Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
Are you certain that the belt is routed properly? This could explain the lack of blade speed if the belt is not routed properly with the proper tension on it.
Belt configuration is pretty straight forward but I have included a diagram of the way the belt should be routed.
Are you using an original equipment belt or an aftermarket belt as a replacement? If aftermarket it could be that the belt is slightly too long which would cause the problem as well.
If the belt is routed correctly the only other thing that could cause a problem would be if there is excess grass built up under the mower deck or a pulley or deck spindle is not turning freely as it should.
Have you checked the pulleys and spindles to make sure that they are all turning freely?
