    Scary D9 Loading

    I agree. Without the blade on, it is way tail heavy. Metal on metal is slippery.

    631E's in Castle Rock, Colorado

    I was on a job in AZ where we were over loading 657's and 637's all day long with farm field dirt. The job was going great and the bosses were loving all the production until a draft arm on a 657 was broken. They put a stop to the overloading after that.

    Komatsu D58P-1 Dozer (What are your opinions?)

    I know I am a little late on this one, but from my underestanding a "P" model is not a "gray" market machine. I am currently working on an "S" model Komatsu track loader that is a "gray" machine. I rebuilt the UC and engine on a D41P last year and thought it was a good machine when I broke the...

    631E's in Castle Rock, Colorado

    When is Monks gonna replace those 631s with 637s? I realize that times are tough to be out buying new scrappers, but why buy a new D10T pushcat when they could have bought a couple of 637s and not had to push them?

    What Size?

    I live in Stephenville TX. One of my clients has a JD 4440 that he pulls a 7 yd scrapper with. He has no problems in our hard dirt as long as he takes his time and runs long cuts. He says that if you jam the pan in the ground it will just spin the tires. The 4440 is a 2 wheel drive...

    twin engine scraper throttle?

    I never minded the air throttle on the rear engine when I ran a 627. I am a bit of a "hack" and only use the rear engine when I could have it floored. I did not like the air throttle on a 623 F that I used to run. That was when I needed some precision, and it seemed like I could never quite...

    Teach me how to test drive a dozer!

    I can't add to much to what was already said. I did a complete UC replacement on a Komatsu D41P for a customer last summer and it cost $14,000. So the cost racks up quickly. Take a look at the breather tube from the motor. I don't know where that one is located, but if there is a large...

    call before you dig!!!! needs help lol...

    I have dealt with some really dumb and lazy locators as well. But what about the operators that don't pay attention to the stakes and marks. I was checking grade on a street widening project a couple of years ago and there was a Fiber optic running under the area we were cutting down to...

    farm dozer?

    I rebuilt the under carriage and engine on a Komatsu D41-P this last summer for a customer of mine. I got to try it out after. I was quite impressed with the power to weight ratio. The controls are easy to learn and very straight forward. The engine is a tried and true Cummins 5.9 L like in...

    cab or no cab

    If I am going to operate a machine all day long, I prefer to have a cab. But here on my ranch, I have a few John Deere tractors and a John Deere 450 dozer that are open. It works for me, because I don't have to manitain the A/C. Back when I was operating in AZ the cabs and A/C were...

    Motor-Grading Techniques

    I learned how to run a blade the best by "checking grade" for some really good operators in AZ on the big developements out there. I saw all the tricks and then when it was my turn to operate, I had a huge advantage over the other new guys, cuz I paid attention to what I had seen. Practice...

    California big dirt scraper operators

    I was an equipment operator in AZ, I worked for Rummel Construction. We had 14 657 E's while I worked there. Those are pretty fun to operate, but I wasn't a regular in them
