Although the W182 is still available, it is recommended that all W182 Chutes be replaced with L127-M Chutes on machines after Serial Number 1980892. However, the L127-M Chute cannot be utilized on machines before Serial Number 1990892 due to contact with the rear swivel wheels.

Machines before Serial Number 1400592 do not utilize the T112 & T113 Rebuildable Pivot Pins or the W182 or L127-M Grass Chutes. Pivot Pins and Grass Chutes are integral with the Deck Weldments.
