Doodle horse build

[Shed 263]

So with the destruction of the transmission is my suburban, I have decided to build something a little different and it's a little safer and easier for my kids. So I am building what I call a doodle horse. Ideas are from the doodle bug conversion in the past. I am extending the frame rails and mounting the engine behind the seat. I went with a belt drive tourqe convertor that drives by chain a forward and reverse gear box to a soild chain drive axle. It has one mechanical disc brake which I will use the original brake pedal. The whole tractor will be much longer then original so I wanted to make it look not goofy so I am cutting some rough cut oak boards and building a simple bed frame, steel frame wood sides and flooring. Here's some pictures. Don't mind the mess things have been crazy and I'm trying to finish this before the local show. I'll post more. I'm still waiting on the axle frame rails need to be finished tonight.

@Shed  looks interesting , loaded with opportunities , often refer to  ROLLER STOOL ING AROUND , a problem  area , for insight / ideas to  improve  function , done a lot of that , looking at a REPEDITIVE PROBLEM  AREA , what can you change / improve  ? a 5/16 steel brake line, inside the  corner of that frame , would eliminate a lot of  fuel hose break down , very easy to swage , a barb for  tank to carb set up , of course a filter close to tank / carb , how about a HEIM  JOINT  at a sloppy connection  spot to make it  seamless ? have a number of those , seamless  transfer of  function , WHY NOT ? good luck with that , improve as you go , pete

This should be interesting

Many Doodle Bugs can be seen at the Big Show.

 

Here's mine.

Looking forward to your build.            You will need to add a lot of weight to the front end to prevent wheelies.

You mentioned a solid rear axle.  If you mean that both rear wheels will be driven by the axle, steering this machine will be an issue.  You will need a differential of some sort to be able to steer the machine.  The simplest 'differential' is to drive just one wheel, and let the other one freewheel.

Yeah I'm going to see how it goes many go karts I had growng up were straight they pushed a little. If I have to I can change it around. 

 

Yes lots of front weight.

 

I'd like to put a chain driven genorator to charge a battery and I'd put the battery up front. My son loves lights so I'll see. 

 

I'm stretching the wheel base a good bit so hoping that would cam the wheelie  it down

 

He will just be happy to drive around helping out around the frame. He can take supplies to his chickens then in the body

Around here, there were many Doodlebugs made from 1920's cars that became the poor man's tractor.... Mostly at the southern end of the State down in 'Tater Country.

Wicked cool 😎 👌

Thoughts should I try and reuse the original fuel tank on the wheel horse? I get running fuel line over to the engine but it will only be gravity fed or is there a way to put a diaphragm pump on a 79 cc predator engine or if I was able to come up with a charging system for a battery I could run an electric pump.
