Few more bits done today, I'm struggling to find the time, but every now and again alot gets done.
Doesnt look like much, but figuring out how the foot pedal for the hydraulic drive will go is a huge step.
Hydraulic tank. The filler will be on the top. The top plate that the sticky up bit (technical term) is welded to unbolts. Its got about 40 bolts holding it on as it has to seal. Its just so you can get access to the filters in the tank. The 'patches' on the sides and front are where the lines going into and out of the tank will be welded. I welded the thicker steel 'patches' on for a bit more support. It holds a shade over 12 gallons, which should be enough hopefully, thats a bit less that half the total flow rate of the pumps.

The pedal. This is just the rocker part. I'll have a bit coming off the front and back that you press down to move the rocker. It'll be directly connected to the drive valve
