Murph,,of course you could clamp something on it,you could also drill a few small holes and screw or bolt something to it,,and you could weld something to it,the question was,listen now,can the man weld somekinda bracket to roll bar to put a light on it,,WELD IT.
Hangfire,,know nothing about sueing people,but again the question was can he weld a little bracket or angle to bar,,not some hypothetical dooms day event that may happen or not down the road to someone at sometime. Some people must think this rollbar is made outta some speical steel that is strong,but if you put a little weld on it it turns to glass or something and I'm here telling you that ain't the case. Yeah,the manufactors got all kinds of rules and regulations and some for a good reason,cause they gotta assume the worst case and cover their @##,and some just cause some lawyer said if you say this most people won't read it and we got them if the time comes and we save money,,its a sue happy country made so by lawyers more than normal peoples greed. I'm just assuming the guy owns the tractor,and is an adult,with common sense,,also suggested to not do it if he was going to make a nasty weld with holes and under cut,,also assume its just a few inches at most of weld he is going to do,[he did say lights,not cutting bar into and making it longer or wider or something],,and I'm saying,he can do this safely,without worrying about the rollbar shattering or something else strange.
Roy,of course thats the reason people asks questions,,,I ask some myself,,but its nice to get the right answer,,this has evolved into a legal issue with manufactor,not if the guy can weld a light bracket onto his roll bar,,there may be reasons he don't want to,,just saying from a welding point of view,they ain't one,,,and again,that was the question. thingy
