel cells instead of gasoline or diesel engines.
Batteries and fuel cells will progress. On the point that they will be able to provide enough power to trim turf without rousing the neighborhood from its sleep.
The noise would be so low that you wouldn’t even know a landscaper was out there working, says Whurr.
For example, Metallic Power(Carlsbad, Calif.) has agreements with Briggs Stratton, Toro and Textron for development of vehicles that use its zinc/air fuel cells. Units powered by fuel cells may be available in the next several years. They will be quiet and emission-free and should have enough power to fit well into regular maintenance operations.
Tracinski says that the industry is working to make that do not get in the way of a landscapers job safety features an integral part of the lawnmower.
There is a tendency for some commercial operators to bypass safety is-sues to increase productivity, says Tracinski. Companies try to build in safety in such a way that it is not seen as an obstacle to productivity.
In the same vein, manufacturers are striving to make lawn mowers simple to operate even for someone with no experience or mechanical back-ground. The labor shortage means it's notal ways possible to have someone with a knowledge of mechanics, or even speak English, says Tracinski. We are working to make the controls easy to operate and learn, so that a worker is ready to mow immediately.
A robotic herd:
Computers will also create smarter machines such as robotically con-trolled mowers.
They 're out there in their infancy says Whurr. You could be up on the porch putting your feet up while the mower does the job itself Manufacturers need to resolve several safety issues before machines can be sent out on their own. But they are close.
Were not that far away from having completely autonomous ma-chines, says Lonn. A machine will know where it is, will know how to avoid collisions. You can plan ahead what it is supposed to do.
Instead of five workers each riding a mower on a job, one worker with robotic controls could operate four or five mowers at the same time, much like a shepherd watching a flock of sheep.
And the robots will eat the grass and it will be good.
1.2 剪草機(jī)的發(fā)展
起初,羊吃草可以使草保持很短,并且比較美觀。
但是,這并非十分有效的修草方式。 因此,直到十九世紀(jì)三十年代,少數(shù)的草地?fù)碛姓呤褂瞄L(zhǎng)柄大鐮刀或者剪刀修剪草坪到合適的高度,使它們處于修整狀態(tài),。
隨后,英國(guó)人Edvin?Budding發(fā)明了用于造布工廠中的一種刀具。什么使他有這樣的想法并且制造一臺(tái)割草機(jī)?
在170年里,自從Budding發(fā)明了第一臺(tái)割草機(jī)以來(lái),草坪剪草機(jī)已從原來(lái)笨重的機(jī)器轉(zhuǎn)變?yōu)榫哂卸喾N特性和不同切割速度、精度的家用設(shè)備。
此發(fā)明也改變了住宅,公園和土地草坪區(qū)域的外觀。修剪草坪不再使用簡(jiǎn)單和老套的切割機(jī)器,再也不是局限于貴族間的行為。大多數(shù)中產(chǎn)階級(jí)也可以擁有健康,具有吸引力的草坪,提高他們的資產(chǎn)。
Budding的創(chuàng)意:
在十九世紀(jì)三十年代前后,園丁使用長(zhǎng)柄大鐮刀修整草地。為了產(chǎn)生最好的割草結(jié)果,應(yīng)該在一大清早或者深夜地面因?yàn)槁端兊贸睗駮r(shí)進(jìn)行工作。稍不小心就會(huì)由長(zhǎng)柄大鐮刀留下不開心的印記。
當(dāng)Budding的想法成為現(xiàn)實(shí)之后,可安排工人在方便時(shí)候削減草地。同時(shí),在1830年Budding和他的團(tuán)隊(duì)因?yàn)椴萜盒藜魴C(jī)獲得了專利。
“使用我的機(jī)器,人民可以進(jìn)行愉快的,有用的,健康的工作”,Budding在他的專利文件中說(shuō)。
機(jī)器制作是比較粗糙的。它的后面有一個(gè)輥?zhàn)雍颓懊嬗幸粋€(gè)切割的圓筒。機(jī)器把動(dòng)力從后部輥?zhàn)訚L筒傳遞到切割的圓筒。在大部分情況下操作困難,需要兩個(gè)人配合:一個(gè)推,另一個(gè)拉。
沒過多久,在Budding的創(chuàng)意上進(jìn)行了改進(jìn)。有馬或者其它馱畜拉的機(jī)器;用鏈子代替齒輪驅(qū)動(dòng)切割單元,輪子自己驅(qū)動(dòng)切割圓筒。
十九世紀(jì)七十年代,草坪剪草機(jī)曾經(jīng)變得那樣簡(jiǎn)單實(shí)用而且價(jià)格合理,以至于他們?cè)诿绹?guó)人美化環(huán)境中變得更必不可少。
草坪剪草機(jī)修剪草坪比人類自己修剪更加有效。在十九世紀(jì)90年代,剪草機(jī)開始發(fā)生改變,發(fā)明者和制造商把發(fā)動(dòng)機(jī)運(yùn)用到草坪修剪機(jī)。
在1890年,提出利用蒸汽的剪草機(jī),但是它相對(duì)較重,有噪聲,控制和調(diào)動(dòng)困難。就在世紀(jì)之交之后,使用汽油機(jī)的機(jī)器使用,也成為生產(chǎn)部門的主要生產(chǎn)對(duì)象。
強(qiáng)大的引擎能帶動(dòng)更多刀片并且更好的削剪。乘坐式切割對(duì)于切割高爾夫球場(chǎng)上草地時(shí),與一輛拖拉機(jī)配合組成整體的切割機(jī)。為了提高切割速率,割草機(jī)已變得必不可少。切割單元連接在割草機(jī)的前部--利用引擎剪草,或者連接在一輛拖拉機(jī)傳動(dòng)裝置的后面。
引擎裝置在剪草機(jī)上使旋轉(zhuǎn)的刀片更切實(shí)可行。引擎能提供足夠的旋轉(zhuǎn)動(dòng)力使刀片有效地快速地切割草地。當(dāng)引擎裝置變得較便宜和更強(qiáng)大時(shí),在第二次世界大戰(zhàn)之后變得更流行,而人們不斷的遷居也使更多人們擁有較大的草坪。旋轉(zhuǎn)式剪草機(jī)也一直保持價(jià)格低廉。
影響:
割草機(jī)也同樣有效。作為人或動(dòng)物拉或推機(jī)器的力量和耐力。這在19世紀(jì)90年代開始發(fā)生變化,因?yàn)榘l(fā)明家和制造商們都在尋找將引擎動(dòng)力帶到割草機(jī)上的方法。
一臺(tái)蒸汽動(dòng)力割草機(jī)在19世紀(jì)90年代引入,但噪音大,難以控制和操縱。在本世紀(jì)初之后,汽油動(dòng)力的機(jī)器變得可用,開啟了生產(chǎn)力的大門。
強(qiáng)大的發(fā)動(dòng)機(jī)可以推動(dòng)或拉動(dòng)更多的刀片,并提供更好的削減。割草機(jī)割捆的割草機(jī)在公園和高爾夫球場(chǎng)切割草坪時(shí)變得很普遍。隨著切割寬度和生產(chǎn)率的提高,騎馬割草機(jī)變得司空見慣。切割單元可以在后引擎割草機(jī)的前部或拖拉機(jī)驅(qū)動(dòng)單元的后部找到。
發(fā)動(dòng)機(jī)功率也使得旋轉(zhuǎn)葉片在割草機(jī)上更為可行。發(fā)動(dòng)機(jī)可以提供旋轉(zhuǎn)葉片足夠快的動(dòng)力來(lái)有效地切割草坪。在二戰(zhàn)后,隨著發(fā)動(dòng)機(jī)變得更便宜和更強(qiáng)大,輪轉(zhuǎn)車變得更加流行,而向郊區(qū)的加速遷移意味著更多的人擁有更大的草坪來(lái)維持。旋轉(zhuǎn)機(jī)械的制造和維護(hù)成本較低。
其它革新:
制造廠已繼續(xù)努力制造較容易使用并且提供一個(gè)更好的削減方式的剪草機(jī)。
機(jī)器由液壓驅(qū)動(dòng),動(dòng)力更強(qiáng)勁,園藝師操作精度更高。在草坪被切割后,新型剪草機(jī)能用收集裝置收集剪下的碎草,免去了工人耙草和清掃的工作。帶有氣動(dòng)輪胎的剪草機(jī)不會(huì)在草坪上留下壓痕并且允許剪草機(jī)橫穿草坪比如綠色的高爾夫球場(chǎng)。
通過使用控制桿調(diào)節(jié)輪子來(lái)駕駛一臺(tái)剪草機(jī),可以讓旋轉(zhuǎn)式剪草機(jī)到達(dá)許多常規(guī)的機(jī)器不能到達(dá)的區(qū)域,并且能穿越障礙在草地上各處隨意調(diào)動(dòng)。制造廠連續(xù)不斷地學(xué)習(xí)技術(shù)革新,看他們?nèi)绾谓ㄔ煲粋€(gè)較好的剪草機(jī)。
發(fā)展趨勢(shì):
如果你想知道你可能在未來(lái)的剪草機(jī)中能看見的,請(qǐng)你拭目以待。在草坪設(shè)備中的許多改進(jìn)源自于汽車工業(yè)。
“我們不得不等候汽車工業(yè)提出技術(shù)革新和改進(jìn)”,德事隆公司的草坪產(chǎn)品管理的副總經(jīng)理彼得說(shuō)?!拔覀儧]有他們做的數(shù)量大。相反,無(wú)數(shù)草坪剪草機(jī)在百年間才被制造”。
同時(shí),當(dāng)汽車已將更多計(jì)算機(jī)技術(shù)應(yīng)用到他們的系統(tǒng)中時(shí),草坪剪草機(jī)也是如此。
“計(jì)算機(jī)技術(shù)難以置信的快速和廉價(jià)”,先進(jìn)的剪草技術(shù)研究中心的主任戴納.羅恩說(shuō)。“可利用衛(wèi)星技術(shù)中突破,例如運(yùn)用全球定位系統(tǒng)( GPS )和遙感技術(shù),將使你確切地知道草地的什么地方需要修剪”。
那將不僅僅改進(jìn)你的工作效率,也減少對(duì)環(huán)境的負(fù)面影響,提高剪草質(zhì)量。
羅恩說(shuō):“你可以使用新技術(shù)來(lái)幫助你僅僅修剪需要修剪的區(qū)域”。
衛(wèi)星系統(tǒng)也能夠提高設(shè)備維護(hù)能力并且預(yù)計(jì)機(jī)器使用壽命。
John Deere的全球商業(yè)與消費(fèi)者設(shè)備部門的通信經(jīng)理Bob Tracinski說(shuō)“現(xiàn)在有越來(lái)越多的人談?wù)摿愎て?,它的趨?shì)是朝著設(shè)備的耐久性進(jìn)行設(shè)計(jì)”。
他說(shuō)計(jì)算機(jī)芯片 “黑匣子”安裝在剪草機(jī)中,來(lái)監(jiān)控對(duì)損耗與故障敏感的部件。 當(dāng)部件開始顯示疲勞的征兆或者損壞時(shí),芯片就能把信息傳送到一個(gè)能通知經(jīng)銷商的GPS衛(wèi)星。
Tracinski說(shuō)"經(jīng)銷商甚至在操作人員知道部件有問題之前在工作點(diǎn)外就能提前做出一個(gè)新部件。
因?yàn)樾l(wèi)星能夠檢測(cè)設(shè)備的每一個(gè)部分,該技術(shù)可以阻止偷竊行為。規(guī)劃公司可以利用它測(cè)繪工作的最短路徑,這將節(jié)省工作人員的時(shí)間。
Tracinski說(shuō)“技術(shù)是可行的,如何降低成本是當(dāng)下的唯一問題”。
靜音性和舒適性:
未來(lái)割草機(jī)將更環(huán)保,更舒適,更容易使用,并具有更好的安全特性融入設(shè)計(jì)。制造商將更加重視人機(jī)工程學(xué)設(shè)計(jì)。
隨著土地緊缺行業(yè)的勞動(dòng)力短缺。Tracinski說(shuō),人們需要更長(zhǎng)的時(shí)間工作,他們希望乘坐更舒適的騎行設(shè)備。這意味著像高靠背座椅和低噪音水平,控制適當(dāng)放置,東西顏色編碼,容易開關(guān)和開關(guān)。
公司正在繼續(xù)尋找割草機(jī)的替代燃料來(lái)源,以減少空氣和噪音污染。關(guān)注草坪割草機(jī)和其他草坪和庭院設(shè)備的排放對(duì)大氣的影響,美國(guó)環(huán)境保護(hù)署正在加強(qiáng)對(duì)小型發(fā)動(dòng)機(jī)的排放標(biāo)準(zhǔn),例如割草機(jī)上使用的小型發(fā)動(dòng)機(jī)。
“你會(huì)看到這方面的重大變化,”Lonn說(shuō)。割草機(jī)將有燃料電池而不是汽油或柴油發(fā)動(dòng)機(jī)。
電池和燃料電池將取得進(jìn)展。在這一點(diǎn)上,他們將能夠提供足夠的電力來(lái)修剪草坪,而不讓鄰居們從睡眠中醒來(lái)。
Whurr說(shuō):“噪音太低了,你甚至不知道景觀設(shè)計(jì)師在那里工作?!?
例如,金屬動(dòng)力(卡爾斯巴德,Calif.)與Briggs Stratton、TROO和TExPon達(dá)成協(xié)議,用于開發(fā)使用其鋅/空氣燃料電池的車輛。由燃料電池供電的單位可能在未來(lái)幾年內(nèi)可用。它們將是安靜和無(wú)排放的,并且應(yīng)該有足夠的功率以適應(yīng)正常的維護(hù)操作。 Tracinski說(shuō),該行業(yè)正在努力使這不妨礙景觀設(shè)計(jì)師的工作安全特性是割草機(jī)的一個(gè)組成部分。
Tracinski說(shuō),一些商業(yè)運(yùn)營(yíng)商繞過安全的趨勢(shì)是為了提高生產(chǎn)率。公司試圖以安全的方式進(jìn)行建設(shè),使之不被視為生產(chǎn)力的障礙。
同樣,制造商正在努力使割草機(jī)簡(jiǎn)單地操作,即使對(duì)于沒有經(jīng)驗(yàn)或機(jī)械背景的人。Tracinski說(shuō),勞動(dòng)力短缺意味著有可能掌握機(jī)械知識(shí),甚至說(shuō)英語(yǔ)。我們正在努力使控制裝置易于操作和學(xué)習(xí),以便工人立即準(zhǔn)備割草。
機(jī)器人牧群:
計(jì)算機(jī)還將創(chuàng)造更智能的機(jī)器,如機(jī)器人控制割草機(jī)。
Whurr說(shuō),他們幼年時(shí)就在那里。你可以在門廊上抬起你的腳,而割草機(jī)自己做這件事本身,制造商需要解決幾個(gè)安全問題,然后才可以自己發(fā)送機(jī)器。但是他們很接近。
Lonn說(shuō),離擁有完全自主的馬不遠(yuǎn)。機(jī)器會(huì)知道它在哪里,會(huì)知道如何避免碰撞。你可以提前計(jì)劃該做什么。而不是每一個(gè)騎著割草機(jī)工作的五個(gè)工人,一個(gè)機(jī)器人控制的工人可以同時(shí)操作四或五個(gè)割草機(jī),就像牧羊人看一群羊一樣。
機(jī)器人會(huì)吃草,它會(huì)很好。
