Securely chock front wheels. Jack up rear. Securely support on axle stands or blocks under rear wheels. Unbolt towing eye to access nut beneath which secures variable speed pulley. Unbolt and remove variable speed pulley. Unbolt and remove idler wheel next to variable speed pulley. Now, slightly more difficult, remove double pulley ( upper drive and lower cutter belt ) from engine drive shaft. Long reach 17/16 ? Socket necesary from engine shaft. Prevent. engine turning (DISCONNECT SPARK PLUG just in case) using bar through hole in lower (cutter) pulley - may need to tap down on lower pulley ( carefully - don't damage pulley ) to release pulley shaft from engine shaft ( this is keyed ). Locate new belt and re-assemble engine pulley. Route both belts and continue to reverse assembly.
Hi there The blade bolt on a yardman dx70 is very easy to remove. if i can remember it is a right hand thread. When i came to remove mine it was very tight so i had to use a long bar to help me unscrew it. Some people tell you to remove the deck but i found it just as easy to lift the mower on its side and prop it up to prevent it falling on you. thanks k Jones
The sensors on the MTD Yard-Man DX70 are typically located in areas that monitor key functions such as the engine, transmission, and safety features. Common sensor locations include the engine block for temperature and oil pressure sensors, as well as near the transmission for speed and gear position sensors. Additionally, safety sensors may be found on the seat to ensure the operator is present when the machine is in operation. For precise locations, it's best to consult the owner's manual or a service guide specific to the model.
