We rented a bark blower for a 40+ yard mulch job. The whole idea was to save time so we could get it shot in one day. First I picked the unit up and the wiring was all frigged up so I/we had to fix it before I can mover it. Next, we get the unit to where it needs to go start it up, ten minutes into the job it gets jammed, then jammed again, and again. This thing jammed 8 times in 5 hrs. Needless to say it cost me time over saving me time. Then the thing started shutting down every 30 minutes and wouldnt start for about 20 minutes. I put aprox. 6-7hrs on it and I bet 3-4 hours were from us trying to fix all of the problems this thing came with! If it would have ran right it definetely would have saved time and when it was working right the final out come was a nice even finish. One thing I was disappointed with (even when it was running right) was the velosity the mulch came out with. It would blow a 3 foot ring in the bed down to the dirt throwing mulch everywhere, maybe a larger diameter hose would help I dont know. But for 600 bucks a day rental fee I was not happy! The salesman said after calling him he's not charging me and would give me my check back but that does me no good now. But all in all I've learned these things have a purpose but for the retail price of 25k NOT WORTH IT imo!
