Well the last 3 mornings have been frosty,so I have the B7100 hst,the 4' snowblower.One thing I would like is a block heater or some kind of engine heater.My garage is unheated and it gets darn cold were I live.I think those 4:30 am start ups would be helped by this.Any suggestions? I saw a Kubota block heater listed for this tractor on line,I think it might be a core plug replacement type,sure hate to knock one out if I don't have to.
