Cub Cadet Dozer Build #11, Out of Control! 

Great vision good Sir. It's easy to sit at home and tell you what you should do. Your obviously quiet brilliant and you actually have your hands on it. Keep up the great work.

Just found you...........I love these types of videos Thank you for your time...........I m going back to the first one and watch them all

A trick a guy offshore showed me one time was to use a standard concrete bit in a drill press to drill through hardened steel. I have used that trick a few times and so far it has always worked.

Coming along very nicely! Can't wait till the next one!! Enjoy watching all your videos!

You've got do a vertical exhaust stack to make it seem more like a real dozer.

Very nice work on both the grader and the dozer

This has me glued into watching what get fabricated next.

The reason I love tractors is because of a 1970's Cub. Love your videos and your teaching! Keep it up!

I am thoroughly enjoying this build.

I have to take my hat off to you Sir. What a great idea that coming to fruition.

This has been a great series, fantastic! Keep up the great work!

If you use 7/8 tubing for the control levers you can use motorcycle grips. this is such a cool project!

Really enjoying the dozer build

Loving this whole series! Great work!

Nice video while recovering in hospital day 9. On the mend lowered my O2 again.

For the controls, could you put a plate above the pivot with a slot for the levers to ride in. Then put a detent for neutral. It would add friction to hold the controls in position and give a neutral lock out. Wouldn't be automatic but would be easy to find neutral in a panic. Either way amazing build. Looking forward to the next video

For the steering lever axle, use two bronze bushings inside the tube for the second handle. Just a tube over a rod will be yucky sloppy otherwise. My Dad built from scratch in the 70's what you are building. He also used chain for track but he used belts for forward and reverse. Unfortunately only part left is the seat. He turned 85 today and still making stiff. Love your project, brings back fond memories playing on the dozer as a kid.

I thought of an easy way to spring-load the two control sticks. You need some very long, light gauge wire coil springs. You need 4, two per stick. You arrange the pair one on either side, such that they are both in mild tension in the neutral position. Then, as you pull the lever in one direction, it stretches one spring, while relaxing (and possibly folding) the other spring. Release the handle, the stretched spring will pull it back until it's balanced by the other one. With some mild friction at the hinge point, it shouldn't bounce. The location of the spring's attachment to the levers will govern how much pull they have, i.e. close to the hinge, the pull is weaker, than farther away. Alternatively? You could use a pair of torsion springs, one wound clockwise, the other wound counter-clockwise (on the other side of the lever). You'd "wind" these on the pivot axle, securing one end against the lever, the other to a fixed point on the frame. The lever secure needs to be just resting against the lever bar, not in a hole. This lets the spring release, when pulled opposite it's tension direction. Thus, as you pull the lever arm, it'd 'release' from one spring, while pressing against the other, winding it around the axle. Each spring would need arms or the ends bent at 90 degrees, so as to press against opposite sides of the lever arms. The other end, could be a simple hook, fixed into a tab on the frame. The neutral point would be when both springs were relatively relaxed, keeping the arms in place.

Another good one Frank, really like your fluid system on the cut table too!

New to your channel and the dozer is coming along nicely. I've also read some of the comments and you are getting some good suggestions. I'd also like to make a couple. Check into heim joints for your control rods. They come in all sizes with a hole or stud ends and with both male and female threads. Some one suggested using throttle cables for the controls since you can fish them around obstacles . PTO cables like the ones you use on dump trucks are quite heavy duty and might work well. I always liked how the steering brake levers came out of the dash on the older cat bulldozers. Are you familiar with Walker mowers? they use a speed control lever. All it is is a lever that rests on and pulls the hydrostat control levers back into the neutral position. The hydrostat levers on the Walker mower are spring loaded to go full forward when the speed control lever is pushed full speed. what would be cool is if you could incorporate something like that to control forward speed then pull back on the lever in the direction you want to turn. On the Walker mower there is noting holding the levers from going into reverse if the speed control is pulled all the way back. Just some suggestions that might spark an idea.

This machine looks awesome and the plasma table is sweet. Hey you a magnet to fish out the cut pieces that fall into the table. I’m envious of your grandkids. They have a grandpa that can do some neat stuff

I look forward to the day you can say "Now, lets push some dirt!" you have a very strong design vision and the skills (and budget) to act on it

It's always amazes me how someone like you while designing and fabricating a project of this complexity will have those at their keyboard comfortable at home throwing all these better ways for you to do it. I'm sure some suggestions are appreciated, but if you are not actually hands on in front of the project it's impossible to cover all the bases with the variables that have to be overcome while tackling something like this. Can't they just say "GOOD JOB" without all the back seat engineering? Can't wait to see it operating. I enjoy your videos. P.S. I have ideas as well, but choose to keep them to myself until I am building my own. In the meantime watching you might just save me a lot of blood, sweat, and tears if and when I do.

Man I could hang out with you all day...

I suggest you look into using an adjustable clevis on each end of your push pull rods. I might also suggest gas struts for the centering of the levers like they do for zero turn mowers.

The grandpa I never had lol.. Sweet project man 👍👍

You should build the fuel tank and hydraulic tanks beside the seat, then you could put arm rest on top of the tanks. Look at komatsu bulldozers.

A suggestion on your controls, I would put both track controls on the left side of the seat, side by side to each other. You will find that you will always have your hands on them, making adjustments while you are operating. With this in mind, you will create a "dead man" control. In your right hand will be the dozer control, that will be in constant motion as you are operating the dozer blade. Love that plasma table!

thank you for entertaining us

Amazing work

As an operator. I think it would be great to be able to steer with your feet and keep your hands free to operate the blade. Mabe peddles in place of the leavers. Just a suggestion

I use an air chisel to take the dross off the pieces I cut on my plasma table. It’s quick and doesn’t eat through so many sanding disks, that dross isn’t on there very strong. I really enjoy the build!

Can't wait to see what this turns out like! Subscribed

This is a great big/little build so far. Thanks.

I Love what you are doing

This is amazing I wish cub cadet had actually built these they could go back to there old design using there old patents redesign and build something like this and make good money

You have all the toys I've ever wanted . . . .good for U, and your building my pet project. new subscriber, I'm hooked

I would recommend using some control cables like a throttle cable with a casing. It would allow you to fish it around obstacles between the drives and the controls so you don't have to have a straight shot. It would also provide adjustment and resistance to help maintain the control position. Here is an example from McMaster Carr 3125K518. One other thing, can you tilt the hood forward with the front blade brace so close? Not sure where the hood pivots. If you get a couple of magnets that you can place on the part being cut out has you get to a certain point, you can prevent it from fall through and causing the torch to catch the edge. Also easier to remove the parts. Your doing a great job. A lot to take into account. Thanks for sharing.

😂 I can’t wait for This to be done. Will be the coolest thing on RU-vid for sure. I hope to see many videos of it in action taking little trees down or something. Maybe like use it for small jobs as well like someone’s overgrown brush and use it instead 😂. Will for sure be super cool. Can’t wait

Hey man it’s looking better every time I see it. You doing a great job.

Looking forward to the armor-plating. You need to rename your series to "Cub Cadet Killdozer". RIP Marvin Heemeyer.

Can use copper pipe as a bushing to take up the slack in the rod. If you have a press and torch its an east job. Add a grease fitting as well

Look into keying parts together you make on the plasma table, makes it easy to assemble and weld....

You ever use nutserts? They work great for blind bolting parts together like your frame risers.

Suggestion for belt tensioner use an automotive serpentine tensioner

When plasma cutting, I would recommend that you program it to minimize the scrap whereby items with common edges (and edges that can be aligned) are cut with a single cut. Similarly, program the part so that one of its straight edges is the edge of the steel plate - thus eliminating that cut. For your control levers, they should definitely be designed with a neutral-spring return detent. This can easily be done with 2 extension springs on each lever attached in opposing directions.

Um u did great this time much much better but u did let um some ums out lol love this build ur a very smart guy looking forward to the build good luck!!!

I've always wanted to build a mini dozer like that but just never had the time. I really enjoy watching your work and look forward to seeing the new videos as they come out.

Great video! Following your build from uruguay 💪💪

I'm new to the channel. I really like this project and can't wait to see it run.

Cool build!

Who wants to see a wheel loader next? 😀

Frank, if you got a pair of 5/16" heim joints with long threads, and one LH and one RH nut, you could weld the nuts to a piece of pipe and get the same affect as the turnbuckle. One would only need one jam nut to keep them in place at the desired length. This would also be a bit more rigid.

Looks great......That would be great for my 10 year old son!!!

I think we're all in a long haul ☺️

Great build looks great so far but one thing about your plasma torch machine --it need to be away or above the water table in a safe area a major electrical safety rule is always in stall electric above water pipes etc. water to be dry out of danger of water splash.

If you drill an 1/8" hole as a pilot it makes it much easier to drill your larger holes by hand.

If the trunnions are up the other way hanging it will be forward for forward movement and vice versa would make more sense as your proposing would drive me nuts. If you can’t have them hanging it is still possible by running the push rods pass the trunnions to a small plate centre mounted to make a pivot and reverse the movement bolt hole top and bottom, lever to bottom hole and top hole to trunnions

Hi! I really enjoy watching this dozer build series so keep the videos coming 👍 I also like your weldingtable it looks to be a very convenient size, May I ask what the rough dimensions are on it?

Great build. Suggest putting in a pillow-block bearing next to the belt pulley on the hydro shaft to support it, rather than depending on the bearing inside the hydro. The existing support bearing (to the rear) is too far away

I do have one thing though, The blade, I worked at a coal pier for some years and we had D10's and D11's. When they came in new we had preformed stainless to weld to the forged blade. So can you get a blade forged made for you?

Very cool,….how do you turn the dozer left and right? …seems like you only have forward and reverse with that control set up? Pardon my ignorance on how those hydros work.

Schaut gut aus geste Grüße aus Germany .

I think equal pull springs for 4in backward motion with a detail for neutral

Hello, I really appreciate watching your Videos. But concerning episode 11 where you explained how you were going to do the bulldozer controls, the idea of ​​how to manipulate the controls back and forth makes a lot of sense. But nevertheless I do not know if you take into account that at certain times for the bulldozer to turn left or right both controls must go in opposite directions and this is something that would complicate the design. I look forward to the end of the controls design and the next episode. best regards from Puerto Rico

I'm not sure where you live but I see many hours of snow removal in its future if you get the stuff. Nice build. Terry from South Carolina

love that project it looks great. I'm just curious what the front hydrostat is for since your only doing one drive cog per side and said that you were going to make the front idler wheels yourself. I feel like if you put all you HP in to one hydrostat it would give you more torque need to push dirt.

Great build. Recent sub here about the time you started this project. Been trying to guess what state you’re in, based on accent, garage style, and garage setup haha as that’s all I have to go by…… maybe somewhere in New England???

Do you ever use nord-lok or Belleville washers on high vibration parts? I’m pretty impressed with both.

HOW ARE YOU GOING TO GET THE FRONT AND REAR DIFFS TO DRIVE IN DIFFERENT DIRECTIONS SO YOU CAN STEER THE DOZER , VERY INTERESTED IN THIS BUILD, I THINK IT'S GOING TO GREAT, WELL ALL THE VERY BEST FRANK.

A plasma table in your garage...dude!!!!

I get the concept of running one side of tracks off on rear end and other track off second rear end ....but if your only using one side of rear won't the spider gears just spin the side that's not under load or did you weld the spiders up ?

Could you use a turnbuckle for like a cable. Then just cut off the eyes on them and weld them to a rod of the correct length. Then use just a right hand nut to jamb it in place. Also, for the placement of your control levers, I would put the handle and connection point for the sleeved one on the inside. That way you have more freedom to place the handles and connection point where you want it. So essentially from your picture, I would move the left handle to the right of the right handle that is attached to the sleeve.

Thanks for the nice videos! Did you consider some isolation of the motor vibration from the frame or would this be unnecessary in a bull dozer with low speed and probably many other vibrations?

Maybe I missed something, but why are you over engineering the central shaft?! Just have it set in position and go through both levers with bearings,, or bushings and a set of collars with set screws on each side to keep the levers set in the desired position side to side. You can also bend the linkage rods going towards each hydro lever

You might want to put a shield between the plasma cutter and your computer. Sparks are getting on the computer.

What kind of paint do you use on the cub cadets

just curious.....since u had to move the motor and ur niw wirried about belt replacement on the drive belt...why not go with a chain drive instead?.

Why not use a cub cadet zero turn radius drive for the tracks?

Why didn't you use the drive motors for a zero turn mower.

Gday Frank , iam not familiar with the cub cadet final drives , are they open centre type differential or direct ( lsd) type ? If they are direct meaning both wheels turn at the same time like most tractors then how will you be able to have one track going forward and one back for turning the dozer ?

Maybe I missed it but how do you plan to steer it? With a hydro stat you can’t apply braking to one side right?

I feel like you really jumped the gun on painting

Since there is only a single direction trunion per drive axle, how do you plan on isolating each side to steer? Cant have one axle in forward and one in reverse pulling against each other. Just curious.

Has a ripper been juggled around as an idea?

Was this shot before the demise of the DeWalt or do you have a second DeWalt?

I'm still confused on how you will steer it. the right side needs to move separately from the left and visa versa. Not just front and back.

I have an idea for my dozer design, would you care to weigh in on it?

I have some big conserns whith how it wil work, maybe i am just not seeing it but here they are: I can't see a way you would want to control the front and rear axles at differt speeds, as they wil be connected to eachother by the tracks. If the front sprocket turns at a different speed than the rear one, there needs to be somthing broken with the tracks. And even the differential in the hydrostats wont make a difference becaus the other sides are connected to eachother too. Why did you choose to have two drive axles anyway? Real dosers have idlers in the front. And how are you planning to make it steer? With braking the side you want to stear to? Maybe im wrong and you plan wil work. But im not seeing it. Can someone explain?

👍🇺🇸

Why don’t you just make the hydrostatic controls on one shaft that just does forward and reverse. Make it a simple one shaft forward and reverse

I'm wondering how he plans making the dozer turn like a real dozer, when both hydros are going forward and reverse. A real dozer has a drive clutch on each side that can drive forward or reverse, thus, being able to spin around in its on tracks. Thats how you turn a dozer. If his drives will only go forward and reverse at the same time, he's not going to be able to steer it. It needs to be set up like a zero turn mower in order to turn.That would seem to me that it's only going to go forward or backwards and not be able to turn. Instead one in the front and one in the back, it needs two separate drives in the rear. One to control each track. I my be looking at this wrong, maybe he's figured out how to steer it with both hydros turning in the same direction.

one if by third two if by three

? How do u get it to turn???

cool small dozer Start at 5:40: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-r7cOfCR1xFo.html
