John Deere 345 Problems

If you’re a John Deere 345 owner, then you know that this tractor is built tough. But like all machines, it’s not without its problems. Here are some of the most common issues that owners have reported:

1. Transmission problems 

Some owners have reported that their 345s have had transmission problems, especially after years of use. This can be a major problem if not addressed early on, so keep an eye out for any unusual noises or shaking coming from the tractor.

2. Hydraulic issues

Another common problem with the John Deere 345 is hydraulic failure. This can cause the tractor to lose power and be difficult to control.

If you notice any leaks or unusual sounds coming from the hydraulics, it’s best to take your tractor in for service right away. 

3. Engine trouble

The engine is another key component of the John Deere 345 that can cause problems down the road.

Some common issues include blown head gaskets, oil leaks, and overheating. Again, these are serious problems that should be addressed by a qualified mechanic as soon as possible. 

4. Tire wear 

Finally, one issue that all John Deere 345 owners will eventually face is tire wear. Because this tractor is used for heavy-duty work, the tires will eventually need to be replaced.

How To Fix Jhon Deere 345 Problems

Whatever this problem is, it’s a pain to deal with. But you can solve it yourself. While it’s not a quick fix, there are some simple things you can do to make your John Deere 345 tractors easier to use and run more reliably.

1. Transmission Problems Fix

To fix the trouble shifting into gear, it’s all in the fluid. If there is too much fluid in the transmission system, you can manually drain some of it out. With the pan off, use your hand and pull on the dipstick to remove as much fluid as you can without pulling out any parts. 

If there are undesirable particles in your transmission oil (for example dirt), spray your dipstick with brake cleaner to get rid of them. Once you’ve removed the excess oil, put some fresh fluid in your transmission.If the problem is not solved, you have to replace the transmission.

2. Oil leaks Problem Fix

To fix an oil leak in your John Deere 345 tractor, you need to make sure that there is no damage on your transmission. Open the drain plug and remove a small amount of oil from the pan. If there are metal particles in your oil (for example screws), spray some brake cleaner on them and let it sit for a few minutes.

3. Choke Knob Problems Fix

To fix your choke knob that sticks, the first thing you need to do is clean the area where it’s located. With a hose and water, soak down that part of the engine.

If your tractor has a distributor problem, you can have it repaired or replaced. You can buy an aftermarket distributor from an auto parts store (depending on your John Deere 345 model) for about $50-$60.

4. Hydraulic Issues Fix

If you want to fix hydraulic issues with your John Deere 345 tractor, you will need to check the oil level. Place a magnet on top of the valve cover and see if it points out at different positions. If it’s not pointing out, then there is a problem with your engine.

If you have a problem with the belt, you can easily fix it. You can either buy new hardware or find a different belt that fits your machine. You’ll need to know where your belt is on your specific model.

5. Tire wear Fix

Out of all the different problems in your John Deere 345, tire wear is probably one of the easiest to fix. You’ll need to check the air pressure in each one of your tires. The air pressure will depend on the weather and conditions (for example flat land or heavy hills), but you should use your owner’s manual as a guide.

To figure out if you have tire wear problems, compare two tires with each other and see how they compare. Look at the numbers on the side of each tire to find the size and determine if one tire is larger than the other.

To adjust your John Deere 345 tires, you can use a tire pressure gauge. For each tire, fill up the recommended amount before starting out.

Is a John Deere 345 a Good Tractor?

Yes, the John Deere 345 is a good tractor. It is reliable and has a lot of features that make it a great choice for farmers and ranchers. Some of the features that make it a good tractor include its four-wheel drive, hydrostatic transmission, and power steering.

What Years Did They Make John Deere 345?

The John Deere 345 was made from 1995 to 2001. It was a popular model during its production run and is still sought after by many lawn and garden enthusiasts today. The 345 featured a 20-horsepower liquid-cooled engine and a 42″ deck.

What Does a John Deere 345 Weigh?

The John Deere 345 is a lawn and garden tractor that was produced from 1995 to 2001. It featured a 20 horsepower (15 kW) V-twin engine and a 42″ mid-mount mower deck. The 345 was available in both two-wheel drive and four-wheel drive models.

The two-wheel drive model weighed in at 711 lbs (322 kg), while the four-wheel drive model weighed in at 749 lbs (340 kg).

What Transmission is in a John Deere 345?

The John Deere 345 lawn tractor was equipped with one of two possible transmissions. The first option was a gear drive transmission with six forward and two reverse gears. The second option was a hydrostatic transmission.

This type of transmission is becoming increasingly popular on lawn tractors and other types of garden equipment because it offers several advantages over the older gear drive type. 

One advantage of the hydrostatic transmission is that it is infinitely variable, meaning that the operator can select any speed between zero and the maximum without having to shift gears. This can be a big time saver when mowing around obstacles or working in tight spaces where precise control is needed.

Another advantage of this type of transmission is that it eliminates much of the maintenance required by a gear drive system. There are no oil changes necessary and fewer moving parts mean there are fewer opportunities for something to break down.

If you happen to own a John Deere 345 lawn tractor with a hydrostatic transmission, there are still some basic maintenance chores that will need to be performed from time to time.

The main thing you’ll need to do is keep an eye on the fluid level in the reservoir and add more if necessary. You should also check the owner’s manual for your particular model to see if there are any special procedures recommended by the manufacturer for servicing this type of transmission.

John Deere 345 Won’t Start

If you own a John Deere 345 lawn tractor, you may eventually have problems starting it. This is a common issue that can be caused by several different things. In this blog post, we’ll go over some of the most common reasons why your John Deere 345 won’t start, and what you can do to fix it.

One of the most common reasons for a John Deere 345 not starting is that the battery is dead. If your tractor has been sitting for a while, or if you haven’t used it in a while, the battery may simply need to be recharged. You can do this by hooking up a charger to the battery terminals.

Another possibility is that the battery itself is bad and needs to be replaced. Another common reason for a John Deere 345 not starting is that there’s something wrong with the fuel system. This could mean that there’s dirt or debris in the fuel line, or that the fuel filter needs to be replaced.

It could also mean that there’s water in the gas tank – this can happen if you leave your tractor outside in rainy weather without putting a cover over it. If water has gotten into the gas tank, you’ll need to drain it out and refill it with fresh gasoline before trying to start the tractor again.

If neither of these solutions fixes the problem, then it’s likely that there’s an issue with one of the tractor’s electrical components. The first thing to check would be whether or not any fuses have blown; if so, replacing them should solve the problem.

If not, then it’s possible that one of the coils or spark plugs isn’t working correctly – this will usually require professional assistance from a mechanic or dealership service department to fix properly. Hopefully, this blog post has helped you troubleshoot why your John Deere 345 won’t start.

If none of these solutions work, then please feel free to bring your tractor into our shop and we’ll take a look at it for you – we’re always happy to help!

John Deere 345 Time Delay Module Symptoms

John Deere 345 Time Delay Module Symptoms The John Deere 345 time delay module is used to delay the engine start when the key is turned on. This module is located in the engine compartment on the left side of the engine near the front.

The time delay module has 4 wires going to it, 2 black and 2 red. The black wires are for the ground and the red wires are for power. If you have a problem with your John Deere 345 not starting, it could be due to a problem with this module.

If your John Deere 345 will not start, first check the battery. Make sure that it is fully charged and that there are no loose connections. If everything looks good with the battery, then move on to checking the time delay module.

You can do this by using a multimeter to test for continuity between each of the 4 terminals on the module. There should be continuity between all 4 terminals when they are connected together in pairs (black-black, black-red, red-black, red-red).

If there is no continuity between any of these pairs of terminals, then replace the time delay module.

If you’re a John Deere 345 owner, then you may have experienced some ignition module problems. Here’s what you need to know about this issue and how to fix it. The John Deere 345 is a great lawn tractor, but like any machine, it can have its share of issues.

One problem that has been reported is with the ignition module. Some owners have said that their tractor will suddenly shut off while they’re using it, and they believe the ignition module is to blame. There are a few things that could cause this problem.

It could be a faulty connection between the module and the spark plugs, or there could be an issue with the module itself. If you’re experiencing this problem, the first thing you should do is check all of the connections to make sure they’re tight and secure.

However, if there’s no spark at all, then chances are good that the ignition module is defective and needs to be replaced.
