I bought a kubota mower deck for my older model kubota tractor about 3 month ago. During the leaf season. This 60" inch deck has 4 rubber wheels on the sides and a round on in the front center and a smaller one in the rear center underneath the deck. Talk about poor engineering!!!! The older decks had an adjustable wide roller sitting outside the rear center. The mechanics said they change this because grass clogged in the roller. I had one and it rarely did that. How stupid this new design is. YOU have to cut at 2-1/2" if the ground has any un level areas. If the ground rolls in anyway the cut is uneven even at the above height. And it still scalps at that height!! That height is too high for crab grass and weedy yards. The little roller especially where it is locate will lock down and will not support the deck leading it to scrub the ground. The dealor is in denial. But the mechanics say the have had other complaints. I swear my dealor is becoming more and more like a used car dealorship. The mechanics will only whisper becausethey dont want to be heard telling the truthe. And they are a high priced dealorship to begin with compared with the prices I have seen on here. After I showed them the problem they said there was nothing they could do for me. At first they said it would be 2 weeks before they could look at it. I just had spent alot of money with them and have in years past.
