The PTO shaft on my Land Pride RCF3696 rotary cutter is burning up discs. This PTO shaft uses the Comer 2 disc clutch.
The first replacement set burned up pretty quickly. I installed them and set the spring snug, then turned each one 2 full turns. I measured each spring with a caliper and adjust to get them all the same depth. So yeah that was frustrating. I had them adjusted to the same depth as the OEM setup.
The second set, installed this morning, also burned up. I did get a lot more use out of them, but nowhere near what they should deliver. I thought the heat from the first and second set of discs burning might have glazed the surfaces. When I had it disassembled I worked each mating surface over with my angle grinder with a flap-style sanding disc. I was pretty satisfied that the surfaces are now in good condition.
I snugged the springs, then turned each one down 3 1/4 turns. Measured with a caliper, adjusted. I was very conscientious about the deck height while I was working, but I did have some rough stuff I needed to cut down in my pasture. I worked about 6 acres and the shaft burned the discs and was spinning freely.
I just don’t understand what is happening. My tractor is a M5-111 and the original set of discs lasted 2+ years. In a week I have burned through 2 sets of replacement discs. I bought the discs from the parts counter at my dealer, the part numbers coming right out of the parts computer. Could my springs and nuts be damaged from the heat?
