The John Deere D105 has long been a reliable option for lawn care, but like any machine, it can face mechanical issues over time. One recurring issue users have reported is with the transmission, particularly the tractor’s struggles going uphill.
This article aims to outline the common problems experienced by D105 owners and possible solutions to resolve these issues.
Symptoms of Transmission Problems
The typical symptoms that suggest a problem with the D105 transmission include:
- Sluggish movement going uphill, worsening over time
- Intermittent forward movement, eventually leading to complete loss of traction
- Temporary relief of symptoms after the tractor cools down, but the issue reappears once the tractor heats up again.
Possible Causes and Solutions
Given these symptoms, let’s consider what might be causing the problems and how they could be fixed.
Drive Belts and Pulleys
- Problem: The drive belts and pulleys may be worn or damaged.
- Solution: Inspect the drive belts and pulleys. Replace them if necessary.
- Problem: Faulty external components around the transmission area.
- Solution: Before rushing to replace the entire transmission, which can be costly, thoroughly inspect the surrounding parts, including variators and pulleys. Sometimes, the fault may lie in one of these components.
- Problem: Loose variator belt.
- Solution: If you notice the variator belt isn’t as snug as it should be, consider replacing it or investigating whether it’s improperly seated.
- Problem: Old or contaminated hydraulic oil can lead to performance issues.
- Solution: Although the D105 doesn’t have a hydrostatic transmission, it’s a good idea to check the quality of the hydraulic oil. Replace the oil if necessary.
Serial Number and Recalls
- Solution: Verify if your D105 is subject to any recalls. Although some models have been, not all serial numbers fall within the recall range. If your machine is included, you may be entitled to a free fix.
- Problem: If you’ve ruled out all the above factors, then the last resort might be to replace the transmission.
- Solution: Be cautious when purchasing a new transmission online, as some users have reported receiving incomplete or damaged parts from online retailers. Buying from a reputable John Deere dealer might be a safer bet.
- Hills are challenging for the D105’s transmission. If you regularly mow hills, consider a more robust model.
- Never tow anything with the D105. It is an entry-level mower that can’t tolerate additional stress.
Some users have found success by replacing the springs on the secondary variator, which was compressed due to heat build-up. This is a relatively low-cost fix that could resolve the problem.
