1811 Mower Lift

[lakebilly]

I've got a situation where the 46" mower deck will not lift to the fully retract position. In fact it only comes up about 1/2" from the mowing position.

I can manually lift the deck to the full up position and everything seems to be fine from that standpoint. Nothing interferes with it and the linkages all look good.

Does anyone know how much stroke the hydraulic cylinder should have? It seems to be stroking about 2". If it could go another 2" I think the deck would lift to the full up position.

Thanks in advance.

Pop the cover off. See if the cylinder is moving full stroke.

Cub decks never moved much, compared to the "off brands".

Thanks for the reply and thanks for moving my post to the correct forum. I'll watch that in the future.


The cylinder appears to be moving full stroke. I would say about 2 1/4" from the fully retract to the extend position.


What I'm seeing is that the lift bracket doesn't contact the rockshaft until the cylinder has stroked about 1 1/2". At that point there isn't much stroke left to lift the deck.


When I get home from work tonight I'll post a few pictures.

I love this forum!!

That's because the deck is probably sitting on the ground when the lift is all the way down, and the cylinder extends further without the deck moving once it is on the ground because of the float feature in the rockshaft.

Years ago someone made this little piece to put into the rockshaft to get an extra inch or so of lift, and I made one for my 782D, but due to my frame and rockshaft being messed up from the factory, I couldn't install it. Somewhere I think I have a picture of it and how it installs...I'll look for the pictures when I get home from work tonight.

Thanks again. I'd like to see the part or at least get an idea of how to make one.

Better yet, I found the webpage where the idea came from. Somewhere I have a dimensioned drawing of it on my computer, I just haven't found it yet.

When you try it out for the first time, ensure that the hydraulic cylinder reaches the end of its stroke before the rockshaft hits the frame, or you'll bend the frame. If it lifts too far, the long, sloped side of the piece may need to be ground down more so it won't lift as far.

Matt, I appreciate this. What a simple solution. I've got a machine shop available where I work, so this will be a piece of cake.

Thanks for everything.

Have had the same problem here with 1811 & 46GT deck. CC dealer told me my 46GT deck is taller than most decks and was not intended for use on the 1811 (was probably swapped out at some point by PO), but I've used it for about 12 years that way. Anxious to put that mod. in place and see if helps? Thanks
