I have a 2017 model but same model number, If the dealer will sell and install the heated grips for $100 I would have them do it, You can't even buy the Ariens grips for much less so better to have them put them on. And for gravel I would get a set of ARMORskids no matter the blower you get, They have more surface to help them from digging into the gravel.
Sno-Tek Modded, 15"X-Track tires (Now has same X-Track tires but 13"x4" for better fit), 254cc engine LED light and hand warmers.
Snapper 6/22 sold but not forgotten. Was my first.
Ariens ST1027LE workhorse and going strong.
New 2017 Ariens Deluxe completely rebuilt after losing a fight with a forklift.
