Here is a video of planting potatoes, I used the bolens HT23 and the disk hiller. I was able to drive slow and make a hill with a row in it then we dropped the potatoes in 24" apart and then made 2 passes at full speed to cover the potatoes. It seemed to work great, only had to go through and cover a potato here and there.
Great videos and information!!
In years past I've just made a small furrow with a sweep on my Case 444, then planted the potatoes by hand and covered them by hand. The first year we did that we got about 700 lbs of potatoes (mainly Russets) out of 45 lbs of seed potatoes. Years 2 and 3 didn't do well due to a wet spring and not being able to keep the weeds under control.
This year I did the same thing you did, only used my Mahindra Max 25 with a tool bar bolted to a 3 point trailer mover I bought. I made my own brackets and mounted a couple hiller disks I got for Agri Supply... worked very well..
Potatoes came in spotty on the first planting, but we transplanted the volunteers we found in the furrows and they're doing well.
We planted more rows about 3 weeks later, and they're almost catching up to the first planting... hopefully we can stagger the harvest.
We dug them by hand the first two years--what a chore!! Last year I used a middle buster on my Mahindra... worked pretty good... if I could find the furrow. The Case is narrower than the Mahindra, so I ended up running on the tops of some of the furrows.
This year I swapped out the Industrial type tires and wheels from some Ag tires and wheels. When I get ready to harvest, I plan to use the middle buster again to bring the potatoes to the surface.
I've also worked harder at keeping the weeds under control... I bought a BCS 725 tiller this spring and repowered it with a Chinese 9 hp OHV engine... works like a champ... I till the furrows to get the weed there, and just bought a furrower to help cover the potatoes... worked pretty good, but wasn't wide enough for the furrows made by the Mahindra, still I still had to complete the hilling by hand, but it wasn't as hard.
Anyway, enough of that... thanks for the pictures and the info... I may try a tunnel next year... wonder if it'll keep the deer out of the melons and tomatoes???
