i have a 2011 m135x and it has enough power on flat ground with the baler. but as soon as there is a bit of a hill its gutless i have contacted the dealer a few times and there is nothing they can do. is anybody else having this trouble? i hear there is a chip available for it has anyone tested one out yet? i am pulling a case rb564 baler. i run this beside my dad who has a jd with the same hp and he has a jd baler we make the same size of bales they are large but not extreme 1800 lbs. when there is a hill he can gear up if he wants and i have to go from h4 to h1 and even then its powering down to 1500 rpm. i try to keep it about 1000 pto rpm i have tried using the engine cruise and it doesnt help..... i have taken off the loader, changed air filters and fuel filters.like the tractor but cant have a tractor with no hp need some info on these chips or maybe i got a tractor that has no power. also my loader drops with tractor off and even with tractor running i notice my 3 point will drop down a few inches sometimes for no reason when i am outside working on something???? anybody got any experiences like this?????
