I've had my MT125 for exactly one week now, put 12.5 hours on the gauge.. used the backhoe to dig a hole big enough to park a VW bus, have been using a boxblade to flatten and level an area as big as a basketball court getting ready to make a new shop... only very minor issues.. couple of missing circlips on the backhoe, one hose chaffed, fuel gauge always says full.. Came with a hand full of parts I have no idea what they are.. no real issues so far...
Those handful of part may be for your 3 point hitch. I had a missing lynch ring pin that goes to the front end loader.
