I bought a used 2004 Grasshopper 722D for $2500 about ten years ago. It has done a great job mowing the 8 or so acres of grass I have
A couple years back, the original Kubota radiator blew out and the engine overheated. I didn't notice immediately, as the wind was in my face and the engine is behind me.
Replaced the radiator for ~$800. Engine running terribly. Tried rebuilding the engine, still no good. Bought a rebuilt engine for ~$5000. Found out about the cracked cylinder head when the rebuilder tore the core down.
Last week, while mowing, noticed the teperature guage rising. Checked the radiator - coolant oozing from the rubber seal between the top tank and the core. Parked the machine instantly.
Checked the Grasshopper parts place I get stuff from - new original radiator is $950. Checked the local Grasshopper dealer - $1050, and a week wait.
Searched online - found Radiator Supply House in Sweet Home, Oregon. All aluminum repalcement radiator. $1450 shipped. Ordered one.
Installed it yesterday. Had to modify the top radiator support and the fan shroud a bit to clear the radiator, but otherwise, slipped right in. Engine runs nice and cool now.
The grass had grown long enough that I had to use my big tractor to mow most of the lawn - Grasshopper was getting bogged down.
At least the lawn is back under control. Even with all I've spent over the years for parts and maintenance, I still got a deal - new Grasshopper mowers run around $18K.
