LT2 NR92 drive problem

[Kestrel]

It's the hydrostatic version. I'm not sure if this model number is a UK variation only, but I have a drive problem.

After the tractor has been in park, even if only for a couple of minutes, when I disengage the brake and press the peddle to go forwards, I can feel slight juddering and hear the belt spin, but it don't move. Same applies to reverse also. If I pump the pedal either forwards or reverse, it does start moving after 5 seconds or so.

I think it could either be a stuck brake pad or perhaps a slack belt, however once it's moving, I have no issues with speed.

That tractor was bought brand new from a registered cub cadet dealership last month. I would take it back to the dealer for them to take a look, but it will cost me the best part of £50 to do this due to living on an island and needing to use a ferry. If I can, I would rather try and fix it myself and save my money.

Would this void my warranty? I have worked on lawn tractors before, but never a hydrostatic version. Before I start stripping all the guards off the cutting deck, can anybody advise on where exactly I should be looking on this machine please? Is it much different to a transmatic lawn tractor underneath?

First, welcome to OCC.....

It would appear that the LT2 is an export model.

From the sound of things, I think you are right. I would venture to say something needs lubricating, or some adjustment needs to be made.

How much did the mower cost? I might ask the dealer could they send someone out to adjust it.

Thanks for the welcome.

Mower cost £2200. Dealer won't send somebody out. Because it came with 3 year warranty, I asked them when I bought it and they said I would have to return it to them for any repairs. If it is something I could remedy myself, I'd rather save my money if possible.

So do you think it's most likely the brake sticking or is it the belt too loose? If I do the work myself, will I void my warranty?

I tried pulling up a Parts Diagram at the Cub Cadet site here in the States. It stated no such model found. So, I can only venture and educated guess. It "sounds" like the brake is hanging up, perhaps not allowing the belt to travel freely, hence the noise from the belt.

If I do the work myself, will I void my warranty?

I do not know the laws in Scotland, but here in the States, if a company finds out that and "unauthorized" repair was done, they may go as far as voiding the warranty, depending on the situation and extent of repairs.

Thank you for getting back to me.
I will have a look at the brakes this weekend and see if that is the problem. If I just need to add a bit of grease or tighten a nut, I will probably get away with doing it myself. But if that doesn't help, I think I'm going to have to bite the bullet and take it back because I don't want to invalidate a 3 year warranty on a brand new mower.
I have had a look around on cub cadet sites and it is advised to check and adjust/tighten nuts periodically if they come loose from vibration. I can't see how this repair would be much different. I don't understand why a machine this new would have loosened its nuts though, unless they weren't tight enough to begin with. It's been running less than 15 hours in total.

[R Bedell]

Anything is possible, but I am guessing more along the lines of a Linkage Rod that is out of adjustment, or needs lubrication.

I was on a European Site and they are asking for a 11 digit model number. What is your Model Number as seen on the Chassis Tag..???

[Kestrel]

I don't know, I'll have a look tomorrow and let you know if that's okay?

[R Bedell]

No problem.
