Power to weightThe power to weight ratio in these larger 6R series machines is very impressive. Both the 6230R and 6250R weigh in at 9.3t and have a maximum permissible weight of 15t. The 6250R has a rated engine horsepower of 250hp and a maximum engine horsepower with IPM of 300hp. This provides 1hp to every 31kg, something that’s not too often heard of in the industry, thus making this tractor the most powerful in this weight class.
