74 MF-65 Hydraulics

[gshunt3]

Greetings, I have been rebuilding a 1974 MF-65 which has a bucket on the front. According to the service manual this bucket is considered "External" to the hydraulic system. I have read the info on "Operating External Hydraulic Equipment" and I'm a little confused. Are both External hyd.. control sticks to be pulled back fully to allow for continuous flow of oil for the external controls to get oil?
Second, is the draft control to be "raised" to the Maximum position? Is the draft control lever the one on the Hydraulic Control Quadrant on the right side of the tractor seat, with a "knob" on the top of it? Any guidance would be appreciated. Thanks

The MF 65 was built 1958 to 1964, so I think either you are off on the year or tractor model.

To be entirely clear, is your loader being supplied by the internal hydraulic pump or does it have a pump mounted under the radiator driven off the front of the crankshaft?

Please provide pictures of the tractor, loader, loader plumbing, and all valves (and valve handles) for getting the best answers.

The MF 65 Is NOT a 1974 model. If you mean the two lever valve on TOP of the lift cover, the left one is locked BACK for three point ONLY use, and CENTERED for the right one to then work. BUT the lift arms need tied DOWN, OR draft fully UP to turn the internal pump linkage back ON as when the arms raise with the position control the internal linkage turns the pump OFF. The DRAFT lever fully up over rides that linkage.

I will add that a 65 will have a rounded hood, a 165 will have a squared off hood.

If you look at his posts he has replied to them when he asked a question, so I think we will hear from him soon. His avatar shows he was around less than an hour ago, maybe he is gathering info for us to use to help him.

Your correct, it's a 64, not a 74 (My Bad!) It's being supplied by the internal pump. I finally did get it to work. Thanks.

Thanks for the reply. That should have said 1964. I did get it to work, but now I have a good explanation

Hi to all. I only post when I need help, sometimes it will be sometime before I post again. When I do post, I continue to try to remedy my problem during the wait for a response., and yes, I do manage to answer my own question sometimes. I've been working on equipment for over 60 years and I am still learning. Sorry if this bothers some of you.

It's all good gshunt3. Never mind the chatter. I've been reading and enjoying and learning from these posts for 18 years now. I'm so thankful for the contributors. kevin110

No offense intended to you or others who do as you do, I didn't read your posting history.

It's a common occurrence here for some to post questions then disappear for long periods of time, maybe forever, without any further info or resolutions of the problem, etc.

Good to see you're not one of them.

And a reminder to all the, "Position Control" lever must be in the "Constant Pumping" position to use the internal pump to control remote hydraulics. If you look closely on lever bracket the words are actually engraved into the bracket. Ok stamped.

That's only on the later 100 series if I recall, not on the 35/50/65 older models.
