MF135 Multi-Power Hard to Shift

I have a 1967 MF135 diesel with multipower. It was purchased new by my great uncle. When I am using the multipower in high range I find that it is very difficult to shift between gears. Sometimes I question if I will ever get it out of gear, while other times it seems to work fine. When I am in the low range of multipower I can shift through the gears with no problem. The transmission oil looks like new and it is always stored in the barn.
Any idea as to what the problem may be? It seems like getting it to go from reverse to neutral is the most challenging.
Thanks.
 
If you experiment a little, you will find that if the tractor is pointed downhill, it will come out of any forward gear in high M-P with ease. If it is pointed uphill in a forward gear and high M-P, it will lock up when you push the clutch. That is the "hill holding" feature. Be thankful your M-P is working.
 
Thank you for the replies. The linkage needs to be adjusted because when I have it in MP high, you cannot put it back in MP low unless you get off the tractor and lift the plunger by hand. Looks like an easy fix, just been too lazy to actually do it.

My father told me that his uncle would never use the MP but he wasn't sure why, we just assumed it did not work. I mow a five acre field with the tractor and using MP high reduces my mow time by about 30 minutes. Low range third, MP high gives me a ground speed of 4mph. MP low is closer to 3MPH.
 
On my brothers 150 with multipower I never noticed any difference on how it shifted when it was in either high, or low range multipower. I don't know if my brother didn't either because I've seen him change gears with the multipower in either range. We never changed gears while on a hill, only while on flat ground.
 
Yes sir, helps to know which driveline tractor is equipped with. Most US models have the dual clutch, but very late tractors could have the IPTO option. At least where you are there are very few gas, or what you call petrol models to deal with. Dang spark plug engines anyway! REAL engines are Diesels!
