I have a Kubota without the cab and a t503 with a cab, all I can say Is I love that cab, I try to use various attachments as my excuse for not getting out of the cab, If tree branches are to low, just use my tree puller, reach up as high as possible and break off the branch, also make sure that your implements are wider than the tractor or just shift them over to one side and only pass that side near the fence or tree line.
Two weeks ago I removed an old stump with my tree puller and all of a sudden a swarm of hornets covered the cab and all I could think of was thank God for the cab, LOL
Staying out of the rain, dust, heat, cold, sun, and insects will make a cab believer out of you.
