It sounds like you are describing the Kubota LA2255 front loader attachment for the Kubota M6 Series tractors such as the M6.101 and M6.141. This front loader requires 74 horsepower and has a weight of 1.1 tonnes. It seems that the front loader may have some minor issues in the game, such as hydraulic sounds and visual glitches, but it is still usable without any major impact on gameplay.
Additionally, you mentioned leaving your trailer mod for use with this front loader. If you are looking for a mod that includes the Kubota M5 and M6 pack to convert your trailer for use with the Kubota front loader, you may want to search for available mods or reach out to the modding community for assistance in converting your trailer.
Overall, it seems like you are looking to enhance your farming experience with the Kubota front loader attachment, and with some minor adjustments, you should be able to continue using it effectively in the game. If you encounter any specific issues or need further assistance, feel free to ask for help in the forum.
