Yep, there were industrial 430s. The only difference from an industrial 430 and an agricultural 430 was the pretty yellow paint job. A supposed "industrial" 430 could even have the normal green and yellow paint. Of course-other paint schemes were avaliable at extra cost. There seems to be no special designation on the serial number plate either.
Actually, there was ONE special industrial 430, a forklift! To learn more, go here.
The industrial models were based on the 430U "Utility", and the 430C "Crawler".
