I have 2 older Riding Mowers... Both Model 917.255741. Original one, when I have in neutral (6 Speed forward, 1 reverse) I can PUSH IT or PULL IT Around OK.. But The new one REVERSES One Wheel when trying to PUSH it forward (by Hand) as I TRY to Push IT/Move it a bit?? (Strange?) Maybe someone could HELP Me figure Out WHY It does that? Once I had It started, It Drove OK, "DRIVE" Belt Seemed Looser than Normal, But It Drove in all speeds ok. Once Stopped, and Shut off, It seemed that I could MOVE IT Forward or back by hand power.. Put it on Blocks and When TURN The Rear wheel ONE WAY- The Other Wheel goes the Opposite way? But When Running and in GEAR,They Both Go FORWARD...
2nd Question: My First Sears Mower has TWO Blades (38 inch cut).. The newer one has TWO SETS OF BLADES on each side. Was that Standard? Or For MULCHING?, Or Can I Simply use TWO Blades.. instead of those FOUR? Thanks. caryb1999@yahoo.com
