    Compression issue after rebuild

    someone in the distant past very wisely said: For an internal combustion engine to run it must have fuel, compression, and a spark at the right time. He also said if all these were present it was beyond his expertise to repair. Apparently you do not have a spark at the right time due to cam...

    2003 721D

    I worry about the transmissions on the 721D since they are no longer made. One side of mine is getting weak and if a replacement is nonexistent what must I do to save the machine?

    9561 deck

    Anew lift arm for the 9561 is around $630.00 with a 2 month wait for fabrication. I found out from Grasshopper there is an arm with the hook for a 72 inch deck that can be welded on to replace the broken hook. About $80.00 shipped so I went that route. I forgot the part number but in a week when...

    9561 deck

    I broke my lift arm on my 9561 front deck part number 603559. I welded it but it broke again. I would like to buy a used part if possible. A new one is expensive. I would buy an old deck for the parts if I could find one.

    721D Starts but doesn't run... Fuel solenoid problem.

    The fuel hold on voltage comes from the switch interlock module and it costs over $62.00 so I will just keep using a manual strap when mowing!!!!!

    721D Starts but doesn't run... Fuel solenoid problem.

    I also have that problem. It is the holding voltage that holds the fuel solenoid open while running. I don't know where it comes from or I would fix the problem. Now I just have a strap around the fuel solenoid then start it and leave it connected while mowing then remove it when I stop...

    Access to underside

    I have a 2003 721D and have started to develop some leaks. I am not as agile as I once was so I need suggestions as to how to get underneath. I started to use my front loader but decided that was not a wise thing to do. I even thought of building a service ramp like old auto grease ramp. I have...

    Hydro faults

    I have a RZT 50 Troy bilt and after about 30 minutes of use the right hydro just quits and growls at me. I have to let it rest 30 minutes then take it to the house after it starts working again. I have heard from many people that is a common fault with the MTD made mowers. I have checked for...

    721D RPM change

    I have a 2004 721D that the RPM drops after a quick turn. It doesn't stop but just drops down then recovers quickly. The tank can be low or full and the add on clear line filter is nearly full. What will cause the RPM change?

    belt size

    I own a 2003 721D and the hydro belts shucked on me out in the vineyard. I need the size of the 38193 belt so I might get a local auto supply store replacement so I can get the mower out of the field quickly. I can get back ups from Grasshopper later. I just need some replacements now. I...
