What is a safe distance of over lap for a brush cutter drive shaft. In other words how far should the inner drive line stick into the outer drive line (min) and still be safe??????? 801; 45 hp diesel turning the shaft.
I bought this Bush Hog brand cutter with my tractor. I knew it had been re-decked in years past but the job looked OK. I planned to re-deck it again last winter but one thing leads to another and it got put on the back burner. (You do realize I am the worlds best procrastinator; Don't you) I also noticed the drive line was hitting each other (Or very close) when you raised the cutter and felt this was real unsafe so I did cut the shaft down a couple of inches last winter.
This past weekend I took the time to see just how bad this cutter deck is. Since I could hit it with a maul and punch holes in the deck I feel the re-deck job is past due.
So I am making a list of parts I need when I notice the blade swings about 1 1/2 inches in front of the cutter where the chain guard would go. Anyone what to bet this led to my driveline being to long.
Seems when the P O did the deck job he did not deck it but rather did a total rebuild. The problem is (I think) he put the gear box to far forward. So now I am thinking about rebuilding this cutter rather than decking it. This creates a problem because I have already cut the drive line; and moving the gear box back far enough to add chain guards and still leave enough room to clear the tires may make my driveline to short. I have thought about leaving the gear box in place; leaving the sides of the deck as they are; and adding a rounded front between the 3 point arms to move the chain guard forward here. I have also thought about just leaving it like it is and leaving the chain guard off like it has been in the past.
So throw me a bone here. Give me some ideas.
Sorry I got so long winded. Just making sure I include all the info needed to give me a answer.
