Hi Andrew I haven't had anything to do with the 910's The R series are very simple to work on and you can get at everything. The Greenfields can be difficult to work on because everything is nut and bolted together and sometimes the nuts are near impossible to get to. If they had used captive nuts on all the difficult to get to nuts they would be much easier to work on. Their steering set up on the earlier ones leaves a lot to be desired, they improved that on the Evolution models. All these mowers have their problem bits
