Function Description:
The New Holland T4.80LP, T4.90LP, T4.100LP, and T4.110LP tractors are designed as versatile agricultural machines capable of pulling, carrying, and powering a variety of mounted or towed equipment. They are intended for a wide range of farming operations, including tillage, planting, harvesting, and material handling, within specified physical limits. The manual emphasizes that the tractor is a "one man operated vehicle" with a single operator station, and no other people should be on or around the tractor during normal operation. It also highlights the importance of using only manufacturer-approved attachments and software to ensure safe and predictable behavior.
