That looks very interesting... there is something very similar near here - the same type (if not identical) loader system but no cab. I've been meaning to try to get some photographs but it's on private Shark and is only really visible from a main road. I've not been able to see well enough but I presume that the driving position is also rotated 180 degrees.
I drove a ACE Bulloader in the very early 1960's. It was based on a Power Major with a Manual Transmission. The Brockhouse version was very expensive. It was okay loading from a loose stockpile, but very poor if you had to dig a bit hard. Very difficult to balance the bucket and keep weight on the Drive Wheels at the same time. The Tilta Crowd was just a fancy name for the bucket action.
I thought "Tilta Crowd" was just a fancy name for a self leveling bucket, which, from the photos, the machine seems to have. Actually, someone posted for information on this on the Yesterdays Tractors site and I brought it here because I thought it would get a much better responds, and also because I thought it was Cool. Dandy Dave!
