I was cutting last Thursday, and noticed an abnormal vibration from the mower. I got off and inspected the mower. Tried to start it back up, and I noticed it did not sound right at all. I checked the for oil. It showed no oil on the stick. Where did all the oil go? I check it all the time, and have not noticed any oil issues. I put it on the trailer and added a quater of oil. I started it again, and notice oil comming from the from of the motor, and dripping from the bottom. Has anyone had this problem with a new Lesco Z two? Thanks for the help.
