Wiehle Rollers
Here are some adaptations of the Wiehle roller:
Aluminum lessens contact pressure due to weight
difference.
Cast iron increases cutting unit control by increasing
contact pressure.
Wider spacing tends to increase incursion into the
canopy due to increased contact pressure while
disturbing less grass.
Narrower spacing tends to lessen incursion into the
canopy acting more as a full roller.
The end of the roller is designed to allow for a clean
transition.
Tapered or wider transitions are less disruptive to
the turf during cutting unit steer.
Disc (flute or Wiehle) design modifies turf
interaction.
Shouldered Wiehle Rollers
The shouldered Wiehle roller offers the same
ground engaging characteristics as a non-
shouldered Wiehle roller.
Outermost grooves are filled to help minimize
stripping of grass due to cutting unit overlap in warm
season grasses.
Accessories
There is an entire array of accessories available for
reel mower cutting units.
