Redesigned for Maximum Seed Protection and Improved Performance
Introducing the new J&M SpeedTender Pro™ 251 & 451 models. Both the 251 & 451 are designed to provide greater seed protection and improve performance. The new models are equipped with a poly-cupped auger and patent pending "Bottom-Less Pit" auger design. This industry exclusive combination has proven to be gentle on your seed for minimum damage and maximum germination results.
The 251 & 451 models also feature steep slopes for a quick and complete unload. Each chute has an initial 45° slope that quickly funnels seed from the pro-box to the steep 32° sloped chute to deliver seed to the unload auger. The tall 16'‑4" auger height allows you to easily fill your bulk seed tank, while the 3‑stage telescoping spout enables you to reach the widest planter box. The low 4'‑2" deck height makes loading and unloading boxes safe and easy. While planting season doesn’t always go as expected, you can trust the J&M line of seed tenders to deliver your seed fast and gently to increase your efficiency and profitability.
Low Deck Height
Safe & Easy Loading of Boxes
The J&M SpeedTender™ Pro 251 and 451 both feature a low deck height of 4'‑2". This design gives the J&M SpeedTender Pro a superior center of gravity and more stability during transport on uneven ground. The lower deck height allows the boxes to be loaded and unloaded at a safer and easier height.


Poly-Cupped Auger
Efficient & Gentle
The poly-cup interior flighting is cup shaped to gently and quickly carry the seed up the auger. In addition, the outer tube and flighting diameters are correctly sized to prevent seed from getting caught against the tube and cracking.
This design, in combination with the Bottom-less Pit, virtually eliminates the chance of cracking seed and gives you optimal performance for maximum germination rates when planting. This auger design rivals the performance of a typical round belt conveyor design, but without the inflated price tag.
SpeedTender Pro 251 & 451 models feature steep slopes for a quick and complete unload. Each chute has an initial 45° slope that quickly funnels seed from the pro box to the steep 32° sloped chute to deliver seed to the unload auger.


The engine is conveniently placed out in the open for easy access. You can rest assured knowing the 13 hp engine will keep your SpeedTender™ Pro 251 or 451 working when you need it.

Trouble-free guide plates make for quick and easy loading and unloading. The guide plates ensure your containers are always centered when changing out your seed boxes.


Turn your auger on and off and fold and unfold your auger wirelessly wirelessly with a 2‑function wireless remote (Lundell) in place of the standard wired control.

J&M scale systems allow you to precisely fill your planters. The scales for the SpeedTender Pro 251 & 451 offer an Intercomp LD720 monitor with bin tracking capabilities.

Grain wagons are essential to the productivity of farms during the harvest season. Used to transport grains from the field to storage, grain carts can increase productivity and protect the grain. When used during harvest, a grain wagon increases productivity by allowing for unloading without needing to stop the combine. When efficiency is essential, grain wagons are an invaluable tool.
Once the grain has been harvested and transported with a grain wagon, you’ll need to ensure you have a grain storage solution that protects your grain. At Avonlea, we are pleased to provide grain hopper bins and grain bin accessories that protect your grain. Contact a member of our team today and find bin monitors, aeration systems, and grain bin heaters to protect your grain during long-term storage.We look forward to helping you improve the efficiency of your farm.
