MMM Mower Installation Problems (60d autoconnect on 1025r with autoconnect pto)

A few days ago, I reinstalled my 60d autoconnect deck on my 2018 1025r with autoconnect pto, and I am running into a couple issues that I did not experience last year (first year I owned this tractor), and I would appreciate your thoughts on this.


Problem 1.
When trying to install the deck, the tractor pushed the deck instead of driving over the deck.

I used my load and go to place the deck in the same spot on my asphalt driveway that I used last year to install/remove the deck... then I dropped my loader, put the tractor in low gear and 4wd, but after several attempts the tractor would not drive over the deck (tractor just slid/pushed the deck)

Then I repeated this process on 2 other spots on my driveway... same result.

Then I put vinyl car mats under sides and front of deck... same result.

I moved deck to another spot on driveway, did not use car mats, and the tractor finally drove over the deck, and the deck installed ok. This time I had the loader (no bucket) on.

Last year I was able to easily drive on and off the deck without this problem and I did not have the loader on last year. The only differences I can think of between this year and last year is that the driveway was a touch damp (morning dew) and the temp was cooler (65 vs 80+ last year) and this year I had the loader on when the tractor finally drove over the deck.

Any thoughts about why the tractor had difficulty driving over the deck?


Problem 2.
This year the blades were 1” to 1.5“ out of level side to side... low side was discharge side. This was very noticeable in the cut quality. My visual inspection of linkages on both sides did not show any obvious differences, but I gave the deck a shake on both sides but that did not fix the problem. My next attempt to fix this was to disconnect the deck, then reconnect the deck... that improved the blade level but blades are still out of level almost 0.5”. My question is... why were blades Level at the end of last season, but not at the start of this season?


Problem 3.
I can’t drive off the deck... but I figure the solution to “Problem 1” described above will fix this problem as well? Note the driveway was not at all damp when trying to remove the deck.


I would appreciate your thoughts on this.

Yep. The back of the deck and middle section of the deck front was flat on the ground.
Did you remember to unlock the gage wheels before driving over the deck?
TY for responding. Here are some of my thoughts in return:

1. The tires were not spinning on a stationary deck, but they were turning as they pushed the deck forward

2. Tractor was in low and the 4wd selector was on 4wd and the parking brake was off. I don’t really know how to verify 4wd is working other than the turning radius is larger and turning feels a bit “jerky” when on my asphalt driveway, and the tractor felt like it was in 4wd?

3. My engine rpm was NOT up, I had it in idle... maybe that was the problem, but last year idle worked... I’m not saying idle is best though. When I next try to drive over the deck, I will try using higher rpm... I might not try again till early next week. Another thought... when the tractor eventually did drive over the deck, it was in idle and the loader was on, but the deck was in a different/new location on the driveway.
The drive on/off problem. The first thoughts that came to mind are that your 4 wheel drive is not working or not engaged, or your engine RPM is way too low try, 2500 RPM. The second thought is that you were not in low range or your parking brake was on when you tried the drive over. The other problems will require more thinking for me, maybe someone else can answer those.
Edit: As you were attempting the drive over, were your front tires spinning? If they were it was a traction problem due to the wet or muddy tires. Try again with dry conditions.
TY. I considered trying the yard, but my yard has a minor but noticeable slope toward the creek that runs the entire side of our yard. I think I can find a spot that would be level “enough” side to side, but it would not be level front to back... could be 2“-3“ difference front to back... do you think that would work?
Quite often the deck will slide on pavement, concrete, or other hard surfaces. If you have load and go then place the deck on a flat spot of your lawn, make sure you're in 4wd, and make sure the deck wheel are up and unlocked.
TY. Next time I try driving over the deck, I’ll try higher rpm. What rpm do you generally use. I’m not confident that I would hit the deck square with a running start 😳
Sometimes my deck drags too. The first thing I try if/when that happens is put the front tires right up against the deck, throttle up and goose it til the front wheels are solidly planted on the deck ramps.

If that don't work, back up a couple feet and get a running start at it.

Those two solutions always work for me on the occasion that my deck drags. Usually though it doesn't give me ANY trouble.
TY, and I can give that a try.
I've had the best luck connecting/separating it on an incline. It won't slide up a hill very easy.
TY.

I’m not sure I checked pto selector... I will check that. However, once the tractor drove over the deck, the pto hooked up easily and on the first try.

Yep, the height adjustment was set to “install”

When I tried backing off the deck, the deck detached from the tractor, but the front wheels would not drive over the deck... the wheels just push the deck backward
Mine slides sometimes also but not much. Also make sure the pto selector is set to rear only.

I also assume the you have the height knob set all the way down to the install position.

When you say you can’t back off the deck is it coming loose from the tractor and then it just slides? Or is it getting hing up on the tractor and not coming loose?
TY. I don’t know what that is but will look that up.
You could probably put some grip tape where the front tires initially contact the deck to help them get traction.

TY. That does seem like it would be a help.
I've never had it go as easy as the demo videos show when installing my 72" MMM on my 2038 but I found that placing a couple of 2"X6" wood planks on the ground next to the deck to help my front wheels climb onto the deck easier. Dismounting seems to go better for me put you can do the same if again, your wheels struggle to climb up on the deck for removal. Good luck.
Do you rev up the engine when driving over the deck. TY

The fix that got my tractor to climb over the deck was simply to rev up the rpm’s a bit... I moved up to 2500 rpm and the deck climbs the deck without hesitation or difficulty. I’m not sure what the minimum rpm is required, but 2500 worked great. Thanks to everyone that gave suggestions!

Now... do you have any ideas why the deck was level side to side, at the end of last season, but is not level side to side at the start of this season (deck is at least 0.5” out of level)?
LOL... I don’t like the sound of that. I mowed all summer last year and did not notice a leveling problem... but the leveling problem was immediately noticeable this year.
I had a 2013 1026r.. same issue I never could mow more than 3 times without readjusting the deck. The dealer replaced about anything to do with the lifting of the mower. Never would stay adjusted, apx 3 yrs later and some of issues with the tractor, traded in tractor and mmm , bought a 1025 and 54" deck. I might adjust the deck every couple of years , that was 2015

You will never forget that tractor!
What did you replace it with?
Where do you set the gauge wheels when you mow?

I‘m guess I need to lower the gauge wheels on my deck as I get scalped spots out at the edges of the deck even when I hit a minor bump in the yard.
I didn't like it either, IMO the shaft for the gauge wheels need to be another 2-3" longer . That way the mower would be either touching the ground,,,I know they are suppose to be 1/4-3/8" off a hard surface.
The main reason for me trading was, dealer had replaced the mid pto seal 3 or 4 times and would continue to leak, plus the main straw that broke the camels back . The tractor had drifted away and went through the side of my building. I had had enough ,

Nope... I never move it with the draft link... and I figured out what the problem was and will post that n a few minutes. TY for your thoughts and pics,
When you had the MMM off did you happen to move it around by picking it up by the draft link? It is easy to pop the draft link out from between the deck hook and the pin indicated by the red arrow below. If the draft link is not trapped between the hook and pin things will be all out of alignment both for connecting and for the mower level. It is a small thing easy to overlook so check both sides just to be sure. It is pretty easy to fix if this does turn out to be the problem.

I believe I figured out the problems and solutions:

Problems:

a) Tire pressure was low in all tires and unequal side to side and front to back. Not sure why, but maybe that happened over the winter?

b) I did not have pto in “rear only” when I first connected the deck this season

c) I was in idle when I was first trying to connect/disconnect the deck this season

Solution:
I took the deck off a bit ago then I inflated tires to proper psi, and put pto into “rear only”, and I increased engine speed to 2500 rpm... as a result, I had no problem driving/climbing over deck and the deck is level side to side within 0.25”.

Although I’m not 100% sure how much each of these things contributed to the problems I experienced, I believe all 3 contributed to the problems... but maybe improper tire pressure was the largest contributor?

All rookie mistakes!... and I am a rookie.

TY to everyone that took time to share your thoughts and suggestions.

This morning I needed to remove the deck to do some loader work, and again, conditions were wet and I had problem backing off deck, even with rpm up to 2500 and more. I recalled your post and used couple short 2x4’s as “steps” and the tractor got over the deck with no problem! Looks like when conditions are wet, I may need to use both higher (2500) rpm, AND the 2x4 step? Thanks for posting your suggestion!
On the deck sliding issue: I have an X754, 2-wheel drive, when driving up on the deck, I drive forward, which you are not supposed to do with 2WD. I'm on level asphalt. I take a 2x6 and a 2x4 and make a mini ramp for the front wheels. It is just enough to easily get the wheels on the deck without the deck moving. Give it a try, works great.
