with the Differential Lock engaged (wheels locked together) puts a significant strain on the differential and
related systems.
E. PTO Speed Control Lever: This lever is located at the rear right side of the tractor. It has 3 positions:
540 (RPM), N (neutral), and 1000 (RPM) The 540 RPM speed is the most commonly used; only use the 1000
RPM speed if it is clear that 1,000 RPM (revolutions per minute) is what the attachment requires. When shifting
into a PTO speed from neutral, the clutch should be depressed. The tractor should be in neutral gear and
the
parking brake ON when engaging PTO devices which are designed for stationary use. This mechanical
(rotating) PTO connection can be used to power a variety of attachments (see Attachment section for more
information).
F. 3 Point Hitch: The 3 Point Hitch allows
connection of attachments to the rear of a tractor.
There are three physical points which connect to an
attachment. The 3 Point Hitch also allows raising and
lowering of the attachment through the hydraulic
system. This picture shows a mower attached to the
3-Point Hitch. The mower attachment also requires
PTO power to drive the mower blades.
6) Hydraulic Control Lever: This lever is
immediately behind the Differential Lock Lever. It
controls the height of the 3-Point Hitch system at
the rear of the tractor. It raises (R) or lowers (L)
the 3-Point Hitch by moving the hydraulic lifting
arm (See Attachment section). It has 3 positions R
(raise), N (neutral), and L (lower). After pushing
to R or L the control will automatically return to N
when the attachment has been fully raised or
lowered; you can also manually return the control
to N to stop the attachment at any in-between level.
