Murray lawn tractor is slow moving.
Does the automatic transaxle need oil? What is 5" high black rubber tube sticking up out of the transaxle?
Welcome to JUST ANSWER small engines, let me try to help you !! Do you have the full model number of the unit? example 304567X92a
The tube is the vent tube for the transaxle.
You could try adding a little 20W50 through the tube. Have you removed the linkage at the transmission and checked to see you are getting full travel with the foot control?
Yes, unless you have a leak, it is not likely to need fluid.
Foot control (speed, forward and reverse) linkage to transmission appears to be allowing full travel. I did not "remove" the linkage, but observed as I operated the foot pedal. I have the deck off and will leave it off for now. I have backed off the brake, probably too far, but that should insure that that isn't the problem.
I need to re-install the battery, then try moving/driving and re-adjust the linkage to see if there has been any improvement. I have other chores to do this morning, but will get back to you later.
Ok, but I would remove the linkage from the pedal, simple enough to do and insure it is getting full travel. Just a little at the far end makes big difference.
Removed linkage and it appears that it will move fully in both directions. Reinstalled to foot pedal linkage, went for a test drive to check forward speed. Readjusted linkage. Out for another test drive all of a sudden a lot of oil leaking out of the engine! A totally different and unrelated problem! Back into the garage. Oil filter cap (there is no oil filter on this model B&S engine) is leaking bad.
Took off the cap, it's all aluminum and had cracked. Went on-line and ordered a new cap and gasket. So tractor won't be moving until I get the parts and install. So I won't know if I have/can fix the original problem, the slow forward speed. I won't keep you hanging for a week or two until I get parts. Do automatic transaxles go "bad"? Still work, but not efficiently or slip?
Yes they do go bad, they get internal wear and the pump is not as efficient as it was new and they just get weaker and weaker.
