Huskee 42" 16.5 having issues with belt/deck.

As far as i know,mtd makes huskee,if im wrong please move this where it needs to be.


So,i have a 42" deck huskee with 16.5hp engine.


Well,it was free. it was left outside in the weather and some water got into the cylinder and rusted the rings a little to the cylinder. He said the engine was seized. Well,needless to say i got it knocked free,and used it for about 4 months. Well,i snapped the "teeth" on one of the spindle shafts. It sat for about 3 weeks. Well today i got another spindle shaft for it and replaced it.


Now,when i went to mow the grass,which is 1ft high. The belt/deck seems to have some big issues. I hear squeaking and the deck (not the engine) bogs down to nothing. Seems like the belt is slipping and causing it to heat up. I smell what i believe is rubber and i see a lil smoke. If i let it sit still,with the deck engaged i have no issues it spins like i should. As soon as i start to roll the deck bogs down and i have to stop and the squeaking begins. I believe the belt is the issue. Just doesn't make sense since it was fine until the spindle shaft snapped.

Is there a belt tensioner on these puppies? With the deck disabled both pulleys spin fine. So i rule those out. When deck engaged theirs tension,everything turns,but there is some flex in the belt. Oh yea,belts hot to the touch.

Please help. Im being hounded about the yard which i dont blame em. Ive got 45.00 in this mower,so im not too mad about it.

honestly after rereading this it sounds like the grass is too thick. It has been raining a good bit. It hasnt for 2-3 days though. Is it normal for mowers to do this? Ive only ever owned push mowers,so these riding mowers are new to me. grass is a good thick 1ft high. i tried going as slow as i could get the mower to go,but it'll still start squeaking a little and the blades will bog down.

I assume you are in the highest cutting level. There is an engagement adjustment so you maybe need to tighten things up for that grass. Do you have a neighbour with normal height grass where you could test it? No tensioner on the deck belt. Make sure the belt is not routed on the wrong side of any guide pin.

It was indeed on the highest cutting level. I dont think the belts installed incorrectly. when i did the spindle all i did was bust the pulley nut loose,remove the pulley and the spindle,and laid the belt down onto the deck. It was the "driver side" and i dont remember any guide pins on that side.

" There is an engagement adjustment so you maybe need to tighten things up for that grass"

Please explain. thanks!

Chris, when you replaced the spindle, did you make sure to reassemble it in the proper order? By this I mean is the spacer under the pulley. If you put the spacer on top of the pulley, it will misalign the belt and the pulley will rub on the deck, making squealing or ginding noise. Or it may not turn at all and the belt will still spin the other blades by slipping past the pulley.

spacer? didnt have a spacer,the only thing i could think of that could be what you are referring too is the pulley its self. Its ofcourse got that splined center piece,on the bottom of that centerpiece is a "spacer" which is part of the pully its self. I believe this is what you are talking about,and yes its reassembled correctly because if i would flipped it the pulley rubbed on the spindle housing.

I just came in from playing with the mower. Tried cutting part of the grass i cut last night. It did better,but the deck still bogged down.This grass is super thick,wet at the bottom and i believe the belts just worn enough for it to slip on a heavy load. I dunno. Maybe i put some wear on the belt when i hit whatever it was i hit when i snapped the teeth off that spindle shaft. Before this everything was fine. I looked at the belt a little closer and with it deck engaged its tight,but i can push it in about a inch or so. With the deck disengaged it flops around 2 or so inches.How tight does this belt need to be?

If you look on page 16 of this pdf manual, you will see the spacer I am talking about. Item 31. It sits on top of the mandrel bearing.

hmm. mines 98 model

model # 13a66693g131

from what ive found i dont have that spacer.
Looking at an older model deck here http://www.cubcadetsuperstore.com/p...2000)/Deck_Assembly_"G"/0091900-X/00919000011
It does not show the spacer.

I think you may have listed you model number incorrectly. I can find a 13a6693g131 as a 1998 Huskee.

Here is the parts explosion http://www.jackssmallengines.com/Jacks-Parts-Lookup/Model-Diagram-List/MTD/12970 No spacer is shown here either.

It does seem you belt is tight enough by the way you describe. See how she cuts when it dries out someday.

Here are your manuals at MTD http://manuals.mtdproducts.com/mtd/Public.do
Type in your model number 13a6693g131 and a serial number of 1 to list all the manuals.

but it is a huskee that model number i posted is whats on the mower,i triple checked...its 17 hp also,not the 16.5 i said it was.


So,from what i can tell,the belt tightens when you drop the deck,it pulls away from the engine pully thus tightening it. I tried it at lowest setting,(farhtest away from the engine) it worked better,but not as good as it should of.

Im gonna call a bad stretched belt is the issue. I found a belt for cheap online for this thing and once i install it we will see. I pulled the mower up and spun the spindles,both are free,brakes as well. so ONLY thing possible is the belt and theres nothing else to thing thing to malfunction.

I agree that you may have posted an extra six in the model number.as suggested download the manual for the adjustment procedure
oops i did. Well,sorry about that lol.
So,i found there is indeed a adjustment. Its a rod on the back side of the deck. When i removed the cotter pin the rod just flopped around. I turn it and it feels like its doing nothing. Is there a nut/or a spring above it? I cant see unless it remove some panels.
Ok,i removed the upper cover below the seat and discovered a huge sping,thats broken. it runs to the front left side to one of the arms that run down to the deck. Could this be my issue? what the heck is it? its about 12" long. one loop is longer then the other.

found it. part # 39

Is this a stablizer for the deck? I noticed that side is shaking and making crazy noise. would it contribute to the slipping belt?

That is definitely the problem.

Kincer,what is this spring for?
Helps keep deck aligned, from what I can tell.

im guessing this can contribute to the belt.

That sounds like the spring with an attitude that I repaired on a neighbor's mower several years ago. It hooked to somewhere back on the axle area if I recall. To stretch it and hook it on, I clamped vise grips on it, tied my ankles to a tree with a big rope, laid on my fat belly and had the wife pull the mower forward with the pickup truck. :sidelaugh Well, so this is exaggerated a little, but not much.

Yes it won't work right without it, every spring has a purpose on there.
