John Deere 5065M, 5075M - Hydraulics and Hitch


John Deere 5065M, 5075M Hydraulics

Connect Cylinder Hoses to Rear SCV

Identify extend and retract hoses. Remove dust caps (if equipped) from hose end. Open coupler covers. Making sure hose end and coupler are clean, push hose tip firmly into selective control valve (SCV) coupler. Pull on hose to make sure positive connection was made. Connect extend hoses to top couplers and retract hoses to bottom couplers.

Connect and Operate Single-Acting Cylinder

Single-acting cylinder should only be connected to selective control valve (SCV) extend coupler. Volume of oil required to extend cylinder will lower transmission-hydraulic oil level. With cylinder fully extended, check oil level and fill to proper level. Pull Selective Control Valve (SCV) control lever back to pressurize and extend single-acting cylinder. Push SCV control lever full forward to float position to retract cylinder.



JD 5065M, 5075M - Operate Rear SCV Control Levers and Set Detents

Setting Control Lever Detents - Each section of the deluxe SCV has selectable detents, used to change control lever operations to meet operating requirements of different implements. Detent settings only affect extend and retract lever positions, not float. The three settings are: Continuous Detent (Motor), No Detent (Loader), Automatic Detent (Cylinder) Knob setting stop is in the top, center position.

SCV Section/Knob Position/Operation. SCV I - Turned clockwise for cylinder operation: Automatic Detent (Lever automatically returns to neutral when cylinder reaches end of stroke). SCV II - Centered for loader operation: No Detent (Lever returns to neutral when released). SCV III—Turned counterclockwise for motor operation: Continuous Detent (Holds lever in operating position until manually returned to neutral). Valve sections II and III can be set to continuous (motor) detent, but should only be used for intermittent applications (not exceeding 10 min/hr maximum) or hydraulic oil will overheat and damage tractor.

John Deere 5065M, 5075M - Operate Mid SCV Multi-Function Control Lever

Multi-function lever controls any hydraulically driven device connected to mid selective control valve (SCV), most commonly a loader. Multi-function lever and loader operation depend on hose to coupler connection. A single function operates when control lever is moved straight away from center, in one of four primary directions (front, back, left, or right). Front-Boom Lower. Full-front is a detented position used for float operations. Back-Boom Raise. Left-Bucket Rollback (Curl). Right-Bucket Tilt (Dump). Two functions operate simultaneously when lever is moved at 45° angles from primary directions, into a two-function zone. Two-function zones are: Boom Lower/Bucket Dump, Bucket Dump/Boom Raise, Boom Raise/Bucket Curl, Bucket Curl/Boom Lower.

When lever is released to spring-centered neutral position, mid-mount valve holds boom and bucket in position. Cylinder operating speed depends on how far from center the control lever is moved. When lever is first moved from center, hydraulic functions operate slowly, then move progressively faster as lever is moved further away from center, out to fast speed operating position. Third functions controlled by switch can be operated simultaneously with any single and two function operations. Float: Push lever full forward into detent when float is desired. Float position allows loader boom to move up and down freely while traveling over rough ground. Manually return lever to neutral when float is no longer needed.

Transport Lock - Transport lock does not lock out switch operated third-function hydraulics, which are active anytime the key is ON. Push IN to lock. Pull OUT to unlock. Lock is engaged when dashed line is in against body and lever does not move.

Third-Function (Electrohydraulic) - Switch controls third-function hydraulics connected to three-function mid-mount valve. Third-function hydraulics are active anytime the key is ON. Top half pressed: Attachment retract/raise (grapple open). Bottom half pressed: Attachment extend/lower (grapple close). Front switch is not operational in this application.

Manually Operating Third-Function (Electro-Hydraulic) Valve Section - Third-function (grapple) valve section can be manually operated if an electrical malfunction occurs. Insert a small diameter punch through access hole and push spool to either extend or retract cylinders as needed to release load.

John Deere 5065M, 5075M 3-Point Hitch

JD 5065M, 5075M - Attach Implements to 3-Point Hitch

Engine must be running for 3-point hitch control to work. Before attaching or detaching implement, place load/draft control into lowest setting. Use position control lever to raise or lower implement. DO NOT use rear quick raise/lower buttons. Be sure drawbar will not interfere. If necessary, move drawbar to fully retracted position or remove it. Check for any other potential interference.

Telescopic Draft Links

Back JD 5065M, 5075M tractor up to implement so hitch points align. Place transmission in park and stop engine. Move button or lock pin toward center of tractor and pull out draft link end. Raise or lower draft arms to align draft link ends with arms. Slip draft link end over implement hitch pin. Retain with quick-lock pin. Repeat on other side. Slowly back up tractor to lock ends in place.

Push tab backward and lift locking clip to release center link from transport hook. Attach center link to implement top mast. Adjust center link and lift links as necessary. Start engine. Using position control lever, slowly raise and lower implement and check for interference. If equipped with electrohydraulic hitch use quick raise/lower buttons or fender-mounted switches to raise and lower implement and check for interference.

Adjust Hitch Side Sway

If sway is desired, install pin in sway position outer slot, ensuring it goes through sway position inner slot. If sway is not desired, move draft link to desired position. Install pin in fixed position hole that lines up with one of the holes (not slot) of the inner sliding member. Adjust opposite side sway bar to same position. Additional fixed positions can be obtained by adjusting threaded end of stabilizer. Disconnect inner sliding member from draft link. Rotate stabilizer as necessary. Missing thread on stabilizer also acts as a stop indicator.

John Deere 5065M, 5075M - Level Hitch

Lower implement to take weight off hitch and adjust center link to level implement front-to-rear. Rotate center link body with handle. DO NOT disconnect center link by rotating body beyond limits. Rotate center link body: Clockwise to lengthen center link. Counterclockwise to shorten center link. Latch locking clip. 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 lift 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.

Adjust Lateral Float

Float Position: Ground following implements (cultivator or mower), use ground gauging skids or wheels to rise/lower slightly or twist as implement follows ground contour.

Rigid Position: Ground engaging implements (plows, rippers, disc) require fixed ground depth and alignment with tractor, no relative twisting.

John Deere 5065M, 5075M Drawbar

Attach PTO-Driven Implement

Keep JD 5065M, 5075M tractor PTO shield and driveline shields in place at all times. Make sure rotating shields turn freely. Before making adjustments, connections or cleaning PTO driven equipment, STOP the engine and wait for PTO drivelines to stop. 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 tractor (drawbar or 3-point hitch) before connecting PTO driveline. Raise hitch to full-up (transport) position if it is not to be used. Flip PTO shield up for clearance. With engine off, turn PTO shaft by hand to line up splines. Connect driveline to PTO shaft. Pull driveline to be sure it is locked to PTO shaft. Return PTO shield to down position. Check that all shields are in place and in good condition. WITH ENGINE STOPPED, check driveline shields on driveline by making sure they rotate freely on shaft. Lubricate or repair as necessary. Check for interference.

John Deere 5065M, 5075M - Select Correct PTO Speeds

Disengage PTO with switch before changing PTO speed with lever. NEVER use shiftable PTO lever to engage or disengage PTO. Lift black collar to move PTO shift lever, for cab tractors only.

Standard 540 Operation - No PTO speed selection required. Engage standard 540 PTO with switch. Standard 540 rpm power take-off speed is reached at 2100 rpm engine speed.

540/540E Operation - For standard 540 PTO operation (load requiring full engine power), move lever rearward into standard 540 speed position. For economy 540 PTO operation (lighter load), move lever forward into economy 540 speed position. In economic mode, engine operates at lower rpm to conserve fuel and reduce overall operating noise while still turning PTO shaft at 540 rpm. Economy 540 rpm power take-off speed is reached at 1645 rpm engine speed and limited to maximum engine speed of 1815 rpm.
