Q: Good, bad or other?: I think it is yet to happen

Q: ok I know i have seen this question before but everyone keeps comparing it to sand. Well after this stuff dries it is solid and not like loose sand at all. So i guess my question is has any one used this and have they had any problems with it? The guy at the pet store swears by it but i am always a little leary about taking in their opinion on anything as they just want to sell me stuff (although he did let me feel the floor of one of the cages he had it in and the stuff really does dry as hard as a rock) Any help would be appreciated: No it's perfectly fine. But only when dry

Q: Its likea a claw thing,,, similar to a crane but looks like a claw big machines used in construciton~: excavator

Q: We have a farmer behind our house and whenever he floods his field for multiple days at a time it gets into our basement due to waterlevel issues. We have a sump pump but it is coming in along some of the walls of the basement and getting carpet wet. WE have fans on it right now and it should be ok for now. We've tried talking to the farmer before but he doesn't give a crap because he is an old angry man ( i hate him so much) So I am wondering if there is anyway we can make him only water every 3 days or so because he won't listen to reason. It is also causing problems for some of our neighbors so would it be possible to get like a petition and turn it in to the city? would that work?or what else can we do!?!?thanks!: There's probably nothing you can do to make the farmer cut back or stop watering if the watering is part of earning his living. What you need to do is hire an excavator to dig out around your foundation. There is a product that is sprayed onto the exterior foundation walls - looks like rubberized tar - that will seal your foundation against leaks. This won't be cheap, but it will be a permanent fix. It would be a good idea to do this anyway. When the farmer quits farming, you may still have water issues in your basement unless you seal the basement walls. This should have been done when the house was built, but it's water over the dam now. I don't know if applying a sealer on the inside of the basement walls will work. The water will tend to push the sealer away from the interior wall. But you can try a small area to see how it works.

Q: What exactly do they call this type of mini 4 wheeled tractor? like not the brand but category i think? like how some are called excavators: skidsteer

Q: So I got a new job and today was my first day. It was horrible, I got no training and it is a pretty dangerous job, it's installing sewer and drainage piping. I don't mind hard work, but I had no idea what to do and felt useless. My co workers are either assholes or idiots. My foreman is nice, but he hasn't trained me to do anything and expects me to figure everything out on my own.So I'm thinking of just not showing up tomorrow. I got a call about another job today and did not answer because it wasn't safe to do so at the time, but they left a message and asked me to call back, so I think I will tomorrow. Thoughts?Also I can't go in tomorrow and call about the other job because I'm always in a trench with excavators all around.: Just don't show up! Your life is worth more than a job, this job. Go for the other job! Your safety is all that should matter to you.

Q: What does PC200 excavator mean? What does PC mean? What do you mean by 200? How big is the bucket capacity?: PC200 is Komatsu excavator. 200 machine weight 20 tons. It should be 0.8 parties

Q: Any help would be greatly appreciated........The Deutz f4m1008 engine on my mini-excavator will start fine and it will run for about 5-10 minutes and then starts sputtering for 15 - 20 seconds or so and then it konks out. I can restart it again, after a few minutes. Then, after a shorter 2 minutes of running, it konks out again. I can do this ten times in a row if I wanted to and it does the same thing, run 2 minutes then quit. The fuel cap was removed to check if it was a vaccuum problem and that didn't help. There are no fuel line obstructions. I replaced the fuel filter and found that one of the stems on the fuel pump (I assume it is the pump on top of engine) was loose. I was happy thinking that I had found the problem, but no such luck. Anyways, the radiator is full, as is the oil. I added additional conditioner as well as anti-freeze in case of moisture. I am wondering if the solenoid for the fuel cut-off is malfunctioning.Thank you in advance for any help.: Tank screen or air in lines.You can have bad diesel(water in fuel).

Q: I'm looking on behalf of my company - who needs to get tracks and undercarriage parts for some Bobcat machinery.: I have had good luck with a company called Gabberdeen. They have everything. I have a 331 and I got my whole undercarriage and tracks for them from CHEAP. Find them on the internet.

Q: Im looking for new tires for my 1987 Suzuki 250 QuadRunner 4x4. I came across some a tire called the Duro Excavator HF274. It is exactly the kind of tire that I want because it is good for mud and snow. It is a 4ply tire. But what im not sure about is if it might be to heavy for my quad and if the treads are going to be to agressive for the transmission on my quad becasue it is only a 250cc.: It looks like a good tire to me. The four ply is a plus, because you don't have to worry as much about puncturing a tire.
