Dual Hydro pulling left!?

Hello, I am new to Lawnsite and I am looking for some help with my dual hydro. I have a MTD Pro/Cub Cadet Commercial that is pulling to the left when both levers are even. I have to adjust the levers to take the pull to the left out. I would like to fix this so I can just mow instead of trying to adjust the levers to get the thing to mow straight. Thanks

Don't forget to check the air pressure in the tires. A low left tire, will make it pull to the left.

how bad to the left? does the lh hydro feel gushy or not as responsive? hold a hill? or is everything fine it just pulls to the left.

air pressure should not be equal in each tire, you have to wrap a tape measure around them and make sure they are the same size around. the air pressures may be different when you are thru. there should be an adjustment on the hydro motors that allow you to make the machine track strait. if it is not the tires i would try that next.

pulls pretty bad I am fighting with it all the time to get it to go straight. when you say "hold a hill" do you mean just let it sit as if i were going up a hill?

The right hand control does feel a little soft. when I pull the left side it seems to be more aggressive. If a bagger were used quite a bit could that cause the pump to weaken? I am not sure but I think there is a motor and a pump. I will check later to day. Thanks for the help.

if you have a system with a filter change it. you need to check the dump valves to make sure they are either engaged or tightened. if the unit has two big units one for each tire, with no hydrolic lines going anywhere then they are all one peice, which gives you less variables for trouble shooting... make sure that the input pulley set screws are tight. hydrolic componets usually carry a decent warranty i would check into that also

Dump valve is probably loose. They are to open when you need to push a dead mower. They should be located on the pumps and will have either a t handle ot a large nut on top of the valve. Your manual should refer to them and show you where they are.
