In this review of the 121-0751 Spindle Assembly 2 pack, the bottom line is simple: this is a practical replacement for owners of Toro Time Cutter and compatible Exmark riding mowers who need a reliable, ready-to-install spindle set. The reviewer found the assemblies offer a straightforward fit for a range of 42' and 50' decks and appreciate that the package includes nuts, mounting bolts and protective sleeves so there is less searching for hardware.

Key Features

• Direct replacement compatibility: Matches several Toro and Exmark part numbers so buyers can replace worn spindles without complex part hunting.
• Complete hardware kit: Each pack includes top nuts, mounting bolts and black thread sleeves so installation is simpler and you do not need to source extra parts.
• Aluminum alloy construction: The spindle housings are made from corrosion resistant alloy, which helps them hold up under wet grass and seasonal storage.
• Standard mounting size: With a 5-9/16' height and 5-1/2' mounting hole distance, the spindles fit the specified Time Cutter deck layouts for a straightforward swap.
• Two spindles per pack: The 2 pack suits replacing both sides of a deck or keeping a spare on hand for quicker future repairs.

Who It's For

This spindle assembly is best for owners of Toro Time Cutter SS and related Zero Turn models with 42' or 50' decks, and for technicians who prefer a replacement that includes mounting hardware for a faster repair. It is particularly suited to those who recognize part numbers such as 117-0751, 117-7267, 117-7268, 117-7439 or 121-0751 and want a compatible aftermarket option.

Customers who need OEM warranty replacement or who require a spindle with confirmed factory markings for dealer service may want to verify fitment with their dealer first; this product is presented as a compatible aftermarket assembly rather than an OEM-branded unit.
