How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Hard, and sometimes impossible shifting into first and reverse is caused by the clutch disc not moving away from the spinning flywheel. This is commonly referred to as the “clutch is not releasing”. The number one cause is the hydraulic system that operates the clutch is leaking and has low fluid.
Misadjusted, damaged or stretched shift linkage or cables can keep an AT from going into gear when moving the shifter. Check your owner`s manual, because some vehicles have shift cables that are adjustable. Adjusting a cable is a one-time fix you can make before taking your car in for service.
This could be caused by a worn clutch, a damaged clutch cable or hydraulic system, or other issues with the clutch assembly. Transmission problems: If the transmission is damaged or worn, it may not be able to shift into 1st or 2nd gear.
If your vehicle will not shift out of first gear, the problem is not the fuses. The problem could be a shift solenoid, but more than likely, you have an internal transmission issue that will require rebuilding or replacing the unit. The 1-2 shift valve may be the problem.
Transmission Fluid Low or Poor Condition – Vehicles low on transmission fluid or that are operating with worn out or contaminated fluid are likely to experience hard shift conditions. Lack of adequate lubrication within the transmission can cause several problems, including hard shifting.
Malfunctioning Brake Light Switch

The brake light switch is the main culprit for your gearshift being stuck in the mode. It`s a small sensor located on the brake pedal that prevents the car from starting if the brake pedal isn`t depressed.

A gasket near the transmission filter where it mounts to the valve body could be leaking causing the hydraulics within the transmission not to engage second gear properly. On the other hand, a shift solenoid may also be at fault. If a shift solenoid goes bad you can experience very similar symptoms.
For one reason or another, there are times were you think it might be beneficial to start off from a stop in second gear rather than first in your manual transmission car. In most cases, though, doing that will cause more wear on your clutch.
Check the Throttle Cables

Changing the fluid solves plenty of transmission issues but if the problem of automatic transmission won`t shift into 3rd gear persists, the parts you should check are the throttle cables. A defective cable with excessive slack is likely to create issues with smooth shifting of the gears.

The cause may be low engine oil or a faulty Intake CMP actuator causing a performance problem with the actuator. Both of these codes cause a computer strategy to raise line pressure causing the shifts to be harsh.
Fixing Rough Transmissions

All you have to do is add a bottle of Transmission Treatment & Leak Stopper. It`s specially designed to smooth rough shifting. As you might guess from the “leak stopper” part, Tranny Honey stops transmission leaks, so low fluid levels should no longer be a problem.

I have a model LTH130 42 inch cut mower and just installed a new elect. clutch and started mowing grass and it began to feel like it was bogging down and I stopped the engine and the belt was very hot. What is going on now?
ANSWER : Hi and welcome to FixYa, I am Kelly

See this link and locate your deck:

Make sure you have the belt routed correctly. ALSO make sure that you do not have it flipped 180 deg over the idler.

I recommend that you unhook the belt from the mower deck pulleys and try rotating the blades. A bad blade bearing can cause a belt to heat up. Of any of the blades are hard to turn by hand that blade bearing will need to be replaced. Check the idler pulley also.

If after checking the above you continue to experience a problem just respond here and I will help you.

Thanks for choosing FixYa,

When installing new drive belt on ModelYTH 1848XP how do you
get the new belt over the the electric clutch pulley.
ANSWER : Hello,
This is going to be a fun project, just kidding this is a pretty difficult job. I am glad you are asking.
The first thing is, you can’t get the belt over the clutch. You need to disconnect the battery and the two wire connector going to the clutch. Then you need to remove the colt holding the clutch on. Be carefull not to drop it, it is about 10 lbs, so be ready for it to fall off when the bolt is removed. There will be a flat washer that comes off too, just remember the order when reinstalling. That was the easy part. Now you have the drive pully on the bottom of the engine, this is going to be fun again ( just kidding, I have done…..well alot of these and they all are frustrating at one point or another), the pully just “slides” down the crankshaft. Well, it is suposed too. If it is old, or sat outside……it will probably not just “slide” off. You need to get this pully slid down because there are belt keepers stamped in the tractor frame or engine base, that wont allow you to get the belt off or put a new one on. If you use a pry bar to “help” the pully slide down, be careful not to pry too hard, the pully is soft, and will bend. If this happens the tractor will be jerky or worse.

Now after you decide you cant get it off without destroying it, and please stop just short of that. There is a way to take a short cut. Remember if you bend the pully and it is truely stuck, you will have to remove the engine and use a torch and cut it off. After that you will have to replace the lower engine oil seal too.

With the remove the engine statement, I was refering to disconnecting everything ( fuel lines, starter cable, exaust, throttle and choke cables). Now I am refering to making your belt replacement easier by lifting the engine and leaving the pully on…..only if you cant remove it.

First remove the 4 mounting bolts under the tractor securing the engine. Next use a prybar and pry the engine up, only about 2 inces just enough to remove the drive belt. Then install the new one the same way. Then reverse the process. You may have to wiggle the exaust pipe back into the muffler.

Hope this helps
