Cub Cadet RZT s 42 When raising the deck, the left side hangs low. I have leveled the deck using the 'adjustment' but has no effect on the deck hanging low

Lubricate all the linkages with spray lubricant.

and have you tried ebay?.

There are a couple of things which can cause this, one being the right and left steering gear may be worn and slipped the teeth. That is the most likely cause. The other could be the cause which would allow the teeth to slip. That would be the steering gear bushing. Hope this will help.

You first need to find out why this safety feature is being triggered rather than bypassing it for your safety.

take plugs out try turn over by hand or with the starter

you will need to take it to shop it is complicated to do

Your seering linkage needs adjusted. I try is first.
Find a free service manual to show you how.

First, check the level of the hydraulic fluid (usually the dipstick is right inside the fill cap, and you just raise the seat to access it). If it's low, fill 'er up with the right fluid.

If that's OK, test if the lack of 'pull' affects the left wheel in both forward and reverse -- try going up a hill forward, and backing up it in reverse. If it affects both directions, maybe you will be lucky -- the problem could be that the bypass for the left hydraulic motor has opened somehow. (The bypass is used to let you push the mower by hand in case of an engine failure, etc.) So look for a fat-headed bolt sticking out of the left hydraulic motor. Check that it's tight -- rotate it just like you would tighten a bolt, clockwise. If it wasn't tight, that may be the problem; just tighten it and try the mower.

If this doesn't resolve it, you probably have a problem in the hydraulic valves, hoses, or motor, and a trip to the dealer is needed. Probably won't be cheap, sorry my friend. Good luck, and please rate if this was helpful, thanks!
