FREE SHIPPING! This sale is for one BRAND NEW REPLACEMENT belt. This is an exact fit belt made to the exact OEM (original equipment manufacturer) specifications. This is not a "will fit" belt! You will see several listings for this belt online and please compare apples to apples. Several other sellers copy my listings word for word on description and then sell you an inferior cheaper belt so be careful. This is not some industrial or poly belt that will work on your mower but a belt made for your mower! If you want the cheapest belt (I KNOW IT IS TEMPTING) you can find we have that too, but if you want the belt that will stand up to the application you need this is it! Save yourself time and money in the long run and do it right the first time! Your belt WILL HAVE THE part number on the belt and this is the actual belt pictured and not a generic photo! Replaces: WOODS 18990 5/8" x 169.1" Made with kevlar wrapped double banded Woods FINISHING MOWER: RM990 Woods FINISHING MOWER: RM990-3 DISCLAIMER: We list model numbers & part numbers for your reference. NOTE that you may have the same model with a different deck or serial number or configuration. We list the EXACT size of the belt so if you are unsure measure yours. Please do not tell us we sent you the wrong belt when we send you the exact dimension belt we have listed. It is your responsibility to know what you need to order and all we can do is ship what you order. Thank you! Please keep in mind that there are multiple factors that may cause belts to fail. If you don't fix the problem a new belt (from me or anyone else) will NOT function properly. If you are shredding belts, burning the sides, over stretching or they keep popping off...these are not belt problems but something on the mower. We stock what we sell! No drop shipping here and yes it is available. We always ship within 1 business day!
