CHAPTER III - ATTACHMENTS AND ACCESSORIES
1. Overview of Attachments
It is unlikely that you bought the Jinma tractor so that you could ride around on it. You intended to do some
work and doing that work requires using attachments which connect to the tractor and run off of the power
provided by the tractor engine. The following two sections describe the tractor’s PTO system and the Hydraulic
system and generally how they work with attachments.
There are so many attachments and accessories available to work with your tractor that it would not be feasible
to describe how to operate them all. This manual will use a generalized front-end loader attachment and a
generalized mower attachment as examples of how attachments are operated. Sub-section 4 below provides a
list and short description of many available attachments. You should get and follow the specific operating
instructions for each attachment you use with your tractor.
2. Operation of the Hydraulic System and a Front-End Loader
The tractor has a hydraulic system powered by the motor
to create a pressurized system which is used to provide
power (hydraulic pressure) to operate attachments. The
hydraulic system consists of a pump operating off the
engine, a reservoir of hydraulic fluid for the pump to
pump, and hoses to deliver the pressurized hydraulic fluid
to the front and rear of the tractor where implements
would be attached.
Pressurized hydraulic fluid goes into the attachment through one
hose and the fluid returns to the hydraulic reservoir through the
second hose. Both hoses must be connected correctly for the
system to work. The hoses have “Quick Connects” to retain the
hydraulic fluid in the hoses. When no attachment is in place, the
front hydraulic hoses are to be connected to themselves to allow
fluid to move, ensure no damage to the hydraulic pump, and assure
dirt does not enter the system. Because the Quick Connects are
oriented in opposite directions, the attachment only connects one
way.
