Dixie Chopper 2460, When mowing and moving forward (happens when mowing downhill) there is a strong rattling sound from the engine and pump area. I have checked all mounting hardware and nuts and bolts. What could cause this.
Rattling Noise

First remember that noise made by loose metal can travel a long way. Could easily be coming from any where on the unit. Things I would check are, all parts of the belt tensioner assembly both drive and deck, deck suspension system, engine mounts, muffler, engine covers, hydro and axle mounting, etc. If possible have an assistant walk next to the unit while your operating it, or vise versa, as it may be easier to locate source.
Sounds like a Magnum 2460. I would look at the motion idler arm. Those mowers had a propensity for the idler arm to make noise. If that is the issue you can take some kind of pry tool and stick it between the end of arm and the frame and bend it down until it stop making the noise.

The tension arm pivot wears as does the pulley and the spring looses tension over time
All of these will cause a rattle as will a small nick on the belt or a flat spot on the pulley or some crud stuck in one of the drive pulleys

If the bolt on
If it is the tensioner pulley arm we are talking about, first make sure the bolt securing it is tight. As the bearing or bushing wears, slip develops. Cut a section about 6” of fuel line and split it on one side, wrap it around the arm and zip tie it to arm. Viola, your rattle is now gone. Not necessarily a permanent fix, but it works.
