Just had the 1023e delivered yesterday and we were going over everything on the tractor. Tried to disconnect the mower, but the latch was too tight. Eventually it came off, but it had a hard time trying to get it to connect again. I jumped off the tractor to take a look underneath and for some reason, the connection isn't lined up. The dealer rep didn't know why and will send a tech out to diagnose, but has anyone experienced this before? See pic....

Unfortunately sounds like a bad setup to me. The mowers are a dealer installed option.

Your auto connect pto is not adjusted properly. Looking at he picture the two components need to line up so the male shaft slides into the female auto connect pto. The good news is it takes merely an adjustment to correct the issue. The bad news is when set up like yours is there is a bind even if you can get it to hook up. This is the worst possible way it can be set up and should not be used, set up like this.

The auto connect pto carrier (on the tractor) can move up, but cannot move down. In your situation the weight of the mower deck will bind and will eventually cause something to break. It is much better to have the auto connect slightly lower(1/8" max) than the gear box spline on the mower deck. Yours is set up so the auto connect pto is higher than the gear box spline on the mower deck. Also the carrier bearing on the Auto connect should be set up parallel with the Gear box splined shaft on the mower deck. Yours is not.

Once set up properly it will connect like a knife through hot butter. Do not use or connect the mower deck set up the way it is. You could easily break something. If you are capable of adjusting it do so, if not get the dealer to set it up for you.

Did you have the (rockshaft?) lever all the way up? It's the big lever on the right of the seat- pulled all the way back is up?

The mower adjustment height knob was all the way counterclockwise to the "install" position?

Pick a mower deck height point- I use H most of the time.

And then you lowered the rockshaft lever all the way down?

Copy that^^
If you're like me and paid an arm and a leg to have the MMM installed, I'd be rather adamant about a personal visit from an experienced tech to get this corrected.

My opnion is that some Deere higher up marketing person wanted this MMM. Deere engineering was required to design it over a weekend, so they turned it over to the new guy with a brand new degree in mechanical engineering from Georgia Tech who unfortunately had never been around tractors before. (I use Ga Tech in my opinion since I have brothers-in-law with engineering degrees from there).

My advice is to spend some time reading through the "sticky" on the MMM adjustments at the top of this forum.

It will take a while to get your mower set up correctly so that it reliably mounts and dismounts. I've been at the adjusting game for going on three years with mine and it's still not perfect, and likely never will be. Don't hold out in the hope that the dealer will eventually sort it all out. Slide under there and start tweaking things yourself.

The long threaded bolt that attached to the bottom of the driveshaft coupler/carrier bearing is not adjusted correctly. To adjust:

1. Mower deck removed from the tractor and parked on a LEVEL surface.

2. Height adjustment set to "Install" position, so carrier arm is fully down.

3. Place a torpedo level across the face of the coupler/carrier bearing and adjust long thread bolt for plumb (aka: vertical level).

Sadly, if they didn't adjust this correctly, the rest of the deck setup is probably not correct either, as this is the easy part.

Your deck latch is tight because your front draft rods are too tight. With the deck on the ground there should be a small gap between the hanger and the rod. Hopefully the tech that comes out adjusts everything correctly. Better have them check that the deck is level while they are there.

As best I can tell from the picture, there is no grease on the mating parts. Obviously, they are also out of adjustment. But I always use a brush to apply grease to both the mating parts. Everything goes smoother with grease, and it also helps to protect the parts from wear.

Also, there are two setscrews that secure the male coupler to the mower deck gear box input shaft. They like to work loose and when they do, they will cause the coupler to jam together. Remove the setscrews one at a time and apply blue Loctite to the threads to prevent them from working loose. I check mine for tightness as a part of my end of season mower deck maintenance, also.

The Service Tech stopped by yesterday and adjusted a nut and the entire unit shifted down with each turn. 5 min fix. Thx for everyones input!

It'll sure be great if that resolves it, the truth well be in the quality of the cut.
