ENGINE DETAIL
The John Deere 8220T features a powerful 6-cylinder turbocharged diesel engine with an 8.1L displacement, providing a rated power output of 225hp (ECE R24) and up to 250hp at maximum power. With a high compression ratio of 16.5:1, it excels in fuel efficiency and torque delivery, essential for heavy-duty applications like tilling and plowing. However, potential challenges include the need for proper cooling management due to the coolant capacity of 35.9qts, which may limit operation duration in very hot conditions without adequate cooling systems.
