Q: My son just turned 3 and he is obsessed with the movie Up. We took him to see it and ever since he has been asking for balloons and running around yelling quot;up up and away!quot; He has a cardboard box quot;housequot; that he quot;fixesquot; with his plastic tools, last week he took one of his balloons and asked me to attach it to the top so it was like the Up house. Then he ran around all day yelling quot;So long boysquot; out the window. Too cute!: My two year old nephew has a mind of his own too. He knows every type of construction vehicle created by man. Excavator, Front end loader, backhoe, cement truck and if you say look see the excavator he will well let you know what it really is. He also knows everything created by John Deere like the gator and stuff. His mom takes him to demolition sites so he can watch these machines go to work. He has never said the word mad. Instead he asks him mom if she is angry. The other day he just started teeing on the floor so his mom got upset and he said momma are you little angry or big angry. Now that he is fully potty trained he looks at his number 2 and lets us know what it looks like. Such as an ice cream cone, a snake, a mushroom. Every week he comes up with something new! I guess it is good he hasn't seen up yet!

Q: How do you determine the bucket capacity of excavators when you know the type of excavator?: Model is 35, that is, 3.5 ton bucket capacity of about 0.11 cubic metersModel is 60, that is, 6 ton bucket capacity of about 0.3 cubic metersModel is 120, that is, 12 ton bucket capacity of about 0.5 cubic metersModel is 160, that is, 16 ton bucket capacity of about 0.65 cubic metersModel is 200, that is, 20 tons, bucket capacity of about 0.8 cubic metersModel is 220, that is, 22 ton bucket capacity of about 1.1 cubic metersModel is 240, that is, 24 ton bucket capacity of about 1.2 cubic metersModel is 270, that is, 27 ton bucket capacity of about 1.5 cubic metersModel is 300, that is, 30 ton bucket capacity of about 1.6 cubic metersModel is 400, that is, 40 ton bucket capacity of about 1.9 cubic metersModel is 250, that is, 45 ton bucket capacity of about 2.1 cubic metersThe above generally refers to the natural excavation pileDifferent brand excavator models are differentPC200-8, PC stands for the Komatsu excavator series, 200 represents the 20 ton class, and the -8 represents the new generation of algebra.Carter 306, 3 represents the Carter excavator series, 06 represents the 6 ton class, and the new algebra is represented by ABCD

Q: If so, what is your favorite episode? Also, why is that your favorite epsiode?Mine is the one that has to do with the worlds largest machines or something like that, I just can't remember the actual title. But my favorite part about that episode was when they talked about the bucket excavators. They said the largest one can hold 2 Grey Hound buses in the part that holds the dirt.: nope i usually just watch the ufo shows on there

Q: I have a John Deere 30 mini excavator. It is roughly 1987 vintage. Product ID is CH0030D001044. Im looking for a new/used front window. It is curved glass, 2 piece, top slides down over the bottom. Any help locating the glass would be greatly appreciated. Im also looking for replacement tracks for this machine. It currently has steel tracks, Im looking at upgrading to rubber tracks. Will rubber tracks install on this machine easily? Do I need any extra components to make the switch? What is a reputable company for aftermarket tracks? Thank you very much.: if your in california, try myers ward in fresno. if your in the midwest, use the yellow pages.

Q: perkins engine: I know it is a 22 hp and only manufactured for england but the cc rating i don't know here is a cat site maybe you can find it

Q: A few months ago we had some excavation work done by a licensed and insured excavator in our back yard near the well about 15 feet or so. He removed a lot of ledge and tree stumps and buried them to level yard. With in a week we got a terrible odor and bacteria. We have treated the well twice and the bacteria keeps returning w/ awful smells and our water tests are all over the place. We had great drinking water prior to work done. Because the bacteria has returned once again the well may be damaged and we are looking into that now. If the well is damaged does his insurance cover our damages? How do we find out???: His insurance should cover any damages he caused. However, you will need to show that he actually DID cause the damage, if it exists. Right now, all you have is the fact that your well seemed to go bad shortly after the excavation work was done. That's not sufficient proof. You will somehow need to show that his mechanical actions caused this situation. It won't be easy.

Q: Hi not sure if this is the movie bullitt or not but it has a really long police chase, at the end the police line up excavators and bulldozers across the road and the guy being chased rather than stopping, slams straight into them? So is this bullitt? Or another movie? Cheers: You okorder /

Q: okay so my first question is, do you need the achievement from the DLC with the Shang gru la (or however it is spelled) zombies map in it? Also how.do you time the excavator perfect so the egg guy goes onto the satellite after you hit em: So i be attentive to that map is particularly stressful with those escavators they ar set to random on the place they are going to hit yet you ultimate possibility is to make as plenty funds as you are able to by utilising the 2d or third around so which you will turn on the flexibility verify u save a crawler so u can play the sam says interest and even have the scientist do each thing yet whilst the escavators come and it does not hit corridor variety six only restart it because of the fact its going to in basic terms get extra sturdy in case you do the beginning up by utilising around 3 the escavator comes by utilising around six or seven I even have all of it carried out by utilising around 12 plenty extra perfect and much less puzzling in case you like halp I do supply help to those that want it I do it for acquaintances all the time I even have all the easter eggs my GT MATT TR0P0LIS the O's are zeros only message me in case you or everybody desires help

Q: Bench tested altinator,it's good,new batteries,new belts,checked fuses, still only 24.8 volts at the batteries.Should be around 28 volts with engine running. Display in opperators cab reads quot;charging problemquot;. Is there a relay I don't know about?: yes yu may have an external regulator fitted , some times its under the seat , maye be elsewhere , might be near fuse box , should be bigger than a normal relay , will have alt written on it , probably black and plastic , yu can try and call dealer parts section and ask them if there's one on yur machine , yu will need serial number of coz , if its imported serial number wont be any good , is the charge indicator light on the control panel working , did yu check the fuses ?........ move them around in case there's a corroded connection , how many wires on back of alternator ?.......should be big red one , and at least one small one ( signal wire ) make sure this is ok , make sure wiring harness from engine to chassis is ok , yu might find wiring diagramm on internet , this will show external reg , are there any small wires connected to the big ht ( high tension ) wire on the battery ?.......is there an inline fuse fitted there ?? .....is corrosion a problem with any part of the harness ? dont be afraid to cut open the harness with a box cutter knife if yu think yu have a problem , its ok it wont bleed , just retape back together in a proffesional manner when checked out ,
