Thanks all for the responses. Bill I share your deep concern for safety - in retrospect my enthusiastic post sure did not sound like it. I do agree with Jim & others that only by showing our kids what's right & safe does the message get through - they are too distracted these days to count on talk. So I put him on the seat with me, just like I did on our boat years ago, and he learns because his hands are touching the controls, his backside is feeling the inclines, the wind's in his hair (wow I'm waxing poetic here). The biggest lesson he got then & now was that we do everything - everything - slow & steady, considering all the angles & options. He has proven he can handle a 30' boat - he will learn this the same way, a little at a time. I sincerely appreciate & understand your concerns & the risks - my approach is certainly not right for everybody. Thank you - I will remember your concerns.
Re the tractor & work ahead, I'm a little surprised at my dealer who didn't want to sell me a rear blade for snow & gravel driveway work, saying the FEL and box blade should do it all. After last weekend I can tell the box won't efficiently pull the side scrapings back into the drive, and the soft ditches on either side won't let me go 90 degrees to the drive & pull it in that way. I think I need a blade - one with both angle & tilt, 6 foot to cover the wheels while at an angle. Will I wish I got one with offset as well? Anybody have a specific recommendation?
2nd question - I pulled the box blade teeth up & used blade alone last weekend, thinking the old hard-packed gravel would just tear the teeth up. Am I babying it - would they handle the gravel OK? It's a Bush Hog SBX-600 blade & looks pretty tough compared to the competition, but I don't know its limits yet. And wow - I can see how easily you could put a tooth thru a tire if back-blading. Again, I gotta go slow, consider the angles... if this was simple & easy it wouldn't be near as much fun.
She's back in the shop getting the grapple installed - it came in late - then I'll take pictures. Thanks so much for all the help - Buckee
