HYDRAULICS

Do not use your hand to check for hydraulic oil leaks. Use a
piece of cardboard instead.
Hydraulic fluid escaping under pressure can penetrate the skin
causing serious injury. If skin penetration occurs, seek
medical attention immediately.
Relieve all pressure from hydraulic system before
disconnecting hoses.
During your daily inspection repair all leaks before they create a
major problem. Relieve all pressure before working on, or
disconnecting the line in the hydraulic system.
The hydraulic system on the TD92 mower is a simple cylinder
system used to raise and lower the cutting decks into position.
Each cylinder is equipped with a .032 diameter restrictor orifice in
the rod-end elbow adapter to throttle the speed of travel.
When reconnecting to the tractor, be sure that both connector ends
are clean. Dirt in the hydraulic system can block the orifice in the
line throttle valve or cause premature wear & failure of hydraulic
components on the mower or tractor.

SUPPORTING MACHINE FOR SERVICE

(2) Points are available to lift the mower off of the ground for
servicing the transport tires / wheels / bearings at the main frame
rail between the transport tire and deck corner pin support plate (as
shown in the accompanying illustration.) Use a bottle or service
jack to raise the wheel from the ground and place a wooden block
or other suitable support under the rectangular tube.
Do not support the machine on cinder blocks, hollow tiles or
other members that may fail under continuous load.
Never perform service on a machine that is supported solely
by a jack. Always ensure proper blocking is placed to support
load during service.
Transport tires must be changed with the wings in the raised
position. Ensure the machine is on a flat, level surface and the
wing locks are fully engaged before attempting to lift the
machine.
