I searched through countless old threads and couldn't find anything that matched my problems I'm having so decided to start a new one. Have had my new holland 175 track machine for years and love it. It's all joystick operated, starts and runs like a dream every time. My problems first started when I was driving along and the seat belt light came on and it stopped dead in its tracks although seatbelt was still fastened. This has happened twice. lately when I am operating it, all works fine for about 20 minutes and then I lose all bucket and boom function. I can still drive fine, just can't raise or tilt bucket. Sometimes I am able to undo seat belt or shut it off and restart and will work again but not usually. If I let it sit for awhile, come back the next day it works every time for another 20 or 30 minutes. Seems like an electrical issue, maybe a seat switch or seatbelt switch. But the fact that it seems to happen only after it's good and warmed up, and then always works again after I let it sit for awhile doesn't really support that theory. side note- I live in an extremely rural area and have begged every mechanic I know of to tackle this and they are either too busy or not interested, so as the old saying goes ...If you want something done right..... Thanks for any feedback.
