JUST A QUICK UPDATE:
Jobs have picked up since our rainy season has died down, so
i’ve had an opportunity to check out a few of the machines on the list.
Bobcat E85: although the specs looked fantastic on paper, it is grossly underpowered once you get into hard soils. It seems to have a decent amount of weight but not enough power or break out force to back it up. The interior feels cheap and the pedals are thin plastic. The demo model we had for a day could not dig deeper than 12’ feet, but in fairness it was really tough clay. We had to bring out a new CAT415F2 with extendahoe to finish the job and that tractor was also working hard. The E85 has some sort of magnetic safety sensor with a rubber bushing and cheap pin that goes through it...anyways, that snapped at some point and disabled the machine. Pretty disappointed overrall, but I’d probably give it another chance.
CAT 308E2: I must admit this machine was pretty impressive. The cab was roomy and did not feel cheap. This machine had the steel tracks with rubber pads which probably gave it some additional stability. It tore through very rocky soil and did not seem to be low on power. I wouldn’t hesitate to get back into this machine again, but I am curious what our maximum depth would be as it maxed out at 10’ when we hit solid rock.
John Deere 85G: the rental we had wasn’t their newest model, it had over 3,000 hours and it showed! I’d like to get into something a little newer to get a better idea of its capabilities. I know Deere has upped their game recently, so I’d like to see whst they’ve done. We ended up doing a shallow excavation on this machine too so I don’t know the actual depth.
Are manufacturers spec’ing the rated depth with the machine flat on its tracks or with the blade behind and down? Im assuming with the tracks flat on the ground and blade in front.
