Mowing What is causing my BX2200 mmm to cut like this?

[5.0 Hatch]

This is the 3rd season and i've tried at least 20 times to adjust the deck with no luck. The deck is perfectly level with the gauge wheels about 1/2" from the ground. I'm wondering if there is just too much slack or something is worn to cause it to bounce like that.

I thought it was just that my yard was rough or i was cutting to fast but my neighbors john derre cut it like a dream. Please help

That's really strange. If I'm not mistaken the front of mower should 1/4" lower in the front than the rear.

Try it at different speeds and different cut heights.

Bad spindle maybe

I would check the height adjustment cam. It may be the stop pin is broken off or the cam has come loose and not keeping the deck at the set height.

When you lower the deck does it hit a hard stop or is it bouncing?

On my BX the cam bolt loosened and made it hard to keep the height constant.

Personally, I don't believe the cam has anything to do with it. Either the finger engages the cam or it doesn't. It isn't going to bounce every foot or so to cause the scalping shown in the picture. I would park on the driveway, put a mirror down on the ground and engage the pto to see what the blades are doing.

It's kind of hard to see exactly what's what in the pictures. Stupid question. Are the blades on the right way around? It's not hard to get wrong.

Shouldn't the deck ride independently of the tractor? All my mowers (JD) propel the floating deck along, but dont control the height. The height is set by the deck's front guage wheels and a rear roller. Since more than one blade is digging in in your pictures, I'd surmize that its a deck suspension problem.

The worn or bent spindle theory seems to make the most sense to me, although I'd think it would vibrate like crazy as you mowed with it. Either that or the blades are not tight to the spindle and are wobbling. Have you inspected the blades for looseness or play - engine off, deck disengaged and key in your pocket, of course? They should rotate on the spindle but not wobble back and forth or up and down. Also, have you been lubing the grease points on the mower deck regularly?

Thanks everyone. I've figured it out or at least I hope. The bracket that connects the front of the deck to the tractor has a slightly bent arm. I think what's happening is that the front of the deck is being supported by mostly one link instead of both. With the deck lifted, there is about an inch of up and down movement. I'll attempt to square it up today and report back. I'll also post pictures of the bent arm
