17.5 hp 42 in. Deck Lawn Tractor – CA Model

My 15 year old Craftsman model 917.252590 with auto transmission moves extremely slow when advancing the speed lever forward. The tractors forward movement will stall out & stop unless the speed control lever is pulled back to neutral & them moved slightly forward. The drive belt was replaced about 18 months ago & is good condition. The Kohler engine is fine, the tractor just will not pull.
Experienced gardeners share their insights in answering this question :
Check the adjustment from the lever to the transaxle, if the linkage is ok the transaxle may be suffering from age and has leaking internal seals.

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 :

The reasons why mower is not moving forward or reverse is that the battery is dead, or due to clogged fuel line. Additionally, malfunctioning transmission, or a broken drive belt, also a faulty spark plug, even when friction wheel isn`t in contact with the friction plate, or damaged Tires.
Failure of any mechanical component, a broken hose, or clogged filter will cause tractor hydrostatic transmission problems. But the most common issue will be the oil itself. In the transmission section of your operator`s manual, you`ll find a section that covers oil viscosity.
If your lawn mower turns on but won`t move, there could be a number of potential causes. The most common issues include a broken or damaged belt, a clogged discharge chute, a broken or damaged drive cable, or a damaged or clogged transmission.
There are a few common causes as to why a Craftsman riding lawn mower may be going slower than it should, ranging from a worn drive belt, clogged air filter, or even a loose or missing blade. Troubleshooting these issues can help you get your lawn mower back to its normal speed.
Check the drive belt that is located just above the mower deck. Follow the belt as it wraps around the deck and to pulleys under the engine and the rear tires. Make sure the belt is secured to the pulleys, because if it is not, then the belt (and thus the mower) will not move. If the belt looks broken, replace it.
Over time, dirt, debris and other tiny particles can accumulate in the transmission fluid, affecting its fluid properties. This can cause the vehicle to die when you shift into drive or reverse, allow a loss of power, transmission slip, rough shifts or even prevent the vehicle from shifting into gear at all.
Check your grass bag isn`t clogged

If the lining of your grass bag is clogged with old grass you should clean it using a jet wash, air line or simply a brush and water. Once clean the air should flow through the grass bag more efficiently and improve the grass collection.

Riding mower not going forward or reverse could be caused by a number of issues. The most common cause is a stuck or broken clutch, which prevents the mower from moving. Other causes could include a broken or disconnected drive belt, damaged transmission, or a problem with the mower`s starter or ignition system.
