If I remember correctly, they do.
What’s the issue?

They do. It's a two stage job (dual clutch) on the pedal like MF135. There is external adjustment to set it up. Ours, on our cyclone beet harvester skid unit, has stuck itself to the flywheel through underuse so have left it alone as the machine uses a belt clutch out the back to start and stop.
If adjustment of the pedal lever mechanism externally won't sort it out then it's probably a split the tractor job to sort it out properly, (if it won't break free by driving a big implement with the pedal down).
A DB expert could probably offer more accurate advice, but that was my experience.

Can you feel the second stage on the pedal? Our 990 lost the second stage somehow and I gad to heat the adjusters to get them moving to restore the second stage. By then the flipping plate was stuck solid to flywheel or pressure plate so a session on the slurry stirrer sorted it!!

Its a long time 30 years since I had one ( sadly ) but I seem to remember that if you have a badly worn main clutch it can affect the pto clutch.
They are not difficult to sort though. Splitting is easy unless it is the later q cab, I never did one of those.
May get more info on the DBTC website and info for parts, hopefully just wear plates and new thrust washer bearing.
Ps if this is a stockmans tractor ( most likely ) it probably just needs the crud below the pedal removed to restore operation

Laycock clutch, nowhere near as good as the earlier Borg and Beck units Browns used to fit.

It is the Q cab model !! Currently need to stop engine to engage pto.
I suspect the pto plate is stuck or rusted up.
Sounds like i need to try rotavator on it and see if it can be freed with clutch down !
It has never been a scraper tractor, it came from a welsh county council with low hours and was restored a few years ago. At only 2200hours the engine and clutch were not touched....but maybe we should have looked !

If it’s the q cab does it not have the hand clutch? Or was that only the later 4 cyl models like the 995 or 996.

996 and above had the hand clutch

Are you sure you are getting full travel on the pedal. I have a horrible feeling that clutch is self adjusting, although I believe there is an inspection cover underneath where you can very carefully make some difference.
A I said previously the DBTC site is best for this tractor and advice

Are you sure?
Hand clutch appeared in the later series when some tractors were designated 995 and those withhand clutch 996
However all tractors sold in many countries were designated 995 to avoid confusion.
Hand clutch version was 4 inches longer

Yes I'm sure, I've seen one, we t to look at it with a mate, he wanted to buy it, but desired it was not original/genuine, I think it was a 4wd, only later did he find out how rare and valuable it really was, I'm fairly sure it ended up in the db mesuem
@Selectamatic will know I'm sure

Wont have worked hard then!!
Um, i cant think of the tractor, but a 990 4WD is rare in its self. Production 990's did not have a hand clutch, 996's upwards...

950’s had a hand clutch at the rear, which could be operated in a couple of ways. Firstly for overload protection combined with a spring loaded top link ( too much load on the link would trip the clutch out ) secondly as a hand clutch for use as such a saw bench.
Never saw similar on a 990 though

@multi power is correct about some 990s having a hand clutch. It wasn't standard spec and it might not have been listed as a factory option but there are some about. When we bought our 996 the dealer had a 990 with hand clutch for sale

I'm pretty sure it was some kind of a proto type

Possibly, or a special build. Either way it's rare. One I saw was 2wd

The first production tractor with the hand clutch was the 1200 from Jan 1967, I can imagine the 990 with hand clutch was maybe the protypes for the 996 which came along Jan 1971.
The 950 did have the hand clutch at the rear as an optional fitment, it was useful as @Exfarmer points out, but it was designed as a safety feature to stop the tractor from being pulled over backwards or to keep the front wheels on the ground.
Although now having looked at the parts book it's possible it was standard but removed by users, I know off 2 which never had it fitted.
