JD 5225, 5325, 5425, 5525, 5625 PTO

Reversing 540/1000 RPM PTO Stub Shaft

Power Take-Off stub shaft has six splines for operating 540-rpm implements and 21 splines for 1000-rpm implements. A flattened area on the stub shaft facilitates snap ring removal and installation.

- Align snap ring ends with access flat. Remove snap ring and pull out stub shaft.
- Clean stub shaft thoroughly and coat with grease. Be sure end bore is clean when installing shaft for 1000-rpm operation.
- Turn stub shaft end-for-end and insert in Power Take-Off housing until snap ring groove is visible.
- Install snap ring. Move shift lever to agree with stub shaft position.

Attaching PTO (Driven Implement)

- Turn key to STOP position to shut off engine.
- Put drawbar in extended position. If implement will be connected to 3-point hitch, be sure drawbar will not interfere. Fully retract drawbar or remove it if necessary. Install drawbar lock pin.
- Attach implement to John Deere 5225, 5325, 5425, 5525, 5625 tractor (drawbar or 3-point hitch) before connecting Power Take-Off driveline. Raise hitch to full-up (transport) position if it is not to be used.
- Rotate PTO shield up for clearance. With engine off, turn PTO shaft by hand to line up splines. Connect driveline to PTO shaft. Pull out on shaft to be sure driveline is locked to PTO shaft. Return Power Take-Off shield to down position.
- Check that all shields are in place and in good condition. Never operate PTO unless master shield is properly installed. WITH ENGINE STOPPED, check integral shields on driveline by making sure they rotate freely on shaft. Lubricate or repair as necessary. Check for interference.

Selecting Correct PTO Speeds

540/540E Operation

- For standard 540 PTO operation (load requiring full engine power), pull lever back to 540 position.
- For economical PTO operation (lighter load), push lever forward to 540E position. In economical mode, engine is run at lower rpm to conserve fuel and reduce overall operating noise while still turning PTO shaft at 540 rpm.
- With PTO shift lever in 540E position, engine fast idle speed is limited to 1700 rpm.
- Same shift lever design is used for both 540/540E PTO and 540/1000 PTO.

540/1000 Operation

- Power Take-Off conversion kits are available for most tractors. For 540 rpm PTO operation pull lever back to 540 position.
- When PTO stub shaft is installed for 540 rpm implement, a mechanical interlock prevents shifting from 540 rpm to 1000 rpm setting.
- Stub shaft must be reversed from 540 to 1000 rpm position before moving shift lever to 1000 rpm position.
- For 1000 rpm PTO operation, push lever forward to 1000 position.

Operating JD 5225, 5325, 5425, 5525, 5625 Tractor PTO

Engine will not start if PTO lever is engaged. If equipped with EH PTO switch, engine will start with switch up (engaged), but PTO shaft will not rotate until switch is reset.

Depress clutch pedal, start engine and push hand throttle lever forward until tachometer indicates PTO rated speed: 540E - 1700 RPM / 540 - 2400 RPM (full power) / 1000 - 2400 RPM (full power). When in 540E position, engine speed is mechanically limited to a maximum of 1700 rpm. 540E operation will not engage if engine speed is above 1700 rpm. Both 540 rpm and 1000 rpm PTOs operate at same engine speed: 2400 rpm. PTO is engaged or disengaged without depressing clutch pedal.

Engage Power Take-Off

- Lever Operated: Move control lever inward and forward to engage PTO.
- EH Switch Operated: Lift switch knob up to "I" position to engage PTO.
- PTO indicator will light when PTO is engaged.
- A warning alarm will sound if operator leaves seat with PTO engaged.

If engine is stopped while PTO is engaged: 1) Lever Operated PTO - Disengage PTO, restart engine and engage PTO. 2) EH Switch Operated PTO - Restart engine, depress and lift switch knob to reset and engage PTO.

Disengage Power Take-Off

- Lever Operated: Pull lever back to latch stop position to disengage PTO.
- Lever latch stop prevents accidental engagement of the PTO.
- EH Switch Operated (if equipped):Push switch knob down to "O" position to disengage PTO.
- PTO brake automatically engages when PTO is disengaged.

Adjusting 540/540E PTO Lever and Linkage

- Remove spring locking pin from upper control cable. Disconnect yoke from arm.
- Rotate arm to the rear position (clockwise). Move 540/540E PTO lever to the forward position.
- Loosen jam nut from yoke. Adjust yoke until spring locking pin aligns with hole in yoke and arm. Install spring locking pin and tighten jam nut to yoke.
- Start engine and move throttle lever until 1700 rpm is indicated on tachometer. Do not move throttle lever after 1700 rpm is reached.
- Shut engine off with throttle lever positioned at 1700 rpm. Make sure throttle linkage at fuel injection pump does not move during the next step.
- Slowly move the 540/540E control lever fully forward. Make sure throttle linkage does not move forward during this step.
- If linkage moves forward, loosen jam nut and turn adjustment nut counterclockwise until a gap of 6 mm (0.25 in.) is between adjustment nut and plate.
- Loosen jam nut and turn adjustment nut until seated against plate.
- Hold adjustment nut using a wrench, and tighten jam nut.

5225, 5325, 5425, 5525, 5625 John Deere Hitch

Using Mechanical Rockshaft Position Control

Use position control lever to control hitch movement and depth:

Transport - For transport of implements and end of field turn-around, pull control lever fully rearward for both load and non-load sensing usage.

Constant Depth - For constant depth of implements on level terrain and for non-ground engaging implements such as spreaders or sprayers, put position control lever at desired depth. Operate implement for a few minutes to determine proper depth or height. Lift tab and slide stop against position control lever. Turn tab to tighten and press down to lock stop in place. Rockshaft will return to the same position each time control lever contacts the stop.

Float - For float operation for implements with skids or depth gauge wheels designed to carry full implement weight, push both position and draft control levers all the way forward, so implement can follow ground contour. Lift links can be adjusted for lateral float.

Using Mechanical Draft Control

The rockshaft is equipped with variable draft control system:

- Operating with a fully mounted implement in hill and swale terrain, the implement will rise and lower to follow the ground contours while maintaining a nearly constant depth.
- Operating in varying soil conditions, the implement is raised slightly to get through tough spots so you do not have to shift to a lower gear.

Change draft sensitivity ranges by repositioning the center link.

For draft load sensing operation:

- Pull control lever to its fully rearward position and push the draft control lever to the fully forward (least draft) position.
- With John Deere 5225, 5325, 5425, 5525, 5625 tractor moving, push control lever forward to set implement operating depth.
- Set position control lever stop. The operating depth set up will prevent the rockshaft from lowering all the way when the tractor begins to slip.
- Pull draft sensing lever rearward until desired draft sensing sensitivity is obtained.
- To slightly raise implement (for getting through slippery spots in a field), push control lever past the draft control setting.
- Pull control lever fully rearward to raise the hitch at the end of the field.

Using EH External Raise and Lower Switches

When using the fender mounted switches, the rockshaft raises and lowers at a slower rate, and the height and depth settings are ignored. Fender switches are disabled when hitch is in transport position.

Press and hold switch to move rockshaft: RAISE implement with top switch / LOWER implement with bottom switch.

Once either switch is activated, the rockshaft is prevented from moving accidentally.

To reactivate the rockshaft, return to the operator station:

- Move hitch control lever to position that corresponds to position of the draft links.
- Actuate raise/lower switch.

Adjusting Raise Height - Control the implement height with knob: For minimum height, turn COUNTERCLOCKWISE. For maximum height, turn CLOCKWISE.

Adjusting Rate-of Drop

A - Hitch Control Lever, B - Raise/Lower Switch, C - Height-Limit Control, D - Rate-of-Drop Control Knob, E - Depth Stop Wheel, F - Hitch Control Lever, G - Load/Depth Control Knob

Fully lowering implement should take at least 2 seconds.

Control the speed the rockshaft and mounted implement lowers with knob (D):

- To slow rate-of-drop, turn knob COUNTERCLOCKWISE.
- For faster rate-of-drop, turn knob CLOCKWISE.

Adjusting Depth Stop

- Push down and rotate wheel (E) to set stop to the desired working depth.
- Push control lever (F) forward to contact the stop to return the implement to the indicated working depth.
- To lower hitch below the preset depth, lift and push the control lever past the stop.

Using Float Control

- For rockshaft-controlled implements with a gauge wheel, implements can move freely up and down to follow ground contours independent of the JD 5225, 5325, 5425, 5525, 5625 tractor.
- Turn control knob (G) to position control detent and push hitch control lever (F) as far forward as it will go.
- Adjust lift links for lateral float.

Adjusting Load/Depth EH Controls

Hitch has two operating modes: Detent control position / Draft control positions.

Position Control Setting - With load/depth knob in detent control position, the implement is held at the selected position.

Using Draft Control

Turn load/depth knob to one of five draft settings, to control depth and load, depending on implement and field or soil conditions:

- Turn COUNTERCLOCKWISE to reduce draft response.
- Turn CLOCKWISE to increase draft response.

With the control turned to a higher number, the implement is raised as resistance (soil density) increases and lowered as resistance decreases; typical settings.

Integral Ripper/Subsoiler - 1-3
Integral Chisel Plow - 2-4
Semi-Integral Moldboard Plow - 2-4
Integral Moldboard Plow - 3-5
Integral Field Cultivator - 4-5

Preparing Implement

When attaching Category I implements to the 5225, 5325, 5425, 5525, 5625 John Deere tractor, sway bars may need adjustment to prevent binding and limiting full raise of the hitch. Category I, 3-Point Hitch is narrower and is used for smaller implements than Category II implements. Category II implements should have the top hole of the implement mast located 483 mm (19 in.) above the lower pins. Drill another hole in top mast or extend top mast if necessary.

Converting Category II Hitch to Category I

Center link end is sized for Category II implement attaching pin. If Category I implements are to be used, the Category II hitch can be converted as follows: Insert reducer bushing in center link end. Smaller implement mast pin is also needed when bushing is installed. Rotate balls in draft link ends to fit over implement pins.

Positioning Center Link

The center link attaching bracket has holes which allow three different positions for attaching the center link. The position affects the draft sensing sensitivity. Should the following conditions occur, move center link to indicated holes to correct.

- Excessive hitch activity or hunting occurs in draft control operation - Use Upper or Middle Holes.
- Rear of implement rises too much when lifted. The implement weight which can be lifted is reduced slightly with center link attachment in lower holes - Use Upper or Middle Holes.
- Rear of implement drags the ground - Use Middle or Lower Holes.
- Draft control lever range is too small - Use Middle or Lower Holes.
- Hitch seems unresponsive in draft control operation and allows engine speed to drop too far before raising rockshaft - Use Middle or Lower Holes.

Implements with Category I mast height 457 mm (18 in.) will normally use the lower two attaching holes and implement with Category II mast height 483 mm (19 in.) will use the upper two holes.

Adjusting Hitch Side Sway

- Check implement operator's manual for instruction on whether to allow side sway.
- If sway is desired, install pin in outer hole, ensuring it goes through slot of inner sliding member.
- If sway is not desired, move draft link to desired position.
- Install pin in one of five fixed position holes that lines up with one of the holes (not slot) of the inner member.
- Adjust opposite side sway bar to same position.

Leveling the 5225, 5325, 5425, 5525, 5625 Hitch

Lower implement to take weight off hitch and adjust center link to level implement front-to-rear. Dont attempt to overextend center link beyond limits of locking clip or lift links past the stops. Link body threads could be damaged. Maximum adjustment range of the center link can only be obtained if the ends are positioned equally within the body when attached to an implement. On later model tractors make sure the center link does not unscrew past the extension limit groove cut into threads. Unlatch locking clip. Rotate center link body: CLOCKWISE to lengthen center link. COUNTERCLOCKWISE to shorten center link. Latch locking clip.

Adjust right link to level implement side-to-side. Lift locking handle and rotate 90° to engage slot onto roll pin. Turn locking handle: CLOCKWISE to raise draft link. COUNTERCLOCKWISE to lower draft link. Lift handle and rotate 90° to engage slot onto locking tab of lower body to prevent change of adjustment during operation.

Left lift link is also adjustable in length to accommodate two different length right lift link assemblies used, depending on tire size. The following adjustments will provide optimum hitch leveling: Right lift link, center threaded section measures 316 mm (12-7/16 in.) long: Adjust the left lift link to 550 mm (21-5/8 in.) from pin-to-pin (lateral float locked out).

Right lift link, center threaded section measures 266 mm (10-1/2 in.) long: Shorten the left lift link to 450 mm (17-7/16 in.). To change the left lift link length: Remove upper lift link pin. Rotate the upper end assembly: CLOCKWISE to shorten. COUNTERCLOCKWISE to lengthen. Install upper pin and locking pin.

Adjusting Lateral Float

To allow draft link to rise slightly as implement follows ground contour, put pin head and rectangular washer in vertical position.To hold implement rigid, place pin head and rectangular washer in horizontal position.

Float position: Hitch-mounted implements (cultivator or mower), which have ground gauging skids or wheels which may cause the implement to twist relative to the tractor. Rigid position: Plows and ground engaging implements that should not twist relative to the tractor.
