The old man grumbled and groaned as he realised there was more work to be done. Always more work. Always more obstacles and intrusions and hazards in this blasted place. Oh well, it's not like he had anything better to do. He pranced to the side of the bay and fiddled with a tablet. He adjusted the vehicle dock from the device, the wheel clamps locked the harvester in place and raised it a few feet so he could access the undercarriage. He remounted the auto-dolly, this time on his back. His shoulder light flicked on automatically when it senses the darkness. He made sure to stay away from the leak but craned his neck back to get a look. Some loathsome critter was jammed up. It's fur was scorched and the combination of burnt hydraulic fluid and singed fur and rotten scorched flesh was a vile stench. 

He removed himself from the undercarriage and slowly clawed his way back onto his feet. He mumbled something about 'the fucking rats' as he sidled up to one of the pocket printers. He thumbed in a string of codes and the high-tech box spat out a thick plastic containment bag. He covered one of his back-mounted claws with the bag and opened the drawer with his respirator in. It was a pretty Gucci piece of kit, he'd modified one of the standard respirators to his liking. With his mask on and his claw covered with a bag he went back under the harvester again and used his cybernetic manipulator to grasp the carcass with the bag. After some fumbling it dislodge and he felt the weight shift into his grasp. He steeled his stomach and held back a gag. At least he couldn't smell it through his mask. He wheeled himself back out. He would inspect the piping closer in a moment. 

It was feasible that the automated routines could replace it. But that would probably take a few days and put the harvesting schedules behind. He would do it himself. But first he stood up and used his spare grasper to safely contain the corpse in the sample bag. He held the enclosed specimen in front of his face and examined it with a puzzled look on his face. He didn't think the dome was designed to foster mutant Hyrax, so this was alarming. 

Arthur held the specimen bag up to a camera and commanded Holiday, "Urgent message for the scientists, priority message for Kaplan. Send them this camera feed with the following message: Just found this lodged in our damaged harvester. There's all the chances it has been here for some time. Unknown. I'll need this sample collected for analysis from the Cauldron. End message." 

He followed this up with a short string of expletives. "Bad luck, Holiday. Looks like we have a rat problem." He groaned again, setting the sample down obviously on one of the clear and prominent counters. He then returned to the vehicle's undercarriage and began busily fiddling the pressure valves and his pipe cutters.
