It took me 1 hour to learn the controls well
enough to be fairly proficient at digging a full
bucket and getting that dumped where I wanted it.
They work fine, the biggest issue is sizing the machine to the work to be done (in my case) then operating it well was the number two issue.
I did some planning ahead homework and downloaded the manual for the machine I rented (245.00 for a day).
After three hours of operating the mini trackhoe I finally got to where I could use the bucket to dig, dump and rake with it, using the blade was around another 20 minutes of learning curve.
All in all I think the day rent was worth it since I am sure I will need to rent this thing at least two more times and the cost is way lower than hiring one to do the work for me.
Besides the satisfaction I get from doing the work myself.
