Broken Lift cylinder?

I am running a 50C deck on mine. At the max lift height and the deck level my blade is only about 3 inches from the concrete. I am able to put about a fingers width under the front anti-scalping wheels (set in the bottom holes/highest cutting height setting) when the machine is on the concrete. Not a huge deal but nearly impossible to clear major obstacles and forget about loading it on a trailer using a ramp with the deck on.

That wasn't too bad...maybe I'll make one tomorrow and see if it works.

You kids and your 3D drafting and modeling software....

New cylinder is in thanks to Matt's help with an Epay find. 55 bucks with shipping. Now just have to get the lift spacer in. One question, it looks like the mower lift is connected to the same shaft as the arm that connects to the cylinder. There are 2 roll pins that go thru the shaft. Do those pins need to come out for the mower arm to move independently or "float".

[Matt G.]

Nope, it should already float on the shaft. Sounds like something is rusted stuck, or the float lockout bolt is installed.

[Matt G.]

The lift bar has a slot where it connects to the 3-point rockshaft, so it has its own float that's independent of the deck float. The 3-point lift arm connects more or less directly to the hydraulic cylinder, so it has nothing to do with the deck float.

[Matt G.]

I guess I walked into a trap here...you said it's "probably set up for down pressure on the hitch" and then in the same breath "float your deck and lose the pressure at the hitch", and now you're saying that the 3-point NEVER floats

Still, the rockshaft float is still independent of the 3-point. The 3-point bar connects with the same clevis pin that holds the cylinder to the rockshaft. The rest of the rockshaft rotates inside of that part, and the 3-point will work the same, regardless of whether or not the float lockout bolt is installed.

You may have to change the way it's connected to get the deck to float.

I guess I am getting a little confused in the discussions here, but in the picture here, my 3 point bar is connected with a bolt from the right side thru the bracket with a hole for the pin that connects the cylinder. Essentially the mower lift arm is not tied in to anything. My question was specific to the 2 roll pins that are pictured here. Looks like some PB blaster is in my future...

Those two roll pins need to stay put. The rockshaft/lift needs to move freely of the clevis piece that the cylinder connects to. It may be froze up and keeping your lift arms from floating.
