Looking to purchase D8k

New here, I live on a farm, and I have been working in construction for 5 years so far, want to start myself a business. Looking at purchasing a piece of heavy equipment for this, and then move on to more. There is two pot ash mines that are going to be going up in my area locally and want to get on the ball before it's too late. There is a 1977 D8k for sale, they want $28,000 for it. Here's a link to the dozer. http://ift.tt/1fEmn3f



I have a few questions, i have read that they have cracking head problems if pushing on steep grades that the water will go to one side, and when you flatten out the coolant cold shocks the head? And with the transmission sucking air and becoming a run away, but that is remedied by adding an extra 5 gallon pail of fluid tthe transmission.



Is there anything else one should know about these older units? Other then they are one of the best units you can buy?



What about transportation? I will need to move the unit quite often, i have access to a 500+ horsepower kenworth that is set up for wide loads, but no trailer. What kind of trailer is best? I watched this video and it looks like the lower the trailer the better. http://ift.tt/1fEmn3j



Tri axle trailer is a must probably with weight of the dozer. Was looking at this trailer http://ift.tt/1fEmn3l and this trailer http://ift.tt/1fEmn3n



Let me know what everyone thinks.
