I bought a John Deere zero turn (basic model) based on recommendations. After spending $2400 on the mower, I do not like the quality of the cut. Some rows appear almost shaved, others look like the grass has been pushed down. The latter issue is the most irritating.
I tried running the mower at highest throttle -- no improvement. I talked to the John Deere dealership about a mulcher blade - too expensive. I talked to a client who owns a lawn-mowing business; he suggested having the blades sharpened, even though I just bought the machine last April (2016). Today I went to a lawn mower shop; the proprietor suggested that I buy a blade with a higher lift.
Lawn mowing season is just a few weeks away and I have no idea what to do. Any suggestions?
You should be running the mower at the Highest throttle setting all the time, mowing and transporting. If your looking to buy blades for the mower that will last I'd look into getting a set of Oregon G3 Gator Blades and they will help with the mulching aspect if your concerned with that. What ever blades you buy I'd make sure to stay with the Oregon Blades. The G3 blades are a high-lift mulching Blade for a residential mower.
If you look to go back to the regular or standard Blades for the residential mower they should be replaced yearly or the start of every mowing season and not sharpened. Generally speaking the original blades that come on the mower aren't worth sharpening anyway.
I'd slow down the mowing pace to about half the maximum ground speed of the mower for the best cut and let the mower have time to do the job it was designed to do.
The thing you need to remember with the residential mower as with a commercial is there designed with a bts to only cut so many feet per minute and what happens with most people is they try pushing the mowers to fast and the result is they end up with a terrible looking job, and wonder why.
As Primerbulb 120 already said don't remove the grass chute, it wont help your problem any. A chute is a must to have on any mower.
