I use my field Cultivator to prep last years garden for this years planting. I plan to plant potatoes, beans/peas and possibly some corn along the tree side. I cut this field cultivator down to around 4-5 foot to fit behind my tractor better. There are 5 tines I could add more, but 5 do a good job and are relatively easy to pull.
I have read that a Field Cultivator does a much better job loosening your soil for planting than a tiller. Which is because it does not disturb the layering of the soil. Or what is living/dormant in those layers as much as a tiller does. Also it is less likely to kill worms and other beneficial animals living in the soil.
This is the Cad digger my father had built about 15-20 years ago. It’s basically a self propelled backhoe that transforms into a trailer for long distance transport. It does this by moving the front arms to the stowage position, then placing the wheels where the arms were and sliding a hitch into the mainframe under the motor.
In this video I give an overview of the unit and explain some of the modifications I have made over the years to improve and or fix the original design. I also show the unit in action replacing a culvert, and breaking up some badly setup concrete.
See it move itself starting at 2:07 watch it tear up some badly set concrete at 3:11 watch it dig up my driveway to remove the old culvert at 5:38
We made a few small modifications from the original design because of flaws in the original design. Pins were only staked on one side a lot of broken pin housings were replaced with just through pins because of this design flaw. We also reinforced the side to side rams which has fixed the problem of the rams flexing to much. A lot of duck tape has been added to hydro lines where they rub to stop them from getting worn out, this is an ongoing battle. The hydro line runs on this were pretty badly designed but would cost quite a bit to correct so we just keep duck taping them and hope we don’t spring a leak.
The biggest fix was I replaced the 3/8″ metal arms that attach the front ram to the bucket with 1/2″ metal arms. The reason being is I had a pin back out after a keeper pin failed and the arms bent easily under the pressure which caused the hydraulic ram to get bent, “I was able to heat it up and straighten it luckily.” Since I had to replace the arms anyhow I decided to beef them up so they would not bend so easily, I also added some pipe stock in between them to keep them spaced.
