Thanks for the chain idea Eric. I took a 14' 3/8" logging chain ($23) and cut it up. The chains in no way effect the performance of the mower in anyway. I have two of these sulkies. One chain drive and one w/o. Where the chains hang there was two bakelite rollers there. It looks like the sulky was made to hang chains. But since I went to the larger castors and tires they where not in play. By having the chains on the sulky I can stripe with any size mower in the fleet.
