JM
When I got my JD X728SE delivered I discovered it was about 2 qts low on hydraulic fliud, several nuts and bolts were loose and fell off within 5 hrs of use. Come to find out my dealer paid high school kids per unit to uncrate and assembly them.
Its a good idea to check all the fluids when you get any new vehicle. I know someone with a Ranger who decided after using it for about a month and 100 miles who he would check fluids, he found the front hub and rear axle were both under-filled. He was ticked off but the dealer just schrugged it off as nothing to worry about.
