I been looking at ditch witches. Local to oklahoma ( now they sold out) bigger the machine the better for us I believe?? Least a 750 up.... I landscape, move material, trees, trench for irrigation, grade and sod primarily. Pallets of mulch and every now and then maybe some pavers... size isnt to big of an issie8 as I can get into most backyard as long as it's not over 48". I've rented many Bobcats my 55 and 85. I feel even the 85 is somewhat underpowered at times.... I hate the small bucket they come with. They are to tall and you cant see your cutting edge.... so is bigger better?
