Mower stalls when I engage blades.

Hi. I have a John Deere zero turn mower. It runs great and cuts just fine. However, I just installed the power flow bagging system and now the mower stalls when I attempt to engage the blades. Initially, when I first installed the power flow unit, which is belt driven, it worked but the mower struggled to get the power flow going but it eventually did. Now, just a few days later, the mower can’t get the power flow going. It doesn’t sound like a safety switch issue as the engine doesn’t just cut off, rather, it struggles and it sounds like it wants to go but the engine stalls … any help would be much appreciated!

@msp3017 what model is the mower? Any difference if you unistall the power flow bagging system? I am wondering if this "mower struggled to get the power flow"and " it struggles and it sounds like it wants to go but the engine stalls" is not an engine issue.

Sounds like the installation may have an issue if there were problems with the unit struggling to startup from the get go. I have a four wheel steer JD tractor and it’s design allows the primary drive belt of the deck to be removed easily and then you can turn the actual driven side of the mower deck by hand and see if you feel resistance on the driven side of the deck. If you try this and it feels stiff turning by hand…. you may have found the issue. You will have to dissassemble and find the real issue in your installation though.

Since the engine runs with no load but stalls when a load is applied this would be a fuel starvation problem. Check restriction in fuel line, clogged fuel filter or fuel pump.
