Hi, guys, just this past Tuesday I received a Snapper 21'' mower for my birthday. I tried it out yesterday and decided to give a review on it. We'll start from the handle and controls down. 1) Handle and Operator Controls: The handle and controls are good quality. This has the typical throttle control, infinitely variable drive speed control, bail bar, transmission engagement lever, and the starter handle. The handle has a comfortable foam grip. All of this is shown in (picture 1). The only complaint I have for the handle is the little plastic covering that protrudes out over the starter rope hook (picture 2). If the cord isn't in the little pulley system, the cord cuts into the plastic. The pulley fell off on my older Snapper Commercial 21'', and you will see what I had to do to keep the cord from fraying (picture 3). The whole handle assembly is very sturdy, and even without the extra braces that the commercial 21'' has, it does not have any wiggle or play. 2) Drive System: All I can say is that I love the Snapper drive system. I've never had any problems with them, even on the other 2 Snapper mowers that we own. However, the drive disc is smaller and thinner on the Hi-Vac (picture 4) versus the drive disc on the commercial 21'' (picture 5). However, for the work I do, I do not see this as a problem. I love how this mower has a differential and infinitely variable drive control. These systems are low maintenance and easy to service. 3) Engine: The Snapper Hi-Vac 21'' comes with a Briggs & Stratton 725EX engine. It's 190 CC with 7.25 foot pounds of torque. It starts on the first or second pull...which is sometimes easier than the Honda GXV160 on the commercial 21''! (Picture 6) 4) Deck/Mowing Abilities: This mower is built with quality construction. The hi-vac deck is strong, and the hi-vac blade that completes it makes bagging very effective. I have not yet had any yard to try out the mulching abilities on for this particular mower, but I'm sure that it is just as good as the commercial 21'' (they have the same blade). 5) Miscellaneous Specifications/Items: The Snapper Hi-Vac 21'' is 85 pounds, 15 pounds lighter than it's commercial 21'' counterpart. You can definately feel it. The plastic wheels are high quality and if they need replacing, Snappers are pretty much universal, so I bet some heavy duty steel wheels will fit on there just fine. As with most Snapper 21'' mowers, they have solid steel front and rear axels. The only problem I had was with the back right hight adjuster. It seems as though the axel shimmies to the left, resulting in the hight adjuster not wanting to disengage. I had to simply pull the wheel/axel to the right, and that freed the adjuster right up. The grass bag has a big hinged door that swings open easily for fast dumping of clippings. 6) Conclusion: Get this mower or get the Ninja mulcher version! These Snapper mowers are built old school, with good quality construction. With nearly maintenance free drive systems and well thought-out controls at the finger tips, plus good engine choices, these are the mowers to get. I hope this helps you guys out! Thanks, Will.
