Review from a former Honda owner
I've had two previous Honda self-propelled mowers prior to the TB340 XP and this mower has exceded all of my expectations!

So far I have one mowing season under my belt with the TB340 XP. It has worked flawlessly so far. I love the one pul, smooth, starts. And to think I was so spoiled previously with my Hondas and their electric start, starting is a breeze with this mower.

Our backyard is on a steep incline and the oversized wheels do their job and provide great traction even in wet conditions. Never have I felt the mower was underpowered even when mowing an overgrown and wet lawn.

I mow our lawn without a bag and it mulches with great ease.

I can recommend this mower without question.

Absolutely The BEST
Simply put... this is the BEST mower ever. Large rear wheels make hilly terain a breeze to mow. The larger grass bag means less dumping. One pull is great for starting. My 2 sons (11 & 15) argue over whose turn it is to mow the grass.
