Common Problems with the Massey Ferguson 2607H

Based on owner experiences and mechanic insights, the following are the most frequently reported issues with the 2607H, along with their causes and solutions.

1. Engine Dies Randomly When PTO Is Engaged

One of the most perplexing issues reported by 2607H owners is the engine shutting off unexpectedly when the Power Take-Off (PTO) is engaged. This problem manifests as a sudden engine kill, akin to turning off the ignition key, and occurs either immediately after engaging the PTO or after hours of operation.

Cause

The primary culprit is often the Operator Presence Safety Module, which is designed to shut off the engine under specific conditions to ensure operator safety. According to the operator’s manual, the Safety Module triggers an engine shutdown by deactivating the ECUT15 Relay when:

• The seat switch detects no operator presence.
• The PTO is engaged.
• The hand parking brake is disengaged.

In many cases, owners find that the seat safety switch has been bypassed or hardwired by previous owners to always indicate operator presence. However, improper wiring can cause the Safety Module to misinterpret the switch’s state. For example, a hardwired seat switch in the closed position signals that no operator is present, prompting the Safety Module to shut down the engine when the PTO is engaged and the parking brake is off. Additionally, a loosely adjusted parking brake may intermittently fail to engage its safety switch, leading to random shutdowns after vibrations or bumps in the field.

Solution

To resolve this issue, follow these steps:

1. Inspect the Seat Safety Switch:
   • Check if the seat switch is hardwired. If it’s in the closed position, it incorrectly signals no operator presence.
   • Disconnect the switch from the main wire harness to set it to the open position, which tells the Safety Module an operator is always present.
   • Test the tractor with the PTO engaged to confirm the engine no longer shuts off.
2. Adjust the Parking Brake:
   • Ensure the parking brake is properly tensioned to make consistent contact with its safety switch.
   • Verify the switch’s wiring, as some 2607H models have a four-terminal switch where incorrect terminal use can invert the signal (e.g., closed when disengaged).
3. Check the ECUT15 Relay and PTO Switch:
   • Test the ECUT15 Relay for signs of failure, such as intermittent operation or corrosion.
   • Inspect the PTO safety switch for loose connections or intermittent shorts, which could falsely signal engagement.
4. Examine the ECU and Wiring:
   • The Electronic Control Unit (ECU) cuts power to pin 71 to shut off the engine. Ensure the ignition switch and ECUT15 Relay wiring to pin 71 are intact.
   • Use a multimeter to check for intermittent shorts between the PTO sensor and the instrument panel.

Preventive Measures

• Regularly inspect safety switch connections for corrosion or wear.
• Follow the operator’s manual for parking brake adjustments every 50 hours.
• Avoid bypassing safety switches without understanding their impact on the Safety Module’s logic.

2. Tachometer Malfunctions When PTO Is Engaged

Another common issue is the tachometer displaying incorrect readings or failing entirely when the PTO is engaged, particularly in cold or wet conditions.

Cause

Unlike older tractors with mechanical tachometer cables, the 2607H uses an electrical speed sensor and an alternator-generated square wave signal to drive the tachometer and digital hour meter. The alternator’s W (waveform) terminal outputs a frequency proportional to engine speed. The issue often stems from:

• Fan Belt Slippage: A loose or wet fan belt can slip, causing the alternator’s square wave frequency to misalign with the engine speed, resulting in erratic tachometer readings.
• Environmental Factors: In winter, snow or moisture entering the tractor’s side openings can wet the fan belt, exacerbating slippage.
• Alternator Issues: Faulty connections at the alternator’s W or IG terminals may disrupt the signal.

Solution

1. Check Fan Belt Tension:
   • Verify the fan belt tension per the operator’s manual (recommended check every 50 hours).
   • Tighten the belt if loose, ensuring it grips the alternator pulley properly.
   • Replace the belt if worn or damaged.
2. Inspect for Moisture:
   • Check for snow or water ingress around the tractor’s side openings, especially when using attachments like snowblowers.
   • Consider adding a canopy or sealing openings to protect the engine compartment.
3. Test Alternator Connections:
   • Ensure the W terminal (waveform) and IG terminal (ignition) on the BOSCH G1S2 alternator are securely connected.
   • Use a multimeter to confirm the square wave output from the W terminal matches engine speed.

Preventive Measures

• Regularly clean and inspect the engine compartment for debris or moisture.
• Maintain proper fan belt tension to prevent slippage.
• Store the tractor in a dry environment during winter to minimize moisture-related issues.

3. Clutch Problems: Tractor Moves with Clutch Depressed

Owners frequently report that the tractor continues to move forward on level ground even when the clutch pedal is fully depressed, indicating a clutch engagement issue.

Cause

This problem typically arises from:

• Clutch Misadjustment: Improper clutch pedal free play or linkage adjustment prevents full disengagement.
• Worn Clutch Components: A worn clutch disc, pressure plate, or release bearing may cause the clutch to remain partially engaged.
• Mechanical Interference: Debris or damage within the clutch housing can impede proper operation.

In some cases, the clutch issue may indirectly affect other systems, such as the PTO or tachometer, by causing excessive vibrations or mechanical stress.

Solution

1. Adjust Clutch Pedal:
   • Follow the operator’s manual to adjust the clutch pedal free play and linkage.
   • Test the tractor to confirm the clutch fully disengages when depressed.
2. Inspect Clutch Components:
   • If adjustment fails, the tractor may need to be split to inspect the clutch disc, pressure plate, and release bearing.
   • Replace any worn or damaged components, ensuring proper alignment during reassembly.
3. Minimize Damage in the Interim:
   • Operate the tractor at idle when shifting gears to reduce strain on the clutch.
   • Avoid heavy loads until the clutch is repaired.

Preventive Measures

• Regularly check clutch pedal free play as part of routine maintenance.
• Avoid aggressive shifting or overloading the tractor to prolong clutch life.
• Address clutch issues promptly to prevent secondary damage to the transmission or PTO.

4. PTO Continues Spinning After Clutch Depression

Some owners report that the PTO continues to spin even after fully depressing the clutch pedal, which is unexpected for a tractor with an independent PTO.

Cause

The 2607H features an independent PTO activated by a hydraulic clutch. The issue may result from:

• Hydraulic Clutch Malfunction: A faulty PTO clutch pack or hydraulic control valve may fail to disengage the PTO.
• Transmission Shaft Issue: The transmission input shaft, which connects to the PTO clutch, may not fully stop when the clutch is depressed, indicating a clutch or shaft alignment problem.
• Sensor or Wiring Fault: A malfunctioning PTO safety switch or sensor may incorrectly signal engagement.

Solution

1. Test Clutch Operation:
   • Confirm whether the drivetrain stops when the clutch is depressed. If it does, the issue is likely specific to the PTO clutch.
   • If the drivetrain also continues moving, address the clutch issue first (see above).
2. Inspect PTO Clutch:
   • Check the hydraulic fluid level and quality for the PTO system.
   • Inspect the PTO clutch pack for wear or damage, replacing components as needed.
   • Verify the hydraulic control valve for proper operation.
3. Check PTO Safety Switch:
   • Test the PTO switch for correct operation (closed when PTO is off, open when engaged).
   • Repair or replace any faulty wiring or connections.

Preventive Measures

• Regularly service the hydraulic system, including fluid changes and filter replacements.
• Monitor PTO engagement for unusual noises or behavior, addressing issues early.
• Consult a dealer for persistent PTO problems, as they may require specialized diagnostics.

5. Check Engine Light and Limited Power Output

Some owners report a check engine light accompanied by the tractor not exceeding 1500 RPM or 1500cc, indicating a power limitation.
