Product Description

?

This shield-trailing is designed for use with Toro lawn mowers. It is an authentic item that is supplied directly from the original equipment manufacturer. The component is secured to the mower's deck to prevent the grass from shooting out. It is an identical replacement for a damaged or a missing shield-trailing that was installed on a new unit. One durable plastic part is included. Check the owners manual for your model for the correct application. Replacing it is a simple task that should only require a screwdriver to remove and replace the screws that hold the shield-trailing to the deck.

Much easier to repair if you work with the mower deck on a workbench up where you can more easily get at both top and bottom of deck. Remove rear wheels and handle assembly. Remove bolts holding rear baffle. Install new baffle and reassemble. Mower working like new!
Then remove the blade bolt, blade support and the old blade. The n install the new blade, the blade support and screw in the blade bolt.

To replace the underside baffle, I had to remove the rear wheels, and all the brackets that held the wheels and the adjustable mower-height features.
It took me an hour to figure out that the first thing you need to do is to take off the push bars. The rest of the repair went swiftly after that.

Had to remove handle, both rear wheels, and height adjustments. The only problem I had was not taking enough pictures with my phone when taking off parts. The new parts from e replacement went on easily. It was remembering the order of disassembly to reassembly of my old parts. Take step by step pictures when taking apart your mower. Aga in the parts from eReplacement Parts went on easily. Will order from you guys again in the near future. I even saved your website to my homepage.
