How to make this in-row cultivator selfpropeled???

[foler]

hi
How to make this in-row cultivator selfpropeled? Want to make job myself, without tractor and driver. Need power for rotors and wheels. Maybe electric with small generator?

I would think that it would be wise to use an existing tractor like a farmall cub. That way you don't have to make what is already been made. What ever you do you are going to have to control the steering, speed, and the cultivator. Maybe you can do something with your teeth. Not being mean just saying it is going to be a trick. Ed

Two wheel tractor on front, steered with your feet?

Something like this:

Why not just use a one roll cultivator on the tractor, it would do the same thing.

How about something as mentioned with a Farmall Cub, or..., and Allis Chalmers G. Mount the framework on, then hydraulics to power the weeders, and move them in and out. Drive with one hand, and a two way wobble stick to move the weeders in and out. It may not be as efficient as the one pictured, as both weeders would only go out as far as the one nearest the plant, if you happen to be off center a bit, or row not perfectly in line.. Not manual independent like the one shown. I'd say it would keep you plenty busy..!!

Hhhmmm. Only way I see is hydraulics. Pump ran off engine and hydraulic motor on 2 drive wheels, steering up front, then a motor to the tines and a valve that had a 50/50 splitter on it to 2 small cylinders moving the tines

I think making it self propelled would defeat it's purpose of have an operator to control the spacing of the tillers. If you want it self propelled just fix the distance between the tillers by immobilizing the handles and then put stabilizers on the 3 PH arms, then just drive the tractor straight. A bobble would then uproot your plants but it would be self propelled.

It is a pretty ingenious piece of equipment as is but a little labor intensive. It does look to be much faster and easier than a gooseneck hoe though and much less likely to destroy your plants than a standard cultivator attached to the tractor.

If you made a mount under a cub or A and put the rotors on hydraulics so you could move them in and out with a lever. They would move in and out the same, not one or the other. I don't know how well it would work but it would be doable. Ed

Two wheeled tractor, something like a BCS, with a foot steering bar? Pick your gear/throttle speed to what works, then just drive. If things get beyond what you can control with your feet, take your hands off the cultivator controls to put them back on the handlebars and readjust...

And if you don't already have a 2-wheel tractor, it should not be difficult to come up with some similar arrangement. A small engine (gas or diesel, whatever you have that is common in your area something in the 5 to 10 HP or 4-8kW? range would be cheap to run), a v-belt off the motor with an idler pulley clutch into a series of chain reducers to get your desired speed. Including a manual shift gearbox may be possible depending on how creative you are. A solid axle with no differential is probably good enough, and if you can't get tractor tires a set of snow or truck tires with a coarse tread (or tire chains). The frame only needs to be enough to keep everything in the right relation to each other. The connection of the tractor to the cultivator is used as a steering point side to side (controlled with your feet) and also keeps the tractor part in place from tipping front to back.

Search on "Planet Jr." or "2 wheel tractor" or "walking tractor" for ideas.

Drawing off power to move the machine and run the cultivator tines is left as an exercise for the student...might also mean that more power is needed than my initial estimate.
