Clear away heavy build-up of grease, oil and dirt, especially
in the engine and under the seat platform areas; minute dust
particle are abrasive to close-tolerance engine and hydraulic
assemblies.
Inspect mower daily for grass clippings and wire or string
tangles. The underside of the mower deck will collect a build-up
of grass clippings and dirt, especially when grass is wet or has
high moisture content. This build-up will harden, restricting
blade and air movement and will probably show a poorer quality
of cutting. Therefore it should be removed routinely.
To do this it will be necessary to raise and block the deck
using jack stands or blocks in the full up position. Scrape the
build-up from underneath.
Some repairs require the assistance of a trained service
mechanic and should not be attempted by unskilled personnel.
Consult your Hustler
® service center when assistance is needed.
