Kubota Tractor L185 L245 L295 Workshop Manual EN_FR – PDF DOWNLOAD
TO THE READER:
The contents of this Workshop Manual for Kubota L-Series Tractors are broken
down into the following categories:
(1) Preliminary disassembly procedures required to disassemble each component
parts.
(2) Disassembly and servicing procedures of tractor and engine components,
along with procedures to locate and eliminate sources of mechanical
breakdowns.
(3) The construction, names and functions of the major components of the
hydraulic and electrical systems, along with their disassembly, check-up,
servicing and troubleshooting.
• The Chapter “Preliminary Disassembly” explains how to separate one block
from the other before disassembling each component part: for example,
how to separate the engine from the clutch housing and the clutch housing
from the transmission case, etc. This chapter should be referred to in order
to find out which block must be taken off to repair, check or service a
given component part.
• The Chapters “Engine”, “Tractor”, “Hydraulic System” and “Electrical
System” give disassembly and servicing procedures in sequence along with
respective reference values.
• The Chapters “Hydraulic System” and “Electrical System” also include
names of parts, explanation on component construction and functions to
give a better understanding of disassembly, checking and servicing.
• The troubleshooting charts are prepared to make it easy to trace the cause
of a misfunction from abnormal conditions. For the convenience of quick
trouble-tracing, servicing and checking jobs, reference pages are given with
the sources of trouble so that you can find a full explanation in the text.
• A list of symbols for fasteners, tools and test instruments is given
on page 12. It will enable you to easily identify all the fasteners, tools and
test instruments referred to in the text with the same symbols.
• The article numbers for Kubota Tractor’s special tools, test instruments and
disassembly bases (tables) are given at the end of each text.
If you have any questions or need more information than is contained in this
manual, please contact to the following address: to your distributor or to
Overseas Service Department of KUBOTA Farm & Industrial Machinery Service,
Ltd.
The Kubota L185, L245, and L295 are small, lightweight tractors that were designed for light-duty agricultural work and landscaping tasks. They are similar in design and share many features, but have some differences in terms of engine power and transmission options.
The Kubota L185 is powered by a 3-cylinder diesel engine that provides 18 horsepower. It has a manual transmission with 6 forward gears and 2 reverse gears. The tractor has a 3-point hitch system that allows for easy attachment of a variety of implements, such as a front-end loader, backhoe, or rotary cutter.
