Its a good little dozer. It shows 1400 hours on the meter but I can't verify that. It was a pit dozer used at a generating plant pushing cinders. As you can imagine the acid from the cinders done a number on the under carriage. It ran strong and had new paint so I bought it. That was three years ago and since then I have pretty much rebuilt the whole dozer except for the motor which is in good shape. It really is a tad small for what I am doing with it, building a four acre lake. Kind of like digging a well with a spoon. I am in no hurry and love pushing dirt. I am building the lake in two sections and the main part is done and roughly 3/4 full of water. Soon as weather permits we will start on the second section. You might wonder how you build a lake in sections, Snorkels! Seriously we left a high point and will start a second dam. Once the second dam is finished we will break the seal with the hoe allowing the water to drain into the new section. Then we can work on the high point of the old seal. Clear as mud, right. We will have roughly 4 surface acres when done with two large islands. Its been a good relief valve for me and allowed me some quality time with my 16 year old son. He would be on the Kubota ripping while I pushed. I will truly be sorry when the project is done but we will find something to do. Big project, small equipment, three years in our spare time, but would do it again in a heart beat. This dozer is actually our second. We had a Dresser T500C, but it was too worn out and old. We had a little trouble getting parts due to the age. I suppose stubborness had something to do with using the small dozer, people telling me it would not do the job. I knew it would but just take longer, been messing around with equipment a long time, just never owned them (dozers). The Kubota 4610 is no slouch in moving dirt and has been invaluble in the project along with other chores. Sorry, I have rambled on too much. What kind of project are you working on with your D45A. That is a nice sized dozer, should be no problem getting parts as long as your wallet holds up, They can get expensive. My only advice is to service the machine regularly and keep on top of the filters. Blow out your pre-filter and radiator quite often. Hope to hear back, keep pushing dirt, it keeps you young.
