Good for you, jackjack99168. It's good that you have gotten a tractor without the expense, but also good that you're able and willing to learn how to use it. This board will be invaluable as you begin the process.
While I had been around motors and machinery my whole life, I had never had the opportunity to operate anything diesel or with hydraulics. It opened a whole new vista and it has been fun. Well, aggravating at times but that always passes when success appears. You'll be surprised at how much you can learn from the "brilliant minds" on this board. And, I mean that term. Many of the members know these machines inside and out. And, the remarkable thing is...they try to help us learn and get out of pickles because we don't know!
Aside from all of the processes that you will encounter with your new machine, be sure to learn and keep up with the maintenance of the fluids, filters, etc. That effort will probably make your machine last longer. Try not to be tempted by buying "off brand" parts/filters. It's tempting, for sure, and some of those purchases are OK, but, for the most part, stick with the OEM (original equipment manufacture). Saving a few dollars may cost more in the long run. Then, do not try to ask that little baby to do more than it is designed to do. Like us, everything has limits. Keep in mind that this particular model of Kubota tractors seem to be a bit "tippy," so avoid working horizontally on slopes. It's never good to learn the hard way!
So, hang in there. It's a process. And like the tortoise and the hare, try not to rush the intake of information. Things take time, especially if you are not familiar with machines yet. I hope to read of your successes along the way. I've had a few myself!
