Using the lower hole in your pic should gain you some lift height.


Thanks Sam. I will give that a try

I think there should be a bushing in there (Parts Catalog shows something, not clear what.) It also looks like yours has a bushing of some sort already. (Maybe just a wear pattern makes it look that way.) If so, you could look at replacing it with one that is a tighter fit at the inside of the bushing. Moving to the other hole as SamsFarm indicated is what i was trying to suggest earlier.

I went out and moved the lift link to the lower hole - that got an increase of 1” to the blade. Now up to 7”. I found a manual for the fast hitch and it shows that at max lift the top of the pull bar should be 28 1/8” above the floor. Mine is at 22”. So i am missing 6”……. I wonder where it went…. There is definitely a bushing missing at the lift arm attachment to the lift arm, and i will replace, but that’s not worth 6”. Help!

Thanks Jim. I think our posts crossed paths!

I see that the rockshaft rod has been repaired/reinforced at some point in the past. It is possible that the rod length was changed, contributing to your lift height issues.

That is an excellent observation, Don. I have considered that and looked under the angle iron welded on and don’t clearly see where it might have been lengthened. You don’t happen to know what the length overall should be do you?

Unfortunately not. Maybe someone with a 140 Fast Hitch will chime in.

Get a picture of the hitch from far enough back to show the whole hitch. We may see something not mentioned in your descriptions. Also, post a picture of the Touch-Control arm and lift link with the hitch fully raised. I want to see how far forward it moves.

There is a possibility that your left side rockshaft arm on the touch control is twisted.

Like if it was overloaded!

I have a super A and one is twisted on it.

Being twisted would change the index point.

If you push both touch control levers forward and look at the 3 rock shaft arms on the touch control, they should line up evenly.

I cant remember if those rockshaft arms on the touch control are keyed. If keyed, maybe a key sheared at some time in the past

I will check those next time I am out. But you have me thinking about something else. Should the rear lift arms be parallel? Because mine are not. The left side is rotated forward compared to the right and there’s a bunch of weld in a plate there. Like it was overloaded like you said. You can see that in this picture. I also have to have the left adjustment crank quite as far down to level the hitch which would also go along with that. If that’s my problem, it sounds like I’m out of luck unless I could maybe shorten The lift link to compensate…

I think the lift arms on the rear rock shaft should be equal. Pretty sure My cub is!

Since your left is higher than the right then you'll lose lifting height

Not that it will help your lift height, but the lower part of your diagonal brace should be on the front of that pin, not in the back.

I think there is multiple holes on the top side of that right side vertical link that your diagonal brace is attached to.

On the top is a short collar, and below the swivel link is a longer collar.

You might try swapping the collars and then screwing in your left side adjuster link to level the cross bar!

And try inverting the swivel (between the 2 collars) so it sticks up above the lift arm.

Thanks Sam and Jim! You guys really know your stuff! I will give all those ideas a try. It seems like that might actually give me some more live height too. I will report back on the results!

do you have this rod installed?

I got my 140 with the fast which but the bail assembly bolted to the underside of the platform. Installing the rod and using the other TC lever increased my box clearance a great deal
