Hi, thanks to y.o u guys, I have ordered the owners manual for my 420w. Now, two more questions. I don't believe my three point hitch arms are lifting as high as they should. Is there a way to adjust them so they lift higher? I still have not found out why there are two levers side by side on the right side where the three point lift lever is. ONe of them doesn't seem to do anything. Could that be the reason it does not lift as high as it should.? I am learning but when you are old it takes awhile. PS It is full of hydraulic oil. thank you all very much for the help.
