Aircraft ground handling tugs

[glennpretorius]

I own a Sling which is hangared with other light aircraft.
The Sling itself is light enough to maneuver by using its custom towbar.
I am looking for a local, south african manufactured motorised tug that can be adapted to also fit other light aircraft. ( with or without spats/wheel pants, tail draggers etc)
There are a few options from overseas manufacturers which are great options however the cost of these tugs and shipping is prohibitive.
Any suggestions out there ....?
