MF 175 Mystery Lever and 3 pt control question

First up the mystery lever.. When facing forward there is a lever on the right hand side of the transmission housing that appears to be marked "ground" "neutral" and "engine". What does this lever do?

Second, the hitch control..
This lever has several settings, up down etc. There has been a stop bolted in that prevents it from being moved beyond "transport" over to constant pump and the high - low pressure range. Will removing this stop and moving the lever into the high pressure range improve the lift pump performance?

Any advice is very welcome.

Thanks! c0

One thing that I am curious about though. How do you purge all water out of the hydraulic system? I changed out all of the fluid, only to have it go white again (although not as white as the initial fluid that I drained).

Thanks Again!!

The lift on my 135 was crap as well. I put in John Deeres "hi-gard" and it now works perfectly. Be warned, its expensive!

"ground" is where the PTO will turn in direct proportion to the speed at which the trator is travelling. You dont need to know about that - its not used much. Engine is the one you want to use for nearly all PTO implements. The PTO turns at the speed that the engine is running.

the levers on your right. The far one is draft control, use it when your plowing, the rest of the time keep it all the way up in high position.

The left lever has Position control which is used when you want an implement to hold steady, ie with a back blade. Thats the bit towards the back. The bit towards the front is for remote hydraulics. If you want to use these, ie for a tipping trailer, undo the "stop" thing, and put it right down the bottom. Now push the left hand lever right down to the bottom, now you can connect your hose. When you actually want to tip or whatever your using it for, pull the lever up, but dont go into the position control section. (ie only go half way up). To hold the trailer up you can go about half way. (ie a quarter of the whole distance)

If you have any more wuestions post them here, or email me, [email protected]

The Hi-Lo pressure ranges on the quadrant are for use with a pressure control hitch. I don"t know of anyone who uses one or has ever used one. It was a feature which never took off which involved chaining the drawbar of a trailed implement/trailer to the device, so that when traction was lost the drawbar would be pulled up, transfering weight onto the rear wheels of the tractor from the implement. More often it bent the drawbar on the implement I am told... So in answer to your question no it will not improve lift performance. If it is poor first port of call is the o-rings on the pump to head stack pipe. Sitting in the seat, on your right hand side, on top of the lift head (what the seat is bolted to) you will see either a plate or a selector valve secured by two bolts. Remove this and the stack pipe sticking up. Replace the o-rings and reassemble, being careful to get the pipe back into the hole in the pump. Next try the strainer which is a bit more involved. Recommend buying a workshop manual if you need to do this so you can see the layout inside.
