Few "Pulling Tractors would do well doing "Field Work..but I'd bet that 830 would be at home under "normal loads" for an 830...
Wonder what the hp WOULD BE FOR THAT 830 AND 720..??..!!!!!!
They sure don't Pull-Down..!!!
A fellow here that pulls in Plain City, Ohio has a JD 70 D that is one that is just a pleasure to hear and see pull... it has that Crisp throttle response..even at at Idle, of a good sharp "Gas" JD and does NOT smoke a lick under what would be a load a normal 70 would be over-loaded and acts like it has not even been hooked to the sled...!!! I know he said it had a different Cam and the Injectors were re-worked, with a Higher cracking pressure...not aware of what else may have been done.. Ron.
