Grading MX6 Blade Changes?

[mars1952]

Folks -

This is my first year to do the checkup on the MX6 and I'm wondering how I should go about safely elevating the unit so I can check the blades, etc., under there. The manual shows putting it on Jackstands, but I don't think I'll be doing it that way....

Any thoughts and best practices to share?

Thanks!

Hi Bob: When I need to inspect my MX5 blades I back up so that the mower is overhanging a bank. When I changed the blades and main seal I unhooked the mower from the tractor and stood it up on the 3PH brackets and chained it to the FEL. When you change the blades you will need a 3/4" torque wrench. The torque spec on the blade bolts is 728 ft lbs My 1/2" impact wrench (600 ft lbs) would not break loose the nut. I had to use a 3/4" breaker bar with a cheater bar. I now have a 3/4" impact wrench for the next blade change. If you don't have a 3/4" torque wrench you should take it to the dealer to get the torque checked or just have them change the blades for you.
Good Luck, Marshall

Marshall -

Thanks. I've got hydraulic wrenches that I think should work so I can get the blades off - the idea of tipping it like that makes good sense. I will be testing out these possible approaches soon - my biggest interest was seeing what others were doing (safely) to get in there and change things out.

On my MX6 I'll run the 3 PT up as high as she'll go and place two jack stands,one on each side of the mower and go under on a creeper. The 3PT holds her up ,the jack stands are just for safety.

I use a 1/2 IR impact 600lbs to take off and put on the blades never have had a problem. I put a dab of grease on the threads of the blade bolts and the collar of the bolt the blade rides on and have never egg shaped the holes. I have over 2500 hrs on a Rhino Twister TW72 and over 1500 hrs on my MX6 and both are still running the original blade bolts and nuts. I replace or sharpen the blades about x3 times a year on both mowers.
