low gear

Ok I’m probably wasting some time but wanted to get some feed back but I got my grizz about 3weeks ago now and haven’t rode it much due to me installing a snorkel but my low gear doesn’t seem low I tried to pull out a bush from the ground yesterday and had it in 4wd and in low and it wouldn’t spin a tire now it was revving up so I’m pretty sure no issue with power but I’m thinking linkage because I was playing in the ditch earlier and it slipped out of gear so my question is is low gear suppose to b low or just not run as fast as high gear
