The 755, 855 and 955 have 2 sets of front lights, plus flashers.
There are 2 55w rectangular lights mounted in the fenders, just to the side of your knees. These lights are bright, provide great visibility, but do bounce off the loader uprights. They provide fantastic visibility of your mower deck if you choose to mow at night - something I haven't seen on any other tractor.
Also - there are 3 smaller lights integrated into a light bar in the front of the hood. These are not as bright as the side lights, but provide good forward lighting. As with any tractor, they can be blocked by the loader bucket when it at the wrong height.
I'm satisfied with the lighting on my 855. I think it is better than that I've seen on a lot of other models.
Overall the 755 is a good tractor. All are 2 spd hydro. They were available in 2wd and 4wd - look for 4wd. Believe power steering was standard - but may only have been on the 4wd versions. Independent mid and rear PTO std.
Takes the 70 loader - which was also used on the 770 / 790 tractors at one time.
800 hours is not a lot for these machines - but general care and maintenance can make a big difference. Check for any signs of abuse or leakage.
