I was reading the post in the tracked machine section about the drive motors and I'm curious if the motors on my 435 are the same as the larger Bobcat track machines. I have no problems now and will check the fluids when I bring it home. I am only changing fluids every 500 hr with a change at 100 hrs after I got it according to my manual. Sure appreciate tips on what to look for also looking forward to what travel motor to actually use. Bobcat specs straight sae 90 wt gear lube with a capacity of .55 qt. Its a 2006 model so mabe they made a change with the 435 Fast-track. Thanks Scott
