How Can I Get Mower-Deck-Height Adjustment Lever Unstuck?

Recommended Posts

Hi all:  I have on old but serviceable 310-8 with a 10 horse Koehler.  

 

I put the mower deck into the lower position yesterday for a small part of the yard to create a sculpted effect.  To do this, I pressed the button on the top of the lever on the left side of the mower and let it go forward.  I have done this many times before without any problem.  I can always pull the lever back up and raise the deck to the higher position I need for most of the yard.

 

However, this time the lever to raise & lower the mower deck decided to lock up.  It won't move out of the lower position so I can now only mow in the lower position, which is not good for most of my yard.  I can push on the button on the top of the lever and pull the lever up a bit, but it won't raise the mower deck.  Just won't budge.

 

I disassembled a couple of pieces of sheet metal to get a look into the insides.  (I removed the left foot support, the  vertical panel above it, and the "control panel" that houses the ignition switch, gauges, etc.)

 

The linkage underneath seems fine.  

 

So, the source of the problem appears to be with the mechanism connected to the button on the top of the lever and/or its associated parts internal to the lever.

 

My request for help is:  What do I take apart next to get at this mechanism?  

 

The level is mounted on a vertical plate on the left side and appears to be a single piece.  That is, I think I can take off the lever assembly but I can't see anyway to get inside it.

 

Any assistance or advice on how to proceed will be greatly appreciated.

 

Thanks.

If you have twisted the black knob that regulates the tilling depth etc. to the lowest position, then the deck lever will not lift the deck. Make sure that knob is twisted all the way counterclockwise to allow the lever to operate.. To normally regulate the mowing depth you use the slotted lever on the mower deck itself.....:twocents-02cents:

I had something like this happen on my son's tractor.  I took the deck off and tried lifting it manually.  As I recall, one of the leveling adjustment mechanisms was binding on something.  When it happened, I could not use the slotted adjusting lever on the mower deck.  I'm testing my memory here, and that is not always a good thing.  All I know is I had to take the deck off to get to the bottom of the problem.  I hope this helps.

Hi again:  I tried twisting the top of the large lever on the left side of the machine, but it didn't move.  I don't think it is adjustable.  

 

I used a largest pipe wrench I have, but it simply twisted the plastic handle on the end.  There doesn't  appear to be an adjustable knob underneath it. 


If anyone has any other thoughts, I'd surely appreciate hearing them.

 

I think the next step is to see if the deck mechanism is binding somehow underneath the machine, just above the deck.

 

Thanks.

OK...I fixed it, but oddly, it seemed to simply be accumulated grass clippings that were gumming up the works.  I had taken it apart as far as I could and was about to give up when I noticed the old grass clippings.  A few minutes with the air compressor hose did the trick.  Go figure....

Sometimes it's the simple things. Glad you got it fixed and shared the answer.

Grass clippings... :angry-banghead:

 

I keep finding more every time I go a little deeper into my 520H. The only place I haven't found them is in the engine cooling fins, thankfully. But I keep finding old clippings packed into every little crevice they can get into. I keep blasting them out with compressed air and the hose... I figure one of these days I'll get the previous owner's lawn out of my tractor! They haven't messed up anything mechanical yet, but I keep trying to drive them out before they do.

Here's the worst one I've run into the 236hr '95 I got last spring, Jeff.

Yeah, that's pretty typical of what I keep finding... I think I'm running out of crevices and blind spots that they're hiding in now, so it's getting easier to blow it out and keep it clean after mowing. Believe it or not though, I found more than what's in your picture packed in under the fender pan and more mud, clippings and spilled oil all mixed together on top of the transaxle. I can forgive the previous owner, but the problem was the shop that did the routine service. They'd fix what was broken or do whatever fluid changes it was brought in for, and not one thing more -- including cleaning things out to inspect it better.

 

Would you believe -- I opened up the steering tower to do more cleaning and checking, and found the little pull-back spring for PTO lever completely disconnected... and sitting in clump of clippings! :o It had been that way all along from before when I bought the tractor, stayed there through the trailer ride home, multiple mowings, and even when I'd sprayed water and blasted the area with air!

It's not a bad idea to expose those areas and clean it with a pressure washer or some flavor of degreaser - that will help keep the dirt/grass from accumulating so badly . I immediately fix oil/grease leaks on my equipment and everything gets a 110psi blasting of air after every mowing . The cleaner you keep this stuff , the longer it will last...

I guess I'm not looking as much since I bought the Mahindra eMax just don't need anyone for now lol, I have had the anniversary 520H since new in 1998 and it won't go anywhere, then went on a :wh: buying spree last year 2 more 520Hs 1 with a bagger and the 523Dxi that the engine was shot in with 48" snow plow and lastly a 520xi with 60" deck then a 42" single stage snow thrower for it, after finding the engine ruined in the Dxi I went on a selling spree to help offset the SCUT purchase, Jeff.

Sounds fair enough if it runs and drives those tillers work great on previously worked plots not so much on virgin sod ,Jeff.
