White MTD Mower Blade Engagement Problem

Hi folks -

Hope you're all well.

I'm having an issue with my White MTD mower (model # 13a5472f190). When I push the lever down to engage the blade, it works fine and the blade runs smoothly. It also runs smoothly as I drive on the concrete.

But as soon as I put the mower in the grass, the blades aren't engaged and no grass is cut.

Any ideas on what could be causing this? I'm at a loss.

Thanks!

Sounds like the blade belt is slipping. Could be a bad belt, or it might have slipped off an idler pulley. Could be a problem with the tensioner. Could even be loose blades.

With the engine off, engage the blades and then try to turn a blade by hand (with gloves on); see what slips.

That's what's crazy - is everything runs exactly how it should until the blades are engaged in grass - then they don't turn. So when I engage the blades without the mower on - everything works perfect. No slipping, bad belts, etc. Very odd.

When you try turning the blades by hand with the mower off, did you lower the deck to mowing position or was it all the way up?

Have someone else operate the blade engagement while you watch from the side to see what keeps moving and what stops moving.

I agree that it sounds like poor belt tension.

Have you had the deck off for any reason?

Does the deck keep lowering as you lower the handle to a shorter cutting height?

You may have lost a spring or have things bound up on the deck lift...this is an old MTD style PTO, the blade engages as you lower the deck...???


Just needs a bigger hammer

Hi BFHFixiit -

Yep - the deck lowers as the lever lowers. But the deck hasn't been taken off for any reason. But yes - the blades engage as the lever is lowered.

There should be a spring connected to a hook under the transmission on one side and it goes up to a bar on the deck, pulling the deck back towards the rear of the mower. This spring is what makes your belt tight. If this spring broke and fell off, the belt would not tighten properly and cause the problem you are describing.
