1. Brake Issues

Brake issues are linked with the mowing machine pulling to one side, mobility issues and disengagement of the brake.

If the mower does not move, then you need to check critical components such as linkage, park brake lock lever assembly, and springs to troubleshoot the issue. 

For a mower that moves to one side, you need to check parts such as friction disks, separator plates, and brake return springs. 

You can also inspect components such as brake linkage adjustment, brake friction disks, and brake separator plates to fix the disengagement of brakes. 

Causes 

• Worn or damaged park brake lock lever assembly
• Stretched, broken or missing springs
• Broken, missing or stretched brake return springs 
• Worn or damaged separator plates 
• Worn or damaged friction disks
• Faulty brake linkage adjustment.

Fix

• Repair or replace the brake lock lever assembly
• Change springs as necessary.
• Replace springs as necessary.
• Change worn or damaged separator plates.
• Adjust linkage to solve the issue of disengagement of brakes. 
• Change damaged or worn friction disks.

Note: This condition can be caused by other components other than brakes. You can also inspect the power train system if the following conditions do not troubleshoot the issue.

2. Hydraulic Problems

Hydraulic problems are one of the common issues associated with the John Deere 1445 mower. Several homeowners try to change the transmission fluid with the hope that the mower will be okay but it may not.

It could be that the spring and ball become loose and jams the spool while the mower’s retaining screw backs out. Another reason could be a dirty air filter

Causes

• The spring and ball become loose and jam the spool, causing the retaining screws to back out.
• Dirty air filter

Fix

• Make sure that you insert the spool in a neutral position and tighten your indent screw. Reconstruct the valve if there is a leakage in the control valve.
• If you notice a blow-by on the cylinder, change your seals after you disassemble the tractor’s piston. If the fluid leakage of the cylinder does not stop, it means that the piston seal is faulty. This means that you should repair the cylinder.
• To check if the valve spool requires repair, disconnect the a and b ports immediately after the valve. After turning on the system, look for seepage from the disconnected lines. Make sure that you do not move the lever.
• Ensure that the air filter is clean.

3. Overheating

This is one of the common problems of the John Deere 1445 mower. When it overheats, the PTO of the mower shuts off. In addition, your mower fan will not engage too.

Causes

• Defective sensors/PTO solenoid/BCU

Fix

• Make sure that the engine-to-rear end drive belt and bypass rod are well inserted. It is advisable not to carry out servicing on the transaxle by yourself. 
• Contact a dealer to help you fix this.
• Replace the PTO solenoid valve after experimenting with new switches and sensors. Otherwise, you may need to replace or bypass the BCU to solve the issue.

4. Bad Wiring on Fan

Bad wiring on the fan can hinder the functionality and performance of your John Deere 1445 mower. This issue can be caused by other switches that are misaligned.

Causes

• Switches are misaligned

Fix

• Ensure that you seek the help of a professional to fix issues with the RIO switch wiring and the park brake switch.

5. Electrical Problems

Electrical issues can cause the John Deere 1445 model not to start. Even if the mower starts, it may stall frequently. When you turn your key, you will notice that the mowing machine isn’t working.  

Your mower can also encounter electrical problems if the cable of the throttle melts into the housing. This can cause your throttle not to move.

Causes

• Poor and defective wiring
• Hot or burnt battery terminals

Fix

• It is advisable to contact a technician to fix the issue of poor or defective wiring.
• If you notice that the battery terminals are getting hot, make sure that you contact the dealer to help you find the issue.

6. Stalling/Starting Issues

The 1445 model is prone to stopping and stalling. In this case, the mowing machine may operate for about ten to sixty minutes and it will stall or stop.

The causes for this can be that the engine’s compression has exceeded its suction, or the fuel line is not well-positioned.

Causes

• The fuel line is not positioned correctly
• The valve decompression setting may cause the engine to start with excessive compression.
• The mower engine’s compression has exceeded its suction

Fix

• It is advisable to contact a technician to help fix the issue with improper positioning of the fuel line and compression problems.
• To fix the engine compression that has exceeded its suction, you need to take off the gas cap and allow it to inflate until it becomes empty. 
• Then, you can now change the gas cap and then restart. 
• Ensure that you set the valves accordingly when the piston is ¼-inch past the top dead center.
• Ensure that you set intakes at 0.04.
