\"7f4781b0[1]\"<\/a><\/p>\n

It has handled my highly sloped 1000m\u00b2 lawn for seven full seasons<\/strong>, with some minor repairs outside the warranty along the way.<\/p>\n

<\/p>\n

It has been working on a lawn, that was far from flattened, and on steeper slopes than the manual promised, it was expected that this could cause issues.
\nYet there have been periods where it have been running over a month without any user interaction what so ever needed. And when it was needed, it was typically the steep slope, or the dog that had left a too large stick.<\/p>\n

It has now been given to one with a flat lawn, where I expect it can run for years. And has been replaced with a newer model 330X capable of handling steeper slopes. See review<\/a>.<\/p>\n

The one thing that set this apart from the competitors is the silence. It is so silent that I do not even bother to turn it off when I have guests.
\nIt is REALLY great that you can be sure that neither neighbours or anybody else will be disturbed while it is working.<\/p>\n

Here is a video example from my review of TZ70<\/a> that includes an Automower:\u00a0 https:\/\/www.youtube….QKQpqbwQc?rel=0<\/a>
\nIt is its 330X successor, but the sound level is almost identical. Note the level compared to the birds, the dog chewing a bone, and the car passing on the other side of the house about 45s in…<\/p>\n

They got models suited for minor (and less sloped) lawns as well, based on the same technology, that I assume works equally well.<\/p>\n

It has been quite cheap in usage. Making some measurements, I estimated that it have used about 100kWh a season, for 1000m\u00b2, and I give it a set (\u2248\u00a32) of three new ‘razors’ and screws each month.
\nHint: ALWAYS replace the blade-screws along with the blades, it is a real hell when the blades cut the screws (and they will over time), as it can be really tough to remove the tiny rudiments from the disk. So do NOT get stingy and try to save a few pennies here!!<\/p>\n

Below a letter in Danish sent to Husqvarna with praise and suggestion on how to make this great mower even better.

Ad AutoMower 230ACX<\/p>\n

Til Husqvarna<\/p>\n

Jeg er den lykkelige nye ejer af en AutoMower 230ACX. K\u00f8bt hos SMK i Svendborg.<\/p>\n

Er p\u00e5 alle m\u00e5der gl\u00e6deligt overrasket over denne.
\nEr imponeret over hvor p\u00e6nt et arbejde den laver, p\u00e5 trods af at der ikke er intelligens der l\u00e6rer den hvordan havens form er.<\/p>\n

Har dog et par helt simple forbedringsforslag, blandt andet af sikkerheden, der ganske let kunne g\u00f8re den endnu bedre. De fleste kan laves som software, og andre tror jeg kun kr\u00e6ver meget sm\u00e5 elektriske \u00e6ndringer.
\nDet eneste jeg beder om for dette er at hvis I indf\u00f8rer disse \u00e6ndringer da at modificere min med disse ogs\u00e5.<\/p>\n

1) Simpel tyverisikring. Lav et ‘Flyt’ punkt p\u00e5 menuen, der kr\u00e6ver indtastning af pin. Hvis dette IKKE er valgt, skal den (selv hvis man ‘slukker’ den), n\u00e5r den kommer uden for sit loop (eller dette slukkes fx ved klip af ledning) efter f\u00e5 sekunder begynde at beepe\/hyle svagt med STIGENDE intensitet med tiden.
\nS\u00e6ttes den ned indenfor loop, eller den t\u00e6ndes og der tastes pin, skal den holde op.
\nDen nuv\u00e6rende ‘tyverisikring’ sikrer kun at den er ubrugelig for tyven efter det valgte antal dage, men g\u00f8r INTET mod at den faktisk bliver fysisk stj\u00e5let! S\u00e5 hvis ikke tyven ved dette st\u00e5r han med en ubrugelig klipper, men jeg har mistet min…
\nDETTE ER VIGTIGT, OG REN SOFTWARE\/FIRMWARE!!<\/p>\n

2) Sikkerhed. Det ville v\u00e6re smart hvis I kunne lave en elektrisk bremsning af rotor enten ved kortslutning, eller passende lille modstand, eller endda str\u00f8m retur til batteri.<\/p>\n

Dette b\u00f8r ske ‘omg\u00e5ende’
\n2a) hvis et eller begge drivhjul slipper jorden. Fx hvis nogle l\u00f8fter den, eller hvis den v\u00e6ltes p\u00e5 siden.
\n2b) hvis man slukker den p\u00e5 kontakten<\/p>\n

3) Den registrerer ganske fikst hvor meget str\u00f8m den bruger til at lave selve klipningen.
\nDet bruger I PT til at lave spot klipning. Dette kunne med fordel g\u00f8res i en simpel archimedisk spiral frem for den komplekse firkant- spiral, der giver mange 90 graders drej, og derfor l\u00e6gger pl\u00e6nen un\u00f8digt ned.<\/p>\n

4) Akkumuler den opsamlede viden om klippe-str\u00f8mforbrug fra en tur, til et genemsnitsstr\u00f8mforbrug.
\nVed hver sampling :<\/p>\n

MeanCurrent = MeanCurrent+(ActualCurrent-MeanCurrent)*dT\/T<\/p>\n

S\u00e5 ville den efter en tur vide om den har klippet meget eller lidt.
\nHvis lidt, ville den kunne vente l\u00e6ngere med at k\u00f8re ud igen, da vi s\u00e5 nok er i en periode med mindre v\u00e6kst.<\/p>\n

5) Alternativt\/supplerende til 4), tilbyd en menupunkt med timer justeret med \u00e5rstidsvariation. Hvor den baseret p\u00e5 datoen k\u00f8rer l\u00e6ngst om sommeren hvor v\u00e6ksten er st\u00f8rst, og mindre om for\u00e5ret\/efter\u00e5ret. Den kan begynde senere p\u00e5 dagen om for\u00e5ret\/efter\u00e5ret for at forhindre at k\u00f8re i dug.<\/p>\n

6) En fugt-sensor, s\u00e5 den ikke k\u00f8rte ud i v\u00e5dt gr\u00e6s. B\u00e5de til h\u00e5ndtering af regnvejr og dug.<\/p>\n

7) Tilf\u00f8j automatisk h\u00e5ndtering af sommertid!!<\/p>\n

8) Et kantklippe-mode hvor den engang i mellem (frekvens valgbar i menu) fulgte kanttr\u00e5den s\u00e5 langt over tr\u00e5den som den nu var indstillet til (og kan g\u00f8re uden at ramme noget) hele vejen rundt. Hver anden gang hver vej rundt.<\/p>\n

9) N\u00e5r den k\u00f8rer p\u00e5 tv\u00e6rs opad en skr\u00e5ning s\u00e5 overkompenserer den s\u00e5 den ikke laver ret linie. Det har n\u00e6ppe betydning, men blot til orientering.<\/p>\n

Ting der kr\u00e6ver lidt mere<\/p>\n

10) Ved ikke om det vil virke i praksis, men har I pr\u00f8vet at under hvert blad montere en ‘kam’, s\u00e5 kun noget tyndt som gr\u00e6s kan ramme selve sk\u00e6ret?
\nDette t\u00e6nkt for at reducere risiko for personskade, eller at knive rammer fx sten, nedfaldne grene, eller efterladt leget\u00f8j.<\/p>\n

11) Den er ikke god til at detektere om den kravler op ad en skr\u00e5 grund, eller skjoldet bliver l\u00f8ftet fortil, fordi den har ramt fx en skr\u00e5 rod eller sten. Selvf\u00f8lgelig kan man fjerne disse\u00a0 forhindringer for den p\u00e5 forh\u00e5nd. Men en ret simpel \u00e6ndring af skjoldets hjuloph\u00e6ng kunne g\u00f8re at den kunne f\u00f8le om BEGGE forhjul l\u00f8ftede sig. Dette kunne man lave ved at lave en lang u-b\u00f8jle der holdt begge forhjul, men som kunne glide lidt op og ned, og s\u00e5 to sm\u00e5 f\u00f8lere i skjoldet i hver side hvor b\u00f8jlen st\u00f8ttede. Hvis begge f\u00f8lere slap, vidste man at forhjul havde sluppet jorden, og der skulle bakkes.<\/p>\n

12) Passive vandrette st\u00f8tte-hjul i de fire ‘hj\u00f8rner’ af skjoldet s\u00e5 den ikke ridsedes\/(eller selv ridser) n\u00e5r den k\u00f8rte langs fx mur\/steng\u00e6rde\/stakit…<\/p>\n

13) I kunne tilbyde alternativt udformet skjold som en skildpadde. Det ville give den en mere hyggelig fremtoning, n\u00e5r den t\u00f8ffer rundt i haven. Sensor\/oplader ligner jo n\u00e6sten et lidt indtrukket hovede allerede. \ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"
