John Deere 5055E, 5045E, 5065E, 5075E Hydraulics and Hitch

John Deere 5045, 5045, 5065, 5075 Hydraulic System

Warm Hydraulic System Oil

Hydraulic system may be slow to function when JD 5065E, 5055E, 5045E, 5075E tractor is started in cold weather. This is because cold oil will not flow easily through the filter screen or hydraulic system filter. Steering will slow until system warms up. Hydraulic system will function normally when oil warms up.

To prevent damaging hydraulic pump or relief valve. Dont exceed two to three minutes warm up time. Depress clutch pedal, start engine and idle at about 1000 rpm. Turn and hold steering wheel in full left or right turn.

Control Lever and Coupler Identification

Movement of SCV 1 lever fore and aft operates coupler (No. 1) receptacles.
Movement of SCV 2 lever fore and aft operates coupler (No. 2) receptacles.
Coupler I has a detented float position when SCV 1 lever is moved in the fully forward direction.
Coupler II has a regenerative position when SCV 2 lever is moved in the fully forward direction.

The joystick (if equipped) has two basic directions of movement to control oil flow to the mid-mount couplers, located on the side of the JD 5045, 5055, 5065, 5075 tractor.
Forward and backward operates coupler 1.
Inward and outward operates coupler 2.
The joystick detents to a float position when moved fully forward.
The joystick detents to regenerative position when moved fully outward.

Connect Cylinder Hoses

A - Coupler II Receptacle (If Equipped), B - Coupler I Receptacle, C - Dust Plug (Black) (If Equipped), D - Dust Plug (Red)

- Remove dust caps from hose end. Pull dust plug (C) or (D) from couplers.
- Make sure hose end and coupler receptacles are clean.
- Check hoses to see which is used for extending cylinder. This hose must be connected to a coupler receptacle (A) or (B) in order for cylinder to extend when SCV levers are moved rearward or inward.
- Hydraulic hoses can fail due to physical damage, kinks, age and exposure. Check hoses regularly. Replace damaged hoses.

Connect SCV

To connect each hose, push hose tip firmly into coupler receptacle. Pull lightly on hose to make sure positive connection was made.

Mid-Mount Valve (If Equipped)

A - Bucket Cylinder-Rod End, B - Bucket Cylinder-Head End, C - Lift Cylinder-Head End, D - Lift Cylinder-Rod End, E - Caps

- Match hoses to couplers using color-coded dust caps/plugs. Hose connections at mid-mount valve are color-coded. A. Yellow (Bucket Cylinder - Head End). B. Black (Bucket Cylinder - Rod End). C. Blue (Lift Cylinder - Head End). D. Red (Lift Cylinder - Rod End).
- Remove dust caps from hose ends. Pull dust plugs from valve couplers.
- Hydraulic hoses can fail due to physical damage, kinks, age and exposure. Check hoses regularly. Replace damaged hoses.
- Make sure hose end and couplers are clean, push hose tip firmly into coupler. Pull on hose to make sure positive connection is made.
- Connect mating (color-coded) plugs and caps (E) together.

Connect Single-Acting Cylinder

In order for lever to work properly, a single-acting cylinder should be connected only to SCV 1 Outlet in the extend position (top coupler). Volume of oil required to extend cylinder must not lower transmission-hydraulic oil level below lower sight glass. Check oil level with cylinder fully extended. Push SCV 1 control lever full forward to use “float” position to lower single-acting cylinder. “Float” position allows a cylinder to extend and retract freely and uses no engine power.

Extend/Retract Cylinder - SCV 1

Extend Cylinder - Pull lever to the rear of neutral and hold it against spring pressure. This extends cylinder (up arrow) connected to couplers 1 and in most cases raises implement. Lever returns to neutral when released.

Retract Cylinder - Push lever forward and hold it against spring pressure. This retracts cylinder connected to SCV 1 couplers and in most cases lowers implement. Lever returns to neutral when released.

Float Position - Push lever full forward into detent to operate Float feature. Float operation allows cylinder to extend and retract freely, such as when an implement follows ground contour. When Float is not needed, manually move lever back to neutral position to prevent accidental use of “Float”.

Extend/Retract Cylinder - SCV 2 (If Equipped)

Extending Cylinder - Moving lever rearward against spring pressure will extend a cylinder connected to the SCV 2 coupler receptacles.

Retracting Cylinder - Moving lever forward against spring pressure will retract cylinders connected to the couplers 2.

Use Power Beyond Attachment - Power beyond is designed for operations of orbital motors or any application where continuous high volume hydraulic oil flow is needed. To use power beyond further remove three plug from power beyond and attach oil supply hose to mid mount supply valve line, oil return line to mid mount valve return line and excess return line to mid mount excess line. When not in use plug power beyond and mid mount valve.

5065E, 5055E, 5045E, 5075E John Deere Joystick Function (If Equipped)

The Control lever or the SCV 1 and SCV 2 has four directions of movement to enable simultaneous controls of two functions.

Forward and back direction has the following positions:

- Pulled fully rearward-Extend position SCV 1 is normally connected to the loader boom cylinder and raises when the lever is pulled rearward.
- Spring centered-Off and lock position SCVs are locked to hold the boom and bucket in position.
- Pushed slightly forward-Retract position Boom cylinder is lowered, valve can be metered to control rate of lowering.
- Pushed fully forward-Float position SCV connects both cylinder ports to the return circuit. Loader boom can move freely to follow ground contour. Lever must be manually returned to neutral.

Inward and outward direction has the following position:

- Pushed slightly outward-Extend position SCV 2 is normally Connected to the bucket cylinder and dumps when the lever is moved to the right.
- Pushed fully outward-Regenrative position Provides faster loader bucket dump. Reduces cavitation. Lever returned to neutral by valve spring.
- Pulled inward-Retract position. Flow to the bucket cylinder can be metered to slowly roll the bucket upward.

TRANSPORT LOCK - Loader control lever has a transport lock. Pull the transport lock lever upwards to lock the lever and push it downwards to unlock.

Adjust Cylinder Stop

Working stroke of remote cylinder is adjustable. Cylinder retracts only until it contacts movable stop, then stops automatically.

- Lift lever. Slide adjustable stop to desired position.
- Push lever down firmly. Be sure lever will not contact stop rod arm.
- Be sure stop clamps securely on rod. If it does not, lift lever and rotate it clockwise, then push it down firmly.

Disconnect Cylinder Hoses

- If possible, retract remote cylinder as much as possible to protect cylinder rod from damage.
- With as much hydraulic pressure relieved as possible from hoses, pull hoses from couplers.
- Make sure dust plugs for receptacles and dust caps for hoses are clean, then install dust plugs.

Remote Hydraulic Cylinders Troubleshooting

Direction of remote cylinder travel is reversed Improper hose connections. Reverse hose connections

Hoses will not couple Improper hose male tips. Replace tip with ISO standard tips.

Remote cylinder will not lift load Excessive load. Reduce load.
Hoses not completely installed. Attach hoses correctly.
Incorrect remote cylinder size. Use correct size cylinder.

Direction of travel reverses on II SCV. SCV lever moved to regenerate position. Reverse hose couplings.

JD 5045E, 5055E, 5065E, 5075E 3-Point Hitch

Rockshaft Control Levers

- The rockshaft position is controlled by two levers, the position control lever and the draft control lever.
- The rockshaft position control lever raises the hitch when pulled rearward, and lowers the hitch when moved forward.
- The draft control lever, controls hitch position relative to draft loads.

Set Control Lever Stop

- Position control lever stop is used when operating depth or height needs to be repeated.
- Operate implement for a few minutes to determine proper depth or height.
- Loosen lever stop, and slide against position control lever. Lock stop in position by turning in a clockwise direction.
- Rockshaft will now lower to same position each time control lever is pushed forward to the stop.

Position Control

- To prevent unexpected movement of rockshaft, place draft control lever, in a full forward position before attaching an implement.
- Put draft control lever, forward when you dont want rockshaft to adjust automatically to draft load, such as attaching implement to 5055, 5045, 5065, 5075 John Deere tractor.
- Use position control lever to control hitch movement and depth.

Transport of implements and end of field turn-around. Position control lever should be moved fully rearward for transport for both load and non-load sensing usage. Constant Depth of implements on level terrain and for non-ground engaging implements such as spreaders or sprayers. Place position control lever at depth desired. Float operation for implements with skids or depth gauge wheels designed to carry full implement weight. Push both levers all the way forward so implement can follow the ground contour. Lift links can be adjusted for lateral float.

Draft Control

The rockshaft is equipped with variable draft control system.

Use draft load sensing when: 1) Operating with a fully mounted implement in hill and swale terrain. The implement will raise and lower to follow the ground contours while maintaining a nearly constant depth. 2) 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.

Draft control lever controls amount of load required before hitch responds. With lever placed fully forward to the position marked “OFF”, there is no draft sensing. Placing the lever toward the rear position reduces the amount of draft load required to override the position setting set by the position control lever and raise the rockshaft. Draft sensitivity ranges can be changed by repositioning the center link.

For draft load sensing operation:

- Initially place position control lever in its fully rearward position and the draft control lever in the fully forward (least draft) position.
- With John Deere 5045E, 5055E, 5065E, 5075E tractor moving, push position control lever forward to set implement operating depth. Set position control lever stop so control lever can be brought back to the same position.
- The operating depth set-up will prevent the rockshaft from lowering all the way when the JD tractor begins to slip. Then pull draft sensing lever rearward until desired draft sensing sensitivity is obtained.
- The position control lever can also be raised slightly to override the draft control setting to help get through slippery spots without getting stuck.
- The position control lever can be moved fully rearward to raise the hitch at the end of the field.

Adjust Rockshaft Rate-of-Drop/ Implement/Transportation Lock - Rockshaft drops faster when a heavy implement is attached. Adjust rate-of-drop knob so that it is slow enough to be safe and prevent implement damage. Turn rate-of-drop knob, located under the seat, clockwise to slow rockshaft drop. Turn knob counterclockwise to increase rate-of-drop. Rate-of-drop knob is also called implement lock. When knob is fully screw in, implement will not lower down even if position control lever is fully down. Use implement lock while transporting implement.

Prepare Implement

When attaching Category 1 implements to the JD 5065, 5055, 5045, 5075 tractor, sway chains may need lengthening to prevent binding and limiting full raise of the hitch.

Category 1 three Point Hitch is narrower and is used on smaller implements than Category 2 implements. Refer to the chart below to identify implement category. Category 2 implements should have the top hole of the implement mast located 610 mm (24 in.) above the lower pins. Drill another hole in top mast or extend top mast if necessary.

Convert Category 2 Hitch to Category 1 (If Equipped)

- Center link end is sized for Category 2 implement attaching pin.
- If Category 1 implements are to be used, the Category 2 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.

Position Center Link

The draft sensing center link attaching bracket has holes which allow three different positions for attaching the center link. The position effects the draft sensing sensitivity. Standard position is Lower Hole.

Move the center link attachment to Middle holes if:

- Excessive hitch activity or hunting occurs in draft control operation.
- The rear of the implement raises too much when lifted. The implement weight which can be lifted is reduced slightly with the center link attachment in the lower holes.
- The draft control lever range is too small.

Move the center link attachment to holes Lower if:

- The hitch seems unresponsive in draft control operation and allows the engine speed to drop too far before raising the rockshaft.
- The rear of the implement droops and drags the ground as the implement is lifted.

Upper hole eliminates nearly all draft sensing. Implements with Category 1 mast height 457 mm (18 in.) will normally use the upper two attaching holes. Implements with Category 2 mast height 610 mm (24 in.) will normally use the upper two attaching holes.

Attach Implements to 3-Point Hitch

Fixed Draft Links

- Be sure drawbar will not interfere. If necessary, move drawbar ahead, or remove it. Check for any other potential interference.
- Prevent unexpected movement of rockshaft by placing draft sensing lever in the forward or OFF position before attaching implement to hitch.
- Back 5075E, 5055E, 5065E, 5045E John Deere tractor up to implement so that hitch points align. Engage parking brake and stop the engine Before leaving the tractor seat.
- Slip draft links over implement hitch pins, and retain with quick-lock pins.
- Locking pins can be stored on draft links (through holes in sway chain ears) when not in use.
- To remove center-link from transport hook, lift center link locking clip and rotate tab to rear of center link clip.
- Attach center link to implement top mast. Adjust center link and lift links as necessary.
- To avoid bodily injury or machine damage whenever an implement, implement quick coupler, or other attachment is connected to the JD tractor 3-Point Hitch, check full range of operation for interference, binding or PTO separation. Using position control lever, lower and raise implement slowly and check for any point of interference.

Telescoping Draft Links (If Equipped)

- Position tractor in line with hitch points. Back JD tractor up close to implement. Place transmission in PARK and stop engine.
- Move button toward center of tractor and pull out draft link end. Slip draft link end over implement hitch pin. Retain with quick-lock pin. Repeat on other side.
- Raise or lower draft arms to align ends with arms, then slowly back up tractor to lock ends in place.
- Perform steps 4—7 from previous procedure (fixed draft links).

Adjust Hitch Side Sway - Check implement operator's manual for instruction on whether to allow side sway. Dont shorten chains so short that they do not allow hitch to be raised completely. If chain prevents hitch from raising, hydraulic relief valve will open, causing excessive oil heating, pump damage or equipment damage. Use spring or rubber strap to keep draft links out of rear tires when draft links are not attached to implement. Implement side sway should be adjusted when the rockshaft is raised for transport by loosening the jam nut on the threaded link and turning the center rod to increase or decrease the length of chain. Tighten jam nut again when adjusted.

Level the JD 5055E, 5045E, 5065E, 5075E Hitch

- Lower implement to take weight off hitch. 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. Adjust center link to level implement front-to-rear. Unlatch locking clip. Rotate center link body clockwise to lengthen center link or counterclockwise to shorten it. Be sure to latch the locking clip.
- Adjust right-hand link to level implement side-to-side. Lift locking handle and turn 1/4 turn to engage slot onto roll-pin in the center portion of the lift link. Turn crank handle clockwise to raise draft link. Turn crank handle counterclockwise to lower draft link. After adjustment, lift handle and turn to engage slot onto the lower body
to prevent change of adjustment during operation.
- The left-hand lift link is also adjustable in length to accommodate different tire sizes. To change the left-hand lift link length, remove the upper lift link pin and rotate the upper end assembly clockwise to shorten or counterclockwise to lengthen, and then reinstall the upper pin and locking pin. Adjust left and right lift links to
accommodate various tire sizes. Set the lift links to have fully-lowered draft link balls approximately seven inches off the ground for greatest range of usable hitch motion.

Adjust Lateral Float

To allow the draft link to raise slightly as implement follows ground contour, place head of float pin and the rectangular washer on the inside end of the pin in a vertical position. To hold implement rigid, place head of float pin and the rectangular washer in the horizontal position.

Use lift link pins in the float position for hitch-mounted implements such as a cultivator or mower, which have ground gauging skids or wheels which may cause the implement to twist relative to the John Deere 5045, 5055, 5065, 5075 tractor. Use the rigid position for implements such as plows and ground engaging implements that should not twist relative to the tractor.

Adjust Rockshaft Lever Friction

To keep the position and draft sensing levers in their set positions. SCV levers, right-hand fender and console removed for clarity.

- Loosen jam nut.
- Turn adjusting cap screws clockwise to increase friction, counterclockwise to decrease friction. Turn cap screws equal number of times.
- Retighten jam nuts when adjustment is complete.

Observe Drawbar / Wagon Hitch Load Limitations - Certain heavy equipment, such as a loaded single-axle trailer, can place excessive strain on drawbar. Strain is greatly increased by speed and rough ground. Static vertical load on drawbar/wagon hitch should not exceed 250 kg (552 lb). Drive slowly with heavy loads.

Lubricate 3-Point Hitch - Lubricate right lift link and left lift link with several shots of multipurpose grease.
