To all:  This is my first post and need for help as a new member.

 

I have a MF 10 that has been repowered with a new 14 hp Tecumseh.  I am attempting to hook up a MF 650 pto rotary tiller.  I do not have a manual on the tiller and have been trying to hook it up by what pictures I can find on the internet and this site.  I have gone through the auxiliary gearbox and only had to replace the output shaft seal.  But I am not sure what weight gear oil to use in the tine rotary gearbox - 90 or 140, or what?  I am also guessing by using 90 weight in the auxiliary gearbox as well.

 

Besides needing a manual for the MF 650 PTO Rotary Tiller, I would appreciate any information where I can find manuals on the MF 610 Mowing Deck, and the MF 620 Snow Thrower.  Also, do these manuals include parts breakdowns and parts lists and any "service" information?  Please advise.

 

Blessings,

 

Mike

Welcome to GTTAlk. I'll check our manuals section to see what's there. For parts diagrams you can go to Agcopartsbooks.com and log on as a guest. This will allow access to MF parts diagrams as well as any other Agco brands.

Lots of manuals for the 10/12 and their implements. Even service manuals for the tractors.
You will be limited in the downloads until you have a few posts in, so the members will have to help here a little.

My 90* gearboxes had some play in them, so I went from the sludge (old 140 I think) to half 140 and half Grease. They are quieter that way and I feel they are still getting lots of lubrication.

The manual calls for SAE80.

What parts of the installation are you having trouble with? Be glad to help if I can.

Gentlemen,

 

The information you posted was certainly a great help.  The pictures shown in the manuals were certainly worth "more" than a thousand words each.  I have the 38 inch model tiller and after reading the manuals and looking at the photos, I have the complete "system" mounted.  I will pickup a heavy duty "green" Gates belt for the PTO drive tomorrow.

 

However, I may have incurred an additional problem.  I can manually by hand, turn the drive shaft one complete turn in opposite directions before I see any of the tiller tines begin to move.  This seems to me to be "excessive" play or slack in the tiller gearbox.  I would appreciate any knowledgeable feedback as to this being normal, or will I need to adjust the gearbox to a closer tolerance?  If it does need adjusting, I'm assuming that the end plate is how you take out the play- ???   I also plan to drain and replace the tiller gearbox oil before using.

 

Please advise.  I would like to address this situation before trying to till the west 40!

 

Thanks,

 

Mike

I would tend to agree that it's excessive play, is the play all at the input to the tiller or is some of it in the gearbox too?

The tiller has a cap on the back of the gearbox that should have a cotter key holding it, that's the Lash adjuster for the worm drive. Do not over tighten and it may not remove all of what you have for play... Just depends on how much use the last 40 years have given it.

The auxiliary gearbox is in exceptional condition.  All of the play is in the tiller gearbox.  I'm sure it has had an active life with the previous owner or owners, for the tines are worn from 1/2 to 3/4 through.  I'll try adjusting the play out.

 

Thanks,

 

Mike
