I can't find a block heater to fit a HST 22! ID measures 15/16 on bottom radiator hose, I did purchase a Katz oil pan heater and it does make a difference on cranking speed for a quicker start!
Leadfoot64 I got a 2016 emax HST 22, Brand new 70+ hrs , I started to run my mid mount finish mower! I never had to run the engine over 2500 rpms, so when cutting heavy grass is when I noticed it! Bought it to the dealer and it was a known problem with the fuel injection pump! so they removed...
