AFT 100 Tractor mounted trencher
As you can see ther is no chain, it was used on sports turf the place I got it from had put the chain on another machine it also has a cross conveyor and soil skirts which could be easily removed. I am not sure on max depth but if you fit a new chain it would only be a matter of lengthening the digging boom and scraper sections, to adjust the working depth it also requires some oil pipes and half of the PTO shaft
Laser braket fitted
Make me an offer ???
