Hi, we have a late M with a belly pump, two way hydraulics, hand clutch, and a 115 side-mount mower.When the tractor gets warm it will barely lift the mower so I drained all 2 quarts of quiklift and put in non detergent 40W hopeing that will help.I have read and heard some conflicting info. With the two-way hydraulics I can close the breather right??, it spits out oil like crazy at times and has always been open.the shop manual I found says 6 qts, but does it all drain out when you change it? I also can"t read that 3-piece dipstick to save my life. I put in 4 qts of 40w and tried to read it but as you feed it down the pipe it gets covered in oil from the insides of the pipe. I will try again hoping that it all has dribbled out of the pipe. Can I trust to just put in 6 qts if I can"t read the dipstick? Thanks
