Hey everybody, first post , love the forum. I just bought a 310-8 tractor ( my second Wheel Horse) ( my other is a B-80)...........When checking fluids, I found there was no gear lube on the trend dipstick. BUT, when I took out the square plug on the left side of the tranny lube came right up out of the hole. Is there another place you fill these trannies from to get the level up the dipstick OR do you fill until its level with the angled fill hole on the left?
