Just bought my first skidsteer, a restored 610. The guy finds them and rebuilds them for a living so he rebuilds the engine, puts in new hoses, ect. Already finding a lot of uses but was wondering if there is anything to look out for with these older machines. someone had told me if you run them in the cold it can create some condensation in the engine so you have to replace the oil more frequently in the winter. any input would help thanks. here is a pic: http://image20.webshots.com/20/9/43/64/2298943640066221768yijgEE_fs.jpg?track_pagetag=/page/photo/rides/motorsports&track_action=/Owner/ViewActions/FullSize
