I'm looking for a planetary gear assembly designed for a small backhoe. The gear assembly should be compatible with a 1/3 cubic model and meet the necessary specifications for durability and performance in heavy-duty applications. Could you provide me with details regarding the available options, including pricing, lead times, and any certifications or quality assurances? Also, if you have any technical documentation or compatibility information, that would be greatly appreciated. Thank you!
