The wife was cutting lawn Sunday with her YTH 1848 XP Husqvarna lawn tractor. It's got 28? hrs. Bought new about 10 years ago...
She said it sometimes would just stop while cutting (forward motion) but would back up. Then it would work in forward again, she described it as "after being in reverse, and going into forward, it did nothing for a few seconds, then it would jerk forward" but became more so not going forward, but would always back up...
So today I pushed it in the shop, and she's right, no forward motion, but it does back up. So I pulled the deck, and raised the front up to see if anything looked out of place, or see if the belt was bad. Everything looked normal....
The belt is turning the fan on top of the transaxle. So there is power going to the rear. Don't know what else there is on these things to check..
Only other thing I thought of was "maybe" one of the key ways in the rear wheel-axle would have broke, and it was catching enough to let it back up, nope, there both good..
Any ideas? Be gentle now, it's her mower
