Two fire engines were called to the incident in Ditton Priors, near Bridgnorth, to extinguish the fire.
An operations officer from Shropshire Fire and Rescue was also in attendance.
Crews from Bridgnorth Fire Station and Much Wenlock Fire Station used breathing apparatus and water hoses to stop the flames.
A short extension ladder and thermal imaging camera to check to ensure the fire had been completely extinguished was also used.
The incident happened at around 1.30pm today.
A spokesperson for the service said the blaze destroyed 50 per cent of the combine.
"At 1.36pm on Wednesday, 16 August, Shropshire Fire and Rescue Service fire control received a call reporting a fire classified as combine harvester fire in Ditton Priors.
"Two fire appliances were mobilised from Bridgnorth and Much Wenlock and an operations officer was in attendance. One combined harvester was 50 per cent destroyed by fire."
It comes just days after firefighters were called to a combine harvester fire elsewhere in the county.
Another combine was on fire – along with an acre of crop field – in Cheswell Wood in Lilleshall, Newport on Saturday.
Crews from Newport and Wellington Fire Station attended.
Firefighters used beaters to extinguish the blaze and stop it from spreading just before 4.20pm.
Both incidents were resolved by Shropshire Fire and Rescue within around half an hour to 40 minutes.
