Why stand on a mower?
On a stand-on, you ride upright on a platform at the back. It's easy to step off to move a branch or open a gate, then step right back on. You steer with lap bars, the same as a sit-down zero-turn. Lawn crews use stand-ons on lots cut up by fences, beds and gates. They suit an owner with that kind of yard just as well.
The 434 is the narrow one. A 34-inch deck slips through gates and side yards a wider mower can't. The 448 gives you 48 inches for more open ground. Both cut from 1.5 to 4.5 inches. They share the lap bars and the transmission, so moving from one to the other is easy.
Which one fits you? Measure the narrowest gate on your route. If a 48 won't clear it, look at the 434. If it clears with room to spare, the 448 cuts the open stretches in fewer passes.
What the 434 and 448 share
The engine's a Kohler 7000 Series PRO KT724 of 747 cc, rated at 24 hp. It drives through a Hydro-Gear 3100 at up to 7 mph forward and 3.5 mph in reverse. The tank holds 5.4 gallons on both.
The deck is a 10-gauge shell with 7-gauge reinforcement top and bottom. Front tires are 11x6-5 on both. In back, the 434 runs 20x6.5-10 and the 448 runs a wider 20x8-10.
A stand-on works in its own dust, so don't let the air filter go. It's an inexpensive part that protects an expensive engine. Need a deck past 48 inches? The PRO X 600 Series runs up to 60.

Questions people ask
How wide is the deck on Cub Cadet's PRO X 434?
It's 34 inches, the narrowest deck in the PRO X 400 Series. That's the size for gates and side yards a 48 won't fit through. It runs the same Kohler engine and Hydro-Gear 3100 as the 448. Its rear tires are 20x6.5-10, and you'll cut from 1.5 to 4.5 inches.
What top speed does Cub Cadet list for the PRO X 400 Series?
It's 7 mph forward and 3.5 mph in reverse, on the PRO X 434 and PRO X 448 alike. Both drive through a Hydro-Gear 3100 transmission. Both carry 5.4 gallons of fuel. If you want more speed on a stand-on, look at the PRO X 600 Series.
Does Cub Cadet's PRO X 448 have a suspended platform?
No. Cub Cadet lists no suspension on the PRO X 434 or the PRO X 448. The 448 gives you a 48-inch deck, the same 24 hp Kohler as the 434 and a 5.4-gallon tank. If a sprung platform matters to you, the PRO X 648, 654 and 660 EFI have one.
How much does a Cub Cadet PRO X 400 Series mower cost?
We keep current pricing on our live inventory page at j5tractors.com, where our Conroe, Navasota, Normangee and Buna stores list the Cub Cadet mowers they have.
