Hello, This unit comes with one battery that can be recharged as required.
The manual says 1 year - parts,no labor.
Okay I bought the cart and I am using it on my hilly and rocky yard. It does run away from you going downhill with using the transmission only to slow it down, however it will stop if you use the breaks. I needed to adjust they breaks and now it works fine going downhill.
My opinion is it is pretty tall. You might need to raise the height of the mixer up to dump directly into the cart.
Not listed in operation manual.
how does it handale under weight of 1100 lbs does it dump ok.
