The peddle took me a little while to get used to, now I like it. Big mistake placing your foot on the top and "rocking" back and forth. Its just way too uncomfortable for anyone over 5ft tall. Use your toe on the forward end and rest your heal on the floor board. For reverse, lift your foot and place your toes where your heal was, and heal on the rear part of the peddle. Yes, its more movement of your leg, but way easier to control.
While I agree that the split brakes are useless on these models unless you have cruise control, they actually don't need them. I used the split brakes on my 770 a lot, but the 2501 seems to turn better. With a 5ft mower on the back, I think you'll be able to get to everything you need to.
I do like to use the split brakes as a "locker" though, and apply power to the rear wheel of my choice. Hard to do on this machine.
Would I chose gear over hydro next time? No way! This machine so nimble and controllable, I could never give it up. For close quarters, its amazingly handy. The 2501 will do any ground engaging and loader work you can throw at it, but If you need a lot of PTO power, the higher power model (3901) may be a better choice. I've had mine bog in heavy growth with both the 6ft finish mower and 5ft bush hog on and had to slow down to clear it out.
