Testing a Cat 299D2 skid loader in Deep snow

What happens here

The video critically assesses the operator's visibility from inside the cab. The presenter points out that while CAT attempted to improve forward visibility by narrowing the cab, a substantial horizontal cross-bar at the rear significantly obstructs the view. This issue is partially compensated by a standard rearview camera. The discussion also highlights the machine's 'butt-heavy' design (weight concentrated at the rear) which, while increasing front lifting capacity, can hinder maneuverability in tight working environments and increase the risk of rear collision.

Goal: Identify and evaluate critical design aspects affecting operator safety and maneuverability.

What they say

Hide

but I know we've used the track like this before and it handles much better than the constructions type with the big logs yeah you think no it grips a lot better yeah the big lugs are no good the rear visibility is really poor but they have a rear video camera and it really helps so that's one of my pet peeves on all caps is the visibility just sucks so they've limited the calf size right here so you can see where they've skinny this up in an attempt but then they blocked it with this big honkin bar over the back which just makes zero sense to me but I guess the engineers they can't know more than I do so as an operator I just don't like it so from this point I look at this point look at all the mass so the way to this machine is all back here meaning that this machine's back heavy now that gives you the ability to lift more in the front optimally but if you don't have a big load on the back you got this big fat booty hanging out on the rear end and especially if you're working in tight areas that's a lot of extra mass that you may not want so that's just something to take into consideration every machine is designed a little bit different but once you actually get in it and you start swinging this big tail fin around and maybe you're working on retaining walls or around houses or if you're working out in the woods that's a lot of mass to be clocking up against the side of stuff that doesn't want to be clumped up against the side of so that's something else we're gonna be taking a look at while we run this thing through the woods today
