I hate to sound like the safety police, but I am concerned about this idea. Wheeled skidsteers are not great on slopes. Their short wheelbase makes them tippy. Tracked skidsteers do good on hills, however their low ground pressure also makes them prone to sliding on wet (freshly cut) grass. A 45 degree hill is damn steep, If it has a nice flat area to run out on after sliding down then I would not see a problem in trying one. However sliding down into a pond is dangerous. A skidsteer only has two egress points, both are easily blocked if the machine is upside down sinking into the mud. I have spent lots of time mowing hills in lots of equipment. I have slid down lots of hills too in everything from a zeroturn to a skidsteer to a backhoe. Have you ever been in a 2wd tractor and seen one wheel turning backwards as you go down a hill? Steering brakes are ment to allow you to steer up hill since the front is no longer terra bound. I have lots of experience with hills, but hills with water at the bottom require additional respect.
I hate to sound like a worry wart, but a skidsteer is a great way to multiply your chances of underwater entrapment.
Also is this a true 45 degree slope? If its 35 degrees and smooth then the options really open up for equipment. Its amazing how much difference 10 degrees makes.
