I got stress cracks in the factory massey loader. Numerous front axle issues. Dealer finally admitted the are having issues with front end on tractors with heavy loader usage. Now according to you the relief valve should prevent me from lift anything that should damage the loader or the tractor. Well I can basically throw that idea out the window. When you got a bucket of dirt up on the loader and you go to turn the wheels and the steering cylinder breaks something has a design flaw because according to you with the relief valve should prevent prevent you from picking up too much. You digging and you are using 4 wheel drive for added stability and traction. You got a bucket full of dirt and you try to back up. Pop, there goes the front axle. With the relief valve, you shouldn't be able to lift enough to cause a problem. If I own a 30 hp 4 wheel drive tractor with a factory loader and five bucket and can't dig a hole with it, then it is not much of a tractor. Guys that really use their tractors have had problems. I 've seen it, a guy have a loader rated at say 2100 lbs and he's feeding a bunch of cattle and setting 3-4 big round bales per day. The continual weight, stress and flex of that type usage and next thing you front trouble and or loader trouble. He never over loaded his loader. The Brute strength you need just isn't there despite what some salesman at the dealership tells you. My guess is that probably 50% of the people never really work their tractors heavy. That is why I contend that in town or a little 10 acre plot my mf 1531 would probably be ok. And why do you suppose out here in the heart of ag country you are seeing much of anything but mostly John Deere and case-ih??? Are we just a Bunch of hay seeds that don't know nothing about tractors???
