For those looking for an upper radiator hose for a Bolens/iseki TS1910, i found a cheap alternative. i found the 2AA1 motor was put in Bobcats. That part is #A-6576028 and $6.00. Ordered through AI Products. This hose has different diameters at either end and is molded - no generic hose would work.
This new hose was a bit long but i just trimmed 1/2" off either end. The only oem part i could find was $88.00 from southern global.
