I just picked up a 721 Skidsteer. It has leaking seal in the front left axle and a leak from the right rear axle. The front one doesn't look like a big job but the manual says to remove the motor to replace the rear. Has anyone ever done the seals on a 721? How big of a job is it to replace the rear seals??????

Axle seal replacement is a big job, even the front ones will be hard, its a 2 person job! don't even attempt it on your own.
I have never replaced seals on a 721, i have done 2 743's and my 731 was the exact same setup.
In the 743 and 731 machines you really need to remove the hydro pump to gain access to both inspection plates so you can reach the rear sprockets. I was pretty sure most early *7* series machines were basicaly the same but i have been informed they have their differences.
