Anybody currently running these? I picked up two 48"s yesterday, and have been going through them, and these appear so far to be a very well built mowers. I know they sold out to Worldlawn or whatever recently. Just wondering if anyone has been buying parts and such recently, and if the transactions were smooth. Also this is my first wheel motor/pump combo machine, and looking at the hydro system it seems like it may be difficult to get all the fluid drained and the air out of the system with the way it's set up. Any tips? The hydro oil appears to have been exposed to some moisture/condensation while sitting for a bit and needs changed. I guess I got spoiled with the integrated pump/motor units and the easy maintenance. Thanks.
