18” CHIPPER MACHINE MAINTENANCE
47
HITCH
• Make sure the bolts on the chipper hitch
are tightened. If not, tighten to the
specified torque for the bolts size. Also,
make sure the hitch bolts on the tow
vehicle are tightened properly.
• Check the bolts and nuts for wear. If
bolt or nut threads are chipped or worn
down, or if the bolts and nuts won’t stay
tight after tightening them, the bolts and
nuts need to be replaced. Check the bolt
holes for wear also. If the holes are
elongated or distorted, the hitch and/or
the hitch plate will need to be replaced.
• Keep the Pintle ring on the chipper
greased. This will keep the wear
between the two metal surfaces down to
a minimum and will make your hitch last
longer.
• If the Pintle ring is worn and does not fit
the hitch on the tow vehicle properly,
replace it as soon as possible. The loose
fit between the two surfaces may cause
the chipper to swerve in traffic and
possibly even come uncoupled from the
tow vehicle. Also check the hitch on the
tow vehicle for wear for the same
reasons.
TONGUE EXTENSION
(OPTIONAL)
• Check all bolts and nuts on the tongue
extension, if equipped. Replace any
bolts and nuts that have worn, chipped or
missing threads or that won’t stay
tightened.
• Check holes in the tongue extension
mounting plate and on the machine
tongue mounting plate. Make sure the
holes are round and not distorted. If
holes are distorted replace the mounting
plates as soon as possible.
