I appreciate the video Rick, in case I need to adjust my riding mower. You made it look easy enough without taking it to a shop. Thank you Sir!

[@RickMammana]

I was hoping to see you riding home from where you bought it.

[@jimwilson7824]

@@RickMammana I bought it 15 miles from my house. I drove it off the delivery truck!! Cut an hour off my mowing time. Maybe I’ll drive it up to the Pizza Hut a quarter mile away from our house. 😊👍🏻

[@RickMammana]

👍😎👍

[@lovelife7249]

Whoops, he's got a problem here. Not to worry John Deere Wildman will take care of it. My husband has to do the big servicing to ours every year. We have a lot of property to mow. He always has to sharpen the blades as well. He sure does love his John Deere too Rick. 😎

[@RickMammana]

It's so much fun riding it around. 👍🙂👍

Great video great tips hello Rick and Kathy

[@robertcheslock9636]

Rick, that puts tension on the blade startup. When you disengage the lever releases tension allowing the blade brakes to rub against the blade pulleys. Sounds like the one blade brake is sticking, not stopping the blade. Look a little deeper. Rust or debris not allowing it not to work. With the tension off try to turn both pulleys by hand. The one that will turn is the side not engaging the brake.

[@RickMammana]

Thanks!

[@marktaylorp]

Hi Rick I’m afraid that might not be a fix. I have the same mower. That’s a tensioner adjustment for allowing the blades to engage but if one blade spinning freely it’s the blade brake that’s the problem. I took my lower deck off which is simple and had to replace the spring that pushes the brake onto the pulley when you disengage from above the break stops the blades from spinning when it pushes on the pulley. But perhaps it was only the tension cable.. Love your videos!!

[@RickMammana]

Thanks! Well if I need to replace the brake it sounds easy. So far the blade stops like it should.

[@kylewolfman]

Hey bro my d105 auto has that bracket you adjusted welded on not bolted....

[@RickMammana]

Yeah I heard some of them are like that. Maybe there's a similar adjustment in a different spot. Sorry I don't know. :)

[@curtrich7773]

Yeah, my E100 is welded also.

[@RedGrayBeard1218]

I never knew that. I just replaced the belt. Plus I caught the front rim are they chrome.

[@RickMammana]

Yeah mag wheels! 👍kzbin.info/www/bejne/mHKkknyGhbCseck

[@adamf4196]

Helping a friend, thanks for the info.

[@RickMammana]

No problem 👍

[@marksreviewsandrants8554]

I have a TROYBILT riding mower I have had since before 2013,so far I have not had to replace the belt,I dread the day I do,the whole deck has to come off,I have had the TROYBILT push mower before that.

[@RickMammana]

The deck might come off easy.

[@tommywalker742]

Good job!

[@RickMammana]

🚜 👍

[@alllivessplatter1311]

No need to remove the cable from its mount. Loosen bolts and slide it back with cable in place.

[@user-fl1pq4zj8n]

I need to tighten my cable. It’s so loose the blades won’t ingage.1/17 pm

Time 2 For John Deere Tuneup If needed

[@tundra5568]

I need your input. I put in a new deck belt. Now when I engage the PTO/blades and lower the deck the engine loses power. When I raise the deck engine runs stronger. If I don't engage the blades engine runs fine regardless of deck height.

[@RickMammana]

Hmmm all I can think is just maybe a spindle or bearing is bad and with the new belt it's tighter causing more force on the spinning blade slowing the motor.

[@ThrowAway-lk2se]

@@RickMammana This is exactly the problem I'm having as well. I don't know about lowering and raising the deck, but as soon as I engage the PTO, the engine loses power drastically. It also rattles and vibrates a lot. A bad bearing or spindle seems reasonable. Any suggestions how to fix or replace one, or even identify which spindle is bad? Or would you recommend I take it in for service?

[@RickMammana]

@@ThrowAway-lk2se Yes if you can't identify the problem I would take it to a shop. The deck seems real easy to remove although I haven't had to do that yet. Best of luck with it.

[@fredmccurdy7844]

Mine's welded right there then what do you do

[@RickMammana]

I'm not sure maybe the is another adjustment like on an idler pulley.

[@wiwingmargahayu6831]

wow

[@DavidMartinez-si9yq]

How do you adjust tension on drive belt on jd d100 riding mower

[@RickMammana]

I'm not sure if it doesn't have an adjustment like this one. I'd look it up. I know you probably are.

[@markbeck3115]

What year is your tractor Rick?

[@RickMammana]

2015

[@markbeck3115]

@Rick Mammana Very Interesting. I have same thing but 2016 . I watched ur video , went out to adjust belt and where u loosened the bolts mine doesn't have bolts looks like it fixed to the deck!

[@RickMammana]

@@markbeck3115 Hmmmm

[@markbeck3115]

@Rick Mammana I'd show but don't know how to post pics on here

[@RickMammana]

Is the an adjustment on the end or the cable?

[@RichardMcMurry-nk7en]

Bracket looks aftermarket. Mine is factory welded to the deck and you cannot move it!

[@RickMammana]

That's how it was new. ?

[@Yahhwayy]

Have the same problem

[@user-gg3nw1mj4r]

What if the tensioner is already back ad far as it will go?

[@RickMammana]

Then you might need a new belt.

[@user-gg3nw1mj4r]

@@RickMammana went thru 4 belts. Belts are loose when i install but tensioner cant go back any further.

[@axion3979]

@@RickMammana im having this same problem, my belt is extremely loose and it feels like it should have a 40 or 41 inch belt even though i know its a 42 inch deck and calls for a 42 inch belt, the tensioner is already adjusted as far back as it will go, do you think the cable could be damaged and just needs to be replaced as well?

[@marksreviewsandrants8554]

Rick did you see that movie years ago about that guy traveling with the john Deer mower?That was based on a real life story,I liked it.

[@RickMammana]

Yeah i forget what it was called.

[@TEXAS-SMITH]

Mine is welded.

[@southerngunnut5661]

Mine too 😑

[@tory464]

Same here
