Hi Guys. I'm new to this forum. I just purchased my first tractor in March. I love it. It's a Grand L6060 50th Anniversary edition. I just completed my first 50 hour maintenance and everything went great (except for the paint holding on the HST filter). I was cutting with my flail mower and the tractor all of a sudden came to a crawl and then cut off. It had only done this once before and I cleaned the filter and it worked fine after that. I cleaned the air filter again (I thought good) and it has now happened again. Does anyone have any idea what the issue could be? Thanks in advance for any advice or information given.
