Thanks Grumpy, input appreciated. I did consider the option of having a wheel, or in fact two, at the front. The issue I had to weigh up was do I keep it as simple as possible with like you said the shortest possible drawbar, or do I put wheels at the front which would inturn require another pivot point in the drawbar, in the horizontal plane above the front wheel mount to allow for undulations. I also considered a king pin steering type design as well. However in the end I went with the KISS principle, (Keep It Simple, Stupid!), hahaha.
As for the tow points, Yes, the slasher is of the fixed pin type hitch, and the towbar boom does have a single eye tow point at one end. Hence the reason for having it removeable so it be utilised on either side, and yes, the ride on does have a tow point in the centre for the very reason you suggested, (although I also have a 50mm tow ball for it too). When in this position, the towbar boom can be slid in and located in the centre position, so as to eliminate any protrusion on either side.
When in this position, the ride on cutting deck is the widest part of the whole configuration. This allows for initial clockwise travel around a particular area, then travelling anticlockwise with the slasher trailing to the left leaving an even spread of clippings over the mowed area, or it is possible to begin in the centre of an area, with the slasher trailing to the right, and clear the mowed area of the clippings.
The ride on and slasher combined give a total 52 inch cut.
