Yesterday just at dark I jumped on my D-14 NF mowing tractor to move it back to the shed and when I pushed the clutch pedal down prior to turning the key it felt weak..... a second push confirmed no resistance. Linkage outside the torque tube is good, spring not broken and rod working with the pedal.

Today I am going to see if the rod somehow let go from the release bearing fork or worse. If I recall correctly doesn't the linkage rod screw into the fork for the release bearing... sure feels like the rod has zero resistance but I guess the fork could be pivoting perhaps without any resistance if the release bearing gave up or separated somehow. I recall the pivot for the fork MAY have a cotter pin somewhere? Too many different color tractors and I may have it confused.

Got it started in gear with low throttle and SLOWLY made it to the shed. Later this afternoon or this evening I should be able to get a look. Any experience with a D-14 doing the same thing?

I would guess the throw out bearing went out and cut fingers off pressure plate. MACK

I had a similar thing happen to my D17IV except I was moving when it happened. I was pulling into my parking spot and pushed the pedal only to have it go all of the way down. In my case, the pivot block that the clutch rod screws into had slipped out of the release lever. There is a bolt and a nut that puts tension on the "ears" of that pivot block and the nut backed off allowing the block to pop out. I did the repair through the inspection hole on the bottom of the housing.

I am hoping for a similar outcome and the ability to work in the inspection hole. If not, a new clutch might as well..... Rain kept me from getting after it this evening. Thanks for the responses.

Before you put it all back together...be SURE the release arm is on the TRANNY side of a big casting 'nub' and NOT on the ENGINE side !!!
I'm thinking the 'nub' is to keep arm/rod form going too far in ?
Yeah, I found out the hard way....only took 2 of us another 30 minutes to resplit, put it in the correct location, and 'tighten' things back up .

yep, that casting nub is a stop.

Guess what happens if you push too far past that nub on a B?

that's right, over center and now you got no clutch!

Nearly killed myself with that one.

If by chance we have the same issue, the above is the link where I reported the fix, findings and frustrations. I hope it can help someone!

Mack, you were close..... the throw out bearing froze up and while it did not take out the levers from the clutch assembly all the way, it ate them up a bit until they no longer had enough metal left to contact the bearing resulting in no contact.

Funny thing is the clutch disc is like new. I have owned and mowed with this tractor for 3 years. My guess is either the bearing was not replaced or it was a Asia junk piece. It seized bad enough to actually spin the cast sleeve on the fork 90 degrees. Only the fact the fork was indexed between the casting nubs kept it situated properly.

NV4500..that link did not take me anywhere. Might be me but it would not open.

Time to get Rick in MO. working again!

After your new stuff is in ,check free play on bearing every once in while . Clutch needed adjusted and spun the release bearing all the time .That will burn the grease out of them.
