Landowner here with acreage to maintain looking to buy a 6-7 ton mini to complement a 100hp tractor. 50-75% of mini’s utility will be mowing pond banks and slopes not accessible with tractor mowers. I don’t anticipate a lot of digging. Only other experience I have in "heavy" equipment, besides the tractor, is running a brush mower on a rental 95hp CTL. I have none in excavators and the few rental outfits in my area that rent them do not rent mowers.
My question has to do with how the hydraulic pumps share the workload and if some manufacturers prioritize one part of the system over another. Example, can you run a rotary/flail head rated at, say, 16-25 gpm at the same time as moving on the tracks and slewing AND dipper/bucket movement without one or more of those actions suffering? I’ve watched some YT mowing videos where the machine (<4-5 ton) was squealing with the mower blade slowing noticeably when the machine was moving. Is this typical of excavators in general or just the lower hp machines? Do some machines have pumps dedicated to certain functions or larger pumps overall to minimize the hit? Machine literature gives you very little information other than flow and pressure. Any manufacturers you’d recommend for my application? Thanks in advance for any replies.
