John Deere 30-inch Tri-Cycler Mulching Kit

The Tricycler system gets its name from the ability of a John Deere mower to bag, side-discharge, or mulch to meet the three phases of lawn care that are associated with the changing seasons (spring, summer or fall).
The Tricycler mulching attachment allows converting th mower so it can be used to perform the mulching function (grass or leaves) of this system.
The attachment consists of a special mulching blade, a deflector ramp to direct the clippings into the blade for re-cutting, and a discharge closure plate with adjustable baffle.
Operating tips
  • Adjust baffle to the proper opening;.
  • The adjustable baffle can be moved to one of five positions to match conditions using the convenient wing nuts.
    • When mulching grass, the operator should start with the baffle set in the highest position (greatest opening).
    • In drier conditions or when mulching leaves, the baffles can be moved down to reduce the amount of material that is discharged.

Note:The holes in the adjustable baffle are intended for leaf mulching. When mulching dry leaves, the holes will allow some air and leaf particles to escape, reducing blow-out in other areas of the mower. However, when mulching grass, these holes can be expected to plug.

  • Mow when the grass is dry.
  • Observe the 1/3 rule.
    • No more than 1/3 of the grass blade should be cut off at one time; this allows more efficient mulching and will promote the continued good health of the grass. If the desired cut height can't be achieved by cutting off 1/3, or there is clumping of the clippings, it may be required to cut higher. Wait a day then lower the mower and make a second pass.
  • Mow at proper intervals - approximately every 4 to 5 days.
  • Always mow with a sharp blade.


  • Remove Tricycler attachment and install the appropriate medium or high lift blade.


  • Deflector ramp and discharge cover must be removed.
  • Special mulching blade may be used if satisfactory results are achieved. If not, remove and replace with standard blade.

Works perfect
The thing was easy to install, only thing is that I needed to drill out on the deck to fit one of screws perfectly, but not sure if I had not alligned properly. Anyway, nothing a handy person can't fix in a minute. As for performance, it simply does its job.
