Extended Product Information

FAQs

Can I use this on a tractor with a 102cm deck?

No, this plug is specifically designed for the 98cm SD (side-discharge) deck series.

Does this plug replace part number 325140105/0?

Yes, this is the current part number for that specific component.

Do I need any tools to install this?

No, the plug is designed for manual, tool-free installation into the side-discharge chute.

How often should I clean the plug?

It is recommended to clean the underside of the deck and the plug after every mowing session to prevent buildup.

Will this work if I have a rear-collection bag system?

This plug is intended for side-discharge tractor decks. Check your manual to see if your specific model supports mulching kits.

Troubleshooting

The mulching plug does not fit securely in the chute.

Verify that your tractor deck size is exactly 98cm. If the deck is a different size, this plug is not compatible.

Poor mulching results with clumps of grass left on the lawn.

Ensure the grass is dry before mowing. If the grass is too tall, raise the cutting height or mow at a slower speed.
