I went to look at a kubota kx 121 last nite. This machine looked well taken care of. Pretty tight for 2000hrs all paint looks great. Everything worked even the a/c 2 things I noted that I need some help on. After putting the blade down I swung it around and tried to use the hoe to lift the back end off the ground so that the whole machine would be elevated and I couldn’t get the one end up. It seemed to push a little but not able to lift up the whole machine. The owner got in it because he was a bit annoyed that something may be wrong. With his attempt he was able to get the machine fully lifted a couple feet off the ground but it seemed he did it by dropping the bucket to the ground as close to the cab as possible and then pushing the stick outwards therefore lifting the machine up rather than putting the bucket down say 7’ out from the cab and then just lifting straight up. Is thisjust my lack of experience on these machines. Or Is this something showing weakness in the hydraulics? If so is there a better way to do a test before I hand over any$$. The second thing I noted was turning left or right at a stand still it didn’t seem to just pivot freely. I wasn’t able to just spin in a full circle. Going forward and reverse were fine and the low and hi speeds worked it just seemed to lack power in rotation. Again my lack of experience? Or should the machine just pivot on a dime when pulling the sticks opposite of each other. Please help with any other advise on what to look for as this is my first machine.
