Hey all! New here!

I decided to join the forum in hopes that I could get a little help with my mower issue.

I recently bought a used 8 speed Huskee, 21HP, with 46" deck. This thing is a MONSTER that likes to chew through everything!

Lately, I have started to notice that the mower will not go over any type of hill, nor will it get going unless someone gives you a little push.

I also hear what sounds like metal rubbing. I am thinking maybe the gears are stripped?

I tried the trick where, with the engine off, I would put the mower in gear and test the tension on the belt, but it doesn't seem to tighten (I can still pull on it with some effort). It is not loose, but it also seems that there is no difference in tension as I go through the gears.

What could possibly be causing this? Is there something I should check/replace?

The drive belt is brand new.

I am hoping to avoid getting into the transmission.

Thank you in advance!

Welcome to the forum ARMYtango!

...I also hear what sounds like metal rubbing. I am thinking maybe the gears are stripped?....

First thought would be a sheared key on one of the wheels where they attach to the axle.

What's your model number?

Hmmm....I am at work right now, but I will have to look for it and get back to you.
I should have figured that would be important...lol

Thank you for the reply!

Ok...here we go....

Model# 13AT688H131
Serial# 1A153B80176

Also, I took a pic of an area I was not too sure what it was.

In the pic, I am not sure what the wheel in the background is and I have not seen it move.

Also, the lever that the spring is attached to barely moves...maybe about 1/4" max....is this all normal, or could this be a part of my issue?

Any help would be tremendous help!

Thanks again!

The wheel in your picture is the brake disc. The shiny spot is where the pads clamp on to it and rub when you apply the brake. The disc should turn whenever the wheels move. The lever would be what operates the brake pads.

You can find online manuals for hit here:

You can also look up parts and exploded views here:

I would venture to guess that if you can pin down the exact location of the metal scraping sound you'll find your problem. Another possibility would be #25 pulley in the diagram below slipping on the drive shaft of the transmission.

 

[ARMYtango]

Ok....well. I guess what is in the picture is ok.

I will check to see if that pulley is slipping, if not, I will have to open up the transmission...

Wish me luck! lol

I will update as to what I find.

Thank you for the blow up and the info! I greatly appreciate it! :cool

Ok, to better show my issue, please click on the link below. I made a short video of my issue/question that I am hoping can be answered before I get into the complexities of the transmission.

Thank you again!

Speed difference from the input to the axle is probably fine. Top pulley will be running only a little less then engine rpm. The intermittent drag could be a clue as to something going on inside or might just be the brake dragging some on the disk.

What it all boils down to is if you can lock both axles from turning and still rotate the top pulley with some effort while in gear, you have a problem inside the case.

Hmmm....great way to put it.

Thank you so much. I will try that out.
If, for some reason, I have the axles locked down, and the pulley DOESN'T move, what other things should I look for?

I do greatly appreciate all your help! :howdy:

Then your back to a belt slipping, wheel rim slipping on axle, or drive pulley slipping on engine shaft. At least those are what i can think of off hand.

The culprit will always be the last thing you check.

The culprit will always be the last thing you check.

Ain't that the truth? lol

Ok....here is my next video:

Huskee Transmission - YouTube

I looked in the trans to see if there was anything that may have looked out of place, or broken, but didn't find anything except some darker-than-the-rest grease is certain spots.
So I decided to put it all back together and look elsewhere for the problem when I came across this.

When I turn the pulley, it is tight with a slight jerky motion. It is almost like I can feel each of the gear teeth as they turn.

What I didn't note in the video, was that the tigtness issue was only happening when the gear shift pin was all the way in (not sure if that is forward or reverse). When it is all the way out, there isn't a tightness issue.

I removed the cover several times to see if anything was out of line with the pulley gear, but it seemed to line up well and none of the teeth on the gears look to be worn or broken.

I was just curious to see if anyone has come across this when put a trans back together?

Thank you AGAIN for the help!
Where can I send the case of beer as a thank you? lol

I found an exploded view of the transmission:

Parts and Diagrams for MTD 13BP605H755 (2007)

I've never had one like yours apart. But a couple thoughts come to mind, the grease might be dark in places if it is full of very fine powdery like metal shavings. Those spots would be a good place to take a second look for something worn or grinding. If it binds up when tightening the cover (worse then it was originally) that probably means something moved out of position, a bearing, gear, etc. when you opened it up. That can be a real pain to figure out what is causing it when your not experienced with working on similar models and know by heart were everything goes. Also as two gears wear the teeth can round off enough to where they try to push apart from each other instead of meshing. At some point they just start slipping and grinding and worse case loosing teeth. The bearings that hold the gears in alignment can also get sloppy enough with wear to allow the gears to slip and damage teeth.

Thank you once again.

I am thinking that it may have to do with part #9 against part #15 (left side) as it doesn't seem to have an affect when it is against the right side.

I never thought of the darker grease possibly being ground metal. I will look at it again and see exactly where the darker grease is.
I am thinking of possibly just replacing parts 9 and 15 and see where that takes me, as the rest of it seems to work pretty well (from what I can tell).

I will keep you updated!
