I am using a back blade angled and tilted and have to move the waste across the road with the back blade and FEL. An excavator with a tilt bucket would be neater. 10 foot road is 1/2 mile up and across a very steep hill. Ditches need cleaning yearly.
I picked up a 800mm (31 inch) smooth bucket for road ditching work with my Typhon Terror X 1-ton. Used it to clean out about 200ft of ditch last week. Worked fine and did not require any tilting mechanism. Since it was just cleaning and not really breaking new ground there was not much stress on it. For digging a new ditch I would want to use the smaller tooth bucket and operate like I was trenching.
My technique was to run along the road and dig from the side as I went, rotating and dumping into a skid steer bucket so as not to put debris on the road. Would have gone quicker with another person to operate the skid steer or if I had a dump trailer.
Ok, thanks but I was looking for info on what brands of 15 hp excavators you were considering BUT bottom line still no since a 15 hp machine does not weight enough to lift a ditching bucket of any size much less a loaded ditching bucket. Add the assembly for tilt for approx another 50 pounds. My 30" ditching bucket weighs 355 Lbs empty, add another 50 Lbs for tilt and your over 400 Lbs empty. The 30" bucket holds 0.15 struck cubic yards. Swinging this at 12 feet out is enough to unsettle the 10K+ pound M59.
The Kubota KX018 at 16 hp and 3748 to 3968 lbs is too light to handle what your asking to do.
