Backhoe Plans & Kit  FAQ

What tools do I need to built the backhoes?
You need the basic tools, electric drill, chop saw, grinder, cutting torch and welder.

How do I know which category of  tractor I have?
Look at the Chart below of this page.

How long does it take to built the backhoe 3PH-MID600 with the laser kit?
It take about 30 hours depending of your welding ability.

What are the advantages of building a towable backhoe by using the Power Pack
Model CL600 or Model LP20-CAT1 with the 3 Point Hitch Backhoe?
The advantage is that you can still use the 3 point hitch backhoe on a tractor or as
towable backhoe and the power pack can also be use for something else.

Can I buy the laser metal starting kit without the metal bushing?
Yes, you can make the metal bushings yourself and it is not difficult at all. In the plan it
shows you how to make them the easy way & you wont need a lathe.

What is the most time consuming when building the backhoe?
I would say making the parts are time consuming.

Is the plan always included with the laser kit?
Yes, the plan & technical support are included with the laser kit.

What can I expected to see in the plan?
I made the plan look more like a book than a blue print, it is easier to read and
understand & customers do not need an engineering background.
It includes the Bill of Material, List of steel, 2D & 3D drawings ,
All part numbers for the laser kits & step by step assembly instructions.

Can I use bigger engine for the MID600B?
Yes, you can use bigger engine but only need max. 5.5 HP is necessary. It is more
compact and better fuel economy.

Can I use vertical shaft engine for the MID600B?
Yes, with a vertical shaft engine, the pump will be located under the engine and 
will be as good as horizontal shaft engine.

What are the advantages of using the laser starting kit over the plan?
With the laser metal starting kit, it is faster and much easier to built the backhoe
and it looks like a professional did the job, because all critical plates are
already laser cut and there is no machining at all.
 It will cut the building time by more than half the time. 
Your machine will have higher resale value with the kit
and you will be proud of yourself.

How much it cost to built the backhoe MID600 from the plan?
It costs around $3000 US to build the towable backhoe.

How much does it cost to built the backhoe Model 3PH-WP500?
It costs around $1600 US to build the towable backhoe.

  How much does it cost to built the backhoe Model 3PH-MID600?
It costs around $2000 US to build the towable backhoe.

How much does it cost to built the backhoe Model 3PH-PRO800?
It costs around $2500 US to build the towable backhoe.

Can I buy the laser parts separately if I ever need to replace them?
Yes, you can buy any laser parts if you ever need to replaced them.
 

Go Kart Plans FAQ

spindle plates, etc.?
You have to make these plates yourself or we may supply them separately in a

Can we change the tire size & or sprockets?
Yes, but use the method of calculation from the plan.

instead of 15 amp. for the 110 VDC system.

What do the Plans look like & what do they include?
The plans are computer drawn in 3D, and include specification, bill of material,
calculations, electrical schematic system,
electrical wiring system, assembly instruction & how it works.


Where can we buy the parts?
These parts should not be very hard to find, basically you need an engine 6 HP
or more, one 12 volts lawn mower battery, engine pulley, belts, alternator,
voltage regulator, electrical parts, etc...

What are the advantages of building a welder yourself?
Because they are not only welders, they also supply 110 volts electrical current
and work with most electrical tools like electric chain saw, skill saw, drill, grinder,
they all work with DC & AC current.
