Arnold MTD 490-900-M059 Rear Suitcase Weight for Murray Troy-Bilt Yard-Machines XP Pony Horse Bronco 50 775S 795S 762F 42 36

What It Is

The Arnold MTD 490-900-M059 Rear Suitcase Weight is a bolt-on counterbalance accessory designed to improve traction and stability on lawn tractors, especially when towing heavy loads, climbing slopes, or using a front-mounted attachment like a snow blade or sweeper. It adds 42 pounds to the rear of the tractor, helping prevent rear-wheel spin and front-end lift.

Fitment & Compatibility

Before buying, verify your tractor’s model and deck size. This weight is OEM-compatible with MTD-built brands including Murray, Troy-Bilt, Yard Machines, Yard-Man, and Bolens, as well as specific models like the XP, Pony, Horse, Bronco, and 50/775S/795S/762F. It fits most 42-inch and 36-inch deck tractors from these lines. However, it will not fit Craftsman, John Deere, Husqvarna, or Honda tractors without modification. Check your tractor’s rear hitch plate – it requires two existing bolt holes (usually 3/8-inch) spaced 8 inches center-to-center. Measure yours to confirm. The weight is a direct bolt-on; no drilling or adapter needed if your tractor has those holes.

Key Things to Know

• Quality & finish: Cast iron with a durable black powder coat. Weighs exactly 42 lbs. Handles and bolts are included; no extra hardware needed.
• Installation: Easy. Remove the two bolts from the rear hitch plate, slide the weight on, and reinstall bolts. Torque to 20–25 ft-lbs. One person can manage it, but two is easier due to weight.
• Common gotcha: On some newer Troy-Bilt Pony models, the rear hitch plate may have plastic inserts that need removal first. Also, if you have a rear bagger, the weight may interfere – check clearance before buying.
• Traction vs. stability: It helps with snow plowing and towing, but won’t fix a poorly maintained lawn or low tire pressure. Pair with aggressive tires for best results.

Should You Buy It

If you own a compatible MTD-built tractor (especially a Troy-Bilt Pony or Murray) and frequently deal with hills, snow removal, or heavy trailers, this weight is a solid, affordable upgrade. It’s well-reviewed for build quality and ease of install. Skip it if you have a different brand or a rear attachment that blocks the mounting area.
