Keeping the grass short is important in fire country.
I run a Kubota TG1860 ride-on mover, which I have kept going without resorting to buying pricey OEM parts.
The alternative belts that worked for me are a 11A0890 on the fan, B2692 on the 48″ deck, and a B57 kevlar on the clutch.
I’ve added a relay to the starter solenoid to make sure the starter motor gets 12v+ every time, otherwise it just “clicks”.
Replacing the deck bearings has proved easy enough though a bit time-consuming.
Keeping the deck going has required welding of small cracks on the outer edges.
Some day the diesel injectors and pump will need work and it will then be out of my hands, fingers crossed until then.
Can always bring the sheep and horses in when the mower is down and grass is growing.
