My 42" cut Poulan riding mower was running perfect. I made 3 path cuts. On mine you have to disengage the blades when using reverse. I had to do that and then when I went to engage the blades when in forward gear the mower cut off and now will not crank. Just put new blades on it today.

Poulan is like an MTD. So your Poulan probably has the same safety feature as the Troy built MTD. You likely don’t know that when you start your engine you turn the key about halfway back to the left and press the triangle sign on the dash. Then a light comes on and you can put it in reverse and cut all you want in reverse. They make them to die when you put them in reverse as a safety feature when you are mowing around pets and kids that may get behind you. If you have no worry about running over and causing damage just turn that off as mentioned every time you start your engine.
