Q:

MTD Lawn tractor slipping out of gear

A:

I understand that your lawn tractor is slipping out of gear. I have taken some time to research your question here on the Manage My Life website and I noticed that someone else had asked a similar question with a posted response from an expert. I attached the link below if you are interested in viewing. I hope the link that I provided is helpful. Have a great day.

If the transmission is physically coming out of gear (like moving the shifter) then there is something wrong internally on the transmission. If it just runs ahead, it may just be speeding past the gear speed. If that's the case there's not much that can be done about it other than to stay off the hill. With this being a variable drive system on this tractor it could even be one of the drive belts causing the issue.

Check the transmission belts to make sure they are not worn. If they are not, run the machine around on level ground and see how well the machines goes from fast to slow as it's possible that the variable speed pulley is sticking as this would allow the transmission to speed past the setting.

Thank you for using Manage My Life!

Thanks Wade - I did as you suggested and the mower works fine on flat ground. Then I put it up on jack stands and put it in gear and turned both wheels forward and it slips and makes the same noise as when I am riding it and it slips. It sounds like gears are slipping and making a metal on metal noise. If I turn the wheels backwards it does not slip and seems fine. Is it a differential on the rear axle or is that the transmission? The noise is coming from there. Thanks, Phil

A:

The transmission and differential are all one unit on this machine (and most lawn tractors). What you're describing is pointing towards there being a problem within the transmission. If there is pressure on the transmission maybe it's hopping gears. It wouldn't necessarily do that on level ground because the pressure (load) is not that same as when on a hill.

You may be right. I was looking and that transmission sells for around $300. That's pretty high in the world of tractor transmissions considering how basic that one is.

Hi Wade - Me again! Well I bought a new mower but I kept the old one and found the problem in the transmission. One side of the drive gear was worn and I was able to flip it around and use the other edge for forward. I will slip in reverse but that is not a problem. So I have been using it for the last couple of months and now I have slowly lost 1st speed and now sometimes 2nd speed. I'm not sure if it's a belt or an adjustment. Any ideas on the cause?

A:

Phil, To determine if it is a problem with the belt I recommend pulling back on the brake pedal when it starts slipping. If the tractor stops slipping, the problem is in the belt. First, inspect the belts to be sure they are not glazed over or burnt. If they are, they should be replaced. If the belts look ok, make sure all the idlers are moving freely and the springs are intact. If all of those look fine, please reply below with the complete model number. I will be happy to assist you further. The reason is I show this model to be a vari drive unit and it sounds as if you have a manual transaxle.

Hi Mark, It is a variable speed model - Mod# 13AH762F752. Since posting the qusetion, I have inspected the belts and they are a bit worn. I will be replacing them. I also checked tourque converter and tension springs and they are fine. I used a belt dressing on the drive belts and put it all back together and it seems to be working ok but I plan on mowing the front couple of acres today and I will find out for sure. One section of the shift/brake linkage is a control rod that has a threaded end that allows for adjustment. Is this something that can used to correct belt wear?

A:

Phil, You can adjust the belts a little with the threaded rod if the belts are stretched. Otherwise the belt is tensioned by the spring. If the idler assembly is binding the spring may not pulling it back enough to tighten the belt. Pease let me know what you find.
