Is that old 950 straight frame?
I used to run a 966C, the thing was a beast. It could do some interesting things like climb out of some decent sized (straight walled) sub cuts
Cat Loaders earned that good reputation, they are the best in the business. I've tried Volvo and Deere and they just didn't feel right...
I'm not really biased to Cat with everything, only loaders.
For hoes, I've run Deere, Komatsu and Cat and I think they're all great in different ways.
For Rock trucks I like the Volvos.
I also tried out a John Deere 750 dozer this summer and thought it was great...
