OPTIONAL ACCESSORIES

FIGURE 7

20” Front Rollers

The front roller replace the standard caster wheels and provides a few advantages.
First, this adds additional weight to the front of the mower for more stable tracking which is helpful for rougher yards. It also minimizes uneven cut from low spots and allows the mower to hang over the lawn edges and flower beds for extra close cuts. They are made of hard plated steel and have large sealed ball bearing for long life durability

Back-Lapping Kits

Back-lapping helps improve the cutting action by removing nicks and high spots from the surfaces to create a more consistent contact between the blade and bed knife for an effective scissor cut.
