Draft horses showing their strength, bluegrass musicians twanging out tunes and women flinging cast-iron skillets are all on the schedule for Saturday’s Harvest Festival, from 10 a.m. to 3 p.m. at the Martha’s Vineyard Agricultural Society grounds and hall in West Tisbury. The event is free.

Last held in 2017 as the Living Local Harvest Festival, the autumn event had grown over 18 years to an all-day combination of fair, farming symposium and music festival, concluding with a dinner and barn dance.

This year, the Ag Society returns to its roots with a shorter festival centered on some of the most popular activities from its Agricultural Fair in August.

The All Island Draft Horse Show, from 10 a.m. to 1 p.m., includes demonstrations of equitation, cart and wagon obstacle courses and barrel racing, among other feats of equine power and skill.

Registration closes Friday for the Women’s Skillet Toss — a perennial attraction at the summer fair — from noon to 3 p.m. in the pulling ring.

The Pickpocket Bluegrass Band plays from noon to 2 p.m., and lunch will be available from Goldie’s Rotisserie food truck.

A talk on controlled environment agriculture — growing plants year-round with weather protection — begins at 10:30 a.m. in the hall.

The antique power museum will be open, and other festival activities include the West Tisbury Farmers’ Market, fiber and spinning demonstrations, tractor and wagon rides, cider pressing, felt crafting, face painting, pumpkin carving and farm animals.

Island Grown Initiative, the Farm Institute, the MV Hunt Club and the eighth-grade class at the Martha’s Vineyard Public Charter School are among the organizations taking part in the festival.
