Power Take Off (PTO)

Description

The Power Take-Off (PTO) transfers engine power directly

to mounted or trailed equipment through a splined shaft

(1) at the rear of the tractor.

A PTO flip-up guard (2) is standard equipment. This guard

serves as a support for drive-line shields used with PTO

driven equipment, and provides safety for the operator.

Do not modify the guard.

The PTO system is independent, that is, the PTO may be

engaged or disengaged whether the tractor is moving or

stationary. Rotation of the PTO shaft is not affected by the

main clutch and tractor speed, but is related directly to the

speed of the engine.

GNIL14TR00560AA

1

The system utilizes the standard 6-splines shaft designed

to operate at 540 RPM.

A standard speed of 540 PTO can be obtained an engine

speed of 2575 RPM.

Attaching Power-Take Off (PTO) driven im-

plements

To connect PTO driven implement to the PTO shaft, re-

move the PTO cap (1)and store in the toolbox. Attach the

implement to the PTO shaft (2).

NOTICE: After attaching mounted implement, carefully

raise and lower using Position Control lever and check

clearances and PTO shaft slide range and proper fit.

When attaching trailered implement, ensure the drawbar

is correctly set.

GNIL14TR00515AA

THREE POINT LINKAGE

Three-point linkage

Description

The three-point linkage enables semi-mounted and fully

mounted implements to be connected to the tractor, and

be controlled by the tractor hydraulic system. The three-

point linkage consists of two lower links (1) connected to

the rear axle housing. The rear end of the lower links are

connected to the lower hitch pins on the implement.

The lower links are raised and lowered by means of the lift

rods (2) connected to the lift arms . The right-hand lift rod

is readily adjusted to ease the attachment of implements

and to level the implement after attaching.

GNIL14TR00562AA

1

The top link (3) is connected to a bracket on the hydraulic

lift housing. The rear of the top link should be connected

to the upper hitch pin of a mounted implement. The top

link is also adjustable to aid implement setting.

Adjustable stabilizers (4) are connected to each lower link.

The stabilizers limit side to side movement of the lower

links and attached implement. Adjust stabilizers so that

there is not any interference between the tires and the

lower links.

Most implements can be attached to the tractor as follows:

Position the tractor so that the lower link hitch points are

level with and slightly ahead of the implement hitch pins.

Carefully bring the tractor rearwards to match the trac-

tor and implement hitch points. First attach the left-hand

lower link (1) then by adjusting the levelling box (2) attach

the right-hand lower link (3).

Adjust stabilizers (4) to limit side to side movement of the

lower links and attached implement. Adjust stabilizers so

that there is not any interference with tires and lower links

when moving attached implement side to side.

NOTICE: When attaching mounted or semi mounted im-

plement to the three-point linkage, ensure that there is ad-

equate clearance between the implement and the rear of

the tractor. The clearances in the raised position should

be checked by raising the implement carefully with posi-

tion control lever. With the implement fully raised there

must be at least 100 mm (4 in). clearance between the

implement and the nearest part of the tractor.

Hydraulic draft sensing spring adjustment

When operating in Draft Control, the top link and hydraulic

draft sensing spring transmit draft signals to the control

valve within the hydraulic system. The top link attachment

to the draft sensing spring affects draft signals.

The draft sensing spring bracket contains three holes for

attaching the top link. The top hole (1) is recommended

for light draft loads and light equipment. With the top link in

the top hole, the hydraulic system is more sensitive to draft

signals. Use the middle hole (2) for heavier draft loads

and equipment, and the bottom hole (3) for the heaviest

loads. With the top link in the bottom hole, the hydraulic

system is less sensitive to draft signals.

HYDRAULIC SYSTEM

Hydraulic systems - Operating

Hydraulic Power Lift (HPL)

This is a closed-center hydraulic system, where a hy-

draulic gear pump constantly circulates hydraulic oil

through the hydraulic system. Transmission lubrication

oil is used as the hydraulic oil. The system allows the

operator to select any of the three controls (position

control, draft control, and float control).

GNIL14TR00580AA

1

The hydraulic Power Lift (HPL)system is operated by the

position control lever (1), draft control lever (2), see, 1 and

the response control (3), see 1.

NOTICE: Some mounted or semi-mounted equipment

may interfere with and cause damage to tractor sheet

metal. To avoid damage check for clearance between

tractor and implements.

GNIL14TR00554AA

2

Position control

The position control lever (1) sets the lower position of the

hydraulic lift. Position control is best for fixed-level imple-

ments that operate above the ground, such as mowers,

rakes, and sprayers. Position control keeps the equip-

ment at one position at all times, so it is not recommenced

for any ground-engaging equipment, unless the field is

very flat and the soil is very consistent.

To set the position control, move the draft control lever (2)

to its full forward position. Then set the implement position

lower by moving the position control lever, forward, or set

implement position higher by moving the lever rearward.

When operating in position control, the tractor and imple-

GNIL14TR00580AA

ment become a single unit that reacts to changing terrain

as one piece of equipment. Once you have position con-

trol set, you can raise and lower the attached implement

at the end of each pass.

You can limit the range of manual position lever operation

by moving and tightening the stop (3).

6-11

6 - WORKING OPERATIONS

Draft control

The draft control lever (1) sets the desired depth of the

attached implement. Draft control is best when using im-

plements that operate in the ground, such as plows, har-

rows, or cultivators. The draft loading on the implement

increases and decreases as the working depth or the soil

resistance changes.

To set the draft control, move the position control lever

(2) to the full forward position. Then set the implement

draft depth lower by moving the draft control lever forward,

or set implement draft depth higher by moving the lever

rearward.

Implement depth will be proportional to draft, depending

GNIL14TR00580AA

4

on the soil conditions. With draft control, the lift keeps the

tractive effort steady automatically.

You can limit the range of manual draft lever operation by

moving and tightening the stop (3).

Combined draft and position control

You can use Draft and Position Control together to operate

in Draft Control but prevent the implement from sinking

excessively when soil conditions change. First set the

draft control lever (1) with the position control lever (2)

fully forward. Then move the position control lever back

until the link arms start to rise. The position control lever

sets the lowered position of the hydraulic lift.

Response control

The response control knob (1) varies the speed of drop of

the lower links.

Clockwise rotation -- Decreases speed of drop

Counter-clockwise rotation - Increases speed of drop

NOTICE: To lock implements in transport position when

driving on road, fully raise Position Control lever (2), see

5 and screw in (rotate clockwise) knob (1), see 5.
