Replacement New Old Stock OEM Rotary Cutter gearbox for WAC "The International Line" IM702 rotary cutters with 20 spline input shaft gearboxes.  These gearboxes will have a square housing with 4 bolt mounting with a 1:1.46 speed up gear ratio and mounting holes 8" on center, a 1-3/4" X 20 spline input shaft and a 1.97" X 15 tapered spline output shaft. The center line of the input shaft is 9-3/16" above the bottom of the gearbox mounting flange to allow additional PTO clearance when raising the deck for transport. There is a gearbox mounting bolt hole directly under the input shaft and each hole is 90 degrees apart. The gear ratio of these gearboxes correctly match the original boxes on your mower.
