I've got a question for you guys. I have a case 770 that is having issues with trying to lift up a newer disc mower. I ran for four years A New Holland 452 disc Mower and the lift cylinder operates without any issues. I recently picked up a Vicon cm2400 and I have had issues with the lift cylinder picking up the actual mower into transport position. I've already checked to make sure that the pressure relief valve is working properly, and the gauge has been reading 1400 to 1500 PSI (which is what the tractor is rated at).Does anybody have any thoughts on how to alleviate this problem or any tips that I am currently overlooking? I've called the local case dealer and they do not offer a higher PSI rated pressure relief valve. Any help would be great thanks.
