Genuine Toro PowerClear 621 and 721 Snowblower Paddle and Scraper Kit (99-9313, 133-5585 (replaces 108-4884))

Should watch You Tube instalation video, it makes it easier to install

The genuine OEM paddles and scraper bar fit perfect. Very good communication with seller also.

Worked as described

I haven't had a chance to use these yet so it's difficult to rate their durability. What I can tell you is that Bill's Place Outdoor Power Equipment (St. Peters MO.) knows how to ship their products. Fantastic service. I got the new paddles and scraper bar for my Toro single stage snowblower a week earlier than expected. That was a big plus because it turns out that gave me extra time to install these items and we're expecting a huge storm in the area today. The installation is not easy on the paddles because there are a couple of nuts/bolts that are hard to reach and thread properly but that's just the way this Toro was designed. Using a piece of duct tape in an open end wrench to hold the nut or using a needle nose pliers also works. It takes patience but it can be done. The durability depends on the surface you're cleaning........rough concrete = more frequent replacement. Just remember this......if this 74+ guy can do it you should be able to do it too. Amazon's delivery was, as usual, spot on.

Some say not OEM but looks like OEM to me. Reading some reviews, Looks like folks are taking more apart than needed. I just unbolted the ends then the middle, replaced in reverse order then did the other side. The scraper was two bolds and two springs. Easy install and high quality Toro parts. Would definitely buy again.

I had to do some repairs to my blower late winter and only got to use this a small number of times after the replacement of scraper and blade. Because of this I don't have enough field experience with it to give a solid review.The scraper seems sharp, but doesn't appear to be made from very durable plastic. Will have to check on wear next season. These blades were noticeably thinner than the OEM and measurements were taken and posted below.I know at least a few things though:* Original OEM blade thickness being removed 9.0 to 9.5 mm* This product's "Genuine" blade thickness was measured at 7.5 to 7.8 mm* The scraper cut through relatively hard snow with ease.

Removing the paddles was not easy, but installing is much more difficult.First, you need the proper tools. Without them, for example T25 torx and wrench, it cannot be done period. Second, even if you have it, it is very difficult to install. While you are installing the paddles facing the Toro powerclear, on the right hand side is where the engine belt drives the shaft. This side particularly, the gap between the side wall and the paddle mount is very narrow (<0.5"). So you need a needle plier to hold and install the nut back. On top of this, the paddle rubbers are very stiff, so it is difficult to put the bolt into the nut held by a needle plier on the other side. I managed to do this using a stop lock hand clamp. By clamping the paddle to the paddle mount, you don't need to put pressure on the T25 bolt.In summary: you definitely need T25 torx, socket with ratchet, 7/16" wrench, and a stop lock hand clamp would be a tremendous help.

Easy install, a little tedious re-starting the nuts with the right hand screws
