Toro Genuine Spindle Asm 121-0751 supersedes to 139-3214

Did not come with bolts

Correct part was delivered pretty quick, considering I ordered it on a Sunday afternoon. However, I had to call the store before they closed on Monday to make sure it had shipped and decide if I was going to drive 70 miles, through Nashville traffic, to pick it up if it hadn't. Long story short, it hadn't shipped but they shipped it Tuesday and it was delivered Wednesday. Customer support and shipping department was very friendly and took care of everything to get the part to me as fast as they could.

They fit like a glove, I recommend ordering the bolts !

Should have new bolts included. Would be nice if they would make ones with grease fittings.

Suffice to say that I got this replacement last year when my first original pulley blew at the beginning of the season (the mower is 6 years old). Then, last week the bearings in the 2nd (original) pulley blew (I hit a nasty rock that shattered the spindle bearings and the blades), so I just bought the same part as a replacement for pulley #2.
In all fairness, I only gave it a 4 in quality since it's still in its first season. But after use in green New Jersey, the bearings on the first replacement still are tight as a drum. the thing costs half the price of most other vendors.
The only problem is that part 121-0751 looks like it's only the spindle housing (at least in my parts list from Toro), but this is the assembly that includes both bearings and the spacers. It does NOT include the spindle, but my original spindle was fine. The entire spindle with bearings, spacer, and spindle is also available from another vendor.
Enough said. Thanks SLE!
