    3720 How to install new hydraulic arms to lift belly mower deck

    Hi All, we had our John Deer 3720 looked at, because the PTO was rubbing on the hydraulic arms lifting and lowering the belly mower deck (Iron7, 72" deck). The servcie professional said that the hydraulic arms are busted up and need to be replaced. Is that an easy repair to do ourselves? Are there instructions anywhere on how to do that? Is there a good place to buy these parts?

    Sorry for all the questions, but if we are not able to repair it ourselves we would have to invest into a zero turn mower instead.

    Have a happy day!

    Can you possibly take some photos of the part that is broken? I'm sure we can probably help but less folks use a belly mower on the 3-series compared to the smaller tractors. So less "experience pool" to pull from. ;-)
