I have two problems, I just bought a Toro 724-z a few months ago and I was told it won't fully charge and I would need to charge the battery about once a month. Problem 1) It wont charge at all, I bought a new battery and still the same thing. After I charge it I can use it for about 45min-hour before it dies or if I turn the blades off or turn the mower off I will need to recharge it. any suggestions? Problem 2) After a few week I noticed that the right side after about 30 min would lose some power, Now after about 15 mins on hills it loses more until it would move. I can continue to cut mostly using the left and it will start to have power but not much, I was told to drain the hydraulic fluid and re place it & still no change. Any suggestions? I was given no manuals but have downloaded some. I know I was taken on this so I just need to try to fix it. Thanks for any help.
