A hydrostatic tractor that creeps in neutral, or a seat switch that kills the engine whenever you shift your weight, is the fault this Mtd 700 service manual PDF was written to fix. It is Mtd's 360-page factory service manual for outdoor power equipment, part number 770-10579, spanning seven lawn tractor and riding mower series from the 300 to the 900, plus Yard Bug, Auto Drive and zero turn models. Safety interlock wiring diagrams fill a good stretch of the electrical section, backed by troubleshooting charts that trace a no-start to the switch or electric clutch at fault. Transaxle teardown, hydrostatic service, belt routing and deck leveling cover most of what remains. Set the belt guard about 1/8 inch off the belt, and store spare belts below 85°F and 70% humidity. Meanwhile the grass grows every weekend the mower sits. Bookmarked and text-searchable, it's bought once and yours for as long as that tractor runs.
