I know that a joy stick would be the way to go but they are mostly found on the larger and newer dozers. I think Komatsu makes one in the D21 series, but I think it is still a grey market dozer. My local Komatsu dealer would not commit himself to weather he could get parts. I have got to stick to the smaller dozer. John Deere and Case no longer make the 350's. and I didnt like them when they did. My HD4 is in the same size weight and hp catogory and I feel is a much better dozer. I sort of got into the dozer work by accident. I had run a different type of business for 30 years and about ten years ago I built my own house. I had three different dozers out to do a one hour job at different times. Larger than I could wo with my tractor and scraper blade. The first one he spent 45min working on his tracks to keep them from falling off and 15 min of work. And I know that no dozer operator can just do a one hour job. The time and cost of loading it up, trucking it to site, fuel, license, repairs and I realize that most must have a 2 or 3 hr minum. The second dozer operator couldnt really decide between uphill and down hill. I wanted some grading done so the water would run away from my house and after paying him, it was still high so I had to cut it out with my tractor and blade. The third one was for a 8 hour job and I have moved more dirt with my tractor and a box blade with a ripper in the same amount of time than he did with a JD450. So I still had more work that needed done and another property that needed some and it was the type or work that could not be done all at one time, so renting one was not practical. I started thinking about getting a older dozer, the smaller the better because I could haul it on my skid steer trailer and did'nt want to buy a larger truck at the time. I ran on to a MF 200B that had a ripper on it. It weighed about 9000lbs. I had to do some work on it. After getting it in good shape I would use it from time to time as needed. First thing I knew, people were asking me if I could come out of Sat. or after 5. during my weekly job, and do a small job that other dozer operators would not do. So I started doing small jobs, (driveways, cleaning up fence rows, pileing up brush, just small light jobs. I was just about at retirement age but could never just sit by. I kept getting more jobs. I couldnt get parts for the MF200 so I sold it and make a good profit. I bought a Case 350. It wasnt near the dozer the MF was. It doesnt have steering clutches, just a brake band to lock one axel up. I kep it for a year or two, then a private contractor asked me to to some dozer work for him, so he could move his crew on to another job. This worked out fine for me and him too. He didnt have to pay all the benefits, and taxes. So I kept the little dozer pretty busy and just retired and started up doing another line of work. I didnt like the Case 350 but there are just not any small dozers made in the US any more. I ran on to a old Allice HD4 (probably around 1963) It was in excellent shape for a dozer of that age. I bought it and I really like it over the other small dozers. But as I age, you start thinking of ways to ease the pain at the end of a 8 hour day on a dozer. I had heard that Allice Chalmers made some 653 with pedal stee, I was curious to know if any one had ever operated one of them. I have seen a few of them with a blowed motor or final drive and I could buy one of them pretty reasonable and some people have told me that most of my HD4 parts will fit on it. Other than that my only alternative is a little Mitsbushi or Komatsu. I see too many people with Case 450 and JD450 sitting around and not busy. I know that my jobs are limited with that small of dozer but I have found a nitch that was lacking in my area and I have made money going that route. Any more input is appreciated.
