The FR-25 front roller
replaces the caster bar and casters on your 25” Cal Trimmer mower and there
are some nice benefits. It adds a little weight to the front of the mower
which is helpful for rougher yards. It makes the blade cut at the highest
contour of the yard to help prevent scalping and allows you to cut over the
top of edges.
It also can help provide some striping effect as it’s used over time.The
height adjustment process is the same as the original caster wheels however
the actual cutting heights will be slightly lower by 1/8″ – 3/16″.
Back-lapping does not replace the potential need to grind the reel and bed
knife, especially if there are dents or other areas of damaged edges. However,
if the edges are in good shape and you want to help lighten and smooth the bed
knife to reel contact, this process is the best way. It requires some patience
but good instructions are included. The kit also includes a sprocket adapter,
a 10 ounce container of #80 back lapping compound, and a durable paint brush.
To summarize, back-lapping seats the blade and bedknife surfaces as the blades
are turned backwards and applying grinding compound. During the process
additional adjusting may be needed, but the end goal is to be able to shear
paper across the entire width with smooth and light contact.
