The gear with the more number of teeth is bigger.
I have seen that his resting pulse is abnormally low, around 32-34
Usually a high gear is better in snow because it does not slip as easy.
if it has a high low trans then it probably is in the middle of high and low!
this is the lever that enables high and low gear for 4wd.
I run in Hi gear
Low RPM. Gear is too high for travel speed
High gear ratios, 273,373,340 Low ratios, any thing starting with the #4 and up is a low gear ratio. 410 411 456 488 556 and up.
A double over bicycle will have two gears for the chain and it allows for easier pedaling up and down hills. When you are in a low gear, you will find that having the chain on the smaller gear will work better than having it on the large gear, which should be reserved for the high gear.
I'm guessing the low gear is for towing or climbing The high gear is for normal driving on road, the low gear when engaged lowers all the normal gears for driving cross country over severe terrain, something that very, very, few drivers of range rovers ever do.
Cooling fan clutch could be seized.
In motor-driven vehicles it's often best to use a high gear, as it reduces the likelihood of the wheels spinning loose. For a bicycle it's often better to use a low gear, as it makes it easier for the rider to control the power.
