Gravely Zt42
I Have Had My Gravely Z2148 Mower For About 10 Years Now and Have Cut About 1 to 2 Acres With It. This Mower Has Been Abused At Times and Never Has Given Me a Problem, My Certified Mechanic Will Not Even Change the Belt Yet Because He Says It Does Not Need It Yet Even After 10 Years. the Engine Is a Kohler and All I Do Is Change the Oil. I Do Not Think Any One Can Buy a Better Mower For the Price as a Gravely.

New Gravely Zt 42
I have .75 acres to mow and have been using a garden tractor mower for years. I mowed the lawn today and now almost look forward to mowing weekly. It did the uneven sections as easily as the flat areas. The 3 blade system does a much better cut than my old 2 blade 42" mower. Takes a light touch on steering, but wish I had bought one 60 years ago. Best money I spent on the yard in my life.

Quality Mower
After a month of shopping around for a new lawn mower, I decided on the 2014 Gravely ZT 42 for a number of reasons. It not only looks awesome, but it is also built very well out of heavy gauge steel. After mowing the lawn, I was satisfied with a job well done. Much better than my 16 year old Snapper...ever did.
Great looking machine, quality built. Mows like a dream. It might cost a little more... but well worth it in my opinion. Check them out!!!!!!

Paint Problems
Purchased the Gravely in the summer of 2009. Mower is used for only one yard of less than one acre. By 2011 it began to lose paint in a couple of areas. It didn't seem to be a problem but every summer there were more areas with missing paint chips. In 2013 I contacted my dealer and they agreed that this should not have happened. To their credit they tried to get Gravely (Ariens) to do something about the problem but were unsuccessful. They suggested that I contact Gravely's customers relations... more
Cons: Low Quality, Expensive, Poor Service From Manufacture

Very Disappointed
I was expecting the best grass cut of my life. First I noticed burnt spots on my lawn after using it for the first time. I contacted Gravely and they told me I needed a heat shield for my muffler (I scratched my head and wondered why doesn't this 5K mower come with a heat shield if they are aware of this problem).

Secondly I purchased the mulching kit which was a few hundred dollars extra and after my fist cut I noticed strips of uncut grass after each pass. Ok, so I contacted Gravely again.... more
