jrpoux, I have never intentionally pushed anything with the grill guard/bumper. Glad to have a sturdy grill guard, though as when I use ropes, straps, or chains to hoist something up with the pallet forks and it swings a mite, it is comforting to have a sturdy grill guard between the pendulum and the expensive front end of the tractor engine compartment.
I do push things with the pallet forks platform and of course with the FEL, either of which may be in place while brush hogging to save smacking into stout things with the axle guards first. I have bent the axle guards pretty badly running over trees and destroyed the rubber thingies over the balls in the steering (in front of axle). Wonder why they don't put the steering behind the axle for protection. Anybody? (Kubota Grand L-4610HSTC)
Have new guards on order and will pound out the old ones to place over the new ones and to increase the lateral coverage as I think there is too much exposure of steering parts to hiting things you drive over (like trees). Yeah, I know, I shoulda bought a tank. Anyway, if I had a bumper, I'd bumber in the morning, I'd bumper in the evening, all... oops, sorry If I had a bumper it wouldn't help me at all. If it were low enough to help it would be in the way a good deal of the time. Maybe a hydraulic adjusted bumper, top'n'tilt for the front? Seriously, I think looking to see what might be damaged and protecting that with a skid plate or metal cover is way better than a bumper for what I have experienced. I only have 100 hrs on this one tractor and all previous experience was N O T tractor seat time. Perhaps someone else has experience that favors some kind of bumper.
What were you thinking of pushing? I have seen trailer hitches in front of tractors and that seemed to work well for accurate manuevering in tight spaces but have never seen anything pushed by a tractor.
