im no expert. so I asked google.
gear ratios and crawl ratio explained - 4 lo or 4LO also 4WD low range
and this lovely gem:
Crawl ratio - Wikipedia, the free encyclopedia
your clutch/idle/stall is not specifically related to the crawl ratio. Crawl ratio is about gearing.
Now... "most" people here will agree it is easier to climb / crawl with an automatic transmission.
How ever there are add-ons such as a hand throttle

Hand Throttle
That can make the job "easier" to clutch/brake/acceleration while crawling.
Does this answer your question?
