M5640 Lower Link - Actual vs Messick's Diagram Picture ???

[Gordon Gould]

I bought a used M5640SUD Utility Tractor a couple years ago. I wish it had more adjustability in the 3ph. The previous owner told me he had the lower links switched over to the extension type for easier implement hook-up which was a Kubota change at Serial # 60,000. When I look at what is on the tractor compared to the Messicks diagrams there is a difference. Messicks shows for < S/N 60,000 3 holes in the lift rod and two holes in the lower link. I have only 2 holes in the lift rod and only one hole in the lower link.



If I look at the newer lower link it also has 2 holes.



So my question is - are Missick Diagrams generic illustrations or do they depict the actual part ??? And if they depict the actual part is there any way I can get dimensioned drawings so that I can compare to what I have and maybe modify it or get new parts ?? Thanks.

EDIT: FWIW my owners manual also shows 3 holes and 2 holes.

Well I got one question answered. Messicks parts diagram is correct as you would expect. I found a picture on TractoHouse.com of a M5640 that clearly showed the 3ph and it had 2 holes in the lower link and 3 in the lift rod. Now if I could only find someone who has one of those maybe I could figure out what I have and how much the dimensions are different.

Gordon, are you wanting to lift higher? Low 3pt implement lift height is a common problem with the under 85HP M series tractors.

 

[Gordon Gould]

Yes. The few times I have had a problem it was lack of height. This last time I remembered the previous owner said that he had had it switched over so I looked at the Messicks diagrams to see what was original. Don't know why mine are so limited in adjustment. I might just put another set of holes closer to the tractor in the lower links and/or get a second adjustable side link. A nice Fit-Rite hydraulic side link like I have on my L3010 would make it even better and that has been on my mind.

Have you checked to be sure the feedback rod is adjusted for maximum 3 pt rockshaft height?

Thats a great suggestion. I adjusted my m8540 and got 1.5-2" of extra height out of it in the height position. I usually have it in the heavy lift hole for hauling my 5th wheel around which sits at about 4000lbs of pin load

Thanks for the suggestion but yes - when fully raised there is very little travel left before it hits the stops.

Just like what's in the picture. Something to keep in mind, I'm running about 20 weeks out for lead times. Either run them so that both the manual & hydraulic links are typically fully collapsed or splurge and get 2 hydraulic side links so that you have both left & right side tilt at your finger tips.

Or, just use a Hydraulic top link retracted to raise the tail end of the implement when needed. (most common solution)

Just something else to think about for an alternative. :thumbsup:

Hmmmm........... I already have the top link - came with the tractor. Biggest immediate obstacle is only one remote but 20 weeks would give me enough time to take care of that I would think.

To overcome the lack of lift height of my M7060, I added to the bottom of my quick hitch for another set of holes. I believe they are 6" below the original. Works good on the 3-point
blade which would otherwise barley get off the ground in a level operation position.
