Belts snap sooner or later. Glad to be of help. Thanks for watching and commenting. Happy mowing

Thanks Mr. Wilson. I certainly agree that a helper would be great. I’m use to working alone. The 2x4s is a great tip.

Awesome, I’m glad it went smoothly. JD seems to be proud of everything. Thanks for watching and commenting. I sincerely appreciate it

Thanks. I don’t remember how old that video is but the belt I put on in that video broke last week. I had to rewatch it again myself! Thanks for watching

Wayne Vowell glad it helped. Now I need to change the oil.

You and me both.

Roy Batty you are so right!

Great! Glad I could help. Happy mowing.

Steve Godsey fantastic! Glad it helped. Open end wrench is a great idea, sorry about the knuckles 🥴

Jim F thanks, hope it helped. Happy mowing

I agree that there is some confusion on parts list. They put at least two different motors in the X300 the year I bought mine. If you don't know the serial number when your looking for parts you can end up with the wrong thing. Thanks for watching and happy mowing. Stay safe. Larry

Thanks M J. “Rob dog dealers”, love it. Have a great summer. Larry

CurtisDrew1 same here, that’s exactly why I mentioned those notches, I’ve messed up there before! Good luck

Larry Satchwell I learned that today. Must of missed that part before. Normally I had someone helping me. But not today so I was able to pay more attention to the small stuff. And hit replay if I wanted too.

Well it thought yesterday that since I was waiting on a new belt would just clean the deck while it was out, sharpen the blades again and grease up the spindles. (I had it hung on an overhead winch on an I beam in my shop, so it was easy.) When I put my grease gun on the left spindle the grease zerk pulled out.( the kind that mounted on the side of the spindle housing) Stripped at the factory I guess. Decided to unbolt it so I could replace the grease zerk and 3 of the 4 bolts that hold it to the deck snapped off. They refused to e-z out of the spindle housing. So rather than tap a new grease zerk and drill out the broken bolts I ended up buying a new spindle to go with the new belt. Sharpened the blades and just got it running again a few hours ago. Cuts good. Was going to just drill through the old broken bolts and retap it, but didn't feel like messing with it. The new spindles have the grease zerks in the top of the spindle bolt. I would have missed the notch on the retainer rod too, but your tip kept that from happening. Thanks again.

CurtisDrew1 wow, you had some trouble! Glad you were able to work through it all. Good luck for the rest of the summer.

The Church In The Home fantastic, glad it helped. Happy mowing

Blake's Garage thanks and thanks for commenting. Happy mowing!

You’re welcome, glad it helped

Great, glad it helped.

You’re welcome. Just had to change mine again last week. Went with an off brand this time, almost 1/2 the price of JD. I’ll do a follow up after I see if it last or doesn’t last.

Thanks, I'm glad it helped

Jason C you are welcomed

You’re welcome. That little notch bewildered me too. Glad it helped.

You’re exactly right. That’s what happened to me the first time it broke, 5 weeks! Thanks for watching and commenting, your feedback is much appreciated.

Haynes Poole thanks. Hope it helps.

Just used the video to change the belt on JD X300, Greatly appreciated!

weldyn1 great, glad it helped.

Thanks, that's good to know. I'm going to do that the next time I have the deck out.

Thanks

Kenneth McLeod it sounds like the same rabbit trail I went down. In fact I’m sure I have a pair of perfectly good coils in my parts box. So, there is a small needle valve in the carburetor. It has a little rubber tip on it I think. Anyway, you can sit and let the mower idle for hours and then you move it and it might run for 10 minutes or 2 minutes then stop. The valve has dislodge and you get no gas. I didn’t rebuild the carburetor so I don’t know exactly where it is but my guy says it’s only a $10.00 part. Good luck, hope this helps, please let us know. Larry

Good luck, you can do it and save lots of money

Lisa Armstrong thanks for your nice comments and for watching. I’ll try to show that soon.

Deemn FSH my problem was a needle valve. I don’t remember the parts name but you need to get into the carburetor itself to change it. As I recall, it has a little rubber tip. It would idle for hours if not moving. Sometimes it would run long enough for me to cut the lawn, then sometimes for a few minutes. The valve would wiggle out of place. Hope this helps.

Thank you Sir! I appreciate you!

zoeybean1 I love it.

David Lockhart good luck. As for the clean underside, not sure, I never clean it 😁

Brad Stribling you and me both! Thanks for watching

I gotta agree with you there for sure.

Michèle Jedlicka I went round and round with the John Deere dealer and mechanic for months and spent several hundred dollars. Long story short. I took it to a different mechanic, he knew exactly what it was. I don’t remember the name of the part but basically it’s a little needle value that regulates the gas flow. It’s a $10 part but they have to rebuild the carburetor to get to it. The part is about a half inch long with a rubber tip as I recall. Hope this helps. Happy mowing, Larry

That's very helpful. Thanks Larry and thanks again for the video.

Michèle Jedlicka glad I could help. BTW, I’ve not stepped foot in Ag Pro John Deere since.

You bet, hope it helped

driggs51 I wasn’t aware of this. No it hasn’t happened to me yet. I’ve had this mower for, I think, 5 years, maybe 6. I’ve replaced the belt twice. The first one broke because the idler pulley froze up. The second time I’m not sure why but it was several years old and I had been abusing it, using it like a bush hog in the woods. I’ll post a follow up if it ever does fly off. Thanks for pointing this out.

Brian Herbert thanks for the kind praise. Don’t get me in trouble with your wife! 😄. I’m not sure about the grease gun size. Here in the US I think they’re pretty standard. If you’ve gotten 8 years out of it I think you are lucky, it probably just wore out. Good luck I hope it goes well and quick, before your wife gets home.

@@LSatch thanks Larry - I will investigate locally. Maybe you could do another video on 100 hours servicing requirements sometime. “Cheers and stay safe”

Brian Herbert I did a maintenance video that I think covers that. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-oskC2lyTmPU.html Be sure to read some of the comments because as I recall I missed one of the grease points. Thanks for watching

powerboat20 ANTS! Have a happy holidays

I haven’t stepped into an ag pro store for years and have no plans on doing so in the future. Sorry it happened to you too

Eduardo Feliciano this is the belt I ordered on amazon. John Deere Original Equipment V-Belt #M154621 You may want to check to make sure you can return it if it’s not the right size. Hope this helps. Good luck. Larry

@@LSatch hi thank you so much for the help I order the belt it was a lot of help i really do appreciate you taking me to the right raod thank you again

@@eduardofeliciano9990 That's great. I'm glad it works for you. Happy mowing.

Wow. I found it online for $45 That was for John Deere brand. If you read through the comments you’ll find folks that recommend other brands that are cheaper. Good luck

Janice Mitchell wow, I’m not sure. Can you find a number on your old belt? Surely John Deere has a live chat or contact phone line. As a last resort, I’d make sure I could do a free return before you order one. Wish I could be of more help, sorry.

Pretty sure it's 146 1/4" for the 42" deck.

Janice Mitchell I hope you get my response, had a hard time finding the question in the video. I guess you got the belt. I’m not sure which pulley you’re talking about but..... if the pulley has angle on the inside, a V groove fill the groove with the corresponding part of the belt. Continue weaving the belt around all the other pulleys without twisting it. If it doesn’t have a twist in it you’re good to go. Hope that helps.

Larry Satchwell hi, I got a John Deere OEM 42" Mower Deck Belt M154621. I have the same mower as you. But I broke another belt today so I was just still wondering if that’s the correct belt. I’ve been watching your video again trying to make sure I’m putting it on correctly lol lol But I keep breaking belts more often then I should. I have a lot of dips in my yard so I don’t know if that has something to do with it.

Larry Satchwell is your belt a M154621?

Fonda Coffman you’re welcome. Good luck

mccullough87 I think the idler pulley is bad or out of line. It has happened to me before and it breaks the belts. I’ve never tried to fix the idler pulley.

mccullough87 yes me it’s getting frustrated. I’m digging more into it. I think I’ve broke like 3-4.

Janice Mitchell if it’s not a bad idler pulley I don’t know, but I’m not a mower mechanic. Searching RU-vid for x300 belt problems you’ll see a lot of videos. Sounds like a major complaint common in their mowers. Wish I could be of more help but I’m tapped out. Sorry

Larry Satchwell you have been a lot of help. If it weren’t for your video I probably wouldn’t have been able to change the belt on my own. So, thank you for video and help. I am so appreciate of it.

Janice Mitchell thanks, good luck. Please let us know if you find the solution.

You’re welcome.

I agree 💯 %.

Once a year, usually April 1st.

Thanks for the advice. My mower just turned 300 hours so it’s time for an oil change. Do you recommend any other maintenance at 300 hours?

@@LSatch i am weekend warrior too. I just found out about the bearings when mine seized up. Took it apart and found out the bearings where completely sealed. Then i talked with John deer and they said they all the decks come that way. So you can take a seal out an repack them or take the seals off and drill a small weep hole on the spindle so you no its packed with grease.

Indeed. Happy mowing

Great. Easy peasy once you’ve done it once. You’re right about service. They wanted my mower for 5 weeks. That’s when I learned how to do it myself

@@user-qn9nw7ld6j thanks for the review. I’ll try to do better next time.

Thanks

I couldn’t agree more.

Kurt Bally that’s great. Glad I could help. Thanks for sharing, happy mowing!
