Freight Orders

Freight deliveries require a delivery time be scheduled and someone must be present at the time of delivery to inspect and sign for the merchandise. A representative from the freight carrier will call the phone number entered at checkout to schedule the delivery.

Liftgate Service

For freight deliveries, you have the option of adding a liftgate to your delivery. A liftgate is the device that lowers a product from the truck to ground level.

CPO recommends adding liftgate service for freight deliveries exceeding 100 lbs if you do not have a loading dock or fork lift at the delivery address. Additional charges may apply. The liftgate option will be presented during the checkout process.

Please note that liftgate service only ensures the product is removed from the truck. We recommend you have the additional help of two to four people to move the product to its desired location because drivers are not required to assist.

Requesting liftgate service after ordering may result in additional charges and delays.

Consumers Reports Wrong AGAIN

By Roland

from Michigan

Comments about Ariens Razor 159cc Gas 21 in. 3-in-1 Self-Propelled Lawn Mower:

Decided to not struggle with the Honda that Consumers Reports rated #1 any longer. The Honda was difficult to handle especially on hills..felt like it was going to tip over when traversing hills and was just plain dangerous when going up or down....heavy and awkward. A real handful and not at all user friendly. Looked at Toro, Snapper and Ariens...couldn't ignore the features and quality of the Ariens and purchased after returning to the dealer for a third time. The Ariens has not disappointed in any way...does a great job. The writer who complained about the height adjustment not holding better take the unit in for service...there's something wrong or broken. The writer who complained about the transmission guard dragging on the turf should tip the mower on it's side and observe what the guard is and how it functions. The guard is actually the height adjustment cross shaft and is at it's lowest point when the adjustment is set to it's highest setting. As the height is set lower the cross shaft rotates up into the deck and in no way can drag on the turf. I agree with several writers who complained about difficulty installing the side discharge is indeed difficult and takes some practice. I am surprised that no one commented on how one must drain the oil for an oil change...a messy job that thankfully is usually performed only once a season. If the Razor performs half as well as my Ariens snow blower has for three Michigan winters I'll be very happy. For the life of me I don't understand the low rating the Razor received from Consumers Reports


Very pleased

Comments about Ariens Razor 159cc Gas 21 in. 3-in-1 Self-Propelled Lawn Mower:

First of all, this is my first Ariens mower. Previously, I have owned Craftsman, Toro and Lawn Boy (both 2 and 4 cycle engined) mowers. Every mower I have owned has had good points and some idiosyncrasies that could be irritating. I purchased this mower based on recommendation of my local small engine shop. I have used this mower for approximately 3 months mowing as a bagger and as a mulcher of both grass and leaves. I think I have a good handle on its pros and cons. I am very pleased with the mower overall. The housing is heavy gauge stamped steel. By heavy, I mean it is at least twice as thick as what is used on the low priced units in the major chain stores. The engine is a Lorcin OHV. It starts on the first or second pull every time whether hot or cold, has good power and seldom bogs down even with a full bag and going uphill. The single lever height adjustment is a great idea. It is the best bagging mower I have owned. The vacuuming action is excellent and the bag has a large capacity and fills completely. The handle adjustment allows the handle to easily be raised to 90 degrees so the bag is easy to remove and replace. It does get a bit "tippy" when the bag is full but not as much as other rear baggers I have owned. The cut is very smooth with very few straggler grass blades. It seems to get better gas "mileage" than my old Lawn Boy. It mows faster than I'm accustomed to - you can mow at a normal walking speed and still get a good cut. Mulching is very good to excellent. The clippings are chopped very fine and clumping is minimal. If the grass is tall or wet, it does have a tendency to leave some visible clippings at the end of a pass or when making a turn. Mulching leaves works fine. The only criticism is that it tends to blow some of the clippings and leaves out the front just ahead of the right front wheel. This is not a problem unless the wind is blowing from the left and the leaves/clippings are blown to the side where the mower doesn't get them. I have used the side discharge very little, but it seems to work fine though the deflector is difficult to attach. I cannot comment on durability, but it appears well made from quality components. Now for the nit-picking. It is a heavy mower. I didn't weigh it, but based on lifting it out of my van (fully assembled) it felt heavier than my old Lawn Boy when I lifted it to haul it to the scrap yard. I'm guessing about 90 - 100 pounds for the Ariens vs 75 - 80 pounds or so for the Lawn Boy. It also feels heavier when using it. That makes it a bit harder to maneuver than my old Lawn Boy. It is not a quiet running engine (maybe a better muffler?). The speed control is a single lever on the right hand side of the handle and takes a bit of getting used to. The first time I used the mower, I squeezed the lever too hard and the mower took off like a scared rabbit. The lever is also hard to reach and control when making a sharp left turn or doing a 180 to the left. I would recommend Ariens engineers design a double lever control so it can be reached easily with either hand (the south-paws will appreciate that as well). It has a guard to protect the transmission (good idea). The problem is that it protrudes below the cutting height. The guard/transmission is under the left rear corner of the mower. If you set the mower much below 3 inches height, the guard will drag in the turf and you lose traction if you're mowing over some rough ground or when mowing along the edge of a sidewalk or driveway. You either have to mow with the guard over the sidewalk or driveway and not on the grass or mow with the right side wheels of the mower on the concrete and the guard well away from the edge of the turf. You need to be careful when installing the bag as it will fall off if you don't get it firmly in the mounting slots. The side discharge chute is difficult to attach. Last, the mulching plug for the bagging chute lets a few clippings slip by it and collect between the plug and the flap that covers the chute. That gets dumped in the driveway or on the lawn when you change from mulch to bag.

Comments about Ariens Razor 159cc Gas 21 in. 3-in-1 Self-Propelled Lawn Mower:

I replaced a TORO mower with the Razor no comparison the Razor starts easy and the self propelled drive allows me to make short work of cutting the grass. Next purchase an Ariens snow blower....
