Repairing cracked frame on Grimme Varitron 270 potato harvester

First up is some footage from Emley moor tractor pulling. The first 2 pulls are me with my Leyland that I built back up in last weeks video. Next is Rob with his 6 cylinder Fordson major, he was having a bit of bother with his hitch being set too high so he was struggling to keep the front end down, then its Jason with his Leyland 285, I think his kill flap was half shut so it wasn’t boosting up properly. Next is Ben with his twin turbo Perkins V8 powered Ford 8210, and last is James with his 6 cylinder Fordson Major. There were 33 tractor pullers in total but I only recorded a few.

To the job in hand,  the customer noticed during the machines annual service that the tank frame was starting to crack. They only plan on keeping the machine for one more harvest so wanted me to do a repair to see them through.  
I cut a section out on the frame so I could access the damaged area due to having no access from the other side, I used the die grinder to Vee out the crack the best I could and rewelded. I rewelded the square back in again, drew/cnc plasma cut out a new plate to brace over the area and welded on. The repair should way outlast the original design.

Hope you enjoyed the video.
Thanks for watching.
