FUSIBLE SCREW
The SVH-1 Subsoiler tiller is equipped with a fusible
safety screw (A).
This bolt will break if the tiller accidentally runs into
rocks, logs, roots, etc.
This protects the Subsoil and the tractor from possible
serious damage.
CAUTION: To avoid accidents, do not attempt to
remove a broken fusible link if the tiller is in a horizontal
position (tip up). With extreme caution, place the tiller
in the vertical (normal) position before replacing the
fusible safety plug.
IMPORTANT: The fusible safety bolt (A) must be
replaced with a grade 5 fusible safety bolt, do not use
any other hardness grade. After replacing the fusible
safety bolt, retighten the rudder bolt (B) according to
the bolt tightening specifications table on page 36.
REPLACEMENT OF THE TIPS
The replaceable scarifier tip (A) on the shanks (Shoe)
allows you to replace it with a new one when a tip has
been damaged, broken or worn.
To replace a tip, drive the pinch pin (B) out from
between the tip and the rudder with a 10 mm (3/8") pin
punch. Do not use a tapered punch.
Remove the damaged tip and install a new tip on the
chisel. Place the pinch bolt through the new tip and
shank.
KEEP THE SUBSOILER AVAILABLE
Thoroughly clean the Subsoiler before storing it.
Protect shanks and scarifying tips from corrosion by
applying a light coat of oil or grease.
Apply a good anti-corrosive when storing the Suboiler
for the next season.
After storage: Clean accumulated dust from moving
parts to prevent abrasion and excessive wear.
Inspect the Subsoiler thoroughly. Check for loose parts
and adjust if necessary.
