Hi,I recently obtained an M, with an F-10 loader on it. The loader hydraulics are powered by a pump which is driven by the PTO. I"m interested in getting a mower to drag along behind the M (with the loader off), and began to investigate the built in hydraulic system (the operators manual calls it a "lift all", the repair manual seems to be temporarily misplaced). On the left side of the tractor, I have the two elbows coming out, and there is about a foot or two of rigid line/pipe on each with a coupler (looks like a hydraulic line would attach). The single right hand port is capped off. The lever that looks like it would be used to engage this system looks slightly different than the one in the manual, in that it has two holes (for a clevis pin to attach) instead of one. Where the manual shows a breather cap with a removable plug or nipple, mine is just a solid cap. The manual seems to say that there is a dipstick of sorts built into this cap, but I have none. If I pull the lever back and hook it on the second notch, I can (after cleaning the grease and dirt out of the coupler) push in on the ball in the center of either of the left hand side (LHS) couplers. No hydraulic pressure. I have not tried having someone else hold this lever all the way back, just resting it on the stop. I can"t hear any change in the sound with it engaged or disengaged. So, how can I figure out if it"s working and fix it if it"s not? First, It probably needs fluid, but not too much. There seems to be a plug partway up (or partway down from the fill), as one would use to check the level (and fill) a manual transmission. Of course, there are several of these all over the tractor, so I"m not sure which one goes w/ which reservoir. The book says use 30 wt oil? Given our more modern options, would some sort of hydaulic fluid be better? Is this the right way to start? Don"t be afraid to point out the obvious (you won"t hurt my feelings). I"m not sure exactly how the system is supposed to work when it"s working. Note that although I"m (very) new to tractors, but I do know my way around cars and motorcycles when it comes to turning the wrenches (albeit much smaller wrenches, I"m gonna need all new tools!). Thanks in advance, Bob 4knee
