Rear Discharge vs. Side Discharge: Why Choose a Rear Discharge Mower?

Exmark Lazer Z Rear-Discharge

A rear-discharge mower offers numerous advantages, not the least of which is the ability to trim on both sides of the deck.

An increasing number of Exmark mowers are now available with our UltraCut Rear Discharge cutting deck. And as our customers learn more about the advantages of a rear-discharge mower, they’re choosing the option more and more.

Today we’ll talk through the reasons somebody would choose rear-discharge riding mowers over the more common side-discharge mowers, and what cutting conditions rear-discharge commercial mowers excel in.

Reason 1: increased clipping control

Rear-discharge decks send clippings out behind the deck, under the mower, instead of through a side-discharge chute. The operator stays cleaner and clippings are distributed uniformly over a wider area. Rear-discharge decks also reduce the potential for debris or foreign objects to be discharged at dangerous velocity, making them a popular option with municipalities as well as parks and recreation departments.

Reason 2: increased cutting efficiency

With one counter-rotating blade, the UltraCut Rear Discharge cutting deck offers increased cut quality and even clipping distribution.

The UltraCut Rear Discharge deck reduces clipping over-processing using a counter-rotating blade design and patented Flow Control baffles. Because clippings are cut once and discharged, a rear-discharge deck uses less horsepower than an equivalent side-discharge deck, which must pass clippings from blade-to-blade to be discharged. As a result, rear-discharge is a great choice for cutting taller grasses and in rougher cutting conditions, so they are an appealing choice for use on farms or acreages.

Reason 3: ability to trim on both sides of the deck

Whether you’re a landscape professional looking to maximize productivity, or an acreage owner looking for maximum versatility, the ability to trim on both sides of the cutting deck is a big advantage for a rear-discharge mower. No longer must you plan your entire mowing pattern based on the location of landscaping. Now, you simply take the most efficient route and get the job done faster.

Reason 4: reduced noise

The decreased noise and increased clipping control of a rear-discharge mower are ideal for maintaining residential properties.

Discharging clippings behind the deck, under the mower, dramatically reduces the noise level of the deck for both the operator and for bystanders.

For those looking for additional noise reductions as well as an increased quality of cut for the most highly manicured appearance, Exmark offers its Finish Cut baffle kit for the UltraCut Rear Discharge deck. It’s perhaps the ultimate combination of cut quality, productivity and clipping control.

Bagging is perhaps the one challenge that the UltraCut Rear Discharge deck doesn’t tackle. That said, our Navigator – a dedicated bagging machine – uses a rear-discharge deck, so if you’re committed to bagging and like the benefits of rear-discharge, it just may be the rear-discharge commercial mower you’re looking for.

The UltraCut Rear Discharge deck is available on select Pioneer and Lazer Z rear discharge mower models. Visit to learn more about Exmark’s entire line of UltraCut decks.
