I'm interested in purchasing an 80 horsepower tractor and would like to gather some more information before making a decision. Could you please provide details on the models you have available in this horsepower range? I'd appreciate specs on engine type, fuel efficiency, and any additional features that may enhance performance. Also, let me know if there are any attachments or optional equipment that can be bundled with the tractor. Additionally, it would be helpful to receive information on pricing, bulk purchase discounts, warranty options, and lead times for delivery. If you have any promotional offers or upcoming models that might fit my requirements, please share those as well. Looking forward to your prompt response so I can evaluate the options and proceed accordingly.
