Hey guys, I have a Honda HRR2168VKA, S/N MZCG-8572705, bought NIB at Home D about 3 years ago. The rear wheel drive has become really weak. I can pick up the back end and the wheels will turn but as soon as it hits the ground and gets loaded, they stop. I did work fine for the first two summers. The wheels are not spinning inside the tires, the belt looks to be OK, it's not broken anyway, and I can't tell what could be wrong. The transmission pivots on the axle when the lever is pulled, like it should I guess. I opened the transmission and checked the gears and fluid level, that looks good as new. The cable is good to go. I've checked all over google trying to find a resolution with no luck. I've ordered a new belt to try, maybe mine's stretched. But, I measured it at 37.5 inches, and a replacement was listed at 38.25, so if anything, mine's too short or at least within spec. Any ideas would be greatly appreciated!
