I've spent a lot of time in a rental CAT259 on multiple occasions. I was doing some brush clearing on a slope, I backed up a pretty steep hill with the mower off and nearly stalled the motor, so based on that information, wouldn't the 289 stall sooner due to it being heavier or are the hydraulics different? I probably need to consider a CAT299 instead of the 289...we don't traverse steep hills like this very often though.
I was in a CAT242D last week and I was a little disappointed in the power driving into sand and dirt piles with a 66" smooth bucket. I know it's a different machine, wheeled vs track and a little lighter, but it does have the same 74HP motor.
On the flip side, we also were using a CAT226D on the same project and that thing was a little rocket, it didn't feel underpowered at all. It has the smaller 2.2L motor.
My only real options are CAT and Deere due to dealers being minutes away and rest being much further, so I guess I need to get some time on a Cat299 and Deere 333G.
