Have Dr. F & Brush mower with 15HP Kawasaki engine. It runs well, has limited slip diff, which makes turning difficult, but does render good traction. Beware of cutting thick brush on any slope; I nearly fell forward while mower was climbing up a stalk and when it cut through the deck dropped down and I had to fight being thrown in front of mower deck. Scary as he*l. Otherwise tough machine and works OP to pulp while cutting anything in its path. Suggest turning off fuel petcock when done for the day, and running carb dry to prevent fuel from messing up carb jets, etc. Have had two carbs on mine due to it being run into my pond by wife, glug, glug, glug!! #%&!!! Current carb, replaced one, (pond incident), Dr. tried to rebuild, unsuccessfully, then they covered me on this new carb's install; is now creating 'hunting' at/near idle RPMs. This probably caused by my using ethanol containing fuel and allowing it to sit in the carb when not in frequent use.
I now use ONLY non- ethanol fuel in all my engines on all equipment, except my vehicles. They're on a diet of corn and water!:shocked::confused2:
For real steep slope guy(s): there is no easy solution, except possibly using a hedge trimmer attachment that can articulate, like I have on my Echo split boom weed/brush, chainsaw, power-broom tool. It takes time, but is safest method I know of, and the hedge trimmer attachment cuts and drops the weeds/grasses instead of spreading them all over the place which might help deter further growth in the area too due to vegetation blocking sunlight to new/regrowth.
