this is a 8x8 at the end... perfect forest machine, all donn by himself, can't wait to see this beast loaded in deep snow or mud :)

many tools, many materials, many projects, many ideas, this channel is just perfect

Brilliant. I think I would have used two drive sprockets and two chains in the walking beam though. Stronger and less chance of the chain slipping on the drive sprocket.

I'm sure you're already 5 steps ahead of us but you may want to rethink your drive chain setup. The single drive sprocket on each side will have very little engagement with the chain as drawn and is likely to skip.
Easy fix would be to double up the drive sprockets or add idler sprockets in between the drive and driven sprockets to pull the chain down around the drive sprocket for more tooth to chain engagement.

Great 3D plan for the gearing. Having worked with sprocket and chain set-ups, you need more contact of the chain and the sprocket on the drive gear. If it gets a little loose it will skip over the teeth of the sprocket. Maybe a set of tension idlers to give more surface for the chain to grab. Love your engineering.

Been looking forward to this!! Really interested to see how well it will work.
Wonder if it will need a clutch to separate the trailer drive from the sxs….just thinking out loud. 😂

Awesome work! Just gotta make sure that universal joint on the PTO spline is centred with the towball/pivot point for the trailer too!

Please Donn tell me something I've been asking myself since I started following you:
What are you doing for a living!
You never stop to amaze me!
You seem to be able to create anything!
Yet another Awesome serie coming to life!

Thats amazing your 3D CAD skills have improved immensely, you should do tutorials. What package are you using?

Recommend two idler sprockets on each side to hold the chain downward onto the top of each center drive sprocket to prevent slippage on their teeth. Will also allow chain tensioning.

Yeah this is going to be epic!
Can't wait to see it come to life.

You might want to be aware of the problems Land Rover had with the 101 Forward Control when hitched up with a powered trailer. They found that in some circumstances if the 101 lost traction the trailer could provide enough push to tip the 101 over.

Nice idea, using the walking beam suspension. Waiting on this one again. Keep them coming Donn.

I hope you have enough teeth engaged on your drive gear to end up not skipping under torque. You may consider a separate on the drive sprocket for each wheel. Just a thought, I love watching your ideas really get made!

Best I can claim to have built was turning an old 2 seater go-kart frame into a flat deck trailer. Grandfather still uses that cart to this day.
I look forward to seeing this build.

Very cool work in Fusion there…some axle rotation attachment I have never tried.
You might want to test out a 3D mouse. It helps a lot.

So cool being able to work in 3d and figure out all dimensions before hand. Assembly becomes more of a Lego build with mostly fun

With a single chains per side, if one is broken you lose all drive capability. With no resistance your spider gears simply spin. Thoroughly enjoy your videos and projects. keep up the good work

Hi Donn,
I'm so excited to see you building this.
Can't wait.
All the best my friend.

Would be cool if you could avoid the diff and make a variable gear ratio depending on the angle of the trailer in relation to your vehicle. :)

Cool! Can't wait to see the finished product! 😃

Pure pleasure following your ideas and skills. Which software do you use for modeling?

Ты не устаёшь меня удивлять, как всегда всё на высшем уровне 💥👍🏻

Fantastic, looking forward to a really cool fabrication set of videos Donn. It's gonna be great !!!! Fred

3D Modelling.... WOW!!!! Donny getting a bit flash this year Mate. Hope you & your family had a great Festive Season. Looks like you're stepping up the pace a bit with this build. Can't wait to see it in action. Thanks for sharing your skill & commitment to great video's. Billy J... Tropical, Tranquil Sunny Queensland, Australia.

That 3D modeling is super cool Donn. I wish I had the brains for that kind of stuff.

This reminds me of the chain drive setup on a skid steer. Except those have 2 sprockets on the drive shaft to allow separate chains for the front and back wheels. Doing it that way would give a lot more chain engagement on the drive sprockets.

Excited to see the rest of the build!

Ficou muito bom 👏

Nice to see you back Donn. I have a question for you, do you still have the trike you built for log hauling?

Great project! I think I would try to just double the back wheels like in 3:10. Wouldnt that work?

Donn, watching your tracked vehicle video inspired me to get into fabrication.
I did not document my build as heavily as you did.
There are some videos on my channel if you'd like to check them out.
Thank you and glad to see you are still building.

Just an idea:
Make the suspension completely free-floating in the forward-backward direction - so it can move up/down and forward/backward and is only supported by two springs with dampers 45° forward/backward and a support that doesn't allow any steering movement (right/left). The drive could be done by a chain with a strong tensioner. This way the suspension can physically move backward on impacts before crawling above the impacted object. This will mitigate that the trailer steers to one side and shifting the back of your vehicle to one side, too.
This is not conventional, as it's not suitable for any high speed, but at such low speeds you're planning to use it, it shouldn't matter.

Спасибо новый проект, отлично. 👍

This is really an insane idea. I love it!!!

Great video as always Donn! what ever happened to the tracked amphibious vehicle? I would think that would go great in the snow!

I had a dream about one of these and also have a idea that I would love to have you build. Its remote steering for axles on trailers that you control so that the trailer you tow won't cheat on the turn, it will follow the tracks of the rig pulling it so you don't have to turn so wide to get around corners .... like semi's will presently have to cross into the next lane to go around and the trailer not "cheat" and go over the curb behind it. I know how to make it perfectly

This will be a truly epic project! It needs a name like “tankenstein” or “wood slayer”! I love the duel independent bogie suspension that will be very handy.

O cara tem todas ferramentas na casa 🏡🏡🏡 dele facilita muito 🇧🇷🇧🇷🇧🇷

Wow your shop and videos sure have come a long way since the first one I watched which was the logging arch I believe. Great work.

A new video from my favourite YouTuber! Great!
And on a topic I can relate to. Both forestry and trailers for working in the forest. I have one comment here. Please do take great care when operating this trailer. Both the Land Rover Forward Control 101 and the Volvo Felt military trucks had PTO driven trailers. This led to some very interesting accidents where the truck started loosing traction with the trailer was powered up. The trailer alarmingly often pushed the truck over on the side, or off the intended track. Something to have in mind :-)
Cool video! Looking forward to see the hydraulic crane on it. I purchased one a year ago and boy is that something that really helps both in the forest en elsewhere.

This is going to be such a brilliant build! Thank you for sharing! 🙂

Как долго я ждал что бы узнать для чего нужен был вал отбора мощности ))) очень нравятся твои видео!

Excellent - something to look forward to over the coming weeks. Was trying to figure out how you drive two wheels from One sprocket but assume it’ll just be one long chain that wraps round all 3 sprockets. Also, I have no idea how you make sure the wheels on the trailer will turn at the same rate as the atv - guess the bmw diff had the same ratios as the one in the atv?

Pretty sweet project mister. All that flipping n flopping of those parts around made my head spin. Hahaha. Im amazed at the talent you have bud. I really like seeing what yer doing over there in your part of the world. Keep up the great job. Ill keep watching. Greg in Central Pennsylvania

This is going to be cool! Good to see you back

Looking forward to this one. We shared this video on our homemade tools forum this week 😎

I recognize that CAD software , something from Autodesk for sure ;)
Very interested to see the rest of this!

Does the PTO rpm vary with the engine rpm/which gear the UTV is in? I'm just wondering about the trailer overrunning the UTV or vice versa

Incredible design. I love this channel.

Not a new idea, but it a great project. Sure will make taking fire wood out easier. Will a pleasure to see it work!

Great, new build. I have a thougt about the boogie Axel design. Lets say that you lose tractio on the UTV, and the trailer with boogies and wheels have traction and tries to push. The risk is that the rear boogie wheel will push and the boogie will climb and lift the trailer and front boogie wheel. On heavier boogie axeled maskins the boogie is connected to the chassie by a planetary gear set to prevent this.
A suggestion is to move the boogie tipping point forward closer to the front wheel so that you get a longer torqarm regarding the rear wheel and you will need more wheel torque to lift the front wheel/trailer.
Keep up the god work @donndiy

Love it. Was wondering would u need an idler for the chain sir? Maybe you havnt got to that stage yet😀. Your UTV an this trailer will be hard to stop🤙

Good Idea using the same wheels. You can put one of the trailer tires on the ATV to get home even if that means leaving the trailer until you get the tire fixed.

some of the best videos on youtube. Great content. YOu need to do this for you dirt bike "2020 Timbersled Ripper" Would be a cool project to make the track for it.

Hi Don. The best Way to make This is with 2 chains in each Boogie axel to get rit of the problem with chain slipping and the other thing you can get out of it is more clearens between the wheels so you dont get stuck on a stomp or stone..
If I where you.. I would make the Boogie section look like a booomerang seen from the side and put 2 chain sproket on the center axel .. hope you understand 😊
I like your work and idieas

The internally driven walking beam is brilliant.

Get chains for your tire, they help the pulling power significantly.

Hey, nice Idea. I am wondering though what program you used to assemble the parts? Would quite like to get into 3D modeling myself

A good project for the future 👍🏼 but is the engine strong enough with the more weight?
🙂

I am very intrigued. I can't wait to see this finished .

Świetna robota bardzo podoba mi się to co tworzysz

Интересный проект. Буду с удовольствием наблюдать за изготовлением. An interesting project. I would love to watch the production

The wheels are awesome! 💪🤜 built tough!

Donn just a suggestion for a future project that I'm sure you will use.... tire changing machine. If anyone can design one I am sure it is you. Thanks for the videos they are appreciated!

I would have gone with the Skidsteer/Grader style of chain drive. Yes it is, lower ground clearance, but, tooth loading on the drive sprocket(s) is lower, shaft load is the same, and the chain stresses are spread out, not all on one length, but two/side. This system, will give awesome power in the woods, as you will then stretch the trailer, to haul more.😊
Can't wait to see the rest of the build.
Best wishes from Northern Manitoba.

молодец хорошая работа !!!

as configured in your CAD the chain is likely to slip because of the limited contact area and the angle, you be better off with 2 sprockets and a separate chain driving the forward and rear wheels. have you already worked out the gear ratio? thats a bit of math I wouldn't want to tackle.

Awesome CAD dynamic illustration.

Very interesting, can't wait to see it

Absolutely awesome build

It might already been said, but the wheels should not be on equal distance from the centre axle. That will make the boogie climb over rocks and logs poorly. The front wheel should have a larger distance to the centre than the rear. Since you are doing it in CAD first now, it is easy to change the design 👍😊

This should be another great build, 👍. You are a very talented young man, your videos are always a pleasure to watch, keep them coming.

Looking forward to this. Will be interesting :-)

Probably a bit late to the show, but in earth moving trailers with a simular kind of carriage they offset the pivet piont of the carriage to the rear. This gives the front tire less preasure (Force*length of the arm) so it will be easier to pull in difficult conditions because the wheel will be les likely to "dive" into the Material you are driving over.

I love the idea, however I believe there needs to be more support for the bogie wheel end. On graders and forestry equipment there is a large radial bearing to support the load weight and thrust. I also agree with other comments about using two separate chains to drive the wheels such as a skid steer or grader. Perhaps a much more simple system of using a drive tire centered between the two bogie tires like are used in a muck truck powered wheel barrow would accomplish the same ends and simplify the build.

3D modeling really helps. Best as you go forward.

Can we take bets on what each side will weigh without wheels? 😁 I’m thinking easily 40kgs

Snow chains for utv and tracks for trailer, and that will go up to a tree 😉
