1 Introduction
JRCO takes pride in its attachments and have designed and engineered quality, commercial built attachments
designed to help you efficiently and effectively be more productive at tasks.
1.1 Application
JRCO front-mount dethatchers are available in a 46 width for the Toro Multi Force standup mower with the 2”
hydraulic lifting receiver.
The Tine Rake Dethatcher is the ultimate spring clean-up tool. Use the rake for the first mowing of the spring to
remove thatch, embedded leaves and debris. The patented tines lift thatch without damaging healthy turfgrass
and at the same time comb matted grass giving the lawn a clean, hand-raked appearance.
After a hot summer, use Tine Rake Dethatcher to surface aerate the soil. This promotes root development and
makes room for thicker turfgrass. Use the dethatcher during seeding operations to rake in seed and accelerate
germination. Finally, use Tine Rake Dethatcher for the last mowing of the fall leaving a picture-perfect, clean
lawn.
Whether you mulch or bag, the Tine Rake Dethatcher can be used throughout the growing season as a tool to
control thatch accumulation and reduce the chance of turf disease.
The Tine Rake Dethatcher quickly attaches to the JRCO mount bar with clevis pins.

3. Secure with 5/8 hitch pin and hairpin
cotter.
4. Insert 3/8 x 5” clevis pin in hole in
between side plates. Secure with
circle cotter. This pin will be used
later, when folding the dethatcher for
transport.
5 Adjustments
1. Adjust the height of the dethatcher with
the rake on level, paved ground.
2. Level the dethatcher by adjusting the
shaft collars on each caster assembly. Use
a 5/32” allen wrench to loosen set screws
in shaft collars and adjust each wheel. The
caster may need to be rotated to locate
the set-screw. The top of the rake deck
should be 9 ½” from the ground.
3. When adjusted properly, the tips of the
tines should be approximately ¾” from a
hard surfaced ground. When the
dethatcher is on turf, the tines will engage
the grass and work back and forth lifting
and flicking dead grass and thatch.
