Dash throttle control

[Bretto]

I know the saying there is no dumb questions, but I feel dumb asking. Was the throttle control used to bring the engine rpm's up to run radio equipment or just what? I know you wouldnt want to use it at a cruise control, that wouldnt be safe.

MY JOHN DEERE HAS A SIMILAR SET-UP THAT I ALWAYS USE
WHEN IM ON ROUGH GROUND TO PREVENT LURCHING..

Makes starting a whole lot easier too. Cruise control

Throttles were also very helpful when using pto driven equipment such as a winch or flat belt drive pulley. One variant even put a Ferguson three-point hitch on the back of the jeep so it could be used to pull a plow. When creeping along in 4WD-Lo the throttle makes a very good cruise control.

If we're talking agri-jeeps, many also had a centrifugal governor to aid when farming.

Drive one 700 miles in two days and you will find another use for a hand throttle!! John

Same for parades where the pace is a slow walking rate. You can gear down the jeep and set the throttle to keep from using the clutch so much.

Standard Canadian Army procedure involved starting the engine and using the throttle lock on high until she warmed up from what I understand...

[Bretto]

So no official use other than convenience it sounds like. I was thinking there was some formal use for it.

Well.....here's what it says in the TM9-8014......sounds like the starting and warm-up procedures should be considered the "official" use...

Don't overlook the use of radios on the jeep. If the jeep was stationary the hand throttle would be pulled out to maintain a charge rate that would keep the batteries charged and handle the radios when transmitting.

The ratchet thingamajig on my hand throttle is worn to the point where it won't hold a position. I think it may not even be correct, as it is a T-handle and the manuals show a round knob (P/N 801683). Is the correct version just a friction type like a choke cable?

Edit/Update: I based the "round knob" comment above on illustrations in the ORD 9 parts manual, but in the "M38 Reference Guide" (Miller), on p. 125 a T-handle is shown, so the one I have is probably correct after all. Any ideas on getting the ratchet to work better?
